水源热泵的关键技术在于水井。水井的成井工艺极为重要，必须要求是大口径钢制管井。法国CIAT在水井方面有独到的技术和经验，在实际使用时可比传统方式节省部分井水用量，并能够成功实现同抽同灌。 由于水源热泵中央空调系统使用率极高，因此对设备的性能、质量要求也比较高，各种辅助设备和材料的合理匹配也是获得良好效果的基础。CIAT的一贯作风是施工中保持较高的工程水平，选用优质设备材料，将工程做成展示、宣传窗口，为业主带来更佳的社会效益。 中央空调系统是一项长期使用、可靠性要求高的工程，必须可以长期可靠运行，保证使用效果。在设计和施工中首要考虑的是严把质量关，确保工程的质量，并符合国家相关标准和规范的要求，无论方案设计还是设备选用、工程施工、打井回灌等各个环节都必须围绕着这个中心进行。 环境污染和能源危机已成为当今社会的两大难题，开发利用xx冷、热源能够为空调带来节能和环保双重效益，因而越来越受到人们的重视，水源（地温）热泵系统正是同时具备这些要求的一种中央空调技术。 水源（地温）热泵利用地表水作为冷热源，夏季水体温度比环境空气温度低，所以制冷的冷凝温度降低，使得冷却效果好于风冷式和冷却塔式，冬季水体温度比环境空气温度高，热泵循环的蒸发温度提高，能效比也提高；不存在空气源热泵的冬季除霜等难点问题。在利用水源（地热）热泵时应注意以下几个方面： 在采用水源热泵技术时，前期的水文分析尤为重要，必须根据地下水源实际情况，进行可行性的研究分析。适用的原则：水量充足、水温适当、水质良好、供水稳定、回灌可靠。因此，前期的认真、科学的水文地质勘探工作是非常必要的。 水源热泵中央空调主机，是冷热源的核心，它的质量好坏直接影响整个系统的可靠性和使用效果。建议选用国内外有良好信誉的厂家，尤其是技术质量优、生产历史久、售后服务好的xxxx。 众所周知，水源热泵空调的能效比（COP值，约等于输出功率／输入电功率）高于常规空调，但也有极限，但国内某些厂家标称其热泵机组能效比可达到7、8之多，甚至少数还有11、12。这是不符合实际、不科学的，是对用户的极端不负责任，是一种欺骗行为。

The key technology is the water source heat pump wells. Wells, well drilling technology is extremely important to have the requirements for large-diameter steel tube-wells. French CIAT in the wells have unique skills and experience in actual use than the traditional way to save part of the well water consumption, and can achieve the same success with the irrigation pump. As the water source heat pump central air conditioning system is so heavily used the equipment performance, quality requirements are relatively high, a variety of auxiliary equipment and materials are matched to obtain good results a reasonable basis. CIAT is a consistent style of construction projects to maintain a high level, high-quality selection of equipment and materials, the works show made to promote the window for the owners to bring a better social benefits. Central air-conditioning system is a long-term use, high-reliability engineering, must be able to long-term reliable operation to ensure the use of effects. In the design and construction of the first priority is strict quality control to ensure the quality of works and comply with relevant national standards and regulatory requirements, regardless of design or equipment selection, engineering, construction, drilling wells, recharge and other links have to be around This centers. Environmental pollution and energy crisis has become the two major problems in today's society, development and utilization of natural cold, heat can bring about energy-saving and environmentally friendly air-conditioned double-effectiveness, and therefore more and more attention has been paid, water (geothermal) heat pump system is also available These requirements of a central air-conditioning technology. Of water (ground temperature) heat pump utilization of surface water as a source of cold and heat, summer water temperature than the ambient air temperature is low, so condensation cooling lower the temperature, allowing the cooling effect is better than air-cooled and cooling tower, the winter water temperature than the ambient air temperatures are high, heat pump cycle of evaporation temperature rises, energy efficiency has also improved; there is no air-source heat pump in winter defrosting and other difficult problems. In the use of water sources (geothermal) heat pump should pay attention to the following aspects: In the use of water source heat pump technology, the pre-hydrological analysis has been particularly important for the actual situation must be based on groundwater sources to conduct feasibility research and analysis. Applicable principles: adequate water, proper temperature, good water quality, water supply stable and reliable recharge. Therefore, the pre-serious, scientific hydrogeological exploration work is necessary. Water source heat pump central air conditioning host, is the core of cold and heat source, which directly affects the quality of the overall system reliability and the use of effects. Suggested the use of domestic and foreign manufacturers have a good reputation, especially the excellent technical quality, production history, a long time, good after-sales service brands. As we all know, water source heat pump air-conditioning energy efficiency ratio (COP value, approximately equal to the output power / input power) is higher than conventional air-conditioning, but there are limits, however, some domestic manufacturers nominal energy efficiency of their heat pump units 7,8 can be achieved as much as, or even 11,12 There are a few. This is not realistic, unscientific and extremely irresponsible to users, is a cheating.
