Abstract

The invention relates to a steam jet enthalpy heat pump air-conditioning hot water unit which at least comprises a compressor, a four-way reversing valve, the four-way reversing valve, an outdoor heat exchanger, a refrigeration one-way valve, a liquid storage device, an economizer, an EVI electronic expansion valve, a refrigeration electronic expansion valve, an indoor heat exchanger, a steam-liquid separator, a heating one-way valve, a heating electronic expansion valve, a hot water one-way valve and a hot water heat exchanger. The technical problems to be solved by the invention is to provide the air-conditioning hot water system with the steam jet enthalpy function and realize the steam jet enthalpy under different modes through the control of the degree of superheat of the electronic expansion valves and an unique throttling structure, thereby improving the range of applications and the efficiency of an air conditioner, leading the functions of the system to be diverse, having high energy utilization rate, improving the efficiency under various modes to the maximum extent and being characterized by simple structure, easy control, low initial investment and low operation cost.

Description

technical field [0001] This patent belongs to the composition of refrigeration system, especially the air-conditioning and hot water system with the function of spraying steam to increase enthalpy and hot water, and belongs to the field of refrigeration and air conditioning. technical background [0002] In today's society, energy issues have increasingly become an important issue. Since the beginning of the 21st century, heat pump water heaters are highly energy-saving, that is, the advantages of 1 / 2 energy saving compared with gas water heaters have been widely used. The heat pump air conditioner and hot water unit derived from this has also become the focus of technical experts, and its characteristics are as follows: [0003] 1. Super large water volume: The capacity of the water tank can be customized according to customer requirements to meet the needs of different time periods. [0004] 2. Economical savings: the highest energy efficiency ratio can reach 6.0. [000...
