With the immediate prior art of present technique be the utility model patent that the application of light energy-saving type air conditioner is preserved in Dalian, the patent No. is: 200510072544.X, name is called " central air conditioner system of utilizing concrete tubular pile hollow pipe substituted cooling tower ".The scheme of this patent is: the water that has condensation heat that the central air-conditioning refrigeration machine is produced passes through pipeline, is discharged in the hollow pile and dispels the heat, and by another pipeline the bottom of cooled water from hollow pipe is drawn into the refrigeration machine, thereby water is recycled.This programme in refrigerated area use in summer, utilizes in the time of can not heating in the winter time only.And after operation in a few years, can destroy the soil heat balance of concrete tubular pile region, and cause subsurface temperature to raise, can reduce the efficient of system, system's cisco unity malfunction when serious.
The utility model content
Utilize during heat supply in the winter time in order to overcome prior art, and destroy the problem of the soil heat balance of concrete tubular pile region, this programme has designed pile tube formula earth-source hot-pump system.Being achieved in that of this programme is discharged to the evaporator end low-temperature water heating that heats earth source heat pump unit in the process buried in the hollow pipe of underground concrete tubular pile by pipeline, low-temperature water heating is by pile tube wall and the earth heat exchange, the evaporator end that is drawn into the earth source heat pump unit again after the intensification is as low-temperature heat source, thus the heating of realization earth-source hot-pump system.Summer is when freezing, be discharged to the condenser end high-temperature-hot-water of earth source heat pump unit buried in the hollow pipe of underground concrete tubular pile by pipeline, high-temperature-hot-water is by pile tube wall and the earth heat exchange, the condenser end that temperature is drawn into the earth source heat pump unit after descending again is as cooling water source, thus the refrigeration of realization earth-source hot-pump system.The native system Winter-summer dual purpose, thus realize the soil heat balance of concrete tubular pile region, make system keep long-term normal operating condition.
Concrete technical scheme of the present utility model is: system comprises low-temperature heat source end, earth source heat pump unit, heat radiation end, heat in the process, the evaporator end of earth source heat pump unit links to each other with the water lift pipeline with water return pipeline, and these two pipeline other ends are linked concrete tubular pile hollow pipe; In the process of refrigerastion, the condenser end of earth source heat pump unit links to each other with the water lift pipeline with water return pipeline, and these two pipeline other ends are linked concrete tubular pile hollow pipe.
Also can in system, increase preposition heat exchanger in addition, promptly heat in the process, the preposition heat exchanger of system links to each other with the water lift pipeline with water return pipeline, and these two pipeline other ends are linked concrete tubular pile hollow pipe, and preposition heat exchanger opposite side links to each other with the evaporator end of earth-source hot-pump system; In the process of refrigerastion, the preposition heat exchanger of system links to each other with the water lift pipeline with water return pipeline, and these two pipeline other ends are linked concrete tubular pile hollow pipe, and preposition heat exchanger opposite side links to each other with the condenser end of earth-source hot-pump system.
The beneficial effects of the utility model are: utilize pile tube formula earth-source hot-pump system can realize Winter heat supply, and can freeze summer, realize the soil heat balance of concrete tubular pile region, make system keep long-term normal operating condition.Problems such as the floor space of the water shortage problem of ground water regime and soil pipe laying system is big, energy-conserving and environment-protective have been solved simultaneously.
