What is a condenser system?

- Aug 02, 2018-

A type of condenser-heat exchange device used to cool fluids. Water or air is usually used as a coolant to remove heat. There are wall coolers, spray coolers, jacketed coolers and serpentine coolers. For example: for high-power silicon rectification and induction furnaces and medium-frequency furnaces, such as pure water, water, oil, oil and oil cooling devices, such as Guangzhou United Heating and Cooling Equipment Co., Ltd. The domestic senior manufacturer of products.


The cooler is mainly composed of a partition wall, hybrid and regenerative exchanger. The working principle of the cooler, heat transfer calculation, structural calculation, flow resistance calculation and design procedure are more illustrated in the heat exchanger book. And detailed examples.


Cold storage condenser: It is divided into single cooling type and cooling type heating type. No matter which type of structure is formed, it is composed of the following main components.


Refrigeration system: main components are compressor, condenser, evaporator, expansion valve (or capillary, subcooling control valve), four-way valve, double valve, check valve, solenoid valve, pressure switch, melting plug, output pressure regulation Valves, pressure controllers, reservoirs, heat exchangers, collectors, filters, dryers, automatic shutters, globe valves, filler plugs, and other components.


Electrical system: main components are motor (for compressors, fans, etc.), operating switches, electromagnetic contactors, interlocking relays, overcurrent relays, thermal overcurrent relays, temperature regulators, humidity regulators, temperature switches (defrost, Prevent freezing, etc.). Compressor crankcase heater, water shutoff relay, computer board and other components.


Control system: consists of multiple control devices, which are:Refrigerant controller: expansion valve, capillary tube, etc.


Refrigerant circuit controller: four-way valve, check valve, double valve, solenoid valve.


Refrigerant pressure controller: pressure switch, output pressure regulator, pressure controller.


Motor protector: over current relay, thermal overcurrent relay, temperature relay. temperature regulator:


Temperature level regulator, temperature proportional regulator. Humidity regulator: Humidity level regulator.

Defrost controller: Defrost temperature switch, defrost time relay, various temperature switches.


Cooling water control: water shut-off relay, water volume control valve, water pump, etc.


Alarm control: over temperature alarm, super humidity alarm, under voltage alarm and fire alarm, smoke alarm, etc.
