Commercial Chiller Heat Exchanger

Shell and Tube Water - Cooled Evaporator

The central air conditioning system consists of one or more cold and heat source systems and a number

of air conditioning systems.

The principle of liquid vaporization is to provide the required cooling capacity for the air conditioning

system to counteract the heat load in the indoor environment.

The heating system provides the required heat for the air conditioning system to counteract the indoor

ambient cooling load. Refrigeration system is a vital part of the central air conditioning system, which uses

the type, operation mode, structure and other forms of direct impact on the central air conditioning system

in operation of the economy, high efficiency and rationality.

Air conditioning refrigeration technology is a common cooling range, mainly using liquid vaporization

refrigeration method. (Mainly the use of liquid vaporization process to absorb more latent heat, and the

liquid pressure is different, the boiling point is also different, the lower the pressure, the lower the boiling

point.)

According to the heat from high temperature objects to cryogenic objects in different ways, can be divided

into: Type refrigeration, absorption refrigeration.
