Abstract
A tubular pile type ground source heat pump system is applied to construction heating, comprising a low-temperature heat source end, a ground source heat pump set and a radiating tail end; the system can be used in winter and summer; during heating, low-temperature hot water at an evaporator end of the ground source heat pump set is discharged into a hollow pipe of a concrete tubular pile embedded underground through a pipeline, and then, low-temperature hot water is heat-exchanged with the ground through the tubular pile wall; after heated, the low-temperature hot water is extracted to the evaporator end of the ground source heat pump set to be used as a low-temperature heat source, thereby realizing heating of the ground source heat pump system. The tubular pile type ground source heat pump system is capable of heating in winter while cooling in summer, and can ensure heat balance of underground soil; simultaneously, the system can solve the problems that the groundwater system lacks water and a soil pipe system has large floor area, thereby saving energy and protecting environment.
Description
Technical field
The present invention relates to a kind of earth-source hot-pump system, relate in particular to the low-temperature heat source end of earth-source hot-pump system.
Background technology
At present, the low-temperature heat source end of known earth-source hot-pump system generally adopts the lithic drainage soil pipe laying system that unifies, and such system high efficiency, energy-saving and environmental protection have obtained the application of wideling popularize of country.Ground water regime needs abundant groundwater resources, and the area of lack of water can't be used; Soil pipe laying system need take large-area vacant lot, is not suitable for wideling popularize and being limited in skyscraper and the little Application in Building of floor space.
The many regional geologies of China are loose, and building needs piling.Prestressed concrete pipe pile is made up of hollow pipe (external diameter 300mm-1000mm), concrete etc., and hollow pipe is buried underground, after water injects in portion, can be used for substituting the soil pipe laying system of earth source heat pump within it, is used for carrying out heat exchange with the earth.
With the immediate prior art of present technique be the patent of invention 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.
Summary of the invention
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.
The invention has the beneficial effects as follows: 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.
