Description

Compressor memory system, compressor information network and warranty management method

technical field

The present invention relates to compressors, and more particularly to compressors with memory systems.

Background technique

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Compressors are used in a variety of industrial and domestic applications to circulate a refrigerant within refrigeration appliances, heat pumps, HVAC or refrigeration systems (commonly referred to as "refrigeration systems") to provide a desired heating or cooling effect. In various applications, it is desirable for the compressor to operate stably and efficiently to ensure the normal operation of the refrigeration system. For this purpose, the compressors can be operated via the associated protection and control systems.

The protection and control system monitors operating signals generated by compressor or refrigeration system sensors and determines compressor or refrigeration system operating data. For example, protection and control systems can determine if a compressor or refrigeration system failure has occurred. However, such data may be lost when the protection and control system is turned off, and/or when the protection and control system is no longer associated with the compressor.

Specific protection and control systems are compatible with many different compressor models and different capacity types. Traditionally, compressor characteristic data including, for example, numerical constants corresponding to compressor model, type and capacity have to be loaded into the protection and control system during installation. Such compressor data is generally published by the compressor manufacturer and is used during refrigeration system design. This compressor data can be used by the protection and control system during compressor operation to control, protect and/or diagnose the compressor and/or the refrigeration system.

Loading compressor data into the protection and control system is an additional step performed on site by the installer. Errors made by the installer in the field when loading compressor data may not be immediately apparent, but may cause operational problems with the compressor or refrigeration system in the future. Also, if the protection and control system or the compressor is replaced, the compressor data must be reloaded. In practice, such compressor data may be lost when the protection and control systems are no longer associated with the compressor.

A junction box 30 having a junction box cover 32 may be attached to the housing 12 .

The junction box 30 may house a protection and control system 34 . The protection and control system 34 may have a protection and control system housing 36 and an integrated circuit (IC) 40 with a processing circuit 42 .

Memory system 45 may include a memory connector 48 to which non-volatile memory 46 is connected. Non-volatile memory 46 may contain compressor characteristic data including, for example, numerical constants corresponding to compressor model, type, and capacity. In other words, certain compressor product series or identification information may be stored in non-volatile memory 46 .

The non-volatile memory 46 may remain within the sealed connector member 44 attached to or embedded within the compressor 10 throughout the operating life of the compressor 10 . In this way, whether the compressor is moved to a different location, returned to the manufacturer for repair, or used with a different protection and control system, the compressor characteristic data can be stored in the non-volatile memory 46. way with the compressor 10 .

Alternatively, the non-volatile memory 46 may be located within the compressor 10 or within a tamper resistant housing elsewhere on the compressor 10 .

For example, non-volatile memory 46 may be a 2 kilobyte or 4 kilobyte erasable programmable read-only memory (EPROM) chip or an electrically erasable programmable read-only memory (EEPROM) chip. Other types and sizes of memory devices may be used, including flash memory, magnetic media, optical media, or other non-volatile memory suitable for storing data. Additionally, RFID devices may be used. The RFID device can include non-volatile memory and can transmit data wirelessly. If an RFID device is used, the memory connector 48 may be a wireless data communication device allowing communication with the RFID device.

Non-volatile memory as used herein refers to memory, such as EPROM or EEPROM, that retains its data content when power is no longer applied to it. Additionally, non-volatile memory may include conventional volatile memory configured with an independent power source to retain data. For example, random access memory (RAM) may be used and embedded within compressor 10 with an independent power source such as a battery with an expected battery life greater than the expected operating life of compressor 10 .

The IC 40 may be configured with an IC connector 50 such that the IC connector 50 may be engaged by the memory connector 48 when the protection and control system 34 is connected to the sealed connector part 44. As such, non-volatile memory 46 may communicate with processing circuitry 42 through IC connector 50 and memory connector 48 . Processing circuitry 42 may read from or write to non-volatile memory 46 .

Non-volatile memory 46 may receive power from memory connector 48 and protection and control system 34 or other devices connected to memory connector 48 . In this way, non-volatile memory 46 may not require a separate power source.

