ABSTRACT:
A refrigerating apparatus comprises two refrigerant circuits connected in a parallel fashion which include a common condenser. An evaporating temperature in an evaporator of one refrigerant circuit is set to a relatively high temperature compared with that of an evaporator of the other refrigerant circuit, so that a two-temperature evaporation type refrigerating apparatus is formed and a compressor of one refrigerant circuit can be intermittently driven for each predetermined time period in a forced manner. In a defrosting mode, the condenser is made to operate as an evaporator, whereby the evaporator included in the other refrigerant circuit is defrosted.
