一种温室热能采集与热能提升方法及系统Method and system for collecting and improving heat energy in a greenhouse

技术领域technical field

本发明涉及的技术领域为农业工程技术领域,具体地说,本发明涉及一种温室浅层土壤热量采集与加热的方法和系统。The technical field that the present invention relates to is agricultural engineering technical field, specifically, the present invention relates to a method and system for collecting and heating shallow soil heat in a greenhouse.

背景技术Background technique

日光温室虽然可以将太阳能收集起来积蓄热量,并在室内温度降低的时候释放热量,保证室内温度不会过低,但是当遭遇极端低温的时候温室内的温度还不足以保证植物可以正常生长,为了保证温室内植物在冬季能够正常生长,必须提供加热设备。现阶段日光温室中常用的加热方式有热水采暖、热风增温、电热采暖、火道加温。这些传统的加热方式能耗较大,而且还产生大量有害气体,对环境造成污染。Although solar greenhouses can collect solar energy to store heat and release heat when the indoor temperature drops to ensure that the indoor temperature will not be too low, but when encountering extreme low temperatures, the temperature in the greenhouse is not enough to ensure the normal growth of plants. To ensure that the plants in the greenhouse can grow normally in winter, heating equipment must be provided. At present, the commonly used heating methods in solar greenhouses include hot water heating, hot air heating, electric heating, and fire path heating. These traditional heating methods consume a lot of energy, and also produce a large amount of harmful gases, which pollute the environment.

热泵被认为是利用温室由于其自身的蓄热效应被认为是利用热泵最有效的设施之一,冬季通过温室的贮热技术可以增加水蓄积的热量,为夜间加温提供热能。传统水源热泵一般是利用地下水加热温室。地下水源热泵系统主要适用于地下水资源丰富、水位较浅且便于开采的地区。我国北方地区地下水温度范围常年在7℃~21℃之间。冬季利用地下水作为热源,通过热泵系统把水中的热量抽出向室内供暖,降温后的水再回灌到地下。冬季由于地下水温度高于室外大气温度并且不会像空气源热泵发生结霜情况,因此地下水源热泵系统效率也高于空气源热泵系统。地下水源热泵系统已在建筑中广泛应用,在设施农业中由于受到初期投资成本的制约,在温室中应用受到一定的限制。水源热泵系统中热量采集费用包括水质勘探费用和打井费用,约占整个系统成本的50%左右,因此,降低热量采集费用是降低整套装置投资成本的关键因素之一。The heat pump is considered to be one of the most effective facilities for utilizing the heat pump due to its own heat storage effect. In winter, the heat storage technology of the greenhouse can increase the heat accumulated in the water and provide heat for night heating. Traditional water source heat pumps generally use groundwater to heat greenhouses. The ground water source heat pump system is mainly suitable for areas with abundant ground water resources, shallow water level and easy exploitation. The groundwater temperature range in northern my country is between 7°C and 21°C all year round. In winter, groundwater is used as a heat source, and the heat in the water is pumped out through the heat pump system to heat the room, and the cooled water is refilled into the ground. In winter, the groundwater heat pump system is more efficient than the air source heat pump system because the groundwater temperature is higher than the outdoor atmospheric temperature and does not frost like the air source heat pump. The groundwater source heat pump system has been widely used in buildings, but due to the restriction of the initial investment cost in facility agriculture, its application in greenhouses is limited to a certain extent. Heat collection costs in water source heat pump systems include water quality exploration costs and well drilling costs, which account for about 50% of the entire system cost. Therefore, reducing heat collection costs is one of the key factors to reduce the investment cost of the entire device.
