What are the maintenance methods for hotel air conditioners?

The maintenance methods of hotel air conditioners are as follows:

1. For single coolers, when the air conditioner is not used in winter, it must be turned on once a month.

2. The condenser and evaporator should be cleaned regularly. The condenser of the outdoor unit should be protected from corrosion by external acidic, alkaline, and corrosive things. It goes without saying that the filter of the indoor unit should be cleaned. If the air quality is bad, wash it frequently, but be careful not to break the filter. Outdoor unit cleaning and maintenance. Step 1: Unplug the power plug and clean the case and chassis. The method is the same as cleaning the indoor unit panel. Step 2: Clean the inside of the machine, mainly cleaning the dirt on the heat exchanger. If dirt blocks the air path of the heat exchanger, it will affect the heat exchange, causing the cooling and heating effects to decrease; in severe cases, it will burn out the compressor, so cleaning it is particularly important. When cleaning, use a vacuum cleaner or a long-bristled soft brush to gently brush the cooling fins in the direction to remove attached dust and dirt. Step 3: Clean up. Check the rack screws. If they are loose, tighten them. If you find that the rack is severely corroded, replace them immediately. Use tweezers to carefully trim the collapsed heat exchange fins.

3. When the air conditioner is not in use, remember to protect it from dust.
