Abstracts: In the ETHE, the pipe is buried in the earth at a depth of 2 to 3 m. Then the ambient air is passed out through this pipe by the blower or any other equipment. There is a difference between the temperature of ambient air and earth clay. Due to this temperature difference, the heat transfer will be take place between the air and the clay. Now, at the outlet we can get the conditioned air as per our requirement.
