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 ...

The EFC2400 leverages nearly a decade of our experience in customer‑specific natural refrigerant systems and packages ...

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 ...

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 ...

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 ...

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 ...

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 ...

Article 440 applies to electrically driven air-conditioning and refrigeration equipment. The rules in this Article add to, or amend, the rules in Art. 430 and other Articles in the NEC [440.3(A)]. A ...
