摘要： 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.

摘要： An expansion valve has a refrigerant inlet passage, a refrigerant outlet passage, a valve chest to which both the passages open, a diaphragm chamber communicating with a heat-sensitive bulb through a tube of small diameter, and a valve body actuated in response to the operation of a diaphragm, the valve body being disposed facing a valve seat in the valve chest to regulate a passage defined between the valve seat and the valve body, to thereby control the flow rate of a refrigerant. The valve seat is adapted to be axially movable along the inner wall of the valve chest. In addition, means are provided for moving the valve seat in accordance with a change in pressure in the refrigerant circuit.
