Abstract

See full text

If the degree of opening of an electronic expansion valve (14) is kept below a specified degree of opening or if the degree of superheat of refrigerant at an evaporator (15) side is kept above a specified degree of superheat, the amount of circulating refrigerant is judged to be insufficient. Thus, the volume of an air delivered by an evaporator fan (22) is reduced.
