Description
Affiliated technical field
The utility model relates to the geological mapping field, especially a kind of ground thermal property proving installation.
Background technology
Geothermal heat pump air-conditioner speed increment with 20%-25% at present in China every year, scale turns to heavy construction, groups of building, sub-district from small and medium construction, the engineering that has reaches hundreds of thousands square metre, it is wherein perpendicular that to bury the buried tube type earth source heat pump application of U type ground more, perpendicular key of burying the buried tube type earth source heat pump success or not of U type ground is the design of ground heat exchanger, and the design of ground heat exchanger will directly have influence on the heat exchange effect of engineering economics and long-time running.And the design of ground heat exchanger is based on the ground thermal property parameter, and when 10% error took place for the coefficient of heat conductivity of ground or thermal diffusivity, then She Ji underground buried tube length variation then can reach 4.5～5.8%, and the variation of the total length that will cause holing.Because China is also very weak in the research in this field, even " earth-source hot-pump system engineering legislation " (GB50366-2005) among the appendix B data such as the coefficient of heat conductivity of listed ground, thermal diffusivity all are the test results of drawing from external, do not meet very much China and build development need.And the method for determining the ground thermal property parameter at present in the world mainly contains two kinds, first kind is the determined ground sample that takes out according to probing of international earth source heat pump association (IGSHPA) definite method of tabling look-up, because varying of various places geologic structure, look-up table obtains coefficient of heat conductivity and volume specific heat is not accurate enough, so this method exists error bigger in use; Second kind of cover that is people such as Austin sets up is used for the device of on-the-spot test ground thermal property, it mainly adopts the two Dimension Numerical method to obtain the coefficient of heat conductivity of soil, design very complicated, may reach hundreds of hours computing time, thereby its cost of goods manifactured and testing cost are all quite high, can not be by wide popularization and application.
Summary of the invention
In order thoroughly to break away from the present situation that China relies on external ground thermal property parameter, and overcome the deficiency of existing ground thermal property proving installation, the utility model provides a kind of ground thermal property proving installation, this ground thermal property proving installation not only can be implemented in the test job that ground thermal property is carried out at the scene, and it is simple to operate, test speed is fast, and test accuracy is also higher.
The technical scheme that its technical matters that solves the utility model adopts is: at the output terminal of water tank (10) valve (1) that is linked in sequence, flowmeter (2), tensimeter (3), thermometer (4) and U type water pipe (5), the other end of U type water pipe and thermometer (6), tensimeter (7), water pump (8) and valve (9) are linked in sequence, the other end of valve (9) is connected with water tank (10), in water tank, be provided with heating tube, heating tube is U type structure, wherein flowmeter (2), tensimeter (3) (7), thermometer (4) (6) is connected with data processor (11) respectively with temperature sensor (12).Heating tube can make the water temperature in the water tank remain on a stationary value, be beneficial to and improve the ground thermal property test accuracy, the ground initial temperature that data processor is gathered according to U type ground pipe laying import and export water temperature, flow, pressure and the temperature sensor gathered carries out the ground thermal property parameter that COMPREHENSIVE CALCULATING can draw this region.
The beneficial effects of the utility model are: not only can be implemented in the test job that ground thermal property is carried out at the scene, and it is simple to operate, test speed is fast, test accuracy is also higher, thoroughly broken away from dependence to external ground thermal property parameter, its product structure is simple, and cost is low, is convenient to promote the use of.
