Description

Technical Field

[0001] The utility model relates to the technical field of heating, ventilation and air conditioning, and in particular to a floor air supply system. Background Art

[0002] With the rapid development of today's society, people's living standards and quality are constantly improving, and they have higher requirements for their working environment. The HVAC system is developing rapidly, and its proportion in the entire project cost is increasing. The selection of a suitable HVAC system can not only improve the living environment, air quality, and physical comfort faster within a limited time, but also save energy.

[0003] Traditional HVAC systems usually use top air supply, which not only slows down the indoor temperature change, but also causes turbid air to settle on the ground floor, which is not easy to discharge and leads to low indoor air quality. During installation, workers need to work at high altitude, which increases the difficulty of construction and the risk of high-altitude work safety accidents. At the same time, it is not convenient for workers to clean and repair the HVAC system later. Therefore, we proposed a floor air supply system to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a floor air supply system to solve the problems of slow indoor temperature change, difficult discharge of polluted air deposition and great construction difficulty.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a floor air supply system, including a power terminal device and an air-conditioning main unit installed on the ground, one end of the power terminal device is connected to a return air duct, and the other end of the power terminal device is connected to an air supply duct, the return air duct and the air supply duct are both composed of fan coil units, the air supply duct is connected to an inlet pipe and a return pipe, the inlet pipe and the return pipe are connected in the air supply duct, the ends of the inlet pipe and the return pipe are connected to the air-conditioning main unit, the inlet pipe and the return pipe are both provided with a stop valve, the inlet pipe is provided with a regulating valve, the regulating valve is electrically connected to a thermostat, and a fixed component is provided between the inlet pipe and the return pipe.

[0006] The beneficial effects of this program are:

[0007] 1. By setting the air supply duct under the floor, cold air and hot air spread from the floor, which can quickly cool down or heat up the ground layer, so that people can quickly feel the change of indoor temperature, increasing the speed of indoor temperature change. At the same time, since the power terminal equipment, return air duct, air supply duct, water inlet pipe and return pipe are all set on the ground, there is no need for workers to perform high-altitude operations, which reduces the difficulty of construction.

[0008] 2. Traditional top-mounted HVAC usually sets both the supply air duct and the return air duct at the top. The upper circulation causes the turbid air to settle on the ground. It is difficult for the upper return air to discharge the turbid air on the ground, and it is basically in a stagnant state. In this solution, by setting the return air duct on the ground, it is beneficial to allow the turbid air to be continuously brought into circulation and more easily be taken out to the outdoors by the exhaust system, thereby improving the indoor air quality and the living environment.

[0009] Preferably, as an improvement, the fixing assembly includes an angle steel bracket and an asphalt wooden frame, the angle steel bracket is fixed to the ground, the asphalt wooden frame is fixedly installed on the outside of the angle steel bracket, and the asphalt wooden frame stacks and fixes the water inlet pipe and the water return pipe.

[0010] The beneficial effect is: fixing the water inlet pipe and the water return pipe to the outside of the angle steel bracket through the asphalt wooden frame can effectively save ground space, and make the installation of the water inlet pipe and the water return pipe more regular, which is convenient for the staff to construct it.

[0011] Preferably, as an improvement, the fan coil units are connected by a common plate flange, and an environmentally friendly sealant is used to stabilize the fan coil unit connections.

[0012] The beneficial effects are: the common plate flange connection is simple to operate, and the intermediate parts and auxiliary parts are directly engaged, which saves steel and simplifies the construction process. The environmentally friendly sealant further improves the sealing between fan coil units.

[0013] Preferably, as an improvement, the water inlet pipe and the water return pipe are both connected by hot-dip galvanized steel pipe threads.

[0014] The beneficial effects are: hot-dip galvanized steel pipes have strong corrosion resistance, can effectively resist corrosion, extend the service life of the water inlet pipe and the return pipe, and hot-dip galvanized steel pipes have high strength and rigidity, can withstand greater pressure and impact, and the threaded connection is tighter. At the same time, it is convenient for staff to connect them and the operation is simple.

[0015] Preferably, as an improvement, the outer sides of the return air duct, the supply air duct, the water inlet pipe and the return water pipe are all wrapped with rubber-plastic insulation material.

[0016] The beneficial effect is that wrapping the rubber and plastic insulation material on the outside can reduce the heat loss during the transmission of cold and heat sources and increase the cooling and heating effects.

[0017] Preferably, as an improvement, the return air duct and the supply air duct are connected to the power terminal equipment by a flexible joint.

[0018] The beneficial effect is that the soft joint can absorb vibrations through its own elasticity, preventing the power terminal equipment from transmitting vibrations to the return air duct and the air supply duct when working, thereby effectively reducing noise.

[0026] The specific implementation process is as follows:

[0027] During installation, according to the actual situation of the room, the power terminal device 1 and the fan coil unit 5 are placed at appropriate positions in the room, and the power terminal device 1 and the fan coil unit 5 are fixed to the ground by expansion bolts. The air conditioner host 2 is installed outdoors and fixed with concrete and channel steel. The fan coil units 5 are connected by common plate flanges, and the fan coil units 5 are directly fixed into appropriate air supply ducts 4 and return air ducts 3 by intermediary and auxiliary parts. The connection is stabilized with environmentally friendly sealant. The air supply duct 4, the return air duct 3 and the power terminal device 1 are fixedly connected by soft joints, and then the return water pipe 7 and the water supply pipe are connected.
