Description

A cleaning method and system for a central air-conditioning surface cooler that can be cleaned automatically

technical field

The invention relates to a cleaning method and system for central air-conditioning components, in particular to a cleaning method and system for a surface cooler. In particular, it relates to a device that has been integrated with a cleaning device and a surface cooler to form an integrated device.

Background technique

In the central air-conditioning system of buildings in the prior art, a lot of dust and dirt will accumulate on the fins of the surface cooler during the use of the air handling unit, resulting in a decrease in the heat transfer efficiency of the surface cooler, a decrease in air volume, and an increase in noise, resulting in Central air conditioning operating costs increase.

At the same time, the dirt on the surface of the surface cooler is easy to breed bacteria, and there is a hidden danger of spreading diseases to the confined space, which poses a great threat to public health.

In order to ensure the normal use of the central air conditioner, the surface cooler needs to be cleaned regularly to remove dust and dirt. At present, the cleaning method for the surface cooler of the central air conditioner is mainly to open the maintenance door of the air handling unit after the air conditioner is shut down. Spray the cleaning agent on the surface cooler, and after a few minutes, use a high-pressure water gun or compressed air to perform high-pressure flushing on the surface cooler. Because the air handling unit is generally installed in the ceiling, the installation is scattered, resulting in a large workload for cleaning the surface cooler, and it is difficult to clean the surface cooler frequently.

And because the surface cooler is difficult to clean, in order to save costs, some central air-conditioning units have never cleaned it since using the central air conditioner, resulting in dust accumulation in the surface cooler, lower heat transfer efficiency, and pathogenic microorganisms such as bacteria and fungi.

In order to solve the above problems, there is already a Chinese invention patent No. 02249055.8, which discloses a solution named "a fan coil unit". The solution is mainly to arrange a cleaning device located near the heat exchanger. The cleaning device includes a detergent The detergent in the detergent box is sprayed on the fins of the heat exchanger through a shower device, so as to clean the dirt on the fins.

However, due to the insufficient water pressure in this method, it is difficult to remove the dirt with strong adhesion.

Furthermore, No. 200510046355.5 Chinese invention patent application discloses a technical solution called "A Method and Equipment for Dust Removal, Disinfection and Cleaning of Air-Conditioners". Clean the fan coils and air ducts of different central air conditioners. But the car is too high for the installation site, and the central air conditioner that the vehicle is difficult to reach is powerless.

In addition, the 97200879.9 Chinese invention patent discloses a technical solution called "Fan Coil Air Conditioner Coil Cleaning Device". The hose, in which the nozzle and the water baffle move synchronously on the guide rail, and the nozzle sprays out high-pressure water to clean the coil.

The shortcoming of this scheme is that one is that all parts to be moved must be manually pushed and pulled, and the operation must be manually operated. It is difficult to operate in a narrow and inconvenient position at the installation site; Waste a lot of water resources.

In summary, it is necessary to develop a convenient and practical automatic cleaning device for surface coolers.

The working principle of the present invention is: when the surface cooler 1 of the air handling unit needs to be cleaned, the intelligent control unit 10 is opened, the cleaning agent supply valve 55 is opened, the cleaning agent is injected into the cleaning liquid reconciliation container 52, the cleaning agent supply valve 55 is closed, and then Open the clear water valve 53, clear water enters the cleaning liquid reconciliation container 52 by the water outlet pipe 3, and further, an agitator 58 can be set to make the cleaning agent and water fully mix in the cleaning liquid reconciliation container 52 and then flow into the shower container 51. The container micropore 511 at the bottom of the shower liquid container 51 flows out and showers on the fins of the surface cooler 1 .

Further, a cleaning liquid valve 59 is set, and it is turned off and on in good time. When it is turned off, it waits for the cleaning agent and clear water to be fully mixed in the cleaning liquid mixing container 52. When it is opened, the cleaning liquid is filled with the shower liquid container in a short time. 51, instead of flowing out slowly, only flow on the fin near the cleaning liquid reconciliation container 52.

The time is controlled by the intelligent control unit 10, and the cleaning solution disperses and peels the insoluble scale and biological slime adhering to the fins, and the sewage flows into the waste water container 2 and is discharged from the drain pipe.

After the cleaning solution is completely sprinkled on the fins of the surface cooler 1, the clean water valve 53 is closed.

Also can be provided with a high-pressure valve 65, in the working process, open high-pressure valve 65, the high-pressure water in the water inlet pipe 4 shown in Fig. On the surface cooler 1 fin.

Rotate the toothed pulley 69 to drive the sliding device 66 at the upper and lower ends of the water nozzle assembly 61 to move back and forth along the water nozzle assembly guide rail 67. In this process, the moving track of the water nozzle assembly 61 can be monitored by the encoder.

The water curtain sprayed by the water nozzle 62 crosses the fins of the entire surface cooler 1 to wash the dust on the fins, and the water passing through the surface cooler 1 is collected by the waste water container 2 and then discharged by the drain pipe.

In the best way, since the water nozzle assembly 61 and the high-pressure hose 64 are connected using a universal joint 63, the high-pressure hose 64 can be bent freely according to the moving position of the water nozzle assembly 61, without affecting the spray nozzle.

After the high-pressure water pump 81 stops spraying water, the sewage outlet valve 57 is closed simultaneously, and some remaining Water stays at the transparent window, if it is dirty water, the light transmittance is low, the signal voltage sensed by the photoelectric sensor is also low, and the digital signal value output by the A/D converter 87 is also small. At this time, it shows that the surface cooler 1 has not been cleaned.

If it is clean water, the light transmittance is high, the signal voltage sensed by the photoelectric sensor is also high, and the value of the digital signal output by the A/D converter 87 is also large. Now, it shows that the surface cooler 1 has been cleaned.

This judging process is completed by the intelligent control unit 10 calling the cleaning judging module 89, and the judging result is used to determine whether to repeat the cleaning process.

Another purpose of the present invention is that when the relative humidity of the indoor air is very low, the clear water valve 53 can be opened, the water flows into the shower container 51, and the water is sprinkled on the surface cooler 1 through the micropores 511 of the bottom container of the shower container 51. On the fins, it can achieve the functions of humidification and cooling.

This function can be realized manually, also can be controlled by intelligent control unit 10, realizes automatically.

The invention is easy to manufacture, low in cost and convenient to install, can replace the surface cooler 1 of the air handling unit for manual cleaning, makes the surface cooler 1 work at high efficiency for a long time, reduces energy consumption of the central air conditioner, saves operation and maintenance costs, and can prevent surface cooling The device 1 breeds bacteria, has a broad market prospect, and is beneficial to popularization and application.

The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be assumed that the specific implementation of the present invention is limited to these descriptions. For those of ordinary skill in the technical field of the present invention, without departing from the concept of the present invention, some simple deduction or replacement can be made, which should be regarded as belonging to the protection scope of the present invention.
