Make the temperature of the room uniform, without the feeling of blowing, and have the advantages of comfort.

A floor cooling and heating air-conditioning system with a fresh air replacement device, characterized in that:

A) The air system of the fresh air replacement device is to have an air supply port on the wall on one side of the room, one end of the air supply duct is connected to the air supply opening, and the other end of the air supply duct is connected with the dehumidifier and the heat recovery device in turn, The nozzle extends to the outside; there is an exhaust outlet on the wall on the other side of the room, one end of the exhaust duct is connected to the exhaust outlet, the other end of the exhaust duct is connected to the heat recovery device, and the nozzle extends outside;

B) The automatic control system of the fresh air replacement device is connected by a central controller with a humidity controller, a carbon dioxide controller, a dehumidifier actuator, and a heat recovery device actuator.

The air supply and exhaust form adopts the air supply from the lower part and the return air from the upper part.

The advantages and positive effects of the utility model are: the humidity of the fresh air is reduced after passing through the dehumidifier, and the air supply adopts the form of sending the air up and down, which is beneficial to control the floor condensation; the air system has a remarkable energy-saving effect due to the heat recovery device; The system and the water system are independent of each other, so the independent control of temperature and humidity can be realized, and the energy saving effect can be further achieved; due to the introduction of the fresh air system, the indoor air quality can be achieved throughout the year; at the same time, the room temperature is uniform and has the advantages of comfort; Since the control system adopts distributed control, it is easy to use.
