Abstract: To accomplish the drinking water, air cooling/heating, and hot water requirements for small-scale and domestic industries, a solar-powered heat pump polygeneration system is incorporated with the least floor area. It operates by extracting heat from a low-temperature source for heating or cooling. Key variables include airflow rate, temperature, and humidity. Using simulation tool, at 75% humidity and 40°C, the GOR and COP become 2.3 and 1.85. Additionally, the plant has an ECF of 2.2 and its cycle's ECF is 2.9. Furthermore, at 25°C and 75% humidity, the cycle and plant ECF were found to be 3.8 and 2.37, respectively.

Keywords: solar energy; heat pump; thermal pollution; desalination; polygeneration.
