How can I make my central air conditioning filtration equipment run more energy-efficiently?
How can I make my central air conditioning filtration equipment run more energy-efficiently?Where to start to make the use of equipment more energy efficientI. Low profile air speed design The so-called sectional airspeed is in the air treatment, air through the filter, or heating and cooling coil speed, in the current design, most engineers will be based on the so-called "experience" of the air filter design to 500 inches per minute, but such a design although a lot of time savings, but increased the operating costs This saves time but increases operating costs. In a low-profile design, the equipment can be designed to use a larger processor and smaller fan to reduce the air velocity, thus reducing energy consumption and design costs. At the same time, the pressure drop also determines the energy loss of the fan, and we all know that the pressure drop is directly proportional to the speed drop. In summary, we can learn that a larger size air filter and coil area consume less fan energy to use a smaller fan and motor, while a smaller fan adds less heat to the air and will reduce the difficulty of cooling. The thickness of the small coil is easier to clean and run well, so the temperature of the chilled water can be a little higher, and the equipment works better and lasts longer in the case of low-section air speed operation. II. Motor efficiency The operation of the motor consumes most of the electrical energy in the clean room, especially the continuously running motor, which consumes a huge amount of electricity every month. Our advice here is to use a high-quality, efficient motor that does not cost much but is much more efficient. We can minimize the load on the machine before changing the size of the motor and use variable speed drives to improve the efficiency of the operation when the output changes. III. Number of air changes The cleanliness of a clean room requires a certain amount of airflow to be maintained, where the flow rate is determined by the number of air changes per hour, which also determines the size, construction, and energy consumption when designing the fan. It is important to remember that reducing the air flow rate reduces the cost of consumption while maintaining cleanliness in the cleanroom. In other words, if the number of air changes is reduced by 20% the size of the fan can be reduced by 50%. IV. Dual temperature refrigeration cycle Chilling systems are generally designed to withstand very large loads, regardless of the frequency with which large loads occur. The temperature of the chilled water is determined by a small percentage of the extreme heat load of all the loads, a situation that can result in excess chilling capacity, especially if the load is insufficient, and the efficiency of the plant can easily be reduced. Therefore, when the temperature of the chilled water supplied is relatively low, the efficiency of the chiller will also be low. |
