Example Embodiment

[0020] An open-type heat pump hot water device based on air circulation, including a first air compressor 1, a turbo compressor 2, a second air compressor 3, a heat regenerator 4, an air / water heat exchanger 5 and an intermediate heat exchanger 6. The cold air in the atmospheric environment enters the regenerator 4 through the air inlet 11, enters the intake end of the first air compressor 1 after being preheated, and is discharged from the exhaust end after being compressed and heated by the first air compressor 1 , Enters the intermediate heat exchanger 6 to heat the circulating water flowing through the intermediate heat exchanger 6 for the first time; the air is discharged from the intermediate heat exchanger 6 and divided into two paths, one of which enters the compressor part 201 of the turbo compressor part 2, After being compressed and heated up by the compressor 201, it is discharged from the discharge end; the other way enters the intake end of the second air compresso...

Abstract

The invention discloses an open-type heat pump water heating device based on air circulation. A heat regenerator is utilized to perform one-stage preheating on air, a first air compressor, a second air compressor and a turbine air pressing part are utilized to perform two-stage compression on the air to prepare high-temperature air, and heating of circulating water is completed by performing two times of heat exchange through an intermediate heat exchanger and an air/water heat exchanger. The open-type heat pump water heating device can prepare building heat-supply water and domestic hot waterhigher than 60 DEG C in cold and chilly regions.

Description

technical field [0001] The invention relates to a hot water preparation device, in particular to an open heat pump water heating device based on air circulation. Background technique [0002] At this stage, the world is paying more and more attention to the issues of global warming and environmental protection. The heat pump is a cold and hot multiplexing device that can meet the diverse needs of cooling, heating and domestic hot water. However, in the selection of refrigerants, it is necessary to consider not only its environmental protection, but also its impact on efficiency. At present, HCFC (hydrochlorocarbon) refrigerants have been subject to more and more stringent controls. In addition, for the traditional vapor compression heat pump, there is a problem that the heating capacity is inconsistent with the change of the building heat load. When the outdoor ambient temperature drops, the building heat load increases, but the heating capacity of the traditional vapor com...
