The working principle of the industrial chiller is mainly based on vapor compression refrigeration technology. The liquid refrigerant vaporizes and absorbs heat in the evaporator to achieve the cooling effect.
Specifically, the working process of an industrial chiller can be divided into four main parts: compression, condensation, expansion and evaporation. First, the compressor compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas. These gases are then cooled by cooling water or air in the condenser and turned into a high-temperature and high-pressure liquid. Next, the liquid refrigerant enters the evaporator through the expansion valve. Due to the sudden drop in pressure, the liquid refrigerant quickly evaporates into a low-temperature and low-pressure gas. At the same time, it absorbs a large amount of heat, causing the water temperature in the chiller to drop. Finally, the low-temperature and low-pressure refrigerant gas enters the compressor again to start a new cycle.
In this process, the heat absorbed by the refrigerant in the evaporator is transferred to the equipment that needs cooling through the cooling water system of the chiller, thereby achieving the cooling effect. At the same time, the industrial chiller is also equipped with a corresponding control system that can automatically adjust the flow and temperature of the refrigerant as needed to maintain a constant cooling effect.
In addition, industrial chillers usually adopt some energy-saving technologies, such as heat recovery technology, intelligent control technology, etc., to improve energy efficiency and reduce operating costs. Heat recovery technology can recycle the heat discharged from the condenser for heating or other purposes; intelligent control technology can automatically adjust the operating status of the chiller based on actual operating conditions to achieve the best energy efficiency ratio.
In short, the working principle of the industrial chiller is to achieve the cooling effect through the phase changes of the refrigerant during compression, condensation, expansion and evaporation. It is also equipped with corresponding control systems and energy-saving technologies to improve energy efficiency and reduce operating costs.
