Abstract

The invention discloses a central air-conditioning fan-coil circulation cleaning device, which relates to the technical field of fan-coil cleaning and includes a circulation pump, a delivery pipe, a cleaning liquid tank, a liquid outlet hose, a liquid inlet hose and a base plate; the circulation pump Fixed on the base plate; one end of the delivery pipe is connected to the outlet end of the circulation pump, the other end of the delivery pipe is connected to one end of the outlet hose; one end of the inlet hose is connected to the inlet end of the circulation pump; cleaning The liquid tank is arranged above the conveying pipe, which contains cleaning liquid, and the cleaning liquid tank is connected with the conveying pipe through a connecting pipe, an infusion valve is arranged on the connecting pipe, and casters are arranged at the bottom of the base plate; There is a hose fixing mechanism on it, including a driving mechanism, a guide rail, a moving horizontal frame, and a rotating pillar; a moving carrier is movable on the rotating pillar, and a snap-fit ​​socket is arranged on the moving carrier; the cleaning efficiency of the cleaning equipment of the present invention is High, no removal point, more thorough cleaning, easy to use and disassemble the hose.

Description

technical field [0001] The invention relates to the field of air-conditioning water system cleaning, in particular to a central air-conditioning fan coil circulation cleaning device. Background technique [0002] The fan-coil air-conditioning system is a unit composed of fans, coils (small surface heat exchangers), filters, etc. As the terminal device of the air-conditioning system, it is distributed in each air-conditioned room and can independently control the air The cold and hot water required for air treatment is prepared centrally by the air conditioner room and provided to each fan coil unit through the water supply system. The fan circulates a part of the indoor air (filtered by an air filter and cooled by the coil or After heating), it is directly sent into the room to achieve the purpose of regulating the temperature and humidity of the indoor air. The fresh air required by the room can enter the room through the infiltration of doors and windows or directly throu...

Problems solved by technology

[0003] However, after a period of operation of the coil unit in the air-conditioning water system, the inner wall of the coil will be oxidized and the sediment will accumulate and cover, thereby reducing the heat transfer effect of the coil, and the reduction rate of this effect can generally reach more than 30%. Therefore, this is It will cause the energy to be unable to be effectively transported, and there is a defect that the energy saving effect is poor

The original traditional cleaning and maintenance method is to remove the water inlet and outlet of the indoor unit and connect the water pipe for flushing. This method will make the work difficult for the operators, and it will easily cause leaks after dismantling and restoration. There will be installation quality problems or material problems, which may cause damage to the pipe fittings and equipment when the connection is removed, which further increases the difficulty of work and maintenance time. In addition, the above-mentioned method has the problem of incomplete cleaning, which only rinses the surface with water Dirt is difficult to remove
