Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage industrial air conditioners, and in particular relates to an exhaust expansion water tank of an energy storage industrial air conditioner. Background Art

[0002] In energy storage industrial air conditioners, the water cooling system can exchange and cool the heat generated by the operation of customer terminal equipment to ensure the normal operation of the customer equipment system. In the water cooling system of existing energy storage industrial air conditioners, the system pressure stabilization mainly relies on the expansion tank, and its exhaust mainly relies on the exhaust valve arranged at a high position.

[0003] However, due to the limited space size of products on the market, many exhaust valves cannot be placed at the highest point, which results in a sharp increase in exhaust time cost and poor exhaust effect during actual use.

[0004] Moreover, for expansion tanks that are compatible with extreme high and low temperatures, the market selection is narrow and the development cost is high. In addition, extreme high and low temperatures can easily cause large fluctuations in system pressure. After long-term and large expansion and contraction, the rubber matrix inside the expansion tank has a sharp decline in service life and is prone to damage, which can cause leakage and cause serious losses to equipment operation. Moreover, the expansion tank needs to maintain air pressure through regular maintenance and gas replenishment to ensure normal system pressure. Utility Model Content

[0005] In order to overcome the defects of the prior art, the utility model provides an exhaust expansion water tank for an energy storage industrial air conditioner, which can be compatible with the situation where the coolant pressure fluctuates greatly under extremely high and low temperatures.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] An exhaust expansion water tank for an energy storage industrial air conditioner, comprising:

[0008] A water tank, in which coolant is injected, and a liquid inlet of the water tank is connected to the customer terminal equipment;

[0009] A water pump, one end of which is connected to the liquid outlet of the water tank, and the other end of which is connected to the heat exchange channel of the customer terminal device;

[0010] Automatic exhaust valve, which is fixedly connected to the outside of the water tank;

[0011] An air guide pipe, the upper end of which is communicated with the automatic exhaust valve, the lower end of which extends downward into the water tank, and the lower end of which is not lower than the coolant.

[0012] The beneficial effects of adopting the above technical solution are as follows: the exhaust expansion water tank of the energy storage industrial air conditioner continues to use the advantages of the degassing tank to quickly realize the stripping of gas in the coolant, and removes excess gas in the system through the air duct to avoid cavitation of the water pump and avoid reduction in hydraulic performance; because the air above the lower end of the air duct cannot be discharged, that is, there is air in the water tank at extremely high and low temperatures to balance the pressure of the coolant after thermal expansion and contraction, so as to stabilize the pressure of the coolant.

[0013] In one embodiment, the liquid outlet of the water tank is arranged at the lower part of the water tank.

[0014] The beneficial effect of adopting the above technical solution is that the liquid outlet of the water tank is arranged at the lower part of the water tank, which is conducive to discharging the coolant in the water tank.

[0015] In one embodiment, a liquid level line is provided on the water tank, and the liquid level line is flush with the lower end of the air guide tube.

[0016] The beneficial effect of adopting the above technical solution is that the liquid level line can be used as a reference for the injection of coolant to avoid excessive or insufficient injection of coolant.

[0017] In one embodiment, the liquid inlet of the water tank is below the liquid level line.

[0018] In one embodiment, the air guide pipe is vertically arranged on the water tank.

[0019] The beneficial effect of adopting the above technical solution is that the vertical height of the part of the air guide pipe extending into the water tank directly determines the gas storage capacity and indirectly determines the pressure stabilization range.

[0020] In one embodiment, the cross-section of the water tank is square or circular.

[0021] In one embodiment, the air guide tube is fixedly connected to the water tank.

[0022] The beneficial effects of the utility model are:

[0023] The exhaust expansion water tank of this energy storage industrial air conditioner adopts the advantages of the degassing tank to quickly strip the gas in the coolant and remove the excess gas in the system through the air duct to avoid cavitation of the water pump and reduce the hydraulic performance. Since the air above the lower end of the air duct cannot be discharged, that is, at extremely high and low temperatures, there is air in the water tank to balance the pressure of the coolant after thermal expansion and contraction, so as to stabilize the pressure of the coolant.
