CLVS includes equipment with constant load and varying hours-of-use, as depicted in Figure below. There are two bins in the load frequency distribution; however, the total number of hours in each bin is unknown.
Examples of equipment with CLVS operating characteristics include:
2. Lighting under occupancy-sensor control
3. Constant-speed cooling tower fan operation (schedule varies with temperature)
4. Hot water or chilled water pumping, no VFD (schedule varies with boiler/chiller
5. Auto factory paint-shop exhaust fans
