Abstract

During operation of an evaporator at a predetermined superheat degree, that position of heat transfer tubes which becomes a temperature at which frosting does not occur is determined as a specific position. Further, in the evaporator, the pitch of fins and/or the pitch of the heat transfer tubes on the refrigerant downstream of the specific position is denser than that on the refrigerant upstream so that the sum of cooling ability on the refrigerant upstream of the specific position and that on the refrigerant downstream of the specific position is not reduced. As a result, in cooling operation, frosting on the refrigerant downstream can be suppressed and the interval between defrosting operations can be set longer. In addition, because the pitch of the fins and/or the pitch of the heat transfer tubes on the refrigerant downstream side of the specific position is dense, a reduction in cooling ability is suppressed. The construction minimizes frosting on a cooler to extend the interval between defrosting operations.
