Air-cooled cold water heat pump air-conditioner hot water system

Abstract

The invention relates to a air-cooled cold water heat pump air-conditioner hot water system which comprises a air-conditioner hot water main system, wherein the air-conditioner hot water main system comprises a compressor, a four-way reversing valve component, a fin heat exchanger, a blower component, an electronic expansion valve component, an air-conditioner side reservoir, an air-conditioner side heat exchanger, a gas-liquid separator, a hot water heat exchanger, a hot water side reservoir and a non-return valve which are in connection through a pipeline, wherein the compressor is a general compressor or an enhanced vapor injection (EVI) compressor. The hot water system not only realizes the functions of refrigeration, heating, air-conditioner refrigeration heat recovery and separated water heating, but also achieves two defrosting manners so as to solve the defrosting problem under different application conditions; meanwhile, as the EVI technology is adopted, the hot water system can normally carry out heating or water heating under an extremely-low temperature environmental of subzero 5 to subzero 25 DEG C, and the heating water temperature can reach 55 DEG C, even 60 DEG C to the highest; and the hot water system, with the characteristic of energy conservation, can replace both electric water heaters and the gas water heaters.

Description

technical field

[0001] The invention relates to the field of air conditioning and hot water systems, in particular to an air-cooled cold water heat pump air conditioning and hot water system. Background technique

[0002] Air source heat pump hot water system has been accepted and recognized in household energy-saving life in recent years. However, because the payback period is usually more than 3 years, it is difficult to generally occupy the low-priced electric water heater and gas water heater market. On the other hand, due to the limitation of installation space and the improvement of people's living standards, more and more users begin to purchase and use air-cooled cold water (heat pump) air conditioners to improve the comfort of life.

[0003] With the development of commercial air-conditioning and hot water technology, people are paying more and more attention to domestic air-conditioning and hot water products, but they hope that the investment recovery period will...