The sealed connector part 44 may be provided with three power inlets 47 electrically connected to internal compressor components such as a compressor motor (not shown). Three-phase power may be delivered to the compressor 10 via a power cord 52 received by the junction box 30 . A power cord 52 may be connected to the ends of three conductive posts 54 through holes 37 in the surface of housing 36 . The sealed connector component 44 can receive three conductive posts 54 . Each of the three conductive posts 54 may be connected to respective phases of the three-phase power carried by the power line 52 . When installed, the power inlets 47 can be bent so that the holes in each power inlet receive one of the three conductive posts 54 . In this way, the power lead 47 can be electrically connected to the conductive terminal 54 and three-phase power can be delivered from the power lead 52 to the compressor 10 .

While three-phase power is illustrated as being supplied to compressor 10, compressor 10 may alternatively receive single-phase power. Additionally, any system for delivering power to compressor 10 may be used.

Power may also be delivered to IC 40 and processing circuitry 42 via at least one of conductive posts 54. While compressor 10 may be powered by a three-phase power supply, IC 40 and processing circuitry 42 may be powered by single-phase power from one of conductive terminals 54.

Processing circuitry 42 may receive various operating signals generated by compressors or refrigeration system sensors. Processing circuitry 42 may determine or derive compressor or refrigeration system operating data. A current sensor 56 may be located on IC 40 and may generate a current signal corresponding to the amount of current drawn by compressor 10 . Processing circuitry 42 may monitor the current signal generated by current sensor 56 . Typically, the level of current drawn by the compressor corresponds to the current load on the compressor. Generally, the current drawn by the compressor 10 increases as the current load on the compressor 10 increases.

Additional compressor sensors may be located within compressor housing 12 . Such internal compressor sensors may include motor temperature sensors, discharge pipe temperature sensors, suction pressure sensors, and the like. Another sealed connector component 58 is fixedly connectable to the compressor housing 12 and is provided with conductive terminals 60 connected to various internal compressor sensors. Processing circuitry 42 may receive operating signals generated by internal compressor sensors. Processing circuitry 42 may also receive additional operating signals from additional systems or compressor sensors external to compressor 10 . Based on the various operating signals, processing circuitry 42 may determine the operating mode of compressor 10 and may generate a compressor or system failure alert.

The protection and control system 34 may be configured with a communication terminal 62 connected to the processing circuit 42 through an aperture 63 in the surface of the housing 36 . Communication terminal 62 may be connected to many networks/communication devices. Communication terminal 62 can be connected to a hand-held Computing device, system controller, or other suitable communication/networking device and communicates therewith.

Referring now to FIG. 5 , a flow diagram illustrating a data access control algorithm for memory system 45 is shown. Initialization data, including compressor characteristic data, may be loaded into the memory system 45 in a combining step 98 prior to normal operation. When compressor 10 is initially assembled and configured with memory system 45 , for example, a compressor manufacturer may load compressor characteristic data into memory system 45 in step 100 . The compressor characteristic data may include manufacturing data related to the particular compressor 10 associated with the memory system 45 .

For example, initialization data may include compressor model number, serial number, and capacity size. A bill of materials (ie, a list of part numbers for all the individual components of the compressor) can also be loaded into the memory system 45 . It is also possible to load manufacturing drawings or the sequence of operations performed when assembling the compressor 10 . Data regarding dates, shifts, equipment, assembly lines, and inspectors who manufactured and inspected the compressor 10 may also be loaded.

Compressor characteristic data may also include test data information loaded into memory system 45 by the compressor manufacturer. The test data may include an energy efficiency ratio that relates the compressor's BTU/Hr to input power expressed in watts. The test data may also include a low voltage start number, which represents the lowest line voltage at which the compressor 10 can be started. The test data may also include wattage related to the electrical power that may be input to the compressor 10 . The test data may also include the maximum current drawn by the compressor 10 at maximum load. Test data may also include the flow of refrigerant under given test conditions.

