Problems solved by technology

[0007] The present invention solves the problem that the air source heat pump air conditioning system in the prior art does not have condensation heat recovery, which not only leads to heat waste, but also causes urban heat pollution. The direct expansion solar heat pump hot water system only has a heating function, no cooling function, and is affected by Conditions have a great influence. The direct solar hot water production system also has only heating function, no cooling function. It is greatly affected by climate conditions, and the timeliness and reliability of heating are relatively low, so as to provide a condensing heat recovery type air Source-Solar Coupling Heat Pump Air Conditioning and Hot Water System

Abstract

The invention discloses a condensing heat recovery type air source-solar energy coupling heat pump air conditioning hot water system. The invention relates to a hot water system and aims at solving the problems in the prior art that an air source heat pump air conditioning system does not have the function of condensing heat recovery, thus heat is wasted, and urban thermal pollution can also be caused; and a direct expansion type solar heat pump hot water system and a solar direction production hot water system only have the heating function, do not have the refrigeration function and are largely influenced by weather conditions, so that the timeliness and the reliability of heating are both low. The condensing heat recovery type air source-solar energy coupling heat pump air conditioning hot water system comprises a compressor, an indoor unit, a four-way valve, an outdoor unit, a gas-liquid separator, a plate heat exchanger, a capillary tube, a double-pipeline flat plate solar collector, a water tank, a water pump, an electric three-way valve, an electric heater, a non-return valve, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve, a fourth electromagnetic valve, a fifth electromagnetic valve, a sixth electromagnetic valve, a seventh electromagnetic valve and an eighth electromagnetic valve. The invention belongs to the field of heat conversion.

Description

technical field [0001] The invention relates to a hot water system, in particular to an air source-solar coupling heat pump air-conditioning and hot water system with condensation heat recovery. Background technique [0002] Existing household heating, cooling and hot water heating systems with energy-saving and environmental protection benefits mainly include air source heat pump air-conditioning hot water system, direct expansion solar heat pump hot water system, and solar direct production hot water system. Both systems have obvious defects in practical application: [0003] 1. The outdoor unit of the air-source heat pump air-conditioning and hot water system is prone to frost in an environment with high relative humidity and low temperature. When the frost layer reaches a certain level, its heating capacity will be severely reduced. For a long time, frost prevention or defrosting Both are extremely difficult problems for air source heat pumps; at the same time, when app...
