What are the Energy Saving Measures for Air Handling Units and Rooftop Units?

Energy saving measures for air handling units:

One is to optimise the air treatment process. Reasonably design the air duct and filter layout of the air handling unit to reduce air resistance and lower fan energy consumption. Adopt high-efficiency filters to reduce the resistance of the filter and reduce the operating power of the fan while ensuring the cleanliness of the air. Second, the use of intelligent control systems. Installing an intelligent control system can automatically adjust the operating parameters of the air handling unit, such as temperature, humidity, air volume, etc., according to changes in the indoor and outdoor environments to achieve energy-saving operation. For example, at night or when there are fewer people, the operating power of the unit is automatically reduced to save energy. Third, the use of renewable energy. Consideration can be given to the use of solar energy, geothermal energy and other renewable energy sources for heating or cooling in the air-handling unit to reduce dependence on traditional energy sources and reduce energy consumption. Fourth, regular maintenance. Regular cleaning of filters, heat exchangers and other components to maintain a good operating condition of the unit, improve heat transfer efficiency and reduce energy consumption. At the same time, timely maintenance of faulty parts to avoid energy waste due to equipment failure. Fifth, reasonable setting of indoor temperature and humidity. Reasonably set the indoor temperature and humidity according to the actual demand, to avoid over-regulation. In summer, set the temperature at about 26℃, and in winter, set it at about 20℃, which can ensure the comfort and reduce energy consumption at the same time.

Energy-saving measures for rooftop units:

Firstly, choose an energy efficient rooftop unit model. When purchasing a rooftop unit, choose a product with a high energy-efficiency ratio. The higher the energy-efficiency ratio, the higher the energy-use efficiency and the better the energy-saving effect. Secondly, optimise the installation location of the rooftop machine. Reasonably select the installation location of the rooftop unit to avoid direct sunlight and obstructed air outlets, improve the heat transfer efficiency of the unit, and reduce energy consumption. Further, adopt inverter technology. Inverter rooftop units can automatically adjust the operating frequency according to changes in indoor load to achieve energy-saving operation. When the load is low, reduce the operating frequency to reduce energy consumption; when the load is high, increase the operating frequency to ensure the cooling or heating effect. In addition, strengthen the heat insulation and heat preservation. The pipeline and shell of the rooftop machine are insulated to reduce heat loss and improve the efficiency of energy use. Finally, make reasonable use of natural ventilation. When the weather is suitable, natural ventilation can be used to reduce the indoor temperature, reduce the operating time of the rooftop unit, and achieve energy saving.
