Solar energy, soil source are regenerative resources, and solar energy is never exhausted clean energy resource, and the incomparable superiority of fossil energy is arranged.But solar radiant heat has intermittent and very large unstability, utilize solar energy, just must solve its discontinuity and unreliability problem.Soil source heat pump is stored in shallow surface and is close to unlimited regenerative resource, and is larger but buried heat exchanger is affected by soil function, and the heat transfer in the thermal property of soil, energy balance, the soil has considerable influence with biography is wet to heat transfer.The solar energy-ground source heat pump system is the system in conjunction with both characteristics combined heats, but system cost is too high, such as solar thermal collector cost boring expense etc., and huge heat collector area and ground heat exchanger lay area and bring difficulty to the enforcement of solar energy-ground source heat pump system.
Based on this, solar energy-soil source heat pump and existing city thermal pipe network are proposed in conjunction with complementary heating plant.
Summary of the invention
Purpose of the present invention: in order to take full advantage of solar energy and earth source heat pump advantage, remedy the deficiency of conventional energy resource heat supply network heat supply, realize the energy-saving and emission-reduction of northeast severe cold area central heating.
Technical scheme of the present invention:
The complementary heating plant of a kind of solar energy-ground source heat pump and heat supply network, it comprises solar thermal collector, heat storage water tank, ground heat exchanger, thermal-arrest circulating pump, temperature control three-way valve, expansion valve, supplies hot recycle pump, heat exchange circulating pump, it is characterized in that: described heating plant has three heating systems, the complementary heat supply of solar energy auxiliary heat supplying, soil source heat pump heat supply and heat supply network.
1. be that solar thermal collector (1) delivery port links to each other with heat storage water tank (2) bottom during the solar energy assistant heating system, heat water in the heat storage water tank (2) by solar thermal collector (1) heat-collecting capacity, be provided with temperature controller between solar thermal collector (1) and the heat storage water tank (2), the opening and closing of temperature controller control thermal-arrest circulating pump (4), when solar thermal collector (1) leaving water temperature is crossed when low, no longer to heat storage water tank (2) accumulation of heat, solar energy heating pump (1) quits work.Solar thermal collector is flat-plate solar heat collector, and heat storage water tank is the layering heat storage water tank.
2. the soil source heat pump heating system is that the delivery port of ground heat exchanger links to each other with heat storage water tank and carries out heat exchange, the junction is temperature control three-way valve, when the heat storage water tank temperature does not reach requirement, the heat storage water tank side closure of triple valve, underground pipe recirculated water directly enters evaporator with heat pump, thermo-compression evaporation side draught heat has heated the condensation side periodical feeding simultaneously.The heating end is to adopt the radiant floor heating mode.
3. with the complementary heating system of heat supply network, the water outlet of heat pump condensation side is supplied water with heat supply network and is connected heat exchange, and the junction is temperature control three-way valve, and when supply water temperature satisfied terminal demand, user's end side of triple valve was opened, and the heat pump water outlet is directly to the terminal heat supply of system.When supply water temperature does not satisfy the demands, heat supply network water supply side valve opening, terminad heat supply after the heat exchange of heat pump water outlet process heat supply network.Reverse-flow plate type heat exchanger also is installed in the system, is the equipment for heat pump water outlet and heat supply network heat exchange.
Advantage of the present invention and technique effect: take full advantage of the such regenerative resource of solar energy and soil source heat pump, the conventional energy resource heat supply is combined with the regenerative resource heat supply, realize environmental protection and economic dual value.In the solar energy-ground source heat pump system, add heat supply network, reduced capacity and the size in solar energy and source, ground, reduced the initial cost of system, improved simultaneously stability and the reliability of complementary heating system.Three kinds of energy of inferior proposition solar energy-soil source heat pump and heat supply network are in conjunction with complementary heat supply.This system more is applicable to the improvement project of existing building, on the basis of existing heat supply network, realizes reducing energy consumption.
Description of drawings
Fig. 1 is system schematic of the present invention.
Among the figure, the 1st, solar thermal collector, the 2nd, heat storage water tank, the 3rd, ground heat exchanger, the 4th, thermal-arrest circulating pump, the 5th, temperature control three-way valve, the 6th, expansion valve, the 7th, for hot recycle pump, the 8th, heat exchange circulating pump, the 9th, plate type heat exchanger, the 10th, evaporimeter, the 11st, condenser, the 12nd, compressor.
The specific embodiment
For invention is described further, now illustrated in conjunction with example.
When heat supply in winter initial stage and latter stage, solar energy resources is relatively abundant, the heat-collecting capacity that can take full advantage of solar thermal collector accumulation of heat in the heat storage water tank, utilize the auxiliary concurrent heating of solar energy to improve the soil source heat pump circulating water temperature, improve the inflow temperature of evaporator with heat pump, namely improved the efficient of source pump.When rainy weather occurs, can control temperature controller and stop solar energy to the accumulation of heat of heat storage water tank.Because temperature is excessively low, and the booster action of solar energy reduces greatly, can reduce the number of times of soil source heat pump recirculated water process heat storage water tank when heating mid-term by the conversion of temp .-control valve.And the at this moment heat supply of heat supply network is best, and by the control action of temperature-sensing valve, the water outlet of heat pump condensation side can improve supply water temperature by the further heat exchange of heat supply network, can reach terminal demand fully, realizes best heating effect.
