Today, a growing number of suppliers offer low GWP, natural refrigerant (NR) heat pump technologies ready to help satisfy demands for zero-energy buildings, high COP, and higher comfort often demanding mutual heating and cooling. However, while worldwide four million CO2 refrigerant hot water heat pumps have been produced, the technology has been
largely confined to Japan where such systems have reached highest market penetration levels thanks to strong governmental support and a well-established supply industry. This
paper serves as a summary of market, technology and policy developments affecting the uptake of NR heat pumps. It integrates data from two studies conducted by shecco among the European and North American HVAC&R industry, as well as information obtained during leading conferences and trade shows 2011-2014.
