把太阳能长期贮存在地下到冬季用它给温室加温,这种节能蓄热温室,受到广泛重视.在地下蓄热的方法中,虽然有在温室地下较浅的地方(50厘米左右)埋设暖风管,通过吹风机使室内空气循环的方法,但它主要是短期循环放入的热能,因此蓄热量少,而且很大程度上容易受天气条件的影响.另外,夜间加温器运转时,凝结在暖风管上的水分在室内循环,容易导致室内空气湿度过大.
The long-term storage of solar energy in the ground to the winter to use it to heat the greenhouse, this energy-saving regenerative greenhouse, has been widely attention in the underground heat storage method, although in the greenhouse shallow ground (about 50 cm) buried warm Duct, the method of circulating indoor air with a hair dryer, but it is mainly the thermal energy into the short-term cycle, so less heat storage, and largely susceptible to weather conditions.In addition, the night warmer operation, condensation The warm water pipe on the indoor water circulation, easily lead to excessive indoor air humidity.
