초록

A transport refrigeration system of the type which can provide either cooling or heating includes a pressure regulating valve 42 controlling hot gas to the evaporator during a heating cycle and operable to prevent an excessive suction pressure, and a pressure regulating valve 74 between the two outlet sides of a three-way valve and operable to pass refrigerant from the hot gas line 34 to the condenser 30 when the hot gas pressure is excessive, the arrangement limiting the values of both the evaporator suction pressure and the hot gas discharge pressure t...
