The condenser is an important device for the refrigeration system to concentrate heat release to the surrounding environment, which is one of the four major components of the refrigeration system. Condenser is a kind of heat exchanger, its main role is the high temperature refrigerant vapor quickly condensed into liquid, and exothermic to the outside world.
For vapor compression refrigeration system, the role of the condenser is the compressor discharged by the high-temperature refrigerant vapor condensation into liquid refrigerant. Condenser commonly used air, water and other room temperature fluid cooling, and sometimes also use a lower temperature of other fluid cooling. Condenser is a refrigeration system to the surrounding environment to focus on exothermic important equipment, is one of the four major components of the refrigeration system.
So, the condenser is good or bad or not will directly affect the size of the refrigeration system cooling capacity and refrigeration efficiency. With the continuous development of the refrigeration industry and the rapid expansion of the application of the surface, the condenser types are endless, the cooling capacity of the size of the difference, and the efficiency is constantly improving.
Condenser by a number of control devices:
(1) refrigerant controller: expansion valve, capillary tube, etc..
(2) Refrigerant circuit controller: four-way valve, check valve, compound valve, solenoid valve.
(3) refrigerant pressure controller: pressure opener, output pressure regulating valve, pressure controller.
(4) Motor protector: overcurrent relay, thermal overcurrent relay, temperature relay.
(5) temperature regulator: temperature position regulator, temperature proportional regulator.
(6) humidity regulator: humidity bit type regulator.
(7) defrost controller: defrost temperature switch, defrost time relay, various temperature switches.
(8) cooling water control: water cut-off relay, water volume adjustment valve, water pump, etc..
(9) alarm control: over-temperature alarm, over-humidity alarm, under-voltage alarm and fire alarm, smoke alarm, etc..
(10) other control: indoor fan speed controller, outdoor fan speed controller.
