CONDENSING SYSTEM OF REFRIGERATOR

摘要

PURPOSE: A condensing system of a refrigerator is provided to improve condensing efficiency by joining an air-cooled condenser with a water-cooled condensing system or an evaporation type condensing system, and allowing only the air-cooled condenser to work or the air-cooled condenser and the water-cooled condensing system or the air-cooled condenser and the evaporation type condensing system to work together depending on outside air temperature, inside refrigerant pressure and condensing load. CONSTITUTION: An air-cooled condenser(100) includes a heat transfer tube(101) receiving high temperature and high pressure compressed refrigerant from a compressor, and bent zigzag; a plurality of fins(102) inserted to the heat transfer tube; and a condenser fan(103) placed on a front side thereof to forcibly introduce outside air so that the outside air is guided by the fins and exchanges heat with refrigerant flowing in the heat transfer tube. A water-cooled condenser(200) is installed on a refrigerant tube(201) placed between the compressor and the air-cooled condenser to allow water to flow in a water channel(202) near the refrigerant tube and exchange heat with refrigerant flowing in the refrigerant tube. A water inlet tube(203) and a water outlet tube(204) are connected to the water channel of the water-cooled condenser to allow water to be automatically supplied and discharged in a direction opposite to a direction in which refrigerant flows. An automatic water flow current control valve(205) is installed on an inlet side of the water inlet tube.
