The technical solution of the utility model:A kind of inversion of phases solar auxiliary air energy heat pump hold over system, including the sun Energy collecting system, solar thermal collection system are connected through user's heating system with air energy thermal pumping system;Described solar energy heating System includes solar heat-collection plate, and solar heat-collection plate is through water pipe and water supply tank;Described user's heating system includes phase transformation Water tank, phase transformation water tank are connected through water pipe with indoor air cooling heat exchanger and water supply tank;Phase transformation is provided with described phase transformation water tank to store Thermal medium;Described solar thermal collection system in user's heating system with being in series with circulating pump.
In foregoing inversion of phases solar auxiliary air energy heat pump hold over system, described air energy thermal pumping system includes four Logical reversal valve, four-way reversing valve are connected through water pipe with phase transformation water tank, outdoor air cooling heat exchanger;In described air energy thermal pumping system Also it is in series with two opposite circulating pumps of loop direction;Described four-way reversing valve is also parallel with compressor.
In foregoing inversion of phases solar auxiliary air energy heat pump hold over system, described two loop directions are opposite to follow Check-valves is parallel with ring pump.
Beneficial effect
Compared with prior art, the utility model has the advantages that:
The utility model is made up of solar thermal collection system, user's heating system and air energy thermal pumping system, wherein Solar thermal collection system and air energy thermal pumping system provide heat, and user's heating system is then as thermal source for whole system Future, the heat of self-heat power was transported to terminal temperature difference.Solar thermal collection system is by water pipe series-connected solar collecting plate, water supply tank Formed with circulating pump, user's heating system is by water pipe series connection phase transformation water tank, indoor air cooling heat exchanger, water supply tank and circulating pump structure Into.Daytime can collect solar energy by solar heat-collection plate and be heated to the domestic water in water supply tank, and heat is provided for resident Water, use is more convenient, while unnecessary heat is accumulated into the phase-change heat accumulation medium in phase transformation water tank, effectively enhances and is The heat storage capacity of system, there is the characteristics of energy-efficient.The utility model set by four-way reversing valve, outdoor air cooling heat exchanger, The air energy thermal pumping system that four critical pieces of compressor and circulating pump are formed, when daytime temperature is higher, outdoor air-cooled heat exchange Heat in air (air energy) after working medium is collected, is flowed into compressor and further compresses heating, enter back into phase transformation water tank by device In, reject heat to phase-change heat accumulation medium;When heat supply, the recirculated water in user's heating system flows in the presence of circulating pump Enter water supply tank, absorb the heat from solar energy, enter back into phase transformation water tank, absorb the heat of phase-change heat accumulation medium, finally Heat is brought into indoor air cooling heat exchanger, reaches the purpose to indoor heating.By said structure, energy-saving ring is effectively reached The effect of guarantor.
The heat that the utility model can carry working medium in air energy thermal pumping system is finally with Water transport to indoor air-cooled Heat exchanger, and working medium only circulates in air energy thermal pumping system, without full of whole user's heating system, and then causes working medium Usage amount greatly reduces, and has the characteristics of economic, environmentally friendly.
In outdoor air cooling heat exchanger frosting, working medium carries out positive Kano and followed the utility model in the presence of four-way reversing valve The heat that ring, i.e. working medium absorb phase-change heat accumulation medium is defrosted, and defrosting, which finishes, to be continued to give phase transformation water tank against Carnot cycle Heat is provided;By the structure, automatic defrosting is effectively realized, use is more convenient.
It is of the present utility model simple in construction, it is easy to accomplish, it is effectively saved equipment cost.
