Description

Technical Field

[0001] The utility model relates to the technical field of vertical energy storage air conditioners, and more specifically, to a battery pack dehumidification module of a vertical energy storage air conditioner. Background Art

[0002] The working principle of the vertical energy storage air conditioner is to use an external power source or solar panel with lower electricity price at night to store electricity in the energy storage battery pack at midnight or other low load times. In this way, the pre-stored electricity can be used to operate the air conditioner during high load during the day, thereby reducing dependence on external power sources and effectively saving electricity costs. In the use of existing vertical energy storage air conditioners, semiconductor refrigeration dehumidifiers are usually placed in the warehouse to dehumidify the battery pack. Due to the limitation of the refrigeration capacity of the semiconductor refrigeration system, the dehumidification efficiency is relatively low, which is not conducive to the timely dehumidification of the environment around the battery pack, resulting in a greater risk of moisture in the battery pack in the vertical energy storage air conditioner, affecting the service life of the battery pack. In view of this, we propose a battery pack dehumidification module for a vertical energy storage air conditioner to solve the above problems. Utility Model Content

The refrigerant inlet pipe 5 and the refrigerant return pipe 6 both pass through the dehumidification shell 2 and extend to the outside. The refrigerant inlet pipe 5 and the refrigerant return pipe 6 can be connected to the refrigerant pipeline in the vertical energy storage air conditioner 1, so that the low-temperature and low-pressure gas-liquid mixed refrigerant in the refrigerant pipeline enters the heat-conducting bent pipe 401 through the refrigerant inlet pipe 5, and the low-temperature and low-pressure gas-liquid mixed refrigerant in the heat-conducting bent pipe 401 returns to the refrigerant pipeline through the refrigerant return pipe 6, thereby maintaining the low-temperature and low-pressure gas-liquid mixed refrigerant circulation effect in the refrigerant pipeline.

[0021] Among them, Figure 2 As shown, the outside of the dehumidification shell 2 is fixedly connected to an air inlet pipe 202, and one end of the air inlet pipe 202 is fixedly connected to an air hood 203. The centrifugal fan 3 can be used to draw the humid air around the battery pack 101 into the dehumidification shell 2 through the air inlet pipe 202. The low-temperature and low-pressure gas-liquid mixed refrigerant in the heat-conducting bent pipe 401 keeps the cooling fins 402 in a low-temperature state.

[0022] Among them, Figure 2 As shown, the bottom side of the dehumidification shell 2 is fixedly connected with a water outlet pipe 204, which can be connected to the drainage pipeline of the vertical energy storage air conditioner 1, so that the water in the dehumidification shell 2 can flow into the drainage pipeline of the vertical energy storage air conditioner 1 through the water outlet pipe 204 and finally be discharged to the outside.

The centrifugal fan 3 is used to draw the humid air around the battery pack 101 into the dehumidification shell 2 through the air inlet pipe 202. The low-temperature and low-pressure gas-liquid mixed refrigerant in the heat transfer bend 401 makes the cooling fins 402 in a low-temperature state. The cooling fins 402 in the tube-fin evaporator 4 are used to quickly exchange heat with the passing humid air, thereby cooling the humid air and precipitating moisture to form low-temperature dry air. The centrifugal fan 3 finally discharges the low-temperature dry air through the air outlet pipe 301, so that the environment around the battery pack 101 can be efficiently dehumidified, and the humidity requirements of the environment around the battery pack 101 can be effectively and timely guaranteed.
