Refrigerating freezing and quick freezing storage apparatus

摘要

A refrigeration, freezing and quenching storage device is disclosed. The disclosed refrigeration, freezing and quenching storage device comprises compressors composed of a first condenser, a second condenser and a third compressor connected in parallel; A condenser for condensing the refrigerant compressed in the compressors; A quench chamber evaporator capable of evaporating the refrigerant passed through the condenser and providing quenching to the quench chamber; A freezer compartment evaporator capable of evaporating the refrigerant passed through the condenser and providing freezing to the freezer compartment; A refrigerating chamber evaporator capable of evaporating the refrigerant passed through the condenser and providing refrigeration to the refrigerating chamber; An evaporator pressure regulating valve (EPR) disposed between the freezer compartment evaporator and the compressors; A refrigerating chamber side evaporation pressure regulating valve disposed between the refrigerating compartment evaporator and the compressors; And a quenching chamber side evaporation pressure control valve disposed between the quench chamber evaporator and the compressors. According to the disclosed refrigeration, freezing and quenching storage device, compressors composed of a first condenser, a second condenser and a third compressor in which refrigerating, freezing and quenching storage devices are connected in parallel; A condenser for condensing the refrigerant compressed in the compressors; A quench chamber evaporator capable of evaporating the refrigerant passed through the condenser and providing quenching to the quench chamber; A freezer compartment evaporator capable of evaporating the refrigerant passed through the condenser and providing freezing to the freezer compartment; A refrigerating chamber evaporator capable of evaporating the refrigerant passed through the condenser and providing refrigeration to the refrigerating chamber; A freezing chamber side evaporation pressure regulating valve disposed between the freezer compartment evaporator and the compressors; A refrigerating chamber side evaporation pressure regulating valve disposed between the refrigerating compartment evaporator and the compressors; And a quenching chamber side evaporation pressure regulating valve disposed between the quench chamber evaporator and the compressors. Accordingly, the object to be stored can be stored by refrigeration, freezing, and quenching without using an expensive two-stage compressor.
