What is the role of the condenser and evaporator of the chiller?

The evaporator is one of the four core components of the chiller. In the evaporator, the refrigerant enters as a low-pressure liquid/vapor mixture and leaves as a low-pressure gas. At a constant temperature, the state changes from liquid to gas and absorbs energy. The evaporator of the chiller realizes superheated refrigerant vapor. Overheating means that all liquid refrigerant has evaporated and the gas temperature has risen above its saturation temperature. The process fluid enters as a hot liquid and exits at a lower temperature after transferring energy to the refrigerant. There are three types of evaporators in water chillers: coil type, shell and tube type, and plate exchange type. The structure chosen for different waterways is naturally different.

The condenser is one of the four core components of the chiller. In the condenser, the refrigerant enters as a high-temperature vapor and leaves as a high-temperature liquid. The condenser discharges the heat of the cooler to the surrounding air or cooling water. The condenser design covers the "total exhaust heat". This means that the condenser will remove the heat from the evaporator and compressor. The refrigerant leaving the condenser is a supercooled liquid. Subcooling means that all vapor refrigerant is cooled by the condenser to below its saturation temperature. Whether it is a water-cooled, air-cooled, or screw-type chiller, these two components must be indispensable. Condenser can be divided into two types: shell and tube type and fin type. The air-cooled chiller uses the fin type, and the water-cooled and screw type use the shell-and-tube type.5HP Air-cooled Plate Exchange Chiller is your good choice.
