Daily maintenance of the fresh air system mainly includes the following aspects:
● Cleaning the air outlet and filter: The filter of the fresh air system generally needs to be cleaned every 3-6 months, and the specific time depends on the local air quality. If it exceeds this time, the filter may be full of dust, and even mosquito corpses may appear, affecting the fresh air effect. Regular cleaning of the air inlet and outlet and the filter can effectively avoid secondary pollution and maintain the exhaust rate. The filter is divided into washable and non-washable. The washable filter can be cleaned according to the instructions, while the non-washable filter such as the HEPA filter needs to be replaced regularly.
● Fresh air host maintenance: When the fresh air system has been running for a period of time, if the wind speed drops or the noise becomes louder, there may be foreign matter inside the host. At this time, professional personnel are required to check and maintain to ensure that there is no foreign matter inside the fan, and observe the wind speed and noise to ensure the normal operation of the machine.
● Pipe cleaning and maintenance: The fresh air system will inhale a lot of dust and particles during operation. These pollutants will not only be deposited on the filter, but also attached to the inner wall of the pipe. If not cleaned for a long time, these dirt will not only affect the normal operation of the fresh air system, but also breed harmful substances such as bacteria and viruses, affecting the indoor air quality. Therefore, regular cleaning and maintenance of the pipes is a key step to ensure the efficient operation of the fresh air system.
● Air tightness check: The decline in air tightness is a common cause of insufficient air volume in the fresh air system. Long-term operation may cause loose parts and pipes, resulting in air leakage. Regular inspection and maintenance of the air tightness of the equipment can effectively improve the fresh air effect.
● Control panel maintenance: The control panel of the fresh air system is a precision electrical component. Long-term use will absorb a lot of dust and moisture, which may easily cause the control panel to fail or components to be damaged. Users should pay attention to humid weather during use, avoid touching the control panel directly with wet hands, and keep the control panel clean and dry.
● Maintenance of other components: For example, the cleaning and maintenance of the full heat exchanger also needs to be carried out regularly. The heat exchanger core needs to be cleaned or replaced regularly to ensure its efficient operation.
