地源热泵是通过土壤的热量进行制冷制热,满足生活需要,但是各地土壤的条件都不同,究竟什么样子的土壤适合安装地源热泵,什么情况下水源热泵使用效率比较高呢?

Is the ground source heat pump refrigeration and heat through the soil heat, to meet the needs of life, but different soil conditions are different, exactly what the soil suitable for installation of ground source heat pump, water source heat pump under what circumstances the use efficiency is relatively high?

一、热工特性

Thermal characteristics

热工特性主要包括导热系数、容积热容量、热扩散率等。其中导热系数表示土壤传导热量能力的一个热物理特性指标,在数量上为Kcal/m·h·℃,土壤的容积热容量表征土壤的蓄热能力,而热扩散率则表征土壤温度场的变化速度。导热系数、容积热容量、扩散率因土壤成分、结构、密度、含水量的不同有异,并随着地区不同和季节的变化而变化。在同一地区,土壤的放热量是土壤吸热量的80﹪。

Thermal characteristics include thermal conductivity, volumetric heat capacity, thermal diffusivity, etc.. The thermal conductivity of soil heat conduction ability of a thermal physical properties, the number of Kcal/m - H - C, heat storage capacity of volumetric heat capacity characterization of soil, and the change rate of thermal diffusion is the representation of the soil temperature field. The coefficient of thermal conductivity, volumetric heat capacity and diffusivity vary with the composition, structure, density and water content of soil, and vary with different regions and seasons. In the same area, the heat release of soil is 80 percent soil heat absorption.

二、大地的温度

Two. The temperature of the earth

对大地土壤温度情况的了解是很重要的,因为大地与循环水之间的温差驱动热传递,大地温度接近全年的地表面平均温度,根据测定,10m深的土壤温度接近于该地区全年平均气温,并且不受季节的影响。

The earth temperature situation is very important, because the temperature difference between the earth and the water cycle driven heat transfer, the average surface temperature, the temperature close to the annual land according to the measured soil temperature of 10m deep in the area close to the annual average temperature, and will not be influenced by the season.

土壤的含水率是影响传热能力的重要因素,但水取代土壤微粒之间的空气后,它减小微粒之间的接触热阻提高了传热能力。土壤的含水量在大于某一值时,土壤导热系统是恒定的,称为临界含湿量,低于此时,导热系数下降,在夏季制冷时,热交换器向土壤传热,热交换器周围土壤中的水受热被驱除。

Soil moisture content is an important factor affecting heat transfer capacity, but when water replaces air between soil particles, it reduces contact thermal resistance between particles and improves heat transfer capability. The soil moisture is greater than a certain value, the soil heat conduction system is constant, that is lower than the critical moisture content, the thermal conductivity decreases, cooling in summer, the heat exchanger heat exchanger heat transfer to the soil, the soil around the heated water were expelled.

三 、地下水的流动

Three. Groundwater flow

地下水的渗流对大地的热传递有明显的效果。实际上,大地的地质构造很复杂,存在着松散的粘土层、砂层、沉积岩层、空气和水层等。由于地球构造运动,各岩层又出现褶皱、倾斜、断裂现象。

The seepage of groundwater has an obvious effect on the heat transfer of the ground. In fact, the geological structure of the earth is very complex. There are loose clay layers, sand layers, sedimentary rocks, air and water layers. Because of the tectonic movement of the earth, folds, tilts and fractures occur again.
