How to quickly troubleshoot the cabinet air conditioner!
The scope of application of industrial air conditioners, how to maintain industrial air conditioners and increase service life on a daily basis?
Only need to remember a few points to increase the service life of cabinet air conditioners!

What are the benefits of cabinet air conditioning?
Electrical equipment usually heats up due to the effect of current during operation, and too high temperature will affect the service life and reliability of electrical components, and will cause premature aging of the insulation device, or reduce the insulation value, so that the resistance of some conductors becomes larger , Heat and burn. The cabinet air conditioner can reduce the temperature of the equipment, thereby increasing the service life of the equipment!

Common faults and elimination methods of cabinet air conditioners

The device does not start. The circuit is open or short circuit Check the circuit is open or short circuit, and repair the main power supply
Controller failure Replace controller
Internal fan does not start. Terminals are loose. Check whether the fan power terminals are loose.
Power failure Check whether the voltage of the input power is within the working range
The fan is stuck Check if any foreign objects are stuck in the fan
The external fan does not start. The terminals are loose. Check whether the fan power terminals are loose.
Power failure Check whether the voltage of the input power is within the working range
The fan is stuck Check if there is any difference
No energy saving/cooling demand Normal state when not cooling
Fan abnormal noise Fan bearing wear Replace the fan
Fan blade friction Check if there is any cable interference with fan blade
The compressor does not start, the circuit connection is loose, tighten the circuit connector
Power is not turned on Check the main power switch, and check whether the display interface shows "start"
Power failure Check whether the voltage of the DC power supply is within the working range
Compressor motor burned out
No cooling requirement Check the temperature display in the cabinet and the output status of the compressor in the operation interface
Stop delay Delay time for compressor interval start is 3 minutes
Compressor built-in protection Check if the compressor protector contacts are open
System high pressure protection The external ambient temperature is too high or the external circulation air volume is insufficient and check the condenser temperature
Poor cooling effect Insufficient external circulation air volume Clean up impurities entering the coil or air inlet

The scope of application of industrial air conditioners, how to maintain industrial air conditioners and increase service life on a daily basis?

What is the scope of application of industrial air conditioning? How should routine maintenance be maintained?

The industrial cabinet air conditioner is specially designed for the application in the field of communication. It cools the air of the electrical cabinet through two separate and isolated cycles inside and outside and dissipates the heat in the cabinet out of the cabinet through heat exchange, thereby solving the problem of outdoor communication cabinets and wireless outdoor. Heat dissipation problems such as cabinet base stations and battery cabinets. It provides an ideal temperature and humidity environment for various types of cabinets, and at the same time isolates dust and corrosive gases in the external environment, extending the service life of electrical components and improving the reliability of machine system operation. Suitable for electrical control box, communication, communication equipment, data processing box and heavy motor equipment control box, etc.

Daily maintenance
1. Wiring: visually check for looseness
2. Abnormal fan: Turn the fan to see if it rotates smoothly and whether there is abnormal noise
3. Drain pipe: visually check whether the drain pipe is dirty
4. Condenser: Check the cleanliness of the condenser and clean the condenser with compressed air
5. Fixing screw: check whether the fixing screw is firm, pay attention to strengthen fixing

Only need to remember a few points to increase the service life of cabinet air conditioners!

The cabinet air conditioner is specially designed for the application in the communication field. It cools the air of the electrical cabinet through two independent and isolated cycles inside and outside and dissipates the heat inside the cabinet out of the cabinet through heat exchange, thereby solving the problem of outdoor communication cabinets and wireless outdoor cabinets. Heat dissipation problems such as base stations and battery cabinets.
Summer is the peak season for the sale of cabinet air conditioners. In addition to looking at the quality of the cabinet air conditioner products, it is very important to maintain quality. Maintenance is also an essential part of the cabinet air conditioner. The cooling and heating effects of the cabinet air conditioner are closely related to the service life. Inseparable relationship. The following briefly introduces the precautions and maintenance tips for using cabinet air conditioners in daily life.

1. Maintenance Tips
1. The cabinet air conditioner uses the power saving method
Cabinet air conditioners are considered to be a large consumer of electricity in electrical appliances. Whether the cabinet air conditioner consumes electricity, the number of times the cabinet air conditioner is used when it is used is a very important factor. The current required when the cabinet air conditioner is started is relatively large, and the power consumption is relatively high, so the startup period is relatively power consuming. The average family can make good use of the timing function to make the cabinet air conditioner not work all night and maintain the indoor temperature. The general user starts from 5 pm and sets the operating time of 4-5 hours as much as possible to maintain the indoor temperature. Reduce indoor temperature rise caused by convection with outside air. A
2. The outer shell, interior and filter maintenance of the cabinet air conditioner
There are various partitions on the panel of the air-conditioning cabinet of the cabinet, which are easy to collect dust. You can clean it regularly with a soft leather, and use neutral soap not exceeding 40 ℃, but everyone must pay attention that you can not use volatile oil, gasoline and acids Chemical scrubbing. A
The maintenance method of the cabinet air conditioner. When the cabinet air conditioner is used for a long time, there will be a lot of dust and bad smell in the room, which directly affects the cooling effect of the cabinet air conditioner and the indoor environment. Therefore, long-term regular cleaning is necessary. The easy-to-use method is to clean the indoor heat exchanger, carefully remove the panel, scrub with a soft rag, and use a small brush to gently scrub the heat exchanger of the indoor unit, but note that because the heat sink is very thin aluminum The material is easily deformed after being stressed, so brush carefully to avoid abnormal operation of the cabinet air conditioner in the future. A
Indoor filter cleaning, if your filter is dirty, then the cooling effect of your cabinet air conditioner must not be very good, so you should regularly clean it to ensure the normal operation of the cabinet air conditioner.
