In addition, the air inlet of the condensation radiator 112 is connected with the air outlet of the compressor 122, so that the high-temperature and high-pressure refrigerant gas can directly enter the condensation radiator 112 for cooling, and a complete airflow circulation path is formed. After being cooled in the condensing radiator 112, the refrigerant enters the drying filter 123 through the liquid outlet, so that moisture and impurities in the refrigerant are removed, and the quality of the refrigerant and the stability of a system are ensured. The dried and filtered refrigerant is depressurized through the throttle valve 124 and then enters the inlet of the compressor 122, completing the circulation of the refrigerant. This circulation ensures a stable flow and efficient use of the refrigerant within the system.

Further, the layout of each component of the condensation heat dissipation module 13 is compact, and space is effectively utilized, so that the whole air conditioner is more compact in structure and small in occupied area. The compressor 122 and the dry filter 123 are positioned at the back of the condensing radiator 112, which is convenient to connect and saves space, and improves the integration level of the system. The efficient heat exchange and optimized airflow path make the circulation of refrigerant in the system smoother and more efficient, thus improving the energy efficiency ratio of the whole air conditioner.

In addition, the air inlet 11 and the first air outlet 12 are both disposed on the upper panel 1 and correspond to the condensation heat dissipation module 13, so that cold air required by the condensation heat dissipation module 13 can be directly and effectively introduced, and high-temperature air can be smoothly discharged. The design optimizes the airflow structure and improves the condensing and radiating efficiency.

Further, the split design of the front panel may reduce the effects of noise and vibration generated during operation of the condensing heat rejection module 13 on other modules (e.g., the water circulation module 14 and the control module 119). Which helps to maintain quietness and stability of the air conditioner while it is in operation. The upper panel 1 and the lower panel 2 respectively correspond to different functional modules, and the design ensures that the structure of the front panel is more reasonable and stable.

In particular, in the present embodiment, the plate heat exchanger 113 ensures more rapid and efficient heat transfer between the water side and the refrigerant side with its efficient heat exchange performance, and its unique corrugated plate design allows for a greatly improved heat exchange efficiency with little heat loss. Under the condition of the same pressure loss, the heat transfer coefficient of the plate heat exchanger 113 is 3-5 times higher than that of the traditional tubular heat exchanger, and the energy efficiency ratio of the whole air conditioning system is improved.

In addition, by the design of the four-way reversing valve 118, the flexible switching of the refrigerating and heating functions in the water circulation module 14 is realized.

In this embodiment, the components of the water circulation module 14 are connected in a specific manner to form an independent module, and this modular design makes maintenance of the system more convenient and quick, and a certain component can be replaced or maintained independently without affecting the operation of the whole system.

Optionally, as shown in fig. 8 to 10, the water circulation module 14 further includes a pressure regulating tank 117, and the pressure regulating tank 117 is connected to the liquid supply pipe. The pressure regulating tank 117 is provided to regulate fluctuation of water supply pressure in the water circulation module 14, effectively stabilize water supply pressure, and ensure stability and uniformity of water flow.

Optionally, as shown in fig. 8 to 10, the water circulation module 14 further includes a surface cooler 125, a three-way valve 126 and a proportional control valve 127, the condensation heat dissipation module 13 includes a condensation heat sink 112, the surface cooler 125 is located right behind the condensation heat sink 112, and a liquid inlet and a liquid outlet of the surface cooler 125 and a liquid inlet and a liquid outlet of the plate heat exchanger 113 are arranged in parallel through the three-way valve 126 and the proportional control valve 127.

Specifically, in the present embodiment, the surface cooler 125 and the plate heat exchanger 113 are arranged in parallel by the three-way valve 126 and the proportional control valve 127, so that the system can flexibly adjust the cooling or heating mode as needed. By adjusting the opening degree of the proportional control valve 127, the distribution of the water flow between the surface cooler 125 and the plate heat exchanger 113 can be precisely controlled, thereby realizing the rapid switching and precise control of the cooling or heating function.

In the cooling mode, the surface cooler 125 can directly cool water by using the heat of the condensing radiator 112 without performing secondary heat exchange through the plate heat exchanger 113, so that heat loss can be reduced and the energy efficiency ratio can be improved. In the heating mode, the heat of the plate heat exchanger 113 can be fully utilized to heat water by adjusting the three-way valve 126 and the proportional control valve 127, and the energy efficiency is also improved.

In addition, the surface cooler 125 is located right behind the condensation radiator 112, so that heat discharged by the condensation radiator 112 can be fully utilized, heat accumulation in the system is avoided, and the stability of the system is improved. Meanwhile, the design of parallel arrangement enables the system to have better redundancy, and even if one component fails, the normal operation of the system can be maintained by adjusting the other components. The design of flexibly adjusting the refrigerating/heating mode and improving the energy efficiency ratio enables the system to more efficiently utilize energy and reduce energy consumption. Meanwhile, the influence on the environment can be reduced by optimizing the heat exchange and heat recovery processes of the system, and the energy-saving and environment-friendly requirements are met.

Alternatively, as shown in fig. 8-10, both the surface cooler 125 and the condensing radiator 112 employ parallel flow microchannel radiators.

Specifically, the parallel flow micro-channel radiator is designed by a unique micro-channel, so that the radiating area is greatly increased, and the radiating capacity of the radiator is obviously improved under the same volume. And compared with the traditional radiator, the parallel flow micro-channel radiator can provide higher heat radiation efficiency under the same condition, so that the surface cooler 125 and the condensing radiator 112 can radiate heat more quickly and effectively, thereby ensuring the stable operation of the system.

In addition, since the micro-channel radiator is very small, the structure can be compact while maintaining efficient heat dissipation, so that the surface cooler 125 and the condensing radiator 112 are more space-saving, and have an important effect on the lightening and thinning of the air conditioner.

Alternatively, as shown in fig. 8 to 10, the circulating water pump 116 is an electronic canned pump. Compared with the traditional horizontal industrial centrifugal pump, the space occupation is reduced by 60 percent, the weight is reduced by 70 percent, and the space inside the air conditioner is further saved.

According to a second aspect of the present utility model, there is provided an energy storage device comprising a battery module and the cooling structure of the first aspect, the battery module being located inside the frame 3, and an air conditioner being capable of cooling the battery module.

Specifically, due to the cooling structure provided in the first aspect of the present utility model, an independent air conditioner is provided, and the air conditioner is provided at a vacant position between the two connection posts 31 of the frame, the occupied space inside the frame 3 is saved, the arrangement space of the battery module is increased, and the energy density of the battery is improved.
