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 ...

Refrigerant circuit restrictions can be common things like a plugged filter drier or a restricted metering device. They can also be more difficult to diagnose and exotic issues like a kinked liquid ...

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 ...

A recently filed patent (Publication Number: US20230296299A1) describes a refrigeration cycle apparatus that includes a unique filter member designed to capture acid contained in the refrigerant. The ...

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 ...

Propane heat pumps for indoor use in single-family homes are now one step closer to commercialization. Germany’s Fraunhofer ISE has successfully developed a model of a heat pump refrigeration circuit ...

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 ...

One of the great inventions of our time — in terms of its social impact and influence on the health care and food preservation industries — refrigeration equipment is everywhere, from hotels, ...
