In the design of a commercial kitchen ventilation system, it is very important to maintain the capture efficiency of exhaust hoods and ensure smooth removal of heat, moisture, and odor. The capture efficiency is affected by the kitchen ventilation system and the cooking appliance usage condition. To identify an appropriate ventilation system design method for commercial kitchens in Japan, surveys were conducted as follows.
This paper explains how to enhance the energy performance of a chiller plant designed with chillers ofequal size or unequal size and having superior coefficient of performance (COP) at part load operation.A simulation study was carried out on an air-cooled centrifugal chiller plant serving an office building.Four design options with respect to the number and nominal capacity of chillers were investigated(OP1: 6 x 1124kW; OP2: 8 x 810kW; OP3: 4 x 1213kW + 2 x 810kW; OP4: 2 x 1350kW + 2 x 1107kW +2 x 801kW).
