Efficiency of System Integration:
In the general and traditional control system, because of the place where the temperature controller is installed or the largest capacity design on the system, the fan runs in fixed frequency. Thus, when the ambient temperature reaches the set temperature, there will still be too much cool air, resulting in the waste of energy. The temperature that is too low also makes the people in the environment feel uncomfortable. However, with Delta's human machine interface and temperature controller, you are able to control the temperature of your working environment. The handy interface allows you to set up your desired temperature precisely (to one digit after the decimal point), and by the PID operation in the temperature controller, you can modulate the openness of the valve as well as the wind volume, which not only helps maintain the constant temperature, but also reduces the consumption of chilled water and power for the water chiller. Therefore, with only very little expenditure on the materials and construction, you can work or live in a comfortable environment and save energy every day!

System Reform:
In theory, half of the motor running speed (reducing from 60Hz to 30Hz) requires only 1/8 of the energy. However, due to the CO 2 exhaled from the people in the environment, in experience, a normal air circulation requires the running speed of the motor at least at 30Hz.

The openness of the chilled water valve can modulate the volume of chilled water. If there are many water chillers in the system, you can also decide whether to remove some chillers by the PLC program in reducing the waste of energy.
