井房是以地下水为水源的灌溉工程建设中一个重要的部分，井房内通常安装水泵、配电柜、闸阀、变频器等设备。由于传统的砖混式井房不具备保温功能，极端气温对井房内的设备产生不利影响，甚至会造成设备损坏，缩短设备使用寿命。本文研发了一种新型的一体式保温井房，以太阳能为能源，利用碳热纤维对井房进行加热，井房外壁夹层中填充保温材料，安装基础采用泡沫板进行保温。大田试验表明，井房内外日均温差基本呈现抛物线分布情况，当井房外气温较高时，井房内升温值较小，当井房外气温较低时，井房内升温值较大，在冬季一体式保温井房内外温差最大值可达18℃左右。一体式保温井房可以使井房内在冬季升温明显，可以有效减少我国季节性冻土区井房内设备冻害发生。

Wells houses are an important part of the construction of irrigation projects relying on groundwater. Pumps, power distribution cabinets, valves, frequency converters and other equipment are installed in the houses. Extreme low temperature will bring adverse effects and even cause damage on equipment, as a result, shorten equipment service life. A new insulation well house is developed in this paper, and insulation materials are filled in the gap of its wall. The well house is heated through carbon fiber and solar energy and its foundation is insulated by foam boards. The field test results show that the profile of daily-averaged temperature difference between inside and outside of the well house is basically parabolic. The temperature difference is higher when outside temperature drops. The maximum temperature difference is up to 18 ℃ or so in winter. Results show the integrated well house will obviously and effectively reduce frost damage of equipment in seasonal frozen districts.
