Refrigerant is a working substance that is continuously cyclically changed in a refrigeration system to achieve refrigeration, also called a working fluid. The refrigerant is vaporized in the evaporator to absorb the heat of the cold object and is cooled, and the heat is released into the surroundin

Refrigerant, also known as refrigerant, refrigerant, and snow, is a medium used in various heat engines to complete energy conversion.These materials typically increase power with a reversible phase change, such as gas-liquid phase change. Such as steam in steam engines, snow in refrigerators, and s

1. Working principle of gas cylinder pressure reducing valve:The high pressure chamber of the gas cylinder pressure reducing valve is connected to the cylinder, and the low pressure chamber is a gas outlet and leads to the use system. The indication of the high pressure gauge is the pressure of the
