Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning and ventilation, and in particular to a cross-floor pipeline layout structure and a ventilation system of a multi-connected central air conditioner. Background Art

[0002] With the development of the times, there are more and more high-rise buildings. Among them, medium and large multi-story buildings will use central air conditioning to ventilate and cool the entire building in the hot summer environment;

[0003] The prior art patent CN102112814B provides an air conditioning device that inhibits refrigerant from entering a living space and implements a refrigerant leakage countermeasure. The longitudinal pipes connect the heat source device and the relay unit across multiple floors; the horizontal pipes connect the relay unit and the indoor unit from the outside of the wall separating the indoor and outdoor of the air-conditioned space, so that the liquid secondary refrigerant flows on both sides of at least two pipes in a group, and the indoor unit performs ventilation and cooling treatment across floors in the room;

[0004] The prior art patent CN11597877 provides a return air cover plate connection structure, a cover plate assembly and an air-conditioning indoor unit, which solves the technical problem of low assembly efficiency of the return air cover plate in the prior art. The installation process is simple and convenient, and the assembly efficiency between the return air cover plate and the cover plate body of the air-conditioning indoor unit is improved. When it is necessary to switch the return air mode of the air-conditioning indoor unit, the setting of the return air cover plate connection structure makes the switching assembly process simple and efficient.

However, due to the large amount of lint and dust in the air, the central air-conditioning indoor unit only relies on the filter plate of the return air port when performing return air processing, and the filtering effect is poor and the function is single.

One side of the ozone generator 46 is fixedly connected to the delivery pipe 15 through an electric control valve. The electric control valve can prevent the condensed water delivered by the delivery pipe 15 from contaminating the ozone generator 46. The ozone gas generated by the ozone generator 46 can enter the closed cover 4 through the delivery pipe 15 and the contact ball 14, and then be blown into the air-conditioning indoor unit 2 and the indoor space. When the air-conditioning indoor unit 2 performs the indoor air purification operation, the circulating indoor air is disinfected with ozone to disinfect bacteria.

[0049] A ventilation system having the above-mentioned multi-connected central air-conditioning cross-floor pipeline layout structure comprises a power module, a temperature sensor module, and a PLC recording and control module.

[0050] When in use, the central air conditioner outdoor unit at the top of the building floor continuously delivers the refrigerated refrigerant to the central air conditioner refrigerant pipe 1 through the compressor, and the refrigerant is connected to the evaporators of several air conditioner indoor units 2 through the central air conditioner refrigerant pipe 1. At this time, the drive motor 7 is started, the drive shaft 6 drives the supply fan 5 to rotate, and the position of the return air network 11 is controlled. The air is blown to the evaporator of the air conditioner indoor unit 2 through the filter plate, the air inlet window 20, the air inlet area 23, the liquid drop tank 19, the treatment tank 12 and the two sides of the fan blade cover 8 in sequence, and the air at the temperature exchange port is blown into the room;

[0051] When the air passes through the filter plate of the return air network 11, preliminary indoor air dust filtration is performed. When the condensed water of the evaporator of the air conditioner indoor unit 2 is collected in the condensed water tray 3, the condensed water in the condensed water tray 3 is pumped and pressurized by the small liquid pump 39, enters the delivery pipe 15 from the pump liquid pipe 40, and then sprays to the water seepage hole 16 above the contact ball 14 through the delivery pipe 15 and the water delivery trough 18 of several lifting water pipes 17. Then, under the action of natural gravity, the liquid flowing out of the water seepage hole 16 adheres to the surface of the contact ball 14. When the drive shaft 6 rotates, the air entering the treatment tank 12 from the liquid trough 19 first contacts with the condensed water on the surface of the contact ball 14. At this time, the condensed water temperature is relatively low, which is beneficial to the cooling effect of the air, energy saving and environmental protection. At the same time, the condensed water adhered to the surface of the contact ball 14 can adsorb and process the dust that cannot be filtered by the filter plate;

[0052] The synchronous pipe shaft 13 is slowly rotated by the gear transmission speed control of the driving gear 43 and the speed gear set 42, and the contact efficiency between the surface of the contact ball 14 and the air is increased, and the condensed water is more easily coated on the surface of the contact ball 14. As the condensed water is continuously fed into the lifting water pipe 17, the liquid dripping from the surface of the contact ball 14 naturally drips into the liquid drop groove 19, and then falls into the receiving seat 21 through the guide of the conical guide plate 22, and then flows into the collection box 25 through the connecting elbow 24, and is discharged after being collected. During this period, the air from the air inlet window 20 enters. Under the shielding and guiding effect of the conical guide plate 22, the dripping water will not be discharged from the air inlet area 23, and will not affect the normal entry of air.

[0053] When there is a lot of dust and dirt adhered to the surface of the contact ball 14, the lifting push rod 34 pushes the synchronous plate 33 and the cleaning sealing ring 28 to lift up, and the cleaning scraper ring 29 contacts the contact ball 14. When the contact ball 14 rotates, the cleaning scraper ring 29 scrapes the dust-containing sewage on the surface of the contact ball 14 into the adapter groove 30 of the cleaning sealing ring 28, and then flows into the annular discharge groove 37 and the dirty liquid collection groove 36 from the outflow hole 31 for collection and discharge. When the cleaning sealing ring 28 is in the lowest state, the cleaning sealing ring 28 can block the annular discharge groove 37. At this time, air can only enter the closed cover 4 through the air inlet window 20;

[0054] When the air conditioner indoor unit 2 performs indoor air purification operation, the ozone gas generated by the ozone generator 46 can enter the closed cover 4 through the delivery pipe 15 and the contact ball 14, and then be blown into the air conditioner indoor unit 2 and the indoor space to ozone the circulating indoor air to disinfect bacteria.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
