As the commercial HVAC industry shifts toward decarbonization and increased sustainability, the role of mechanical design engineers is evolving rapidly. For new mechanical engineers entering the field ...

Designing a temporary heating system differs considerably from permanent installations. In early construction stages, you might face a tight roof with walls of sheet plastic, or nearly complete walls ...

An international research group investigated hybrid heat pumps (HHPs) as a technically and economically feasible solution to decarbonizing heat supply in old residential buildings and found that it ...

Aggressive decarbonization targets set by government agencies and some owners are requiring the industry to formulate strategies to reduce the embodied and operational carbon in the built environment.

Radiation heat and convection heat exist on stratified air conditioning zone building surfaces in large space, and they have significant impact on cooling load calculation and thermal comfort analysis ...

Load-based testing for heat pumps is an emerging experimental methodology designed to capture realistic, dynamic equipment performance by allowing the system to operate under its native ...

Heating more buildings with electric heat pumps can provide a larger market for renewable energy. Yet while adopting heat pumps, in a practice known as building electrification, “gets a lot of ...
