Scientists at Germany’s Fraunhofer Institute ISE and a consortium of heat pump manufacturers have achieved a new efficiency record in their development of a low-refrigerant propane refrigeration ...

Currently heat pump manufacturers are mainly focusing on cost reductions and sustainable refrigerants. In the project “LC150” (Low Charge 150 g), the Fraun-hofer Institute for Solar Energy Systems ISE ...

While it might be fair to say that there is no such thing as a typical supermarket refrigeration system, there are commonalities between all systems that employ multiplex compressor racks. It is ...

Heat pumps can now achieve sufficiently high flow temperatures to operate most heating systems, even in older buildings. They are not yet highly efficient, but new refrigerants are expected to provide ...

Multi-circuit evaporators utilizing a thermostatic expansion valve (TXV) will have a refrigerant distributor connected to the outlet of the TXV to ensure the refrigerant leaving the TXV is fed equally ...

As the world intensifies its efforts to mitigate the ongoing climate crisis, R454C refrigerant in recirculating air conditioning units has emerged as an effective way to help data center operators ...

Heat pumps are a key technology in the heat transition, but many of the devices still use environmentally harmful refrigerants. The Fraunhofer Institute for Solar Energy Systems ISE has now developed ...

Andrew Gigiel of the Food Refrigeration and Process Engineering Research Centre has been looking at ways to make domestic refrigerators more energy-efficient. About one billion refrigerators and ...
