Fig. 1 is the system architecture schematic diagram.
The specific embodiment
Below in conjunction with description of drawings the present invention.
The present invention includes soil source heat pump system and apparatus for heating water by solar energy, the underground pipe port of export of soil source heat pump system and the pipeline between the evaporimeter are provided with heat exchanger 6.The outlet of the solar thermal collector 1 of solar energy servicing unit links to each other with the hot equipment 2 of storage through heat-collecting pump 3 by pipeline, storing hot equipment outlet links to each other with the heat collector import by pipeline, form the loop of heat medium, the heat exchanger on the pipeline between underground heat exchanger 4 ports of export of soil source heat pump system and the evaporimeter 7 links to each other with the hot equipment of the storage of apparatus for heating water by solar energy by pipeline.The solar thermal collector of apparatus for heating water by solar energy is the flat plate collector of single-glass cover plate, and scribbles the black selective membrane on the absorber plate surface.This solar thermal collector is towards the due south, the tilt adjustable joint, and its inclination angle winter is 45 °, spring, summer and autumn are 35 °.The hot equipment of the storage of apparatus for heating water by solar energy is single groove open type storage hot water storgae and is coated with heat-barrier material on hot equipment of storage and pipeline.Wherein the heat-barrier material thickness that coats at the hot equipment of storage is 20～50cm.The heat exchanger that is provided with on the underground heat exchanger exit end of described soil source heat pump system and the pipeline between the evaporimeter is a plate cold type heat exchanger.
Underground heat exchanger is a U type HDPE-100 plastic tube, and pipe embedded well is two mouthfuls, and the pipe laying diameter is respectively 25mm and 32mm, and pipe laying depth is 120m, and other establishes three mouthfuls of testing wells, and well depth is 90m, realizes that by circulating pump 5 water is in U type pipe and intrasystem circulation.Condenser 8 and evaporimeter 7 are plate type heat exchanger.End is established fan coil 9 air-conditioning systems.Connecting line partly adopts the PPR pipe, and in the winter time, source pump is by the operation of heat supply operating mode, and evaporimeter absorbs heat from soil by pipe laying, and the air-conditioner tail end equipment capable backwater is by the condenser heat temperature raising.In summer, by the valve member commutation, heat pump can be realized kind of refrigeration cycle.
Be solar energy system Winter heat supply process below: fine day, heat-carrying agent is thermal-arrest in heat collector, flows through the storage hot water storgae then, and by heat exchange coil in the groove with heat transferred water after, under the water pump effect, flow back to heat collector, beginning is circulation next time.In the accumulation of heat tank flow of hot water through heat exchanger with bury ground coil pipe outlet water and carry out heat exchange, return the tank heat exchange again.In cloudy day or evening, the thermal-arrest loop is out of service, heat release loop running, and for fear of freezing, the insulation measure has been taked in the heat release loop.In addition, solar energy system can be used for heat supply water in summer and transition season, because the regenerative apparatus with insulation measure is arranged, can be in summer with carrying out cold-storage running night, and realizes energy-conservation and help to miss the electric power peak, alleviation electrical network pressure.
