Conventional air source heat pumps suffer from frosting in winter and consume a large amount of electricity for defrosting. Meanwhile, ventilation recovery is an important approach to energy saving buildings. This paper conducts proof-of-concept study novel vapour injection pump. A prototype built tested. It has unique defrosting process driven by the warm exhaust In normal operation, first cooled down medium-pressure evaporator. then mixed with ambient low-pressure Both theoretical simulation experimental validation are carried out. The results show that proposed pump can significantly decrease thermodynamic irreversibility consumption, thus leading higher efficiency. For pump, coefficient performance increased 3.8 4.5 when temperature varied −5°C 10 °C. Furthermore, using fast efficient. duration (within 4 mins) less than 30% period at 0 °C, little power consumption. Consequently, demonstrated enhanced high flexibility feasibility. tackles challenges conventional promising cold climate area application.
