System connection, the sub-collector system is connected with the buried pipe system; the cold and heat sources are connected with the temperature and humidity control system.

The composite air conditioning system consists of two relatively independent systems: the ground radiation cooling and heating system and the displacement ventilation system, and their respective cold and heat sources are also relatively independent. The displacement ventilation system appears in the form of a special unit, the fresh air and part of the return air are mixed, cooled (heated) by the cold and heat source, and sent into the room by the fan through the buried air pipe and the air outlet at the lower part of the room. In addition to providing a certain amount of fresh air, It can also remove indoor residual humidity and provide a certain amount of cold (heat). The ground radiation heating and cooling system is composed of cold and heat sources, sub-collectors, and buried pipe systems. The cold and heat sources provide cold (hot) water to cool (heat) the ground, thereby providing cold (heat) to eliminate indoor radiant heat gain (Supplementary heat deficiency), and directly conduct radiant heat exchange with the human body. The composite system controls the temperature of hot and cold water, fresh air volume, indoor temperature and humidity and prevents condensation on the ground through the temperature and humidity control device.

1. The cold and heat source provides low-temperature hot water (not exceeding 60°C) or medium and low-temperature cold water (5-20°C). The cold and heat source equipment can be heat pump cold and hot water units, various chillers, coal, gas, and oil Or electric boilers, urban central hot water supply, solar energy, underground (deep well) cold and hot water, etc.

2. The sub-collector system diverts the cold and hot water provided by the cold and heat sources. After being pressurized by the water pump, it is supplied to the buried pipeline for cooling and heating to the ground. After that, it is sent back to the cold and heat source through the water collector to cool down or heat again. And so on and on.

3. The buried pipeline system uses the energy provided by cold and hot water to regulate the temperature of the human body and the building in the form of radiation, and further adjust the indoor air temperature and humidity on this basis.

4. The displacement ventilation system includes traditional direct expansion air treatment equipment, which can cool, heat and dehumidify the air.

5. The air after the above treatment is pressurized by the fan and sent into the air duct buried under the ground, and the cool (or warm) fresh air is sent into the room through the air supply port installed at the foot of the equipment room to adjust the indoor air temperature and humidity. , prevent condensation on the floor, and provide a certain amount of cooling (or heat) and fresh air.

6. There are automatic control devices in the diverter system and the replacement ventilation system. The temperature of cold and hot water is controlled through sensors and corresponding control software, and the indoor temperature and humidity are adjusted, so that each circuit can be personalized. The automatic control device of the displacement ventilation system also ensures that the ground does not condense.

The working principle of the utility model is: this composite air-conditioning system uses low-temperature hot water (no more than 60°C) or medium-low temperature cold water (5°C-20°C) as the medium, through the heat exchange tubes buried under the floor Heating or cooling the floor, so as to radiate energy evenly to the room, and achieve the purpose of regulating the indoor air temperature. At the same time, the composite air conditioning system sends warm or cool fresh air to the room to adjust the air temperature and humidity, prevent condensation and provide a certain amount of cooling, heat and fresh air. This composite air-conditioning system has the advantages of saving energy, uniform heat exchange, providing fresh air, saving room area, no feeling of blowing, and good human comfort.

Low-temperature floor radiation heating and cooling use the ground in the building as the medium to heat and cool the building in the form of floor radiation. Since the radiant surface area is basically the same as the indoor usable area, it can evenly supply heat and cool to all places, and the indoor temperature is uniform. It is characterized by high comfort, uniform temperature field and good hygienic conditions.
