What is the Working Principle of the Chiller?

The basic working principle of the industrial chiller is that the vapor is refrigerated by compression, that is, the principle analysis of the heat absorption when different liquid refrigerants vaporize and the heat release when the vapor condenses is used to study refrigeration.

In refrigeration technology, evaporation is the process by which a liquid refrigerant turns into a gaseous state when it reaches a boil. The liquid entering the gas must absorb heat from the outside world, so this is an endothermic process. The temperature at which the liquid refrigerant evaporates is called the evaporation temperature, and condensation refers to the cooling of the vapor to a temperature equal to or lower than saturation, which can convert the vapor into a liquid.

Industrial chillers can provide constant temperature, constant flow and constant pressure cooling water. During the operation of the industrial chiller, a certain amount of water is first injected into the water tank inside the machine, and the water is cooled by the chiller refrigeration system, and then the low-temperature cooling water is injected into the equipment to be cooled by the water pump, and the cooling water takes away the heat inside the machine. Return the high-temperature hot water to the water tank again for cooling. With circulation and exchange cooling, the effect of cooling equipment is achieved. The invention applies the chiller to the molding die cooling of the plastic processing machine, which can greatly improve the surface smoothness of the plastic product, reduce the surface stripes and internal stress of the plastic product, speed up the product forming, and greatly improve the production efficiency of the plastic processing machine. The chiller can also be used for the lubrication of CNC machine tool spindles, coordinate boring machines, grinders, machining centers, combined machine tools and various precision machine tools and the cooling of the transmission medium of the hydraulic system. It can accurately control the oil temperature, effectively reduce the thermal deformation of the machine tool, and improve the machine tool. Precision. Industrial chillers are usually complete packaged closed loop systems including chiller and hot water units, condenser and circulating water pumps, expansion valves, internal cold water tanks and temperature control stations.
