WebAn air-source heat pump system uses electricity to power a compressor and transfer heat using the refrigeration cycle. In winter, it transfers heat indoors; in summer, it transfers heat outdoors. Think of it as an air conditioner that can also work in reverse. The system may distribute hot or cold air using your existing ductwork. WebTheir configuration uses organic Rankine cycle (ORC), LiBr-H2O operated refrigeration, and a process heat exchanger. Their investigation reveals that employment of absorption chiller and a reduction in exergy losses of the solar collector significantly enhance the performance of system.
