Performance evaluation of conventional chiller systems
- San Diego State Univ., CA (United States). Dept. of Mechanical Engineering
This article describes an optimization technique to reduce chiller energy usage by evaluating energy saving strategies. In most commercial buildings and industrial plants, HVAC systems are the largest energy consumers and offer the owners significant potential for savings. Chiller machines are also of interest to utility companies because they operate during cooling times that overlap peak hours of warmer climate zones, thereby contributing to peak energy demands. The key performance parameter in chiller analysis is the kW/ton of refrigeration, which is the ratio of the amount of electrical energy consumed relative to the amount of cooling energy delivers. To obtain the kW/ton refrigeration for a chiller, the electric power consumption (kW) of the compressor should be measured, or calculated if the instantaneous current and voltage are known.
