Industrial Water Chiller Manufacturers in Bihar Working Principle of Water Chillers The working principle of a water chiller revolves around the refrigeration cycle. This cycle involves four main stages: compression, condensation, expansion, and evaporation. First, the compressor increases the pressure of the refrigerant gas, causing it to heat up. Next, the refrigerant is cooled down in the condenser and changes into a liquid state. This liquid refrigerant then passes through an expansion valve, where its pressure is reduced, leading to cooling. Finally, the refrigerant absorbs heat in the evaporator and circulates back to the compressor to start the cycle again. Key Components of a Water Chiller Industrial water chillers are composed of several crucial components, including the compressor, evaporator, condenser, expansion valve, and refrigerant. The compressor is the heart of the system, responsible for circulating the refrigerant through the cycle. The evaporator absorbs the heat from the process or equipment that requires cooling, while the condenser releases the absorbed heat. The expansion valve regulates the flow of refrigerant into the evaporator, ensuring efficient operation. The refrigerant is the fluid that absorbs and releases heat, facilitating the cooling process.
