Refrigeration principle of low temperature constant temperature water tank compressor

The low temperature constant temperature water tank can be called a low temperature circulating water tank. I think everyone should be clear about its use. In the previous article, we have also made a brief introduction to the use, maintenance and repair of the low temperature constant temperature water tank. Today, the author has a low temperature constant temperature water tank. The core part is to share with you.

The core part of the cryogenic constant temperature water tank is nothing more than the refrigeration system. How does the refrigeration system work? The refrigeration system of the low temperature constant temperature water tank consists of four basic parts: the compressor, the condenser, the throttle, and the evaporator. The four large pieces are connected by a copper pipe into a closed system in a certain order. The system is filled with a certain amount of refrigerant. The compressor sucks in the low-temperature and low-pressure Freon gas from the evaporator, and is compressed by the compressor into a high-temperature and high-pressure Freon. The gas (which dissipates heat externally) then flows through the thermal expansion valve (capillary), throttling into a low-temperature, low-pressure Freon gas-liquid two-phase (gas and liquid mixture) object, and the mixture flows into the evaporator at this moment. When it becomes larger, the liquid becomes all gas. In the process of changing, the refrigerant absorbs a large amount of heat, thereby lowering the water temperature in the water tank. At this time, it becomes a low-temperature low-pressure Freon gas, and the low-temperature low-pressure Freon gas is sucked by the compressor. Such compression-----condensation----throttle----evaporation repeated cycles, the refrigerant constantly takes away the heat in the water tank, thereby reducing the temperature of the water, when the water temperature reaches the set value, the compressor stops Work, when the water temperature exceeds the set value, the compressor starts again, so that the cycle is repeated and the temperature is reached.

In fact, this seemingly simple and complicated process has completed the refrigeration process of the liquid in our cryogenic constant temperature water tank. It is also beneficial to know how it works better to maintain it.
