REFRIGERATOR

摘要

A refrigerator, comprising a two-stage compressor (12A) capable of efficiently cooling both a refrigerating compartment (2A) and a freezing compartment (5A). The high-pressure side outlet of the two-stage compressor (12A) is connected to a condenser (14A), the condenser (14A) is connected to a PMV (15A), and the refrigerating side outlet of the PMV (15A) is connected to the intermediate pressure side inlet of the two-stage compressor (12A) through a R capillary tube (16A) and a R evaporator (18A). The freezing side outlet of the PMV (15A) is connected to a F evaporator (26A) through a F capillary tube (24A), and the F evaporator (26A) is connected to the low-pressure side inlet of the two-stage compressor (12A) through a low-pressure suction pipe (28A). The PMV (15A) is switchable between a simultaneous cooling mode and a freezing mode. In the simultaneous cooling mode, the flow of a refrigerant flowing into the R evaporator (18A) is regulated by the PMV (15A) to control a temperature difference so that a difference between a temperature at the inlet of the R evaporator (18A) and a temperature at the outlet thereof becomes a set temperature difference (for example, 4°C).
