Technical field
The utility model belongs to the cold and heat source system of building heating, air-conditioning and hot water supply, relates in particular to a kind of air source and solar energy combined heat pump system with auxiliary evaporator.
Background technology
Air source heat pump is based on a kind of heating, the air-conditioning equipment that contrary Carnot cycle principle is set up.Air source heat pump system obtains low-temperature heat source by natural energy (air accumulation of heat), becomes high temperature heat source after the system high efficiency thermal-arrest is integrated, and is used for heating or hot-water supply, and the whole system collecting efficiency is very high.Air source heat pump has four big advantages, and the firstth, energy-conservation, help the comprehensive utilization of the energy; The secondth, help environmental protection; The 3rd is the Cooling and Heat Source combination, and the utilization rate of equipment and installations height is saved initial cost; The 4th is that the adjusting control ratio is more convenient, so development in recent years is very fast.But; during the operation of air source heat pump Winter heat supply; a maximum problem is when outside air temperature is low, and the meeting frosting of outside evaporimeter heat exchange fin surface is as untimely defrost; frost layer knot more is thick more; influence air actual flow flux, and hindered the heat exchange on the coil pipe, weight person can be frozen; low-voltage variation appears in compressor shuts down, so regularly defrost.Most of in the market unit adopts recycled back to come defrost, and this moment, not only compressor stopped heat supply running, and made cooling operation, so system's heating load obviously is affected.When frosting was serious, average half an hourization is frost once, and the time of a defrost is about 5～10 minutes, and the heating load that reduces because of defrost reaches about 17%.In addition, reducing the COP value with outside air temperature under the Winter heat supply pattern sharply descends.Under 0 ℃ of condition, the actual of source pump exerted oneself to about 90% under the declared working condition.Exert oneself under-5 ℃ of situations and have only about 75% under the declared working condition, heating load has only about 60% under the declared working condition under-10 ℃ of conditions.And generally when outdoor temperature be lower than subzero 10 ℃ with regard to cisco unity malfunction.It is subzero that to be not suitable for adopting air source heat pump below 10 ℃ be conventional wisdom in the industry.Therefore, net for air-source heat pump units generally only is adapted at China south and uses, and is difficult to satisfy the heat load demand in northern area the coldest month in winter.For the air source heat pump technology being promoted in the whole nation, demand developing the air source heat pump that also can use under can a kind of cryogenic conditions in the winter time in the industry urgently.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of air source and solar energy combined heat pump system with auxiliary evaporator is provided, and the combined heat-pump system that constitutes two thermals source mutual supplement with each other's advantages is used for the building heating air-conditioner.Fundamentally solved the evaporimeter frosting problem, and increased substantially the actual of source pump and exerted oneself, consume conventional energy resource, utilize green, eco-energy to greatest extent thereby reach bottom line, solve building heating air-conditioner energy consumption, realize building energy-saving, environmental protection.
The utility model for achieving the above object, by the following technical solutions: a kind of air source and solar energy combined heat pump system with auxiliary evaporator, comprise heat pump apparatus of air source, it is characterized in that: on the heat pump apparatus of air source of routine, increase solar hot water heat collector, hot water storage tank and auxiliary evaporator, constitute the combined heat-pump system of two thermals source, the evaporimeter of described air source heat pump is in parallel with auxiliary evaporator by three-way valve, and auxiliary evaporator and solar hot water heat collector are communicated with hot water storage tank.
Described auxiliary evaporator places in the hot water storage tank for the tube bank of being made up of some intercommunication pipes, and its import and export is in parallel with the evaporimeter entry and exit of air source heat pump respectively.
Described auxiliary evaporator is a bushing type, comprises pipe in hot water sleeve pipe and the refrigerant, and the import and export of hot water sleeve pipe links to each other with hot water storage tank, and the pipe import and export is in parallel with the evaporimeter entry and exit of air source heat pump in the refrigerant.
The beneficial effects of the utility model: air source and two kinds of heat energy forms of solar energy are combined in the heat pump techniques, form the combined heat-pump system of having complementary advantages and be used for the building heating air-conditioner.Fundamentally solved the evaporimeter frosting problem, and increased substantially the actual of source pump and exerted oneself, consume conventional energy resource, utilize green, eco-energy to greatest extent thereby reach bottom line, solve building heating air-conditioner energy consumption, realize building energy-saving, environmental protection.
