Title: method for controling the cooling system with 2 evaporator
Inventor: JUNG UI YEOP
IPC: F25B1/00
Filed: 2002-08-01
Abstract: PURPOSE: A method for controlling operation of a cooling system with two evaporators is provided to reduce time needed for refrigerant cycle to reach normal state by delaying operation of fans of the evaporators to which refrigerant is introduced on initial stage of switching of a three-way valve. CONSTITUTION: Refrigerant compressed in a compressor passes a condenser to be condensed and moves to a three-way valve. The three-way valve is controlled by a control part to be switched to an F evaporator installed in a freezer compartment. Condensed refrigerant having passed the three-way valve passes a first expansion unit to be expanded and become low temperature and low pressure gaseous refrigerant, and is introduced to the F evaporator. The refrigerant introduced into the F evaporator exchanges heat with air, and is re-introduced into the compressor to execute F cycle. An F fan corresponding with the F evaporator is controlled to rotate after fixed time has passed since the three-way valve is switched to the F cycle. Performance of heat exchange between refrigerant and air is temporarily reduced to allow the F evaporator to reach normal state more rapidly even when amount of refrigerant is not sufficient on initial stage on which refrigerant is introduced into the F evaporator.
