Résumé

A heat pump has received much attention as substitute for the conventional boiler or heating coil because of its high efficiency. For the wide application of the heat pump, the most important design factor is the performance degradation upon its installation in tropical and cold regions. In this study, the effects of flash tank vapour injection on the heating performance of a two-stage heat pump with an inverter-driven twin rotary compressor were measured and analyzed for compressor frequency ranging from 50 to 100 Hz at ambient temperatures of -15, -5, and 5°C. The COP and heating capacity of the injection cycle were enhanced by 10 and 25%, respectively, at the ambient temperature of -15°C. The total mass flow rate of the injection cycle was 30-38% higher than that of the non-injection cycle.
