Musings on HVAC&R-Heat Pumps and Heat Storage

Heat pumps are rapidly expanding as an effective means of preventing global warming and promoting carbon neutrality as heating equipment that can replace fossil fuel combustion equipment. The efficiency of heat pumps has been improved, but the rise in efficiency has slowed down. As a measure to further improve the efficiency of heat pumps, uses of efficient heat transfer and heat storage, in addition to improving the efficiency of the equipment itself, can provide efficient cooling, heating, along with hot water supply when needed and with the desired quantity of hot water.
