A new design for an air-source heat pump using a ternary mixture for cold climates.

Type of article: Article

Summary

The paper presents a performance analysis of the newly developed combined cycle fully integrated air/air heat pump (CFIA). This system combines the proven efficiencies of heat pump technologies with heat regenerative technologies to bring the most efficient heating/cooling system with capabilities to produce domestic hot water. It uses environmentally sound refrigerant blends. Extensive laboratory testing showed that the system yielded an impressive COP, higher than 2.7 at -15 deg C outside temperature. Furthermore, field testing revealed an average COP of 2.4 at -13.5 deg C outside temperature.
