Central air-conditioning energy control air conditioning unit is the intelligent way to building the most energy-consuming devices in their different operating mode, the following aspects should be considered energy-efficient air conditioning unit: 1. condition year-round operation of the system is automatically switched according to outdoor weather conditions and air conditioning systems The different requirements of different structures and processes of the conversion conditions were small, generally as a conversion value judgments baking conditions by adjusting parameters to achieve the air conditioning running. 2. Select the PID controller parameters reasonable parameters of each loop, so that it has a good response performance, or choose from a variety of advanced control algorithms to improve the performance of the control system. Avoid the adverse effects of the control loop is always in the process of constantly adjust or slow response, not only a waste of energy and influence the life of the actuator. 3. Multi-Class with the control of some system has a central air conditioning unit outside the room with a reheat coil (especially air conditioning technology) to achieve individually adjustable. In this case, a reasonable choice of control method and with the relationship between supply air temperature control, to prevent the central air supply temperature is too low, resulting in waste of energy reheating room phenomenon. 4. Use high-quality indoor air temperature sensor is adjusted every 1 ℃ difference consumes a lot of energy, high-precision sensor selection, energy efficiency is much greater than the price of the sensor. 5. The temperature setpoint should be automatically adjusted with the outdoor temperature for the comfort of air conditioning systems, can be increased in the summer with the outdoor temperature, appropriately increasing the setpoint temperature, reducing indoor and outdoor temperature difference, both guarantors of comfort requirements, but also achieve energy savings. Similar control is also suitable for winter.
