Heat pumps can be classified based on parameters like heat source and system configuration. Among the various types of heat pumps available in the market today, however, the two major types that are mainly used for heating of building interiors and domestic hot water in Australia are Air-source Heat ...
CO2 heat pumps are rapidly becoming available in a wide variety of configurations and from a wide range of suppliers. In this final article, we use the Revere™ CO2 heat pumps available from Automatic Heating to demonstrate the key performance features of CO2 heat pumps. Efficiency The COP of CO2 ...
The history of heat pump, and refrigeration in general, goes back a long way and have been studied since the 1700’s. In 1748, Scottish professor William Cullen designed a small refrigerating machine that utilized a pump to create vacuum over diethyl ether, which caused ether to boil and absorb ...
The refrigerant market has been subject to significant changes over the past 40 years because of concern about the environmental impacts of refrigerants. The Montreal Protocol (1987) initiated the phase out of CFC (chlorofluorocarbon) refrigerants such as R11 and R12 because of the massive damage these were doing to ...
Normally when we think of efficiency, we think of a percentage, i.e. of the energy we put into an appliance, only some of it provides a useful output and some is wasted. Thus we talk about a boiler being 90% efficient – because only 90% of the fuel ...
An Introduction to Heat Pumps A heat pump is a device that is primarily used to transfer heat from a lower ambient temperature into a higher temperature system. Its function is, in essence, pumping heat from one place to another, that is why it is called a ‘heat pump’. This ...
Commercial Heat Pumps for Hot Water and Heating Hot Water Heat Pumps provide a highly efficient means of heating hot water for many commercial and industrial applications. Achieving an average COP of 4.2 means that the energy efficiency of Heat Pumps is over 4 times that of conventional water heaters. Being ...
