Single Circuit U Tube Shell And Tube Heat Exchanger For Refrigeration System

Screw Chiller Single Circuit Dry Type

Shell and Tube Heat Exchanger

Chillers include four main components: compressors, evaporators, condensers, expansion valves, thus

achieving the unit refrigeration heating effect.

Chillers commonly known as freezers, refrigerators, ice machines, frozen water machines, coolers, etc.,

because the use of a wide range of industries, so the name also countless.

With the continuous development of chillers industry more and more people began to pay attention to the

chiller industry, any choice is more and more important for human beings, in the product structure "energy

efficiency than water-cooled screw unit", "water source heat pump unit", " Screw-type heat recovery unit

"," efficient heat pump unit "," screw-type low-temperature refrigeration unit "and so on the most

competitive product structure of its nature principle is a multi-functional machine, remove the liquid vapor

by compression or heat absorption Type refrigeration cycle.

The steam compression chillers consist of four main components of the vapor compression refrigeration

cycle compressor, evaporator, condenser, part of the metering device in order to achieve a different

refrigerant.

The absorption chiller uses water as a refrigerant and relies on a strong affinity between the water and

lithium bromide solution to achieve a cooling effect. Chillers are generally used in air conditioning units

and industrial cooling. In the air conditioning system, chilled water is usually assigned to the heat

exchanger or coil in the air handling unit or other types of terminal equipment to cool in their respective

spaces, and then the cooling water is redistributed back to the condenser to be cooled. In industrial

applications, chilled water or other liquid cooling pumps are through process or laboratory equipment.

Industrial chillers are used to control the products, mechanisms and factories of mechanical cooling of all

walks of life.

Chillers in the form of cooling can be divided into water-cooled and air-cooled, technically, water-cooled

than the air-cooled energy efficiency ratio higher than 300 to 500 kcal / h; in the installation, water cooling

to be included in the cooling tower can be used, Air cooling is movable and requires no other assistance.
