At the same time, the return pump also sends the room-temperature coolant in the heat exchange tubes back to the storage tank through a return pipe on the other side. This cycle lowers the temperature of the heat exchange tubes, allowing outside air to come into contact with the positioned heat exchange tubes and cool down before entering the chamber. This process cools the agricultural products inside the chamber, preventing them from rotting and spoiling. Attached Figure Description
