What maintenance measures should we take to prevent the performance decline of explosion-proof air conditioners?

Mar 11,2019

We all know that explosion-proof air conditioners are a type of explosion-proof electrical equipment, with working environments classified into high temperature, low temperature, ultra-high temperature, and ultra-low temperature. Explosion-proof air conditioners are mainly used for cooling and heating in flammable and explosive environments such as petroleum, chemical industries, military units, oil depots, and offshore oil platforms. The appearance and usage of explosion-proof air conditioners are similar to those of ordinary air conditioners. However, in our daily lives, it is very important to maintain and service explosion-proof air conditioners to prevent a decline in performance and extend their service life. Let's take a look at the following points: 1. Regularly clean the air filter. Generally, after 2 to 3 weeks of use, the air filter should be cleaned once. When cleaning, pull the handle of the filter to remove it from the back of the panel, use a vacuum cleaner to suck out the dust from the filter mesh, and then wash it with clean water below 40°C. If there are oily substances, it can be cleaned in soapy water or a neutral detergent solution, then rinsed with clean water, and completely dried before reinstalling it back onto the explosion-proof air conditioner. Clean the panel and casing. Regularly wipe off dust and dirt from the panel and casing with a soft cloth. If it is too dirty, you can use a soft cloth dipped in soapy water or wipe with warm water below 45°C, then dry it with a soft cloth. Avoid using gasoline, kerosene, or chemical agents for cleaning. 2. Regularly clean the dust from the condenser fins. To prevent excessive dust accumulation on the air conditioner's condenser, which can affect the heat exchange capability of the explosion-proof air conditioner, the fins of the condenser should be cleaned with a vacuum cleaner or a portable blower about once a month to facilitate heat dissipation. For explosion-proof heat pump air conditioners, during snowy days in winter, snow accumulation around the unit should be promptly cleared to avoid affecting its working efficiency. When the air conditioner will not be used for more than a month, it should be run in a dry weather for about 2 hours to ventilate and dry the inside of the air conditioner before unplugging the power supply. 3. Before starting the explosion-proof air conditioner after a long shutdown, check the following items: 1. Check if the ground wire is broken or properly connected. 2. Check if the air filter is properly installed. 3. Check if the power supply is properly connected; if not, plug it in.
