In particular, there is a lack of a series of supporting programs tailored to local conditions, resulting in deviations and insufficiencies in the public's understanding of ground temperature air-conditioning. In summer, the average maximum temperature in June, July, and August in the south is above 30 degrees, which is quite muggy. Indoor heat insulation facilities in rural areas are not good, and if ordinary electric energy air conditioners are directly used, a considerable amount of electric energy will be consumed.

Preferably, a water level monitor 21 is provided on the pool wall of the foundation pool 10; the water level monitor 21 is connected to the water pump 15 through a circuit.

Preferably, the air inlet pipe 2 is provided with an air filter 23 .

Preferably, the insulated water tank 8 is arranged in the roof space 19 .

Preferably, there are multiple sprayers 4, which are evenly distributed between the lower end of the floor 20 and the diversion partitions 12, and the spraying direction of the sprayers 4 is vertically upward.

Preferably, the space formed between the flow guiding partitions 12 is in a zigzag shape.

Explanation of the principle of the utility model: the foundation of the building is first laid with reinforced concrete as the base 1 and the diversion partition 12, a certain space is left between the diversion partitions 12, a certain amount of water is injected, and prefabricated panels are laid on the diversion partition 12 Sealed into the floor 20. A fairly sufficient heat-exchanging air layer 11 has just been formed between the flow guide partition 12, the floor 20 and the water surface.

The water in the foundation pool 10 is pressurized into the insulated water tank 8 by the circulating water pump 22 and then sprayed out by the sprayer 4. After the outdoor air enters the space under the foundation through the air introduction pipe 2, it is mixed with the water mist sprayed by the sprayer 4 and blown out. Perform heat and mass exchange, during which there is latent heat and sensible heat exchange between air and water, mainly the latent heat exchange of water evaporation and heat absorption. At this time, the sprayer 4 sprays water mist at normal temperature into the air, and the process is isenthalpic humidification and cooling. Under the action of the diversion partition, the air is transported circuitously on the water surface, and the water surface can remove the unevaporated water mist in the air during the process. At this time, the air temperature is lower than the wet bulb temperature and higher than the air dew point temperature, and the heat and mass exchange of enthalpy reduction, humidification and cooling occurs on the water surface. Finally, the cold air is pumped into the room through the terminal cooling fan 18 in each air-conditioned room for cooling. Wherein the water surface is used as a place for heat and mass exchange, and the gap between the water surface and the floor 20 can achieve a good heat insulation effect on water, and the lower temperature of the surface soil layer 13 can reduce the water temperature. The diversion baffles set under the foundation provide sufficient heat exchange time for air and water, and can also save the useful space of the building without affecting the beauty of the building. Elevation below the floor 20 can well solve the problem of dwelling houses being affected with damp.

When the height of the water surface in the foundation pool 10 is lower than the required minimum water level, the water level detector 21 controls the water pump 15 to open and replenish the water in the foundation pool 10, and when the set maximum water level is reached, the water level detector 21 controls the water pump 15 to stop Supplement the water in the foundation pool 10.
