<p>PROBLEM TO BE SOLVED: To improve a cooling capability with a simple device by a method wherein refrigerant flowed into a capillary tube is decreased in its temperature with condensed water formed at an outer part of an evaporator, thereafter the refrigerant is circulated through the capillary tube and the evaporator to a compressor. SOLUTION: When refrigerant flows a compressor 31, the refrigerant becomes a state of high temperature and high pressure and flows into a condenser 32. The flowed-in refrigerant heat exchanges with the surrounding air to become a state of room temperature and high pressure. Then the refrigerant primarily flows into the evaporator 33. The refrigerant is primarily cooled with condensed water generated during a heat exchanging operation between the evaporator 33 and the surrounding air. The cooled refrigerant is flowed into a flow divider 35 and uniformly distributed by a capillary tube 34. The refrigerant passes through the flow divider 35 and passes through many capillary tubes 34, thereafter the refrigerant is expanded and flows into the evaporator 33 under its low temperature and low pressure. The flowed-in refrigerant heat exchanges with the surrounding air, discharges the surrounding air removing heat to a location where an air conditioning is carried out so as to cool it. The refrigerant at the evaporator 33 absorbing heat flows again into the compressor 31. With such an arrangement as above, it is possible to improve a cooling capability by a simple device without increasing its manufacturing cost.</p> |
