Description
Technical field
The present invention is soil and subsoil water connection seedbed source heat pump system, belongs to the energy, underground heat and air-conditioning technical neck
Territory.
Background technology
Soil source heat pump and groundwater heat pump, as the principal mode of earth source heat pump, are the most all conducts
Two kinds of completely self-contained system forms are applied, and do not develop both relatednesss, and it is true that
Both not only can be used in combination, and mutually close association, it is possible to mutually promote and mutually utilize.Can be big
The underground pipe heat exchange efficiency of big reinforced soil source heat pump, can reduce again groundwater heat pump and depend on groundwater run off
Rely and overcome drawbacks such as recharging difficulty, underground water source can be selected to make according to the amount of recharging that subsoil water is actual
Use degree.Building earth source heat pump can being suitable for becomes more commonly, and the earth source heat pump suitability is higher, application
More extensive.It is making full use of of underground two spike-type cultivars, is again the exploitation of two spike-type cultivars relatedness.
For simple soil source heat pump, it applies the reason placed restrictions on: heat exchanging capability of buried tube is low, pipe laying
Floor space is big, initial cost is high, to be applicable to outdoor sports big building, Energy Efficiency Ratio do not have groundwater heat pump
High.And if associating subsoil water is used in conjunction with, subsoil water not only can be utilized, and utilizes Groundwater Flow big
That improves greatly underground pipe takes heat energy power.Dual advantage, had both reduced the requirement to floor area, had made again one
Quantitative ground heat exchanger provides bigger Cooling and Heat Source, also reduces initial cost simultaneously.
For simple groundwater heat pump, it is suitable only for geological conditions goodish building location, with
Sample limits the application of earth source heat pump, and once geological conditions does not reaches requirement, abandons subsoil water the most completely
Utilization, this is to abandon the utilization of resources, energy-saving potential.And in fact subsoil water generally exists,
Even if overwhelming majority building can not utilize subsoil water in a large number, it is also possible to utilizes subsoil water on a small quantity, makes land used source
Heat pump.
Seepage action of ground water is the dynamic factor affecting earth source heat pump heat exchange efficiency, and can improve underground
Energy concentration and Dong Xia are load unbalanced.Seepage action of ground water, at the epigeosphere ground that earth source heat pump is utilized
In exist the most more or less.It is the biggest that the exchange capability of heat of earth source heat pump heat exchanger is affected by seepage action of ground water,
(Lv Yue, horse are the best etc. for the earth source heat pump monograph " design of earth source heat pump and application " published recently according to China
Compile) result of study: when groundwater velocity is 30 meter/year, i.e. during 10-6m/s, vertical-pipe heat exchanger
Exchange capability of heat is than without increasing about 30% during seepage flow, it is seen that the raising meaning of the increase heat exchanging ability of groundwater velocity
Justice is great.Seepage action of ground water is on the impact of soil heat exchanger on long terms, it is possible to take away Yin Dongxia load not
The energy balanced and gather in underground, makes soil source heat pump the most unrestricted in use, and fully profit
With.
But ground-source heat pump development is so far, on the impact of seepage action of ground water by not recognizing understanding, but the most passive
Ground accepts, and is not positively utilized.This new technique is i.e. actively to utilize subsoil water and accelerating ground water to ooze
Stream strengthens geothermal utilization amount, utilization ratio, and utilizes the subsoil water of extraction to take energy and accumulation of energy, makes underground
Water source mutually utilizes with soil source and is complementary to one another, and makes full use of respective advantage, overcomes respective unfavorable aspect.
It it is the efficient earth source heat pump form of a new generation.
