一、地下热交换试温室的结构及其施工方法试验用地下热交换式温室的概要如图所示,由送风机、送风装置、热交换管道及风机控制器等部分组成。白天晒热的温室内空气不排放,由送风机经管道贮存于管道四周的土壤中,到夜间再把这部分热能由送风机释放到温室内,以提高温室的温度。在此为把这种形式的温室用于栽培长年生长的葡萄,关键是如何布置热交换管道的问题。为了提高蓄热量,要求地下热交换管道 I. Structure and Construction Method of Underground Heat Exchange Test Greenhouse The outline of the underground heat exchange greenhouse used in the test is shown in the figure. It is composed of a blower, an air supply device, a heat exchange pipe and a fan controller. During the daytime, the air in the hot greenhouse does not discharge. It is stored in the soil around the pipeline by a blower and is sent to the greenhouse at night by the blower to increase the temperature of the greenhouse. Here, the key to using this type of greenhouse for growing grapes grown for many years is how to arrange heat exchange pipes. In order to increase heat storage, underground heat exchange pipes are required
