Description

Water-cooled split room air conditioner

The utility model belongs to an air conditioner, in particular to a household split type room air conditioner.

At present, household air conditioners used in the prior art are mainly air-cooled room air conditioners, including window air conditioners and split air conditioners. There are two types of split air conditioners: one outdoor unit to one indoor unit and one outdoor unit to several indoor units. The feature of this household room air conditioner is to use outdoor air to cool the condenser of the air conditioner, so as to achieve the purpose of discharging the heat of the room to the outside. The advantages of air-cooled room air conditioners are that users can install or remove them independently, can be individually controlled, billed independently, and do not require a centralized cold source room. But its disadvantage is that the condenser must be placed on the outdoor side of the outer wall, and a fan is used to ventilate and dissipate heat (the difference between a split air conditioner and a window air conditioner is that the compressor and condenser of the former are placed outdoors). Its main disadvantages are: a. Since the exterior walls of general residential buildings have exterior windows, the heat exhausted by the condenser will cause thermal pollution to the surrounding environment of the building, and affect the outdoor thermal environment of the windows in the adjacent room above the condenser. Once the air conditioner is turned on downstairs, opening the windows upstairs may introduce the heat exhausted downstairs. b. The condenser or outdoor unit placed on the outer wall affects the appearance of the building facade and brings great constraints to the architectural design. c. The cooling energy efficiency ratio COP of the air-cooled method is lower than that of the water-cooled method. Generally, the former is below 3, and the latter is 4-5. Moreover, for high-rise residential buildings, due to the effect of natural convection, the external ambient temperature of the outdoor unit of the upper residential building is much higher than that of the lower outdoor unit, the COP will be greatly reduced, the energy consumption will increase, and the cooling capacity will also be significantly reduced. d. Since the distance between the indoor unit and the outdoor unit cannot be too long, the installation position of the indoor unit is greatly restricted by the position of the outdoor unit, resulting in poor airflow organization. For the "one-to-several" split units, some indoor units may not be installed in proper positions.

For commercial buildings such as hotel guest rooms and offices in office buildings, fan coil units are usually used in the prior art, and water-cooled chillers are used as cold sources. The advantage of this system is that there are no outdoor units and air-cooled condensers that affect the appearance, no damage to the external thermal environment of the building, high energy efficiency ratio of the refrigeration system, and no restrictions on the installation position of the fan coil unit. But this method is not completely applicable to ordinary residential buildings. This is because: on the one hand, the centralized cold source needs to occupy a large space in the computer room; the control of the chilled water system is complicated, which is not convenient for household billing, which brings troubles to property management; on the other hand, since the energy consumption is mainly in the centralized cold source, During part load periods, if only a few occupants require air conditioning, the central cooling source still needs to be running and is therefore less efficient.

In view of the deficiencies and defects of the prior art, one of the purposes of this utility model is to provide a water-cooled split room air conditioner in order to adapt to the characteristics of high-rise and high-density residential buildings in the 21st century. The air conditioner does not damage the appearance of the building facade and the thermal environment outside the building wall, but also has a high energy efficiency ratio, is energy-saving and economical.

Another purpose of the utility model is to enable residents to freely adjust and control, without difficulty in energy consumption and billing, and easy to use.

The utility model is realized through the following technical solutions: it is mainly composed of a compressor, a condenser, one or more direct evaporative coils installed in an air-conditioned room, and refrigerant pipes connecting the coils with the compressor and the condenser It is characterized in that the condenser adopts a water-cooled condenser, and the compressor and the water-cooled condenser are packaged in a shock-absorbing and noise-absorbing chassis to form a water-cooled condensing unit. The water-cooled condensing unit It is connected with the cooling water system through the cooling water inlet and outlet pipes.

Accompanying drawing 1 is the structural representation of the utility model.

Accompanying drawing 2 is the installation example of installing water-cooled split air conditioner (one drags four) for one living room and three bedroom households. The letter D in the figure represents the bedroom, L represents the living room, T represents the bathroom, K represents the kitchen, and V represents the balcony.

The working principle, specific structure and best implementation mode of the present utility model will be described in detail below in conjunction with the accompanying drawings.

The water-cooled split room air conditioner consists of a water-cooled compression condensing unit A plus one or several direct evaporative coils B. The compression condensing unit mainly includes a water-cooled condenser 1, a compressor 2, a throttling device 3, and a vibration-reducing and noise-reducing chassis 4. The water-cooled condenser is connected to the cooling water system by the cooling water inlet pipe 5 and the water outlet pipe 6 . The compression condensing unit can be placed in the ceiling of the bathroom, kitchen, hallway, etc. The direct evaporative coil includes a direct evaporator 7, a fan 8, a case 9, and the like. Direct evaporative coils are installed in air-conditioned rooms, and can have various forms such as wall-mounted and vertical. The direct evaporative coil is connected with the compression condensing unit through the refrigerant pipeline 10 . Air conditioners with multiple direct evaporative coils can use variable frequency, variable refrigerant flow (VRV) control.

In terms of architectural design, the water-cooled split room air conditioner does not require the location of the outdoor unit, but requires the entire building to have a unified centralized cooling water system, or the user has an independent cooling water system.

Compared with the prior art, the utility model has the following advantages and beneficial effects: the water-cooled split room air conditioner can replace the existing air-cooled room air conditioner (window type and split type) for air conditioning in high-rise residences. It not only has the advantages of convenient individual control of existing air-cooled room air conditioners, independent billing, independent installation or removal, and no need for a centralized cold source machine room, but also does not damage the beauty of the building facade; does not damage the external heat of the building. Environment; high COP, low energy consumption. Since the air conditioner encapsulates the compressor and the water-cooled condenser in a shock-absorbing and noise-absorbing case, it does not need to be open to the air, so the noise is small. For a multi-room apartment, you can choose to place a compression condensing unit on the ceiling of the bathroom, kitchen, storage room, hallway or aisle that is relatively close to the center of the unit, so that you can easily connect multiple direct evaporator coils to the living room and bedroom. , to achieve the purpose of controlling multiple rooms with one host, without being limited by the location of the outer wall.
