Abstract

Achieving thermal comfort with minimum energy consumption is the main requirement in designing an air-conditioning system. This research study about the variable compressor speeds to increase energy efficiency with better temperature control. The usage of on/off controller consumes large energy as the compressor is working at the maximum speeds, and it turns on and off when it achieved the temperature setting, causing high-energy usage. Variable-speed compressor controller will constantly vary the compressor speed to reach the temperature setting. The experiment is done in a thermal environmental room for a controller system to implement the controller algorithms with temperature setting of 23 and 24°C with internal heat loads of 1000 W. Data acquisition system is implemented to monitor of the room temperature, energy consumption, energy saving and coefficient of performance. The proposed variable-speed compressor system indicates more energy savings with better temperature control compared to on/off controller system.
