Abstract
The operating condition variation range of a heating system in the prior heat pump water heater is very large, and the pressure difference variation between the high pressure liquid cold medium at the outlet end of a compressor and the low pressure gas cold medium at the inlet end of the compressor is hardly regulated by only a capillary pipe or an expansion valve. The utility model provides a multi-way expansion gasification mechanism for a heat pump water heater, which comprises a capillary pipe (01) and an expansion valve (02). The multi-way expansion gasification mechanism is characterized in that the expansion gasification parameters of the capillary pipe (01) are configured in a lower temperature region with a heating system operating condition below 40 DEG C; the expansion gasification parameters of the expansion valve (02) are configured in an intermediate/high temperature region with the heating system operating condition above 40 DEG C (i.e. the regulation is stopped when the system operating condition is in the lower temperature region and started when the system operating condition is in the intermediate region or the high temperature region); and the capillary pipe (01) and the expansion valve (02) are connected into the expansion gasification step of the system in parallel, so as to satisfy the heating operating condition regulation in case of large span temperature variation, and improve the total energy efficiency ratio of the entire heating process.
