Summary

The optimisation of energy consumption, the search for higher system efficiency and the need to reduce CO2 emissions are driving the heat pump market, especially in residential applications. In EMEA especially, the need to switch to alternative refrigerants is changing the criteria for selecting components and developing projects. Most of the market trends have already identified flammable refrigerants as the way to solve compliance issues, while at the same time raising new issues regarding usability and reliability of potentially explosive devices in residential systems. Unit and component manufacturers are starting to work together in order to develop affordable and reliable solutions, not only improving component technologies and their mounting in the unit, but working closely together right from the start of the project. Here below we describe an example of a fruitful collaboration for the development of an R-290 air-to-water heat pump, where accurate unit design, experience as HVAC component and heat pump manufacturers, have led to the development of a product with the highest performance in terms of efficiency and reliability, meeting all the standards for the use of flammable refrigerants on the European residential heating market.
