Description

Technical Field

[0001] This utility model relates to the field of air conditioning refrigerant replenishment system technology, and in particular to a differential pressure driven refrigerant replenishment system. Background Technology

[0002] Electronic devices are consuming increasingly more power and generating more heat. However, if they are kept at high temperatures for extended periods, their efficiency and accuracy will decrease. Therefore, air conditioning is generally needed to cool them down.

[0003] Air conditioning equipment uses its built-in refrigerant for cooling. When running for extended periods, refrigerant consumption is significant, and the cooling effect of the air conditioning unit will be greatly reduced. Therefore, it is necessary to replenish the refrigerant inside the air conditioning unit. Currently, refrigerant is generally replenished manually, but this has the following drawbacks: 1. It requires manual replacement, increasing labor costs. 2. Before manually replenishing the refrigerant, the air conditioning unit needs to be powered off and disassembled, which is a cumbersome procedure and can affect the normal operation of electronic equipment, reducing productivity. 3. It is difficult to control the amount of refrigerant used manually; too much or too little will affect the cooling efficiency of the air conditioning unit. Utility Model Content

[0031] In an optional implementation of this embodiment, the replenishment tank 3 is provided with a constant pressure gas storage chamber pressure gauge 33, which is used to detect the amount of liquid replenishment liquid in the liquid storage chamber 32 of the replenishment tank 3.

[0032] Specifically, when the pressure value detected by the pressure gauge 33 of the constant pressure storage chamber reaches the static pressure of the return water pipe 1, it means that the liquid in the liquid storage chamber 32 of the replenishment tank 3 is used up, the pressure of the air storage chamber 31 is higher than the pressure of the liquid storage chamber 32, and the pressure of the liquid storage chamber 32 is higher than the static pressure of the return water pipe 1.

[0039] Working principle: The system consisting of a return water pipe, a plate heat exchanger, and an outlet water pipe is a closed water system with a stable static pressure. The replenishment tank is connected to the return water pipe through a replenishment pipe. The gas storage chamber inside the replenishment tank also has a static pressure. When the static pressure in the gas storage chamber is greater than the static pressure in the return water pipe as determined by the pressure gauge of the set constant pressure gas storage chamber, a pressure difference exists. The liquid replenishment in the liquid storage chamber is then pumped out through this pressure difference and replenished to the return water pipe through the replenishment pipe, a one-way valve, and an electric replenishment valve.

[0040] When fluid replenishment is required, the electric fluid replenishment valve is opened; when fluid replenishment is not required, the electric fluid replenishment valve is closed.

[0041] By controlling the air filling valve to fill the air storage chamber of the replenishment tank, the replenishment speed is controlled. The greater the static pressure in the air storage chamber, the greater the pressure difference between it and the static pressure in the return water pipe, and the faster the replenishment speed.

[0042] In summary, this utility model embodiment proposes a differential pressure driven liquid replenishment system, including a return water pipe, a plate heat exchanger, an outlet water pipe, and a liquid replenishment tank installed on the return water pipe. The liquid replenishment tank is provided with an air storage chamber and a liquid storage chamber. Air is injected into the air storage chamber through an air filling valve located at the top of the liquid replenishment tank. Utilizing the pressure difference between the replenishment liquid in the liquid storage chamber of the liquid replenishment tank and the water in the return water pipe, the replenishment liquid is replenished into the return water pipe. No manual liquid replenishment operation is required, effectively eliminating interference from other factors, reducing costs, and improving the liquid replenishment efficiency of the liquid replenishment system.
