            北京市是伟大祖国的首都，为改善空气环境、减少大气污染，市委市政府早在2000年就提出了大气污染治理规划。在城区内利用清洁能源取代燃煤锅炉，禁止新建燃煤锅炉。水源热泵空调作为一种清洁、节能、环保新技术很快被人们认识和接受。但在水源热泵系统的推广应用中，如何合理地抽取和回灌地下水是困惑用户的首要问题。在水文地质条件相对差的地区，回灌很难，出现了个别项目难以实现地下水的100％回灌，系统运行不稳定。 地源热泵空调系统正好弥补了水源热泵系统的不足，它通过密闭的PE换热管与地层进行热交换，为热泵提供冷热源，不再需要提取和回灌地下水。它的成功料浆泵应用和示范，使在水文地质条件较差的地区也能使用地能资源。本文将对比水源热泵和地源热泵系统，以及它们所适用的地质条件和地区，并通过对朝阳区绿化局办公楼地源热泵空调系统的介绍，使大家对地源热泵进一步了解。

         一、地能热泵系统的介绍 1、地能概述 人类赖以生存的地球蕴藏着丰富的各类矿产资源，同时它还是一个非常巨大的能量资源库。以浅层地表为例，据调查地表以下5～10米的地层温度就不随室外大气温度的变化而变化，常年维持在15～17℃。这样的温度相对于北京等的北方城市，冬季它比大气温度（5～-15℃）高，是可利用的低品位热源；油泵夏季它比大气温度（25～40℃）低，是可利用的冷源。 地能热泵系统就是利用地层的冬暖夏凉的特性，通过提取和释放地层中的热量，实现冬季供暖和夏季制冷。冬季通过输入1kW的电能，热泵机组可吸收2.5～3kW的地能，为建筑物提供3.5～4kW的热能；夏季通过输入1kW的电能，能为建筑物提供3.5～4kW的冷能。而该项目技术成功的关键就在于如何从地层中提取和释放热能。 水源热泵和地源热泵都属于地能热泵的范畴，不同之处就在于它们提取和释放地能的方式不同。 2、水源热泵和地源热泵 2.1水源热泵系统 水源热泵是通过抽取与地层同温度的地下水，机组与地下水换热后，地下水通过回灌井回灌到地层中。根据系统负荷量及需水量的大小，中开泵 地层的出水能力和回灌能力来设计抽水井和回灌井的数量。 抽灌井可为一抽一灌、一抽多灌或多抽多灌。 2.2地源热泵系统 地源热泵系统通过在密闭的换热管里循环的循环液与地层之间进行热量交换，冬季吸热、夏季散热。根据系统负荷量的大小，液下泵地层的导热能力来设计换热孔形式、数量和深度。

        二、北京市水文地质条件 北京市水文地质条件相对较好的地区在永定河古河道，潮白河古河道等，比较适合应用水源热泵的地区有：海淀区南部、石景山区、丰台区、大兴北部、城区、顺义县城东北部等部分地区。根据具体地点的水文地质条件不同，其单井的抽水量和回灌量都有所不同。基本上所有的地区都能使用地源热泵，但平原区，如海淀北部、朝阳区、昌平区、顺义南部、通县、大兴南部等地区，地层颗粒细换热孔施工容易，潜水泵 成孔费用相对较低；山区及山前地区，由于地层为岩石地层或颗粒较大，钻孔费用较高。

        三、结论 地源热泵系统是清洁、节能、经济并环保的技术，利用少量的电能即可实现供暖和供冷。同时换热孔系统不需要提取和回灌地下水，在水文地质条件较差的地区也能实现地能利用。地源热泵系统的推广和应用，将会促进“蓝天工程”的实施，在能源结构的调整中占有一席之地。

