为解决连栋温室冬季能耗大、费用高的问题，进行了采用地中热交换系统部分代替燃煤的贮热加温试验。测定了空气和管道周围土壤贮、放热前后的温度等参数变化，系统在夜间加温能力可达加温热流量６０Ｗ／ｍ２，可有效保证夜间室内气温高于室外１１℃以上。 In order to solve the problem of large energy consumption and high cost of winter greenhouse in multi-span greenhouse, the heat storage and heating test was carried out, which replaced part of coal with the medium heat exchange system. The change of soil storage and exothermic temperature before and after the air and pipelines were measured. The system can heat up to 60W / m2 at night, which can effectively ensure that the indoor temperature is above 11 ℃ at night.
