Independent refrigerating procedure of heat pump and hot water heating combined system

Abstract

The invention discloses an independent refrigerating procedure of a heat pump and hot water heating combined system and belongs to the technical field of air compressing type refrigerating air conditioner. In the independent refrigerating procedure of the heat pump and hot water heating combined system, an intelligent controller closes an ice condensing branch first switch valve (18) and an ice condensing branch second switch valve (19), opens an air source branch first switch valve (16) and an air source branch second switch valve (17), opens an air conditioner heat exchanger switch valve (8), closes a hot water heat exchanger switch valve (9), opens a first expansion valve (4), closes a second expansion valve (6), opens an air conditioner water pump (11), closes a hot water pump (12) and opens a heat exchange fan (10). Compared with the prior art, the independent refrigerating procedure has the advantages of being reliable in performances, high in operation efficiency, high in energy utilization rate and small in environment pollution.

Description

[0001] This patent is a divisional application with the application date of March 24, 2014, the application number 2014101111800, and the patent titled "Heat Pump and Hot Water Heating Combined System". technical field [0002] The invention belongs to the technical field of air compression refrigeration and air conditioning, and more specifically, belongs to a vapor compression and low-temperature heat source hybrid heat pump device system that utilizes energy in the air for refrigeration, heating and domestic hot water supply. Background technique [0003] The air-source heat pump air-conditioning device adopts a vapor compression refrigeration cycle system. The vapor compression refrigeration cycle system usually uses the low-grade energy in the outdoor atmosphere to provide thermal equipment for the air-conditioning system as a cold and heat source. At present, air-source heat pumps have been used in residential and commercial buildings. Has been widely used. The air sou...

AI Technical Summary

Problems solved by technology

During the cooling operation in summer, the air source heat pump air conditioner needs to discharge a large amount of condensation heat to the outdoor atmosphere when it is operating to cool the room, which will cause energy loss and environmental thermal pollution.

When heating in winter, the working efficiency of the air source heat pump air conditioner decreases sharply. When the temperature drops to a certain level, the air source heat pump air conditioner can hardly work normally. Therefore, the use of air source heat pump air conditioners in low temperature areas in winter has poor economic benefits and Difficulty running etc.

[0004] If air source heat pump air conditioners and heat pump water heaters are installed at the same time in commercial buildings or residential buildings, it will increase the overall equipment cost, operating cost and occupied space of the building.
