Abstract： |
The steam compressing refrigeration cycle device includes main cycle system comprising booster pump, condensator, expansion motor, evaporator and compressor connected successively with pipeline to output cold; and secondary cycle system comprising throttle connected across the inlet of the booster pump and the outlet of the condensator as well as the booster pump and the condensator, to further lower the temperature of the work medium in the outlet of the compressor. The expansion motor has its output torque rotating the booster pump and has isoentropic expansion to reduce the entropy of the work medium entering the condensator. The booster pump reduces the operation pressure difference and the power consumption of the compressor. Therefore, the present invention has energy efficiency near ideal inverse Carnot cycle and low hot load one compressor, and may be used widely in refrigeration cycle in air conditioner, refrigerator, etc. |
