Generally speaking, the soil layer S under 5 meters of the ground is about 20°C to 24°C at room temperature. The soil layer S has excellent heat and cold storage capacity, and can be used as a thermodynamic cold source or heat source. The air (especially the air in the second chamber 20) performs cold and heat radiation. The two opposite ends of the condensation path 23 are respectively connected to the second air inlet channel 21 and the second air outlet channel 22. The condensation path 23 is provided with a plurality of cooling fins 26 to cool the air to an appropriate dew point temperature (normally the condensation temperature difference is It needs to be lower than the dry bulb temperature of the outside air by 6.5℃~7℃, so that the air reaches the dew point, and it is more able to completely condense in the second chamber), so that the temperature of the humidified air can be affected by the cold radiation of the soil layer S It drops below the dew point, so that the humidified air can condense in the condensation path 23 (for example, the wall surface of the condensation path 23).
