A team of researchers from the U. S. Department of Energy Ames National Laboratory developed a magnetocaloric heat pump that matches current vapor-compression heat pumps for weight, cost, and ...

An international research team has investigated how thermoelectric subcooling may be integrated into propane heat pumps to reduce power consumption in the vapor compression system. Their work showed ...

Vapor compression cycles are predominantly used in air-conditioning, heat pump and refrigeration equipment. A good understanding of transient behaviors of vapor compression systems is critical to ...

Given the environmental concerns of ozone depletion and global warming, an increasing amount of thought, effort, research, and financing is being given to natural refrigerants. Natural refrigerants, ...
