Abstract

PURPOSE:To reduce heat resistance between earth and the heat exchanger by a method wherein the outer surface of the heat exchanger, buried in earth, is covered by a surrounding body and thermosetting synthetic resin, poured by pressure inbetween the outer surface of the heat exchanger and the surrounding body, is thermosetted. CONSTITUTION:The outer surface of the heat exchanger 1 is wrapped by the surrounding body 2, made of butyl rubber, ethylene propylene rubber or the like and having stretchability and flexibility, and the heat exchanger 1 is buried into the ground as it is wrapped by the surrounding body 2. Thereafter, the thermosetting synthetic resin 3, such as phenolic resin, epoxy resin or the like, is poured by pressure inbetween the surrounding body 2 and the outer surface of the heat exchanger 1, the opening 9 of the surrounding body 2 is closed and hot air (c) is blown into the heat exchanger 1 to thermoset forcibly the thermosetting resin 3. According to this method, a space between the heat exchanger 1 and earth 4 is filled due to the thermosetted thermosetting resin 3 and heat resistance is decreased, therefore, heat exchanger between the earth and the heat exchanger 1 may be effected uniformly and smoothly.

合の熱交換能力の継時的変化を示す曲線である。There were two types of underground heat exchange equipment (heat exchangers): the double-cylindrical thermal well type shown in Figure 1, and the round tube type shown in Figure 2. Since both are buried in the soil as they are, when the soil hardens due to rainwater or ground vibration after embedding, a space is created between the outer surface of the heat exchanger (1) and the soil (4) that can hold air. There was a problem in that the heat exchange efficiency of the heat exchanger (1) was reduced due to the adiabatic space. In other words, line A shown in Figure 6 is a curve showing the change in heat exchange capacity over time in an ideal state with no space between the heat exchanger (1) and the soil (4), and The line is a curve showing the change in heat exchange capacity over time in the case of a space obtained in a demonstration experiment.
