地源热泵系统在三层独栋别墅中设计+CAD图纸
地源热泵技术的原理是，是利用地下的土壤、地表水、地下水温相对稳定的特性，通过消耗电能，在冬天把低位热源中的热量转移到需要供热或加温的地方，在夏天还可以将室内的余热转移到低位热源中,达到降温或制冷的目的。地源热泵不需要人工的冷热源,可以取代锅炉或市政管网等传统的供暖方式和中央空调系统。冬季它代替锅炉从土壤、地下水或者地表水中取热，向建筑物供暖；夏季它可以代替普通空调向土壤、地下水或者地表水放热给建筑物制冷。同时，它还可供应生活用水，可谓一举三得，是一种有效地利用能源的方式。

The design and application of GSHP system in the villa
Abstract: As the development of the production and the science technology, human also conducted a series of improvements of ground source heat pump heating technology. At the same time they also try to find ways to make the ground source heat pump more environmental and Energy saving. Now use the mature electronic technology to carry out comprehensive control and combined with the solar energy to pay more attention to the comprehensive utilization ,energy saving ,the protection of the environment ,must be the theme of the development in the future.
The ground source heat pump technology,is a technology which use the characteristics of temperature is relatively stable of the soil underground ,surface water, groundwater to transfer heat from ground to anywhere that need it in the winter or cool the indoor temperature by let the heat flue into the ground. The ground source heat pump does not need a man-made cold source, it can take the place of the traditional heating and central air conditioning system such as the boiler or municipal pipeline. It can also supply the water for living ,what a convenient way it is.
Key Words：ground source heat pump; central air conditioning; Fan coil
