Abstract
Refrigerating apparatus including a compressor, condensor and a plurality of evaporators which are connected in parallel and controlled by individual electromagnetic valves in response to temperature changes of individual evaporators. The refrigerating apparatus also includes an inverter circuit and a bypass circuit which causes refrigerant to flow from output side of the condenser to the input side of the compressor. When the temperature of the bypass circuit drops because of operation of the electromagnetic valves, the inverter circuit adjusts the operating frequency of the compressor.
