Abstract
An automatic dehumidifier adopting dew-point temperature to control is characterized in that a compressor is connected with a condenser, the condenser is connected with a thermal expansion valve, thethermal expansion valve is connected with an evaporator, the evaporator is connected with the compressor, the external surface of the evaporator is connected with a dew-point temperature transducer, the external surface of the condenser is respectively connected with an air outlet temperature transducer and a fan, a controller is respectively connected with the dew-point transducer, the compressor, the air outlet temperature transducer and the fan. The dehumidifier has the technical effects that the characteristic of high collecting precision of the temperature transducer is utilized, the relative humidity control is transformed into the dew-point temperature control, the relative humidity of fed out air can more precisely satisfy the requirements of users, and the damages of the compressor caused by frequently starting the compressor owing to the lower control precision of existing automatic dehumidifiers which adopt the relative humidity control are avoided.
Description
Technical field
The utility model relates to a kind of automatic type dehumidifier that adopts dew-point temperature to control.
Background technology
At present, the automatic type dehumidifier all adopts the relative humidity of control control return air to come the compression refrigerating system of dehumidifier is controlled, but the precision that the transmitter of relative humidity is gathered is not high, and when environment temperature or humidity change slightly, the relative humidity fluctuation is bigger, the compression refrigerating system perseveration that causes dehumidifier, bigger to the compressor infringement, and cause control accuracy not high.Because the acquisition precision of temperature transmitter is higher than the acquisition precision of humidity transmitter far away,, increased the service life of dehumidifier so it is more accurate to adopt the dew-point temperature control technology that compression refrigerating system is controlled, and has protected compressor widely.
Summary of the invention
The purpose of this utility model has been to provide a kind of automatic type dehumidifier that adopts dew-point temperature to control, it is converted to the comparison dew-point temperature according to the envionmental humidity of user's needs and the leaving air temp that collects, and utilize the actual dew-point temperature of dew-point temperature transmitter collection and compare the start and stop that dew-point temperature is compared and controlled the start and stop of compressor and add unloading and blower fan, make the relative humidity send air more accurately to meet consumers' demand, and the compressor damage that causes of the high frequent start and stop that prevented to cause owing to control accuracy is not high.
The utility model is achieved like this, it comprises controller, compressor, heating power expansion valve, evaporimeter, dew-point temperature transmitter, condenser, leaving air temp transmitter, blower fan, it is characterized in that compressor connects condenser, condenser connects heating power expansion valve, heating power expansion valve connects evaporimeter, evaporimeter connects compressor, evaporator external is connected with the dew-point temperature transmitter, the condenser outer surface is connected with leaving air temp transmitter and blower fan respectively, and controller connects dew-point temperature transmitter, compressor, leaving air temp transmitter and blower fan respectively.
Technique effect of the present utility model is: utilize the high characteristics of temperature transmitter acquisition precision, relative humidity control is converted to dew-point temperature control, make the relative humidity send air more accurately to meet consumers' demand, and prevented to adopt not high and the compressor damage that high frequent start and stop that cause cause of the control accuracy of automatic dehumidifier of relative humidity control in the past.

The specific embodiment
As shown in Figure 1, the utility model is achieved like this, it comprises controller (1), compressor (2), heating power expansion valve (3), evaporimeter (4), dew-point temperature transmitter (5), condenser (6), leaving air temp transmitter (7), blower fan (8), it is characterized in that compressor (2) connects condenser (6), condenser (6) connects heating power expansion valve (3), heating power expansion valve (3) connects evaporimeter (4), evaporimeter (4) connects compressor (2), the evaporimeter next door connects just dew-point temperature transmitter (5), and condenser (6) next door is connected with leaving air temp transmitter (7) and blower fan (8).After cold-producing medium compresses in compressor (2), the refrigerant gas that becomes HTHP is discharged from, by condenser (6), in condenser (6), be condensed into liquid refrigerant, absorb heat by entering evaporimeter (4) after heating power expansion valve (3) throttling then, sucked compressor (2) once more after being evaporated to the gaseous refrigerant of low-temp low-pressure, so circulation.At this moment, blower fan (5) suction air at first cools to dew-point temperature by evaporimeter (4), and airborne water-setting is separated out after becoming liquid state, and cooled air is discharged after heating up through condenser again.Leaving air temp sensor (7) is gathered through the air themperature behind the condenser (6) and is sent it to controller (1), the relative humidity of setting with the user behind controller (1) the collection leaving air temp is converted to the comparison dew-point temperature, compare the start and stop of control compressor (2) and add the start and stop of unloading and blower fan (8) with the actual dew-point temperature that dew point temperature sensor (5) behind the evaporimeter (4) is gathered.
Claims (1)
1, a kind of automatic type dehumidifier that adopts dew-point temperature to control, it comprises controller, compressor, heating power expansion valve, evaporimeter, the dew-point temperature transmitter, condenser, the leaving air temp transmitter, blower fan, it is characterized in that compressor connects condenser, condenser connects heating power expansion valve, heating power expansion valve connects evaporimeter, evaporimeter connects compressor, evaporator external is connected with the dew-point temperature transmitter, the condenser outer surface is connected with leaving air temp transmitter and blower fan respectively, and controller connects the dew-point temperature transmitter respectively, compressor, leaving air temp transmitter and blower fan.
