From the above description, it can be seen that the heat-supply system based upon geothermal energy that above example of the present invention provides has the following advantages：
It is combined using absorption heat pump and compression heat pump, to absorb a water drive of the low grade heat energy of GEOTHERMAL WATER
Dynamic absorption heat pump, then heat recovery, the absorption heat pump are carried out to a water for leaving absorption heat pump with compression heat pump
Profit is recycled as efficiently as possible instead of the electric heat pump driven in the prior art with high-grade energy, the compression heat pump in part
With the heat of GEOTHERMAL WATER, therefore, heat-supply system based upon geothermal energy energy high efficiente callback while reducing high-grade energy consumption utilizes ground
The heat of hot water.
For example, when using GEOTHERMAL WATER to carry out heat supply completely, when using the absorption of a heat-driven with GEOTHERMAL WATER
Heat pump and the mode of an electronic centrifugal heat pump combination carry out using recycling the heat of GEOTHERMAL WATER, relative to using two
For the heat-supply system based upon geothermal energy of the prior art of electric heat pump, it is possible to reduce power consumption 40% or so.
For another example when part uses GEOTHERMAL WATER, when partly boiler being used to carry out heat supply, the thermal energy with GEOTHERMAL WATER is used
Heat of the mode of electronic centrifugal heat pump combination to GEOTHERMAL WATER with the absorption heat pump of the heat-driven of boiler supplying and one
Amount using recycling, for the heat-supply system based upon geothermal energy using the prior art of two electric heat pumps, can also reduce
Power consumption 40% or so.
In addition, in the prior art, a water passes sequentially through generator and the evaporation of absorption heat pump in absorption heat pump
Water of device, above example of the present invention is evaporated merely through generator without absorption heat pump in absorption heat pump
Device, therefore, the resistance that a water need to overcome in absorption heat pump are only the resistance of generator, and the resistance of a water drops significantly
It is low, it can be from 15mH2O or more is reduced to 8mH2In addition O need not increase a water water hereinafter, water resistance is substantially reduced due to one time
It pumps to increase the lift of a water.
Further, since a water only needs to overcome in absorption heat pump the resistance of generator, it is supplied to generator
Lift greatly improve, under enough lifts, generator can design more flow numbers, and the velocity in pipes of generator is made to carry
High (can reach 1m/s or so), the heat exchange of generator can be improved 20% or so, even if to be not passed through absorption heat pump evaporation
The temperature of device, a water return water also can be relatively low to ensure the heat recovery of GEOTHERMAL WATER.
Further, part secondary water flows through absorption heat pump evaporator, on the one hand in absorption heat pump evaporator
Working medium evaporation provides heat, ensures the normal work of absorption heat pump.Moreover, because the part secondary water is passed through in absorption type heat
After the heat transfer process for pumping evaporator, increase with the temperature difference of a water in First Heat Exchanger, relative to without absorption heat pump
The heat of more water can be absorbed for evaporator, to the heat part phase released in absorption heat pump evaporator
It supports.On the other hand, the lift that is provided by secondary water water pump due to the resistance of evaporator is overcome, and the lift of evaporator is supplied to
It greatly improves, under enough lifts, evaporator can also design more flow numbers, and the velocity in pipes of evaporator is made to improve
(can reach 1m/s or so) also can be improved 20% or so to the coefficient of heat transfer of evaporator, be also beneficial to absorption heat pump
Efficient operation.
Further, increase the increasing of the coefficient of heat transfer with generator, evaporator with generator and evaporator velocity in pipes
Add, the volume of absorption heat pump can also reduce 10% or so.
Further, water system control method is simpler.Since in absorption heat pump, a water is only by hair
Raw device, when heat-supply system based upon geothermal energy, which is in the guard modes such as crystallization-preventive, anti-hypertonia, to be needed to shut down, in order to ensure geothermal heating
System remains to provide certain heating load, it is thus only necessary to a water of generator is bypassed, and evaporator by it is secondary
Water can maintain flow constant, and control method is simpler.
Finally it should be noted that：The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
It can modify to the specific implementation mode of the present invention or equivalent replacement is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
