What Are The Maintenance Points For Air Handling Units And Rooftop Units?

Maintenance Points for Air Handling Units:

First, clean the filter regularly. The filter is an important part of the air handling unit, which can remove impurities in the air and ensure the cleanliness of the air. With the increase in the use of time, the filter will be gradually clogged, affecting the air circulation and filtration effect. Therefore, the filter needs to be cleaned or replaced regularly, and it is generally recommended that it be cleaned once every 1-3 months, depending on the environment in which it is used. Secondly, check the fan and motor. Fans and motors are the core components of air handling units, and their operating status directly affects the performance of the unit. Regularly check the operation of the fan and motor, including noise, vibration, temperature, etc., if there is any abnormality, they should be repaired or replaced in time. Furthermore, clean the heat exchanger. The heat exchanger plays the role of heating or cooling air in the air-handling unit, and it will accumulate dust and dirt after long-term use, which will affect the efficiency of heat exchange. It can be cleaned with professional cleaning agents, at least once a year. Also, check the electrical system. Regularly check the electrical system of the air handling unit, including wires, plugs, switches, etc., to ensure that the electrical connections are firm and free of leakage, short circuit and other safety hazards. Finally, conduct an overall inspection of the unit. Regularly conduct a comprehensive inspection of the air handling unit, including the shell, seals, piping, etc., to ensure that the unit has no leakage, air leakage and other problems, and at the same time, check the operating parameters of the unit, such as temperature, humidity, air volume, etc., and make timely adjustments if there is any abnormality.

Maintenance Points of Rooftop Unit:

For the maintenance of the roof machine, first of all, pay attention to waterproof and sun protection. As the rooftop machine is installed on the roof, it is easy to be eroded by rain and sunlight, so it needs to be well waterproof and sun protection measures. You can check the waterproof sealing of the rooftop machine regularly and repair it in time if it is damaged. At the same time, a sunshade can be installed for the rooftop unit to reduce the impact of direct sunlight on the unit. Next, clean the filter and heat exchanger regularly. Similar to air handling units, filters and heat exchangers of rooftop units need to be cleaned regularly to ensure air circulation and heat exchange efficiency. It is generally recommended to clean the filter every 1-2 months and the heat exchanger once a year. Further, check the fan and motor. Regularly check the operation of the fan and motor of the rooftop unit, and if there is any abnormal noise, vibration or high temperature, it should be repaired or replaced in time. Also, check the refrigeration system. The refrigeration system of the rooftop unit needs to be checked regularly, including pressure, temperature, refrigerant charge, etc., to ensure that the refrigeration system operates normally. If the cooling effect is found to be reduced, the refrigeration system should be promptly checked for leaks or other faults. Finally, conduct an overall inspection of the rooftop unit. Regularly conduct a comprehensive inspection of the rooftop unit, including the shell, bracket, piping, etc., to ensure that the unit is firmly installed and free of looseness, deformation and other problems. At the same time, check the operating parameters of the unit, such as temperature, humidity, airflow, etc., and make timely adjustments if there are any abnormalities.