Compressor characteristic data may also include compressor operating factor data. Each compressor 10 is associated with certain compressor specific numerical constants which are used by the protection and control system 34 in making certain calculations and determining operating data. For example, protection and control system 34 may use compressor specific numerical constant to calculate data on other refrigeration system components.

For example, protection and control system 34 may determine the condenser temperature or evaporator temperature based on the following formula:

(1) $P=C_0+(C_1\×T_{\mathrm{COND}})+(C_2\×T_{\mathrm{EVAP}})+(C_3\×T_{\mathrm{COND}}^2)+(C_4\×T_{\mathrm{COND}}\×T_{\mathrm{EVAP}})$

where P is the compressor power, T _COND is the condenser temperature, T _EVAP is the evaporator temperature, and C ₀ to C ₉ are constants specific to a particular compressor model and size.

Likewise, the protection and control system can determine the compressor capacity according to the following equation:

(2) $x=Y_0+(Y_1\&times;T_{\mathrm{COND}})+(Y_2\&times;T_{\mathrm{EVAP}})+(Y_3\&times;T_{\mathrm{COND}}^2)+(Y_4\&times;T_{\mathrm{COND}}\&times;T_{\mathrm{EVAP}})$

where X is the compressor capacity, T _COND is the condenser temperature, T _EVAP is the evaporator temperature, and Y ₀ to Y ₉ are constants specific to a particular compressor model and size.

The numerical constants C ₀ to C ₉ and Y ₀ to Y ₉ traditionally issued by the compressor manufacturer and loaded into the protection and control system 34 on site when the compressor is installed can be determined by the compressor manufacturer when manufacturing the compressor 10 It is preloaded into the non-volatile memory 46 of the memory system 45 . In this way, the compressor characteristic data is loaded into the memory system 45, thereby reducing the installation burden on the field installer and minimizing the chance of installation errors.

Information about the particular refrigeration system connected to the compressor may be loaded into the memory system 45 in step 102 by the system manufacturer. For example, a refrigeration system manufacturer may receive a compressor 10 configured with a memory system 45 that has been loaded with compressor characteristic information by the compressor manufacturer. A refrigeration system manufacturer may then use the compressor 10 as a component in a refrigeration system having, for example, an evaporator or a condenser. A refrigeration system manufacturer may load refrigeration system information into the memory system 45, such as part model and serial number information for system components such as evaporators and condensers.

The installation data may be loaded into the memory system 45 in step 104 by the installer when the compressor is installed in the field. As mentioned above, the memory system 45 is configured with a memory connector 48 . The memory system 45 is field accessible by the installer through a handheld device connected directly to the memory connector 48 . Optionally, memory system 45 may be accessed after protection and control system 34 is installed. In this case, the installer can access the storage system 45 through a handheld device connected to the communication terminal 62 of the protection and control system 34 . As such, memory system 45 is accessible by the handheld device through communication terminal 62 , processing circuit 42 , IC connector 50 and memory connector 48 . Similarly, memory system 45 may be accessed by other devices connected to communication terminal 62 of protection and control system 34 .

The installation data loaded into the memory system 45 may include the location of the installation, the date of installation, the name of the installer and the dealer from which the compressor 10 was purchased. Additionally, after installation, if the compressor 10 has been serviced, service information such as service instructions and a list of replacement parts can be loaded into the memory system 45 in the same manner at that time.

With continued reference to FIG. 5 , once the compressor 10 has been installed in the field, the compressor 10 may be brought into normal operation in an assembly step 106 . The normal operating cycle is generally as shown in grouping step 106 . During normal operation 106 , compressor 10 may perform operational functions in step 108 . During normal operation, protection and control system 34 may monitor operating signals generated by compressor or refrigeration system sensors and may generate compressor or refrigeration system operating data. Protection and control system 34 may determine the mode of operation of compressor 10 and may determine if a compressor or refrigeration system failure has occurred.

