The scholar of China has carried out substantial amounts of theory and practice research to ground source heat pump technology, and many case histories have been thrown
Enter to use, achieve many achievements.But the research work that domestic scholars link to soil source heat pump and solar energy hybrid system
Start late.The researcher of Tianjin Business College has carried out on soil source heat pump and solar energy linked system first at home
Research, the heating performance that soil source heat pump and solar energy link was determined by year operating condition in 1994, was obtained
The coefficient of heat supply and heating load arrived under different supplying thermal conditions.
Summer in winter conditioning in Transition Season solar radiation amount before heating period is big, and the sunshine-duration is long, and solar cross season accumulation of heat purpose exists
Abundant storage of solar energy before using solar heat-preservation system by warm season is got up, and is used for heat supply in winter.Additionally, by
In under traditional earth source heat pump heat supply in winter operating mode, the reason for underground pipe caloric receptivity is much larger than heat release amount, easily occur with using
The increase of the time limit, underground pipe surrounding soil temperature drop ultimately results in earth-source hot-pump system and efficiency reduction even failure occurs
Situation.

Disconnected valve is opened, and central air conditioner system is substantially at working condition at full capacity, and solar energy system is not to accumulation of heat in soil, the 3rd water
Pump work, the 3rd water pump is by the first communication port of the first underground pipe and the first communication port of the second underground pipe to the first underground pipe
Hot water is extracted with the second underground pipe, hot water flows through the 3rd water pump, then flows to central air conditioner system, so that hot water is to central air-conditioning system
System heat supply, after hot water flows through central air conditioner system, temperature reduction, hot water becomes cold water, and cold water is again by the of the first underground pipe
Second communication port of two communication ports and the second underground pipe is flowed into the first underground pipe and the second underground pipe.It is in earth-source hot-pump system
While central air conditioner system heat supply, solar heat-collection plate can also absorb solar energy, by storage of solar energy in hot water storage tank.
For office building, the week is working day, it is necessary to heat, and two-day weekend at weekend is often to heat
's.Double free times stopped at weekend, the first on-off valve and the unlatching of the second on-off valve, the 3rd on-off valve and the 4th break-make can be utilized
Valve is closed, and using solar energy system to recharge heat in soil, recovers the soil moisture, and the soil moisture that the torrid zone is come is taken to working day
Decline, play a part of to adjust and supplement.
The utility model is joined together by solar energy system and earth-source hot-pump system, according to actual conditions and time together
Cooperate, on the one hand can using conditioning in Transition Season by storage of solar energy in soil for soil thermal storage for use in winter；It is another
Aspect, can be in the winter time simultaneously soil thermal storage in heat supplying process, recover the soil moisture, improve because underground pipe heat release amount is less than
Take soil moisture continuous decrease, the situation of earth-source hot-pump system failure that heat brings.
The utility model takes the same well of accumulation of heat on the basis of traditional earth-source hot-pump system under proposition supplying thermal condition, will
The underground pipe of solar energy system and the underground pipe of earth-source hot-pump system are arranged in same well, under supplying thermal condition, solar energy system
System and earth-source hot-pump system are cooperated, and accumulation of heat is carried out to soil while heat is taken, so as to play the work of the regulation soil moisture
With, it is to avoid earth-source hot-pump system causes system effectiveness to decline because long-term work makes soil moisture continuous decrease.
The utility model combines solar heat-preservation system and earth-source hot-pump system, can allow both mutually using each
From advantage, make up respective deficiency.One side soil has good stability and recovery electric heating system, when solar energy is inadequate
