AI Technical Summary
Existing air source heat pump systems suffer from problems such as water temperature drop, poor heating effect, high energy consumption, long defrosting time and incomplete defrosting during defrosting, and there is also a risk of compressor liquid slugging damage, affecting the stability and reliability of the equipment.
The gas-electric complementary heating method is adopted. The gas heating equipment is started to heat the water circuit to maintain the initial water temperature. Combined with real-time monitoring of the outlet water temperature of the gas heating equipment and the exhaust temperature of the heat pump, the opening of the electronic expansion valve is dynamically adjusted to achieve reverse circulation defrosting.
It improves defrosting efficiency, enhances heating stability and energy efficiency, avoids compressor liquid slugging failure, and ensures stable operation of the equipment in low-temperature environments.
