Description

Technical Field

[0001] The present application relates to the technical field of air conditioners, and in particular to an energy storage air conditioner. Background Art

[0002] The core technology of energy storage air conditioners lies in their energy storage function. This air conditioning system achieves the goal of energy saving and emission reduction by storing electricity during off-peak hours and then using the stored energy for cooling during peak hours. During off-peak hours, energy storage air conditioners use cheap electricity to store energy and then release it during peak hours, thereby reducing the load on the power grid during peak hours, reducing energy waste, and also reducing pollution to the environment. In addition, energy storage air conditioners can also improve energy utilization efficiency, balance the load on the power grid, improve the stability and reliability of the power grid, and provide users with more stable and reliable power supply services.

[0003] There are two types of energy storage air conditioning products on the market: air cooling and liquid cooling. Liquid cooling has gradually become the main means of energy storage temperature control. Most liquid cooling temperature control products are currently large and heavy, making them difficult to repair, replace and move. The large size leads to high costs and large floor space, which squeezes the space for energy storage batteries. At the same time, energy storage temperature control products on the market have high energy consumption and low energy efficiency. While dissipating heat for the battery, they also consume a lot of electricity, which is not in line with the current development trend of low-carbon energy conservation.

[0004] Most of the current energy storage liquid cooling technologies do not have a fire protection system, and the energy storage system needs to be equipped with a fire protection system to meet the fire protection function. In addition, the heat dissipation of the electronic control drive is usually in the form of air cooling. In a high temperature environment, the ambient temperature is high, and air cooling cannot meet the heat dissipation requirements of high-power energy storage temperature control products.

[0058] In this application, the energy storage air conditioner includes a compressor, a condenser, a pressure relief valve, a heat exchanger, and a control system: the compressor is one of the core components of the energy storage air conditioning system, and is mainly responsible for compressing the refrigerant from a low temperature and low pressure state to a high temperature and high pressure state.

[0065] The fire fighting system 130 is connected and communicated with the water flow, and the fire fighting system 130 is used to extinguish the fire when the energy storage air conditioner catches fire.

[0066] When the four-way valve 200 is in the first state, the compressor 100 outputs the refrigerant to the condenser 300, and the condenser 300 dissipates the heat of the refrigerant and outputs it to the plate heat exchanger 600. The plate heat exchanger 600 exchanges heat between the cooled refrigerant and the water flow in the water circuit 700 to reduce the temperature of the water. The low-temperature water in the water circuit 700 cools the energy storage device.

[0067] When the four-way valve 200 is in the second state, the compressor 100 outputs the refrigerant to the plate heat exchanger 600. The high-temperature refrigerant exchanges heat with the water in the water circuit 700 in the plate heat exchanger 600 to increase the temperature of the water. The high-temperature water in the water circuit 700 heats the energy storage device.

[0068] Through the above solution, the energy storage air conditioning system can switch between cooling and heating modes according to the needs of the energy storage device by adjusting the state of the four-way valve 200, so that the energy storage device can be adjusted by the energy storage air conditioning under different temperature conditions.

[0073] The compressor 100 outputs the refrigerant to the condenser 300 through the second interface and the first interface in sequence. The condenser 300 dissipates the heat of the refrigerant and outputs it to the plate heat exchanger 600. The plate heat exchanger 600 exchanges heat with the water flow in the water circuit 700 to reduce the temperature of the water. The low-temperature water in the water circuit 700 cools the energy storage device. The refrigerant passing through the plate heat exchanger 600 flows back to the compressor 100 through the third interface and the fourth interface.

The refrigerant passing through the direct cooling plate 160 flows back to the compressor 100 through the first interface and the fourth interface.

[0114] In some embodiments, one end of the condenser 300 is connected to the four-way valve 200, and the other end is connected to the pressure relief valve 400. The pressure relief valve 400 releases the pressure of the refrigerant after the heat is dissipated by the condenser 300 to gasify the refrigerant, which can quickly cool the refrigerant.

[0115] In some embodiments, the energy storage air conditioner further includes an electric control board, which is electrically connected to the compressor 100. The start and stop of the compressor 100 and the operating frequency of the compressor 100 can be controlled by the electric control board.

[0116] In some embodiments, the pipeline is connected to a heat sink 500, and the heat sink 500 is attached to the electronic control board.

[0117] In some embodiments, the heat sink 500 is disposed between the condenser 300 and the direct cooling plate 160 , and the refrigerant cooled by the condenser 300 enters the heat sink 500 , and the heat sink 500 cools the electric control board.

[0118] In some embodiments, the heat dissipation plate 500 is disposed between the pressure relief valve 400 and the direct cooling plate 160 .

[0119] The heat sink 500 can effectively reduce the temperature of the electric control board and ensure that the electric control board operates at a suitable temperature. This design improves the stability and reliability of the electric control board and prolongs its service life.

[0120] In some embodiments, a fan 310 is provided at the condenser 300, and the fan 310 is used to drive airflow through the condenser 300. The fan 310 can accelerate the heat dissipation process of the condenser 300 and improve the condensation efficiency. This design enables the energy storage air conditioning system to maintain efficient operation even in a high temperature environment.
