Earth to air heat exchanger
WebJul 10, 2024 · A blower is situated at the entrance of the earth tube system to move the air through the piped system and into the home. By burying a long portion of plastic tube underneath the ground, the cool temperature of the soil is exchanged with the warmer air that is entering the tube. WebThe air temperature at the outlet of the exchanger is lower by more than 5 °C in extreme cases, so depending on the purpose and the use of the heat pump (e.g., in the sphere of human comfort), it may be a problem, and an analysis should be performed to obtain the optimal air and technical parameters of the dehumidifier (e.g., electricity ...
