Description
技术领域technical field
本实用新型属于温室太阳能高效利用领域，涉及一种温室集蓄热装置。The utility model belongs to the field of high-efficiency utilization of solar energy in greenhouses, and relates to a heat collection and storage device for greenhouses.
背景技术Background technique
为保证作物的正常生产，寒冷天气在广大地区进行农业生产时需对温室进行辅助供暖，目前燃煤供热系统(CFHs，coal fired heating system)和天然气供热系统(GFHs，gas fired heating system)是各国温室的主要供暖方式。由于温室设施内空间大、保温性较差等原因导致温室供暖耗能巨大。针对温室冬季夜间气温较低的问题，多年来，国内众多学者围绕如何提高温室对太阳能的利用，提高蓄、放热能力开展了大量研究。总体而言，大部分研究均是从增强土壤或墙体蓄热能力的思路出发。但这种被动的蓄、放热方式，其蓄放热能力的提升比较有限，夜间低温尤其是下半夜低温问题仍没有彻底解决。近年来，将白昼过余的太阳能以各种方式存储下来成为温室系统研究的新方向，例如塑料大棚中采用的地中热交换系统、温室中使用的能将热量存储在水箱和浅层土壤的聚烯烷树脂材料太阳能集热器、小型温室中使用的外置式的太阳能热水系统等，这些系统都能够在夜间温度较低时主动释放能量到温室中，逐渐成为温室领域研究热点。In order to ensure the normal production of crops, it is necessary to provide auxiliary heating to the greenhouse when agricultural production is carried out in a large area in cold weather. At present, coal-fired heating systems (CFHs, coal fired heating system) and natural gas heating systems (GFHs, gas fired heating system) It is the main heating method for greenhouses in various countries. Due to the large space and poor thermal insulation in the greenhouse facilities, the heating energy consumption of the greenhouse is huge. In response to the problem of low nighttime temperatures in greenhouses in winter, many domestic scholars have conducted a lot of research on how to improve the use of solar energy in greenhouses and improve the ability to store and release heat over the years. In general, most of the studies start from the idea of enhancing the heat storage capacity of soil or walls. However, this passive heat storage and release method has limited improvement in heat storage and release capacity, and the problem of low temperature at night, especially in the second half of the night, has not been completely solved. In recent years, storing excess solar energy in various ways has become a new direction of greenhouse system research, such as the ground heat exchange system used in plastic greenhouses, and the heat storage system used in greenhouses that can store heat in water tanks and shallow soils. Polyolefin resin material solar collectors, external solar water heating systems used in small greenhouses, etc., these systems can actively release energy into the greenhouse when the temperature is low at night, and have gradually become a research hotspot in the field of greenhouses.
对于当前的研究，中国专利CN106105905A公开了一种曲面涅尔透镜聚光与设施农业结合的太阳能集热系统。该系统利用整体滑移式聚光器与设施农业温室相结合，能将太阳光高度聚集，实现太阳能和农业种植技术互相补足利用。但该系统过于复杂，无法大面积推广。中国专利CN104838924A公开了一种温室大棚太阳能空气集热储热循环系统。该系统在温室大棚内地下铺一层隔热保温板，四周折起到地面，形成整体槽型，然后在隔热保温板上埋设集热导热管，将太阳能空气集热器的热量通过风机、风机管道、导风管送到地下集热管传给土壤层集热，夜间太阳能空气集热储热循环系统给地上棚内加温，该系统充分利用了太阳能，减少热量损失。For the current research, Chinese patent CN106105905A discloses a solar heat collection system that combines light concentrating with a curved Neel lens and facility agriculture. The system uses the combination of the overall sliding concentrator and the facility agricultural greenhouse, which can highly concentrate sunlight and realize the complementary utilization of solar energy and agricultural planting technology. But the system is too complex to scale up on a large scale. Chinese patent CN104838924A discloses a greenhouse solar air heat collection heat storage cycle system. In this system, a layer of thermal insulation board is laid underground in the greenhouse, and the surroundings are folded up to the ground to form an overall groove shape. Then, heat collecting and heat conducting pipes are buried on the thermal insulation board to transfer the heat of the solar air collector through the fan, The fan pipes and air guide pipes are sent to the underground heat collecting pipes to collect heat in the soil layer. At night, the solar air heat collection and heat storage circulation system heats the above-ground shed. This system makes full use of solar energy and reduces heat loss.
