The refrigeration cycle process of the water dispenser is realized through compression cycle refrigeration technology. This process involves the continuous circulation of refrigerant between the evaporator, compressor, condenser and expansion valve to achieve cooling of the water.
The first step in the refrigeration cycle is the evaporation process in the evaporator. When the user selects cold water, the water passes through the heat exchange tube of the evaporator and exchanges heat with the refrigerant. The heat of the water is absorbed, causing the water temperature to drop rapidly, and the refrigerant changes from liquid to gas.
The gaseous refrigerant is sucked into the compressor, which is the power source in the entire refrigeration system. In the compressor, the refrigerant is compressed into a high-temperature and high-pressure gas. This process requires a certain amount of electrical energy.
The high-temperature and high-pressure gas refrigerant passes through the condenser and comes into contact with external air or cooling medium. During this process, the refrigerant releases heat, cools and condenses into a liquid state, while the heat of the external environment is also taken away.
The condensed liquid refrigerant passes through the expansion valve, and the pressure decreases rapidly, causing it to transform into a low-temperature and low-pressure state, ready to re-enter the evaporator.
Through this series of processes, the refrigerant completes a complete cycle. The refrigerant absorbs the heat of the water in the evaporator, causing the water temperature to drop, and then is compressed into a high-temperature and high-pressure gas in the compressor. It releases heat in the condenser and condenses into a liquid. Finally, it is decompressed through the expansion valve and re-enters the evaporator. device.
Summary of working principle:
The working principle of the refrigeration cycle is based on the basic principles of thermodynamics, that is, under different temperature and pressure conditions, the refrigerant undergoes phase change between liquid and gaseous states, and through this process, the water is cooled. The function of the compressor and expansion valve is to maintain the circulation of refrigerant in the system and ensure that the entire refrigeration system can operate stably and efficiently.
