Commercial air conditioners are typically used in public places such as large shopping malls or shopping centers, where foot traffic is high. Therefore, the effect of the air conditioning is to ensure smooth air circulation and to regulate the temperature in response to fluctuating weather conditions. Next, Shanghai Yubang Electrical Equipment will analyze how to properly clean and maintain commercial air conditioners, as well as the best practices for combined cleaning and maintenance.

Step One

Commercial air conditioning systems primarily focus on the indoor unit during initial installation. When installing the indoor unit, it is crucial to ensure that the distance between the unit and the ceiling is no less than one centimeter to prevent vibration with the wall and ceiling during operation. Additionally, consider a 0.5% slope during installation, with the side connected to the condensate drain slightly lower to avoid water droplets inside the unit due to delayed condensate drainage.

Step Two

Upon completion of the indoor unit installation, the refrigerant copper pipes can be connected, which is an important step in commercial air conditioning installation. During the installation, attention should be given to: welding at the point of refrigerant copper pipe installation, where the copper pipe and the branch pipe are connected. It is essential to fill the copper pipe with nitrogen during the welding process to prevent contact with air, which could lead to carbon buildup inside the copper pipe and cause malfunctions in the compressor during operation. After welding, use high-pressure nitrogen to blow out any debris inside the pipe to maintain cleanliness. Additionally, nitrogen must be injected into the copper pipe for a pressure test, lasting 24 hours.
