Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioning unit and a cooling system. Background Art

[0002] like Figure 1 and Figure 2 As shown, the current traditional air-cooled air conditioner is generally composed of an indoor main unit 1 and an outdoor unit 2. The heat absorbed by the indoor main unit 1 on the indoor side is exchanged with the outside through the condenser of the outdoor unit 2, thereby reducing the indoor temperature. However, the outdoor unit needs to be placed outdoors, which requires a certain amount of space and maintenance, and the overall cost is relatively high, especially when there are multiple condensers and the installation area is insufficient. Utility Model Content

[0003] The utility model discloses an air conditioning unit and a cooling system, which have simple structure, high efficiency and energy saving, and replace an outdoor condenser by plate heat exchange, thus saving the purchase of condensers and the space occupied.

[0004] In order to achieve the above object, the utility model provides the following technical solutions:

[0005] In a first aspect, the utility model provides an air conditioning unit, comprising: a host module; the host module comprises a shell and a refrigeration device group arranged in the shell;

[0006] The refrigeration device group includes a compressor, a plate exchanger, a liquid storage tank, a fluorine pump and an evaporator;

[0007] The plate exchanger comprises a first heat exchange channel and a second heat exchange channel, wherein the first heat exchange channel is used to connect to an external cold source; the second heat exchange channel is sequentially connected in series with the liquid storage tank, the fluorine pump, the evaporator and the compressor to form a circulation loop;

[0008] A first parallel branch is also connected between the outlet of the evaporator and the inlet of the second heat exchange channel, the first parallel branch is connected in parallel with the compressor, and a first control valve is provided on the first parallel branch;

[0009] Two ends of the fluorine pump are connected in parallel with a second parallel branch, and a second control valve is arranged on the second parallel branch.

[0010] In the above-mentioned air-conditioning unit, the plate exchanger is used to replace the condenser, and the plate exchanger is arranged in the host module, so that the entire air-conditioning unit has a compact structure, saves the purchase of the condenser and the floor space, and has a great cost advantage. In particular, when there are multiple plate exchanges, the external cold source can be supplied by the same cooling module such as a cooling tower, and the floor space is greatly reduced. When the above-mentioned air-conditioning unit is used, when the outdoor temperature is high, such as in summer, the air-conditioning unit operates in the compressor mode, that is, the compressor is turned on, and the first control valve on the first parallel branch is closed at the same time; the second control valve on the second parallel branch is opened, and the fluorine pump is turned off at the same time.

When the air-conditioning unit operates in the compressor mode, the plate exchanger is used to perform condensation heat exchange with the external cold source such as water, and the condensation temperature is lower, which is more energy-efficient than air cooling. And compared with the use of air condensers to connect longer copper pipes, the engineering cost of copper pipes is reduced, and the energy efficiency attenuation caused by long connecting pipes is also avoided. When the air conditioning unit operates in the fluorine pump mode, the plate heat exchanger performs condensation heat exchange with a low-temperature external cold source such as water, and the use of natural cold sources has higher energy efficiency.

[0042] like Figures 3 to 6 As shown, an embodiment of the utility model provides an air-conditioning unit, including: a host module 100; the host module 100 includes a shell 110 and a refrigeration device group arranged in the shell 110; the refrigeration device group includes a compressor 120, a plate exchanger 130, a liquid storage tank 140, a fluorine pump 150 and an evaporator 160; the plate exchanger 130 includes a first heat exchange channel 131 and a second heat exchange channel 132, and the first heat exchange channel 131 is used to connect to an external cold source; the second heat exchange channel 132 is connected in series with the liquid storage tank 140, the fluorine pump 150, the evaporator 160 and the compressor 120 to form a circulation loop; a first parallel branch is also connected between the outlet of the evaporator 160 and the inlet of the second heat exchange channel 132, the first parallel branch is connected in parallel with the compressor 120, and a first control valve 181 is arranged on the first parallel branch; the two ends of the fluorine pump 150 are connected in parallel with a second parallel branch, and a second control valve 182 is arranged on the second parallel branch.

[0043] One possible way to achieve this is as follows: Figure 3 As shown, the plate exchanger 130 has a first heat exchange channel 131 and a second heat exchange channel 132. Chilled water can flow into the first heat exchange channel 131.

A one-way valve is also provided on the pipeline between the compressor 120 and the plate exchanger 130, and the one-way valve is located between the connection between the first parallel branch and the circulation circuit and the compressor 120.

[0044] In the above-mentioned air-conditioning unit, the plate exchanger 130 is used to replace the condenser, and the plate exchanger 130 is arranged in the host module 100, so that the entire air-conditioning unit has a compact structure, saves the purchase of the condenser and the floor space, and has a great cost advantage. In particular, when there are multiple plate exchangers, the external cold source can be supplied by the same cooling module such as a cooling tower, and the floor space is greatly reduced.

When the air-conditioning unit operates in the compressor mode, condensation heat exchange is performed with the external cold source such as water through the plate exchanger, and the condensation temperature is lower, which is more energy-efficient than air cooling. And compared with the use of air condensers to connect longer copper pipes, the engineering cost of copper pipes is reduced, and the energy efficiency attenuation caused by long connecting pipes is also avoided. When the air-conditioning unit operates in the fluorine pump mode, condensation heat exchange is performed with a low-temperature external cold source such as water through a plate exchanger, and the use of a natural cold source is more energy efficient. The first control valve 181 and the second control valve 182 can be a one-way valve, and the flow direction of the first control valve is from the evaporator to the plate exchanger, and the flow direction of the second control valve is from the liquid storage tank to the evaporator, so that the air-conditioning unit can be dynamically adjusted according to the actual outdoor temperature to achieve energy-saving effects.
