Abstract
An experimental study has been performed to investigate the correlation on compressor discharge temperature of capacity modulated system A/C in cooling mode. Indoor and outdoor temperatures, the cooling capacity, compressor discharge temperature and loading time are measured by the psychrometric calorimeter. The system is controlled by applying the scroll compressor operated by PWM valve and loading duty. With decreasing outdoor temperature, the cooling capacity increases. But, with decreasing indoor temperature, it decreases. According to the increase in outdoor temperature and loading duty, compressor discharge temperature increases. From these experimental data, the correlation on compressor discharge temperature is proposed. The correlation obtained from the present study is agreed with the experimental data within $3^{\circ}C$.
