Abstract

In this paper, several capacity-control schemes for conventional air-conditioning systems are discussed. An inverter-driven, variable-speed air-conditioner (VSAC), which allows continuous adjustment of system capacity, is investigated from an energy-conservation standpoint. Energy savings are estimated for a 100-m² residence in Dhahran equipped with a 17.6-kW, fixed-speed air-conditioner (FSAC). The simulated VSAC is driven by three different power sources. The use of a sine-wave motor-generator set, which produces the highest motor efficiency as a function of motor speed, will save 29% of the 20,000 kWh consumed by the FSAC, which agrees within 5% of the annual measured. Pulse-width-modulated (PWM) and six-step inverter systems will provide energy savings of 19 and 23%, respectively. Simulation results indicate that VSACs will operate for 5500 h, while the fixed-speed system will run for 3200 h annually.
