| Zusammenfassung: | A refrigerating apparatus using coolant flow control value, with compressor, heat exchanger, pressure reducer and refrigerating circulation device. During the cooling operation, the coolant is flowed serially through the compressor, heat exchanger at heat source side, pressure reducer and heat exchanger at using side. And during the heating operation, the coolant is flowed serially through compressor, heat exchanger at using side, pressure reducer and heat exchanger at heat-source side. Its features are: The above switch device includes: Switching flow path for keeping the coolant flow path of heat exchanger at heat-source side and using side in a certain direction. The pressure reducer is connected with each coolant piping of heat exchanger at using side. The 1st flow control valve is used for adjusting coolant flow during cooling operation, and used for passing coolant flow at without pressure-lost status during heating operation. The 2nd flow control valve is used for adjusting coolant flow during heating |
