The model applied in this study includes the simulation of heat pumps and electric vehicles and extents the market diffusion model for PV + battery systems used in Ref. [7]. The first step of the model is to determine the optimal operation of the heat pump (section 3.1). Since heat ...
The use of heat pumps has’ been held back largely by skepticism about advertisers’ claims that heat pumps can provide as many as units of thermal energy for each unit of electrical energy used, thus apparently contradicting the principle of energy conservation. Heat pumps circulate a fluid refr...
Waterfurnace Renewable Energy (TSX:WFI, OTC:WFIFF) launched its new highly efficient 7 Series geothermal heat pumps (GHP) today. The 7 Series commercial release beats Climatemaster's (a division of LSB Industries (NYSE:LXU)) Trilogy 40 as the first commercially available GHP with a variable ...
Heat pumps. Citations from the NTIS data base Technical and economic feasibility of extracting heat from one temperature source and delivering the thermal energy extracted for use at a higher temperature is discussed in abstracts of Federally-sponsored research. Air to air, air to w... AS Hunde...
Concerns about climate-warming refrigerants leaking from heat pumps are valid. Even so, the benefits of installing heat pumps instead of natural gas furnaces far outweigh the drawbacks.
