Condenser
1) Role: A device which radiates heat to the outside of the refrigerator. As this heat is dispersed, the
high temperature/ high pressure vapor refrigerant changes to a liquid state.
2) Types
A. Air-cooling Type : Condense air by circulating naturally or manually.
1) Natural Convection Type : Used for the household refrigerator which has small condensing
capacity. (No Fan)
2) Manual Convection Type : Circulate air manually by FAN-Motor (Large capacity)
B. Water-cooling Type : Make cooling water pass through the pipe in the condenser
(Large capacity)

Location
①
CLUSTER heat-radiating type : All Pipes effective for radiating heat are formed in the right/
left, and front side of refrigerator with hard urethanes and radiate heat through the whole
surfaces of cabinet to ambient air.
②
Install the condenser on the outside of the product. (An old model)
③
Make them cluster at the lower part of product and radiate heat manually by fan.
※
Radiate condensed potential heat up to liquefy completely and make change the state without
changing the gas temperature itself.
※
Pipe thickness
①
Low pressure: 6.3mm
②
High pressure : 4.7mm
③
Capillary : About 0.4-0.8mm
※
Condenser length (Based on 300ℓ): 26.5 M
①
Assistance : 5 M
②
HOT-PIPE: 6.6 M
③
CLUSTER-PIPE: 4.17 M

Capillary
1. Role: A device which makes low temperature and pressure refrigerant by reducing the pressure
the normal temperature / high pressure liquid refrigerant condensed from condenser, and
supply it to the evaporator.
A. To evaporate more lower temperature in case of evaporation.
B. It flows to the evaporator without back flowing to condenser, if compressor stops, and the
difference of pressure between high pressure and low pressure is small so it is easy to
operate the compressor again.
2. Outline
A. Thickness : About 0.4-0.8ßÆ
B. Length : It is changeable to low temperature and pressure (10->5ß∏/ß≤) depends on the 2M
of thin and long copper pipe wall resistance.
