Description
技术领域technical field
本实用新型属于换热系统技术领域，具体涉及一种水平换热和垂直换热相结合的地源热泵系统。The utility model belongs to the technical field of heat exchange systems, in particular to a ground source heat pump system combining horizontal heat exchange and vertical heat exchange.
背景技术Background technique
地源热泵是陆地浅层能源通过输入少量的高品位能源(如电能)实现由低品位热能向高品位热能转移的设备。通常地源热泵消耗1kWh的能量，用户可以得到4.4kWh以上的热量或冷量。The ground source heat pump is a device that transfers low-grade thermal energy to high-grade thermal energy by inputting a small amount of high-grade energy (such as electric energy) from shallow land energy. Usually the ground source heat pump consumes 1kWh of energy, and the user can get more than 4.4kWh of heat or cold.
地源热泵已成功利用地下水、江河湖水、水库水、海水、城市中水、工业尾水、坑道水等各类水资源以及土壤源作为地源热泵的冷、热源。地源热泵技术属可再生能源利用技术。由于地源热泵是利用了地球表面浅层地热资源(通常小于400米深)作为冷热源，进行能量转换的供暖空调系统。地表浅层地热资源可以称之为地能，是指地表土壤、地下水或河流、湖泊中吸收太阳能、地热能而蕴藏的低温位热能。地表浅层是一个巨大的太阳能集热器，收集了47％的太阳能量，比人类每年利用能量的500倍还多。它不受地域、资源等限制，真正是量大面广、无处不在。这种储存于地表浅层近乎无限的可再生能源，使得地能也成为清洁的可再生能源的一种形式。Ground source heat pumps have successfully used various water resources such as groundwater, river and lake water, reservoir water, seawater, urban reclaimed water, industrial tail water, tunnel water, and soil sources as cold and heat sources for ground source heat pumps. Ground source heat pump technology is a renewable energy utilization technology. Because the ground source heat pump is a heating and air conditioning system that uses shallow geothermal resources on the earth's surface (usually less than 400 meters deep) as a cold and heat source for energy conversion. Surface shallow geothermal resources can be called geothermal energy, which refers to the low-temperature thermal energy stored in surface soil, groundwater, or rivers and lakes by absorbing solar energy and geothermal energy. The shallow layer of the earth's surface is a huge solar heat collector, which collects 47% of the sun's energy, which is more than 500 times the energy used by human beings every year. It is not limited by regions, resources, etc., and it is truly ubiquitous and ubiquitous. This kind of renewable energy stored in the shallow layer of the earth's surface is almost unlimited, making ground energy a form of clean renewable energy.
按照其地源热泵系统的循环运行形式分，主要去有开式和闭式两种，开式系统是指地表水在循环泵的驱动下，经过处理直接流经水源热泵机组或者通过中间换热器进行热交换的系统；闭式系统是在深埋于地下的封闭塑料管内，注入防冻液，通过换热器与水或土壤交换能量的封闭系统。According to the cycle operation form of the ground source heat pump system, there are mainly two types: open type and closed type. The open type system means that the surface water is driven by the circulating pump, and after treatment, it flows directly through the water source heat pump unit or through intermediate heat exchange. The closed system is a closed system in which antifreeze is injected into a closed plastic pipe buried deep in the ground, and energy is exchanged with water or soil through a heat exchanger.
由于闭式系统不受地下水位、水质等因素影响，因此使用范围最广。闭式循环系统又包括两种形式，其一是垂直埋管：深层土壤垂直埋管可获取地下深层土壤的热量。垂直埋管通常安装在地下50-150米深处，一组或多组管与热泵机组相连，封闭的塑料管内的防冻液(塑料管中是水，水中的防冻液根据当地气候条件决定加多少)将热能传送给热泵，然后由热泵转化为建筑物所需的暖气和热水。垂直埋管是地源热泵系统的主要方式，得到各个国家的政府部门大力支持；其二是水平埋管：在地下大约2米深处水平放置塑料管，塑料管内注满防冻的液体，并与热泵相连。水平埋管占地面积大，土方开挖量大，而且地下换热器受地表气候变化的影响。Since the closed system is not affected by groundwater level, water quality and other factors, it is the most widely used. The closed circulation system includes two forms, one is the vertical buried pipe: the deep soil vertical buried pipe can obtain the heat of the deep underground soil. The vertical buried pipe is usually installed at a depth of 50-150 meters underground. One or more groups of pipes are connected to the heat pump unit. ) transfers heat energy to the heat pump, which is then converted into heating and hot water for the building. Vertical buried pipe is the main method of ground source heat pump system, which has received strong support from government departments of various countries; the second is horizontal buried pipe: place plastic pipes horizontally at a depth of about 2 meters underground, and fill the plastic pipes with antifreeze liquid and mix them with Heat pump connected. The horizontal buried pipe occupies a large area, and the amount of earth excavation is large, and the underground heat exchanger is affected by the change of the surface climate.
