Heat pumps operate by moving heat from lower temperature areas to higher temperature areas. They typically take advantage of an electrically driven compressor and a closed vapor compression cycle.

In order to service and troubleshoot an air-source heat pump system, a service technician must understand the unit's sequence of operation. This is the order of events the system undergoes to cycle ...

Heat pumps are becoming all the rage around a world that has to slash carbon emissions rapidly while cutting energy costs. In buildings, they replace space heating and water heating — and provide ...

Gas engine-driven heat pump systems integrate a combustion engine with conventional vapor compression technology to provide heating and cooling while utilising waste heat recovery. These systems offer ...

UK-based researchers have developed a novel method to estimate the amount of defrost cycles a heat pump will experience in the winter and how much energy it would require to implement the cycles. The ...

Homeowners looking for an energy-efficient alternative to traditional air conditioners in the spring and summer months (and furnaces in the winter) might want to invest in a heat pump. It's a type of ...

A heat pump heats and cools your home, functioning like a combined furnace and central air conditioner. Because they absorb and move heat from the air, heat pumps are exceptionally energy-efficient ...

A group of researchers in Thailand outlined a new methodology to identify the optimal temperature in two-stage cascade heat pumps using non-azeotropic refrigerants. Through their analysis, the ...
