An innovative system based on water-water heat pump with radiant panels and a ventilation energy recovery system for residential air-conditioning and tap water production

Abstract

This plant (installed in a 200 m2 two-floor house in Pordenone - Italy) is made up of a well-water condensed heat pump with variable flow 'digital' scroll compressor and of ceiling radiant panels. The heat pump also supplies the tap water storage tank. A mechanical ventilation plant controls the indoor air quality and allows active energy recovery from the exhaust. The system mounts new high efficiency electronic filters. The CPU of the system programs and controls the entire system. A simplified physical model of the plant was built to calculate its annual efficiency, the energy consumption of each component and its life cycle costs.