本实用新型主要针对温室在寒冷季节晴朗天气时，白天室内温度常常高于植物适宜生长的温度，而夜晚的温度又往往偏低的现象，在前人研究的基础上，提出了一种温室集蓄热装置，该装置创造性地将“表冷器”转变为集热器，把白天温室内的高温空气中的热量储存到水中，实现热量在时间、空间上的转移，提高太阳能的利用率，解决了冬季夜间温室温度过低影响作物正常生长的问题。The utility model mainly aims at the phenomenon that the indoor temperature of the greenhouse is often higher than the temperature suitable for plant growth during the day and the temperature of the night is often lower when the weather is sunny in the cold season. On the basis of previous studies, a greenhouse integrated Heat storage device, which creatively transforms the "surface cooler" into a heat collector, stores the heat in the high-temperature air in the greenhouse during the day into water, realizes the transfer of heat in time and space, and improves the utilization rate of solar energy. Solved the problem that the low temperature of the greenhouse at night in winter affects the normal growth of crops.

具体实施方式Detailed ways
本实用新型提供了一种太阳能高效利用领域的温室集蓄热装置，下面结合附图和实施例对本实用新型的具体实施方式作进一步的说明。The utility model provides a greenhouse heat storage device in the field of high-efficiency utilization of solar energy. The specific implementation of the utility model will be further described below in conjunction with the accompanying drawings and examples.
如图1所示，本实用新型所述的一种温室集蓄热装置，主要包括：“表冷器”1、空气循环风机2、水泵3、管路4、储热水池5和控制装置6。As shown in Figure 1, a greenhouse heat storage device described in the present invention mainly includes: "surface cooler" 1, air circulation fan 2, water pump 3, pipeline 4, heat storage pool 5 and control device 6 .
在日光温室的角落建一储热水池5，储热水池5在日光温室的地面以下。水泵3放置在水池内，将水泵3出水口连接供水管路4的一端；供水管路4的另一端与表冷器1的进水端连接；回水管路4与表冷器1的出水端连接，另一端伸入蓄水池5中。空气循环风机2安装在表冷器1的侧面，向表冷器送风。Build a hot water storage pool 5 at the corner of the solar greenhouse, and the hot water storage pool 5 is below the ground of the solar greenhouse. The water pump 3 is placed in the pool, and the outlet of the water pump 3 is connected to one end of the water supply pipeline 4; the other end of the water supply pipeline 4 is connected to the water inlet of the surface cooler 1; the return water pipeline 4 is connected to the water outlet of the surface cooler 1 Connect, and the other end stretches in the reservoir 5. The air circulation fan 2 is installed on the side of the surface cooler 1, and sends air to the surface cooler.
控制装置6主要由气温传感器、水温传感器和控制器等构成。The control device 6 is mainly composed of an air temperature sensor, a water temperature sensor, a controller and the like.
一般地，表冷器1安装在日光温室室内空间的高处位置，如屋脊下方或后坡处，高处空气的温度较高，不妨碍温室内作物的生长和工作人员的活动。Generally, the surface cooler 1 is installed at a high position in the indoor space of the solar greenhouse, such as below the roof ridge or at the back slope, where the air temperature is relatively high, which does not hinder the growth of crops and the activities of staff in the greenhouse.
该温室集蓄热装置的运行方法如下：The operation method of the greenhouse heat storage device is as follows:
(1)白天，当控制装置中的传感器检测到温室内的气温和储热水池中水温的差值高于设定值时，水泵和空气循环风机同时开启。一方面，温室内的高温空气在循环风机的作用下，将热量传递到“表冷器”的管路表面，使“表冷器”管路的温度升高；另一方面，在水泵作用下，低温的水流入到“表冷器”管路中，利用“表冷器”巨大的比表面积将热量迅速传递到水中。这样，就通过水的循环将温室内空气冗余的热能储存在了储热水池的水中，实现了热能的空间位置上的转移。(1) During the day, when the sensor in the control device detects that the difference between the air temperature in the greenhouse and the water temperature in the hot water storage pool is higher than the set value, the water pump and the air circulation fan are turned on at the same time. On the one hand, the high-temperature air in the greenhouse transfers heat to the surface of the pipeline of the "surface cooler" under the action of the circulating fan, so that the temperature of the pipeline of the "surface cooler" increases; on the other hand, under the action of the water pump , the low-temperature water flows into the "surface cooler" pipeline, and the heat is quickly transferred to the water by using the huge specific surface area of the "surface cooler". In this way, the redundant heat energy of the air in the greenhouse is stored in the water of the heat storage pool through the circulation of water, realizing the transfer of the spatial position of the heat energy.
(2)当控制装置中的传感器检测到温室内的气温与水温的差值低于设定值时，关闭循环风机和水泵，集蓄热过程停止。(2) When the sensor in the control device detects that the difference between the air temperature and the water temperature in the greenhouse is lower than the set value, the circulating fan and the water pump are turned off, and the heat storage process stops.
(3)通常，日光温室需要在11月份至翌年4月份以及特殊天气下进行加温，因此，本装置主要在11月至翌年4月运行。(3) Usually, the solar greenhouse needs to be heated from November to April of the next year and under special weather, so the device is mainly operated from November to April of the next year.