然而，地源热泵要实现制冷制热，则需要给它提供动力来输送制冷制热管道中的循环水，传统机房可提供动力，但存在施工复杂，难度高，周期长，采购的材料种类多，需库存，漏水隐患大等问题。并且在运行使用的过程中，某些地区的现场管理人员会发现这样的问题：在运行的的时候，为了获得投资带来的最大效益化，垂直换热系统5的换热量会有所剩余，而水平换热系统4的换热量却显得不足，并且在垂直换热系统5单独运行时，由于靠近地表附近的热损失逐渐增大，当地下换热器的换热量到达地上机房时，就会损失大量的热量或冷量，这无疑是对能源的极大浪费。However, in order to realize cooling and heating, the ground source heat pump needs to provide power to transport the circulating water in the cooling and heating pipes. Traditional machine rooms can provide power, but there are complex construction, high difficulty, long cycle, and many types of materials purchased. , Inventory is required, and there are many hidden dangers of water leakage. And in the process of running and using, on-site management personnel in some areas will find such a problem: During operation, in order to obtain the maximum benefit brought by investment, the heat exchange capacity of the vertical heat exchange system 5 will be leftover , while the heat exchange capacity of the horizontal heat exchange system 4 is insufficient, and when the vertical heat exchange system 5 operates alone, due to the heat loss near the surface gradually increases, when the heat exchange capacity of the underground heat exchanger reaches the above-ground machine room , will lose a lot of heat or cold, which is undoubtedly a great waste of energy.

下面结合附图和具体实施方式对本实用新型进行详细说明。The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
本实用新型提供的一种水平换热和垂直换热相结合的地源热泵系统的结构如图1所示，包括换热设备1、垂直换热系统5以及环绕于垂直换热系统5的水平换热系统4，垂直换热系统5和水平换热系统4相连通并通过两条传输管线3与换热设备1循环连接。具体的，为了增大换热面积，增加换热量和提高换热效率，水平换热系统4设置于地下2-3米，水平换热系统4设置为多圈环绕垂直换热系统5、并与垂直换热系统5相连通的换热管，换热管内流通防冻换热液体。垂直换热系统5为竖直设置的换热管，换热管内流通防冻换热液体，垂直换热系统5末端的换热管为多段曲折结构。The structure of a ground source heat pump system that combines horizontal heat exchange and vertical heat exchange provided by the utility model is shown in Figure 1, including heat exchange equipment 1, a vertical heat exchange system 5 and a horizontal The heat exchange system 4 , the vertical heat exchange system 5 and the horizontal heat exchange system 4 communicate with each other and are circularly connected with the heat exchange equipment 1 through two transmission pipelines 3 . Specifically, in order to increase the heat exchange area, increase the heat exchange capacity and improve the heat exchange efficiency, the horizontal heat exchange system 4 is set 2-3 meters underground, and the horizontal heat exchange system 4 is set as a multi-circle surrounding vertical heat exchange system 5, and The heat exchange tube connected with the vertical heat exchange system 5, the antifreeze heat exchange liquid circulates in the heat exchange tube. The vertical heat exchange system 5 is a heat exchange tube arranged vertically, and the antifreeze heat exchange liquid circulates in the heat exchange tube, and the heat exchange tube at the end of the vertical heat exchange system 5 has a multi-section zigzag structure.
