Low GWP Refrigerants
- System Solutions and Components
Climate change is going on around us, across the world. There is no doubt that we, mankind, is the reason behind this development – and there is also no doubt that we need to tackle it. The deployment of heat pumping technologies is one way to do this, leading to energy efficiency and reduction of CO2 emissions. Unfortunately, the refrigerants currently used in heat pumps have a high global warming potential (GWP) and are thus themselves potent climate gases. But it doesn’t have to be like that. There are also refrigerants with significantly lower GWP, both such that have been known for a long time and more recently developed ones. Some of these come with another challenge: they are flammable to different degree, which needs to be dealt with.
This issue of HPT Magazine focuses on low GWP refrigerants, their system solutions and the systems’ components. The importance of the shift is underlined in the Foreword, and is further discussed in the Column, also giving some background regarding the situation in the EU. The News in focus gives an overview of an unwanted consequence of the EU F-gas regulation: illegal refrigerant sales.
The three topical articles shed light on different aspects of low GWP refrigerants: the situation in forerunner Japan, development of centrifugal chillers, and also challenges due to the flammability. The non-topical article describes new combinations of heat pumps and district heating systems.
