Problems solved by technology
[0002] At present, in the air source heat pump industry, if the water outlet temperature is higher at a lower ambient temperature, due to the high compression ratio, the heat pump unit is prone to excessive exhaust temperature, which will cause the heat pump system to perform exhaust protection.
At present, the existing solutions to suppress the excessively high exhaust gas temperature under this condition are usually to directly open the main valve or the auxiliary valve, but these methods cannot effectively reduce the exhaust temperature, which makes the operating state of the heat pump system fluctuate Poor capacity, the compressor is prone to overheating protection, resulting in continuous liquid return or burning of the compressor

The invention relates to the technical field of heat pumps, and discloses a method for adjusting the exhaust gas temperature of a heat pump, which includes: collecting the exhaust temperature T1, the outlet water temperature T2 and the ambient temperature T3 of the heat pump unit; the heat pump unit enters a start-up stage; The low ambient temperature and the high outlet water temperature section and the main electronic expansion valve perform different adjustment processes; the heat pump unit enters the operation stage; the auxiliary electronic expansion valve and the main electronic expansion valve perform different adjustment processes according to the temperature range described by the exhaust temperature T1. Opening adjustment. Through the above method, the heat pump exhaust temperature adjustment method can effectively reduce the exhaust temperature and ensure the stable operation of the heat pump unit.
Description
technical field [0001] The invention relates to the technical field of heat pumps, in particular to a method for adjusting the temperature of exhaust gas of a heat pump. Background technique [0002] At present, in the air source heat pump industry, if the outlet water temperature is higher at a lower ambient temperature, the heat pump unit is very prone to the phenomenon of excessive exhaust temperature due to the high compression ratio, which will trigger the exhaust protection of the heat pump system. At present, the existing solutions to suppress the high exhaust temperature under this condition are usually to directly open the main valve or open the auxiliary valve, but these methods cannot effectively reduce the exhaust temperature, which makes the operating state of the heat pump system fluctuate. Poor capacity, the compressor is likely to cause overheating protection, which will cause the compressor to continuously return to liquid or burn out. SUMMARY OF THE INVEN...
