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 ...

The outlet temperature of the heat recovery reservoir is an important parameter in the design of refrigeration with heat recovery systems. In this paper the second law of thermodynamics has been ...

It is widely believed that heat pumps are a key technology for heat decarbonisation to reach the net zero greenhouse gas emission target by 2050, but their uptake has not been as fast as expected so ...

A group of researchers led by the Chinese Academy of Sciences (CAS) has developed a heat-driven thermoacoustic refrigerator/heat pump (HDTAR/HDTAHP) for high heating-temperature operation. They ...

At first glance, heat and cold do not have much to do with quantum physics. A single atom is neither hot nor cold. Temperature can traditionally only be defined for objects that consist of many ...

Heat pumps function similarly to refrigerators or air conditioners, which take warm air from one space and send it to another. In the winter, a heat pump transfers heat from the outdoors inside and, ...

Most heat pumps fall into the broad categories of ducted or ductless, but there are also a number of subcategories you should be aware of when choosing a heat pump for your home. Sam Becker ...

South Africa scientists have developed an integrated, solar-powered heat pump and refrigerator for use by food vendors in sub-Saharan Africa. The dual system is powered by two 90 W solar modules and ...
