At second group of heat donor passage.Two groups of heat donor passage joints are that end heating equipment 10 provides heat transfer medium, and the present invention is with hot water
For.
Specifically, in first group of heat donor passage, earth source heat pump unit 1 includes evaporator and condenser.Wherein, evaporator
Evaporator water inlet 14 and evaporator water outlet 13 respectively can heat source with the ground energy heat source water supply line 81 of ground energy heat source 8 and ground
Water return pipeline 82 is connected；The end that the condenser water inlet 12 of condenser passes through first circulation water pump 3 and end heating equipment 10
End water return pipeline 102 is connected, and leaving condenser water mouth 11 is then connected with the end water supply line 101 of end heating equipment 10.
Hot water from ground energy heat source 8 carries out heat exchange with the cold water from end heating equipment 10 in earth source heat pump unit 1, so that
After heat exchange gained cold water along ground can heat source water return pipeline 82 return ground can heat source 8, and gained hot water is along end feed pipe after exchanging heat
Road 101 flows into end heating equipment 10 and provides heat to the user.Further, the first energy meter water inlet of the first energy meter 5
52 and first energy meter water outlet 51 connect respectively with first circulation pump outlet 31 and condenser water inlet 12, to detect use
The actual heat that family uses.First circulation water pump water inlet 23 is connect with end water return pipeline 102, with for end water return pipeline
The flowing of cold water provides power in 102.
In the present invention, ground energy heat source 9 is set to around each heat supply point and suitable each heat supply point can be taken residing certainly
Any form of right environment, for example, the closed systems such as ground energy heat source, such as vertical underground pipe, horizontal underground pipe, underwater pipe laying,
Or the open system etc. using water source.
In second group of heat donor passage, heat exchanger 2 can select heat exchanger form commonly used in the art, such as plate-type heat-exchange

It connects, power is provided with the flowing for cold water in end water return pipeline 102.Further, motor regulated valve 7 is set to heat exchanger
Between 2 and second circulation water pump 4, that is, the valve water inlet 72 and valve outlet 71 of motor regulated valve 7 respectively with secondary side
Water inlet 21 is connected with second circulation pump outlet 41.
Use municipal heating system provided by the invention that can realize that based on ground energy heat supply, central heat source heat supply is
Auxiliary heat-supplying mode.That is, user can open/close motor regulated valve 7 according to specific requirements automatic/hand, with selectivity
The deficiency that ground enables central heat source heating can addedly heat.
Specifically, motor regulated valve 7 can be set to the automatic opening/closing when meeting certain condition.It is real one
It applies in example, when the water temperature in end water return pipeline 102 is consistently less than certain temperature within a certain period of time --- for example water temperature continues
10min-30min is less than 35 DEG C -40 DEG C --- when, motor regulated valve 7 would automatically turn on；On the contrary, working as end water return pipeline 102
Interior water temperature is persistently higher than certain temperature within a certain period of time --- and such as water temperature continues 10min-30min and is higher than 45 DEG C -50
DEG C --- when, motor regulated valve 7 will turn off.Furthermore it is possible to utilize the instantaneous energy data evaluation of the first energy meter
The ability of energy heat supply, if this data has reached the upper limit value of initial design instantaneous energy data, and supply water temperature is in
Continuous decrease trend can then open second group of heat donor passage, and calculate practical municipal administration by the detection data of the second energy meter and supply
The heat of hot systems.That is, when the instantaneous heat quantity of the first energy meter 5 display reaches ground energy 8 heat supply maximum value of heat source, and end return water
When continuing for some time --- such as 10min-30min --- water temperature in pipeline 102 and being in downward trend, motor regulated valve 7
It would automatically turn on, to be heated come the deficiency that can addedly heat using central heat source.
Municipal heating system according to the present invention is transmitted without heat transfer medium, is had based on 8 heat supply of ground energy heat source at a distance
Effect avoids energy waste, thus greatly reduces heat cost.On this basis, a kind of new charging method is provided：It is based on
The actual use heat that first energy meter and the second energy meter detect is charged.This charging method is eliminated according to building
The basic expense and unnecessary heat energy loss compensation that area is collected, user need to only carry out according to the giggio number of actual use
Payment, it is fairer and more reasonable compared to existing charging method.
Although an embodiment of the present invention has been shown and described, it will be understood by those skilled in the art that：Not
In the case of being detached from the principle of the present invention and objective a variety of change, modification, replacement and modification can be carried out to these embodiments, this
The range of invention is limited by claim and its equivalent.