During normal operation, protection and control system 34 may write operating data into memory system 45 in step 110 . In the memory system 45 using 2 kilobytes or 4 kilobytes of EEPROM, the operation data of the last 2 to 3 minutes of operation can be stored in the memory system 45 . If a memory system 45 with a larger amount of memory is used, longer periods of operating data can be stored. When the memory allocated for storing operating data is full, the protection and control system 34 can write data by overwriting the oldest operating data first. Additionally, protection and control system 34 may divide memory for storing operating data into discrete segments. When the allocated memory is full, the oldest segments can be erased and rewritten with newer operational data.

The operating data written to the memory system 45 may include any number of predetermined signals and parameters monitored or generated by the compressor, refrigeration system, or protection and control system 34 . For example, operating data may include information related to current drawn, compressor voltage, ambient temperature, discharge pipe temperature, suction pipe temperature, compressor motor winding temperature, compression element temperature, bearing temperature, oil temperature, discharge pipe pressure, suction pipe pressure, etc. and other related data. Operating data may also include refrigeration system data such as condenser temperature and evaporator temperature. Operational data may also include refrigeration system communication inputs, such as refrigeration system calls for cooling or heating, defrost commands, and the like.

Fault history data may also be stored in memory system 45 . Protection and control system 34 may determine whether compressor 10 or system failure has occurred in step 112 . When a fault occurs, the protection and control system 34 may update the fault history data in the memory system 45 in step 114 . Fault history data may include information regarding the date, time and type of the most recent fault. For example, seven days of fault history may be stored in memory system 45 . Information related to the most recent fault (such as compressor motor temperature of most recent fault, voltage or current of most recent fault, oil level of most recent fault, cycle number of most recent fault, etc.) may be stored in memory system 45 .

In step 116, protection and control system 34 may determine whether a device connected to communication terminal 62 has made a request for memory system data. When a device requests data from memory system 45 through communication terminal 62 , protection and control system 34 may retrieve the requested data from memory system 45 at step 118 and provide it to the requesting device through communication terminal 62 . The protection and control system 34 then returns to step 108 .

As such, compressor characteristic data, system data, installation data, and operational data may be stored in memory system 45 and accessed by protection and control system 34 and any other device connected to protection and control system 34 through communication terminal 62 .

Data stored in memory system 45 may be used to estimate compressor performance or refrigeration system performance. For example, by examining the data stored in the memory system 45, operating data can be estimated based on the compressor model and capacity and where the compressor is installed. Data stored in memory system 45 may provide insight into compressor operation based on various factors that may affect performance and specific compressor specifications. In this way, the data stored in the memory system 45 can provide an estimation aid when considering the purchase of a new compressor or when designing a new compressor.

Protection and control system 34 may be connected to the network through communication terminal 62 . In this case, memory system 45 is accessible by other devices connected to the network. The compressor characterization data, system data, and operating data are then used to diagnose the compressor, diagnose the refrigeration system, plan repairs, and estimate compressor warranty claims.

Referring now to FIG. 6 , a compressor information network 150 is shown. The protection and control system 34 or multiple protection and control systems 34 may be connected to a network. The protection and control system 34 is connectable to the network through a communication terminal 62 communicatively connected to the processing circuit 42 . Optionally, protection and control system 34 may be connected to the network through system controller 152, such as a refrigeration system controller. Additionally, protection and control system 34 may be connected to the network through handheld computing device 154 or other suitable network device. Protection and control system 34 may be connected to Internet 158 via wired or wireless Internet connection 160 .

Protection and control system 34 may be connected to a computer network such as Internet 158 . Additionally, protection and control system 34 may be connected to database server 156 via Internet 158 . Database server 156 may be a module configured to communicate with protection and control system 34 and a computer information database stored in computer readable medium 164 . As such, the contents of memory system 45 may be accessed by other devices connected to the network, including database server 156 .

Database server 156 may collect information from memory system 45 through memory system information processing initiated by database server 156, protection and control system 34, system controller 152, handheld computing device 154, or other network device. The database server 156 may build a comprehensive database of compressor information based on the contents of the plurality of memory systems 45 connected to the network. Thus, database server 156 may store compressor information including compressor identity, location, operating history, maintenance history, failure history, failure data, etc. for a plurality of compressors 10 connected to a network and located in various locations around the world.