进一步的，在传输管线3上设置阀门2，通过控制阀门2的开合程度来控制整个地源热泵系统的开启、关闭以及调节所传输的冷量或热量的大小。Further, a valve 2 is provided on the transmission pipeline 3, and the opening and closing of the entire ground source heat pump system is controlled by controlling the degree of opening and closing of the valve 2, and the amount of transferred cold or heat is adjusted.
本实用新型是由一套完整的垂直换热系统5、一套完整的水平换热系统4以及换热设备1连接配合起来的地源热泵系统，主要包括一套室内的换热设备1，用于将换取的热量或冷量处理后送往末端系统；一套传输管线3，用于冷量或热量的输送和传递；阀门2用于控制地源热泵系统的开启、关闭以及调节冷量或热量的大小；水平换热系统4用于水平层的换热；垂直换热系统5用于垂直层的换热。The utility model is a ground source heat pump system that is connected and coordinated by a complete set of vertical heat exchange system 5, a complete set of horizontal heat exchange system 4 and heat exchange equipment 1, mainly including a set of indoor heat exchange equipment 1. After the exchanged heat or cold is processed, it is sent to the terminal system; a set of transmission pipeline 3 is used for the transmission and transfer of cold or heat; the valve 2 is used to control the opening and closing of the ground source heat pump system and adjust the cooling or The amount of heat; the horizontal heat exchange system 4 is used for the heat exchange of the horizontal layer; the vertical heat exchange system 5 is used for the heat exchange of the vertical layer.
在其运行的过程中，垂直换热系统5起到主要的换热或制冷作用，而水平换热系统4起到辅助作用。具体的讲，在夏季需要从地下获取冷量的时候，当垂直换热系统5获得的冷量不足时，由水平换热系统4进行补充；在冬季的时候，当垂直换热系统5获得的热量不足时，由水平换热系统4进行补充；本实际用新型的另一大作用是水平换热系统4可以作为垂直换热系统5的缓冲，因为在夏季工况下，当垂直换热系统5从地下换热获得冷量后，向地面以上机房等传送的时候，由于地表附近的温度非常高，虽然采取了一定的保温措施，但是冷量的损失量依然会很大，而水平换热系统4距离地表面较近，其温度处于垂直换热系统5运行的温度和地表温度之间，因此能够起到良好的缓冲作用，可以减少垂直换热系统5的冷量损失；在冬季，当垂直换热系统5从地下获得热量后，由于地表的温度非常低，垂直换热系统5的热量也会有相当的损失量，而水平换热系统4的运行温度处于垂直换热系统5运行温度和地表温度之间，也可以起到良好的缓冲作用，可以节省垂直换热系统5的热量不被浪费。During its operation, the vertical heat exchange system 5 plays a main role of heat exchange or refrigeration, while the horizontal heat exchange system 4 plays an auxiliary role. Specifically, when it is necessary to obtain cooling capacity from the ground in summer, when the cooling capacity obtained by the vertical heat exchange system 5 is insufficient, it is supplemented by the horizontal heat exchange system 4; in winter, when the cooling capacity obtained by the vertical heat exchange system 5 When the heat is insufficient, it will be supplemented by the horizontal heat exchange system 4; another major function of the new practical application is that the horizontal heat exchange system 4 can be used as a buffer for the vertical heat exchange system 5, because in summer conditions, when the vertical heat exchange system 5 After the cold energy obtained from the underground heat exchange is transferred to the computer room above the ground, because the temperature near the surface is very high, although certain insulation measures are taken, the loss of cold energy will still be large, while the horizontal heat exchange System 4 is closer to the ground surface, and its temperature is between the operating temperature of vertical heat exchange system 5 and the ground surface temperature, so it can play a good buffer role and can reduce the cooling loss of vertical heat exchange system 5; in winter, when After the vertical heat exchange system 5 obtains heat from the ground, due to the very low surface temperature, the heat of the vertical heat exchange system 5 will also have a considerable amount of heat loss, while the operating temperature of the horizontal heat exchange system 4 is at the operating temperature of the vertical heat exchange system 5 It can also play a good buffer role between the surface temperature and the surface temperature, and can save the heat of the vertical heat exchange system 5 from being wasted.