             Beijing is the capital of the great motherland, to improve the air environment, reduce air pollution, the municipal government put forward as early as 2000, the air pollution control plan. Use of clean energy within the city to replace coal-fired boiler, a ban on new coal-fired boilers. As a clean water source heat pump, energy saving, environmental protection and new technology quickly was recognized and accepted. However, the wide application of water source heat pump system, how reasonable is the confusion of groundwater extraction and recharge of the user's primary problem. Hydrogeological conditions in relatively poor areas, recharge is difficult, there has been difficult for individualfire pumps projects to 100% of groundwater recharge, the system runs unstable. Ground source heat pump systems make up the shortage of water source heat pump system, which closed PE Tube through heat exchange with the ground, for the heat pump to provide heat source, no longer need to extract and recharge groundwater. Its successful application and demonstration, so that in areas of poor hydrological conditions can also use geothermal energy resources. This article will contrast water source heat pump and ground source heat pump system, Yiji they apply to geological conditions and regions and through the Forestry Department office, Chaoyang District, ground source heat pump a systematic introduction, giving them a better understanding of ground source heat pump. First, in the introduction to heat pump system 1, to be able to outline Human life on Earth is rich in various mineral resources, while it is still a very large energy resource base. To shallow surface, for example, below the surface, according to survey 5 to 10 meters formation temperature outside air temperature does not change with the change,Split case pumps year-round maintenance of the 15 ~ 17 ℃. This temperature is compared to Beijing and other northern cities in winter than air temperature (5 ~ -15 ℃) high, low-grade heat source is available; summer than the air temperature (25 ~ 40 ℃) is low, is available cold source. Ground source heat pump system is used Dongnuanxialiang formation characteristics, formation and release by extracting the heat, winter heating and summer cooling to achieve. 1kW of electrical energy by entering the winter, heat pump can absorb 2.5 ~ 3kW of geothermal energy for the building to provide 3.5 ~ 4kW of heat; summer by entering the 1kW of electricity for the building to provide 3.5 ~ 4kW of cold energy. The key to the success of the project technology lies in how to extract from the formation and release of heat. Water source heat pump and ground source heat pump can heat pumps belong to the scope of difference is that they can Oil pumpsextract and release in different ways. 2, water source heat pump and ground source heat pump 2.1 Water Source Heat Pump System Water source heat pump is the same through the extraction and formation temperature of groundwater, and underground heat exchanger unit, the groundwater recharge through injection well to the formation. According to system load and water demand in the size of the formation of water capacity and recharge capability to design a pumping and recharge the number of wells. Pumping and injection wells for a smoke Vacuum pumpsa shrub, a pumping irrigation or pumping more and more irrigation. 2.2 Ground Source Heat Pump System Ground source heat pump system through a closed loop heat exchange in circulating fluid and heat exchange between ground, absorbs heat in winter and summer heat. According to system load size, formation of thermal heat transfer capacity to design holes form, quantity and depth. Second, Beijing, hydrogeological conditions Hydrogeological conditions are better in Beijing's ancient region in the Yongding river, Chaobai ancient river and so more suitable for water source heat pump application areas: the southern Haidian District, Shijingshan District, Fengtai District, Tai Hing North, Town, Shunyi County, northeast and other parts. According to site-specific hydrogeological conditions, the single well pumping and injection volume are different. Basically all of the regions can use ground source heat pump, but the plain areas, such as the northern Haidian, Chaoyang District, Changping District, Shunyi South, Datong County, southern Daxing districts, fine particles and ground heat exchanger construction is easy hole, hole relative costs lower; mountain and piedmont areas, the formation of rock strata or In-line pumpslarger particles, higher drilling costs. 3, Conclusion Ground source heat pump system is clean, energy saving, economic and environmentally friendly technology, electric power can be realized using a small amount of heating and cooling. At the same time the system does not require heat hole extraction and groundwater recharge, hydrogeological conditions in poor areas can be achieved in energy use. Promotion of ground source heat pump systems and applications, will promote the "blue sky project" The implementation of structural adjustment in the energy place.