A database of compressor information may be used to estimate compressor operation. The database can be used to improve future compressor or refrigeration system design, to improve training of field service technicians, and/or to identify trends related to certain similar environmental conditions. Database server information may also be used for asset management purposes as a tool for analyzing sales and marketing activities. This information can also be shared with system manufacturers or system component manufacturers to aid in the design and implementation of refrigeration systems and system components. In other words, the database may provide compressor operating data related to geographic installation location, compressor type and capacity, and other compressor specification data.

Referring now to FIG. 7, the information stored in the memory system 45 may be used during the management of compressor warranty claims. A manufacturer's warranty may cover the compressor. The warranty may include provisions to replace or repair the compressor. Warranties usually include expiration dates. Additionally, the warranty may include provisions that address compressor misuse and other warranty voiding events. Warranty voiding events may include certain instances of misuse. For example, a warranty may include certain acceptable operating ranges including: refrigerant level range, refrigerant pressure range, refrigerant temperature range, current range, voltage range, ambient temperature range, compressor motor temperature range, Compressor bearing temperature range, and oil temperature data range. If the user ignores the misuse for a period of time and allows the compressor to run without it, the warranty will be voided.

In the event of a compressor failure, a claim can be made under the compressor manufacturer's warranty that the compressor 10 or compressor components are faulty, or be repaired by the manufacturer under the terms of the warranty. In this case, the owner of the compressor can return the compressor 10 to the manufacturer by means of an application indicating the reason for the return. In step 200 the compressor manufacturer may receive warranty claim information.

When the compressor 10 with the memory system 45 is returned to the manufacturer upon a warranty claim, the manufacturer can access the memory system 45 and check the fault history data and operating data. Data from the memory system 45 may be retrieved by the compressor manufacturer in step 202 . By checking the memory system data, the manufacturer can confirm whether the compressor 10 is the cause of the failure. When the refrigeration system data is stored in the memory system 45, the manufacturer can determine that a non-compressor component, such as a condenser or evaporator, is the cause of a failure claimed in a warranty claim. In this case, the manufacturer can immediately determine that the compressor 10 is not faulty or does not require repair. In step 204 the compressor manufacturer may determine whether a non-compressor component is faulty.

Additionally, by examining the contents of memory system 45, the manufacturer can determine whether a warranty void event occurred prior to compressor failure. For example, memory system 45 may reflect that low refrigerant fluid conditions were ignored for a period of time before compressor failure occurred. In this case, the manufacturer may determine that the warranty claim was voided due to the compressor owner ignoring the low refrigerant condition. In step 206 the compressor manufacturer may determine whether a warranty void event has occurred.

When it is determined in step 204 that the compressor 10 is faulty, and when it is determined in step 206 that a warranty void event has not occurred, the compressor manufacturer may repair or replace the compressor in step 208 according to the terms of the warranty. The compressor manufacturer may notify the compressor owner in step 210 when a non-compressor component is faulty, or when it is determined in step 204 or 206 that a warranty void event has occurred.

When the memory system 45 is remotely accessible by the manufacturer through a network device, as described above, the manufacturer can make a preliminary warranty claim determination before the compressor 10 is sent to the manufacturer. For example, before removing the compressor from the system to return it to the manufacturer, the compressor owner may simply notify the manufacturer that it believes a problem covered by the warranty has occurred. The manufacturer may then access the compressor's memory system 45 and examine the memory system data to make an initial determination regarding a warranty claim. When a warranty void event has occurred, the manufacturer may query the compressor owner regarding the occurrence of the warranty void event. The compressor manufacturer is also able to make an initial determination as to whether the complaint is caused by a non-compressor component failure. This initial determination saves time and money previously wasted due to unnecessary or unprotected warranty claims.

During a warranty claim, if it is determined based on the data contained in the memory system 45 that the compressor failure was due to the failure of a non-compressor system component, that data may be shared with the manufacturer of the non-compressor system component. In this way, data and information can be shared with other component and system manufacturers to also aid in the management of their warranty claims.

This description is exemplary only in nature, and various changes are intended to be included within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
