Directly-expanding solar heat-pump air conditioner water heater

Abstract

The invention provides a direct-expansion solar assisted heat pump water heater which belongs to the field of heating, air conditioning and domestic hot water equipments technology. It is comprised by outdoor unit (13), indoor unit (14) and hot water unit (15), wherein compressor (1) of the outdoor unit (13) is connected to B end of four-way valve (2); joint of the exhaust pipe is separated into two channels, wherein one channel goes through first solenoid valve (3), another channel goes through outdoor evaporation / condensation device (6), and then the two channels merge in one channel to connect A end of the four-way valve (2); D end connection tube of the four-way valve (2) is separated into two channels, wherein one channel goes through the outdoor evaporation / condensation device (6), another channel goes through solar energy collection / radiation device (4) and second solenoid valve (5), and then the two channels merge into one channel to connect to expansion valve assembly (8); another end of the expansion valve assembly (8) is separated into two channels, wherein one channel goes through third solenoid valve (9), another channel goes through the indoor unit (14), and then the two channels merge into one channel to connect to C end of the four-way valve (2). The invention has advantages of compact structure, multi functions, energy-saving and environmental protection.

Description

technical field [0001] A direct expansion solar heat pump air-conditioning water heater belongs to the technical field of heating, air-conditioning and domestic hot water equipment. Background technique [0002] Under the situation of global energy shortage and environmental deterioration, the energy saving of heating, air conditioning and domestic hot water has become an important topic of energy conservation and control of greenhouse effect. In industrially developed countries, building operation energy consumption generally accounts for more than 1 / 3 of the total energy consumption of society. According to conservative data, the current energy consumption of civil buildings in my country accounts for about 1 / 4 of the total energy consumption of the society. With the improvement of people's living standards, the proportion of building energy consumption will further increase. In my country's building operation energy consumption, heating, air conditioning and domestic wa...

AI Technical Summary

Problems solved by technology

[0005] At present, using direct expansion solar heat pump technology to design from the perspective of household central heating, air conditioning and hot water supply to form multi-connected or popular central air-handling household equipment abroad, there are very few reports. Reports need improvement in design, structure, controls, etc.
