HPSIM

Detailed, fundamentals-based, steady-state simulation model of an air-to-air heat pump operating on the vapor-compression-cycle principle and charged with single-component refrigerant. HPSIM (Heat Pump SIMulation) includes tube-by-tube modeling of plate-fin air-to-refrigerant heat exchangers.
