People not in the refrigeration business often think that refrigeration equipment produces cold air; in fact, the equipment is actually removing heat from air and leaving what’s left — the cold. When ...

A while back, I addressed the energy savings potentials behind a drain waste heat recovery heat exchanger. It has the potential of reducing energy consumption of residential applications by as much as ...

Enthalpy? A Fancy Word for Heat! This program presents the important concepts of pressure enthalpy in a manner that will appeal to the service technician. Each refrigerant has its own properties and ...

Adsorption refrigeration systems and heat pumps are emerging as compelling alternatives to conventional vapour compression technologies, offering enhanced energy efficiency and environmental benefits.

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 ...

A group of scientists led by the Zhejiang University in China has developed a novel zeotropic refrigerant that can reportedly improve the performance of air-source heat pumps (ASHPs), while also ...

A secretive vote in the arcane and Byzantine world of international safety standards late last month may lead to a dramatic reduction in greenhouse gas emissions from home heating and cooling systems ...
