The "Five Constant Systems" include constant temperature, humidity, oxygen, quietness, and cleanliness. Current centralized air conditioning systems, which simultaneously heat and ventilate, produce a certain amount of heat in the air they release. However, these systems lack heat recovery capabilities, resulting in wasted heat in the exhaust air. Utility Model Content

The cooperation of the fresh air dehumidifier and the ventilation fan completes the exchange of indoor and outdoor air and reduces the indoor air humidity. The ventilation fan discharges the high-temperature air in the room into the exhaust pipe. The cooling and heating air source heat pump uses the high-temperature air discharged into the exhaust pipe and the outside air to heat the liquid refrigerant, and finally achieves the secondary utilization of the indoor hot air discharged to the outside, thereby achieving the purpose of heat recovery and reuse.

[0007] Furthermore, a water heat exchanger is provided in the water tank, and the cooling and heating air source heat pump is connected to the water heat exchanger.

[0010] Furthermore, the heat exchange element also includes a return pipe, one end of which is connected to the water tank, and the other end of the return pipe is connected to a third insulation manifold and a fourth insulation manifold. The third insulation manifold is connected to several of the ceiling radiation panels, and the fourth insulation manifold is connected to several of the floor radiation panels.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the ceiling radiant panels and the floor radiant panels are used to exchange heat between the moisture and the indoor environment to achieve a cooling or heating effect. At the same time, the ceiling radiant panels and the floor radiant panels are installed in each room in the room to achieve a cooling or heating effect in each room.

[0014] Furthermore, the water inlet pipe is also connected to an exhaust valve.

[0015] The beneficial effect of adopting the above further solution is that the gas contained in the moisture is discharged through the exhaust valve.
