Title:
AIR SOURCE HEAT PUMP WATER HEATER FOR ECONOMIZER BUILT IN WATER-SIDE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2023/179729
Kind Code:
A1
Abstract:
The present application relates to the technical field of air source heat pump water heaters. Disclosed is an air source heat pump water heater for an economizer built in a water-side heat exchanger, which heater solves the technical problem of the whole device not being able to run normally due to a frosting situation occurring in a surface of an evaporator when an air source heat pump water heater is used for a long time, and an icing thickness further being increased if frost cannot be processed in a timely manner, and the technical problem of it being impossible to quickly disassemble and clean a heat exchanger. By means of a provided evaporator assembly, a high-temperature and high-pressure refrigerant is conveyed to a surface of an inner sleeve by using a set conveying hole, so as to perform cold and heat exchange on a frosted part on the surface of the inner sleeve, such that frost condensed on the surface of the inner sleeve is melted, and the situation of the whole device not being able to run normally due to an excessive frosting thickness is avoided; and secondly, melted water is drained by using a set air intake notch, thereby preventing the melted water accumulated in the interior of an outer sleeve from being frosted and frozen again, and thereby affecting a subsequent operation.
