Description
Technical field
This utility model relates to heat pump, particularly to a kind of earth-source hot-pump system.
Background technology
Earth-source hot-pump system is the eco-friendly power source profit that the novel energy utilizing superficial-layer geothermal energy to carry out heating and refrigerating utilizes technology
Use system.Earth-source hot-pump system is typically heat or cold in transfer underground and, to required place, also uses ground
The heat storage and cold accumulation ability that lower soil is huge, winter ground source heat is transferred in building from underground, summer is again ground
Under cold transfer in building, one year formed a cooling and heating circulation system, it is achieved the function of energy-saving and emission-reduction.
Earth-source hot-pump system is with Rock And Soil, subsoil water or surface water as low-temperature heat source, water source heat pump units, underground heat hand over
Change the heat-supply metering charge of system composition in system, building.The difference of base area heat energy exchange system form, earth source heat pump system
System is divided into buried pipe ground-source heat pump system, groundwater heat pump system and surface water source heat pump system.
As the Chinese patent " heat pump " of Application No. 201110312645.5 discloses the heat pump system of a kind of improvement
System, this heat pump is increase net for air-source heat pump units on existing earth-source hot-pump system, and this air source concurrent heating unit is permissible
Individually connect with air-conditioning equipment, thus when earth source heat pump unit operation poor-performing or output are not enough so that described heat pump system
System can individually or be combined with earth source heat pump unit to air conditioning system heating.Although, it is possible not only to maintain Soil Temperature Field
Thermal balance with year as cycle.Meanwhile, heat pump can also save the energy, reduces the cost of heat pump.
But, what this kind of earth-source hot-pump system was commonly used is that U-tube is used as buried heat exchanger tube, thus causes heat transfer
The U-tube that short or needs that the medium time of staying under soil compares are longer, and then be both unfavorable for improving geothermal energy
Utilization ratio, also can waste substantial amounts of tubing simultaneously.
Utility model content
The purpose of this utility model is that providing a kind of absorbs the earth-source hot-pump system that thermal efficiency is high from soil.
Above-mentioned purpose of the present utility model has the technical scheme that a kind of earth-source hot-pump system, bag
Include the buried pipe heat exchange system being arranged at earth source heat pump unit and being connected with earth source heat pump unit, described buried pipe heat exchange system
Including heat exchanger tube and heat exchange tank, the water inlet pipe one of described heat exchanger tube is connected with the outlet pipe two of heat exchange tank, described heat exchanger tube

As preferably, the tube wall of described heat exchange tank is equipped with some heat pipes one, described heat pipe one one end and heat exchange
The soil in the tank external world contacts, and the other end contacts with the energy storage aqueous phase within heat exchange tank.
The setting of heat pipe, can increase the heat exchange scope of heat exchange tank, thus beneficially energy storage water with away from heat exchange tank
Soil carries out heat exchange, is so more conducive to accelerate the water temperature change of energy storage water, and decreases the input amount of heat exchanger tube, from
And save ample resources.
As preferably, described heat exchanger tube is coil pipe.
Owing to heat exchanger tube is coil pipe, be so conducive to increasing the energy storage water flowed out in heat exchange tank and flow through in unit volume
Path, thus flowing during can also to a certain extent, enable energy storage water with manage outer soil carry out heat friendship
Change, thus the most just can improve the water temperature of energy storage water further.
As preferably, the even tube wall along described heat exchanger tube is distributed some heat pipes two.
The setting of heat pipe two can also expand the heat exchange scope of heat exchanger tube further, thus, it is also beneficial to energy storage water
The efficiency of heat exchange is carried out with the outer soil of pipe when flowing through heat exchanger tube.
As preferably, between described heat exchange tank and earth source heat pump unit, it is provided with water tank.
Although the water after earth source heat pump unit, substantial amounts of heat is had to be diverted, but, have comparison high
Temperature, therefore, be transported in water tank, can use as people's daily water consumption.
As preferably, the branch road of described water inlet pipe two is connected with water main, and described water main is provided with check (non-return) valve.
It is stored owing to part water enters in water tank, thus the water yield in heat exchange tank will reduce, in order to protect
The water yield that card is reserved, supplies water for heat exchange tank by opening water main, thus the abundance of the water yield in ensure that heat exchange tank, this
Sample is also just so that people can use the heat energy of abundance.Meanwhile, the energy storage in check (non-return) valve is possible to prevent heat exchange tank tank body
Water generation backflow phenomena, thus cause the loss of heat.
As preferably, in the horizontal segment of described water inlet pipe two, it is provided with drainage screen.
Due to the water transported out in water main or the most all carry certain through the water of earth source heat pump unit
Impurity, if without filtration, then will be attached to heat exchange tank tank body and the wall of heat exchanger tube body during life-time service
On face, thus the thermal resistance of heat exchange tank and heat exchanger tube will be increased, and then be unfavorable between energy storage water and soil carrying out heat exchange.
As preferably, the horizontal segment of described water inlet pipe two deviates from the lower internal face of current flow direction side in drainage screen
Having groove, the tube wall of described water inlet pipe two and groove corresponding section are provided with blow valve.
The impurity blocked by drainage screen can precipitate because of the effect of self gravitation current stop when, and
Groove just can receive these impurity.Precipitate in a groove it addition, can quickly be removed by unlatching blow valve, it is ensured that
The cleaning of water inlet pipe two so that current flow the most smooth and easy in water inlet pipe two.
