The energy-efficiency ratings of residential air-source heat pumps have risen dramatically over the last few years, with many manufacturers now offering equipment well exceeding the 20-SEER mark. There have been significant gains made in commercial heat pump efficiencies as well, thanks to the ...
高效管理民用住宅热泵 由于碳减排目标和更多的可再生能源的可用性,热泵市场现在正在快速增长。各国政府也在促进和退税方面投入大量资金。 标准的c.pCO系列解决方案可用于小型/中型OEM(即用型解决方案或轻微客制化),也可用于大型OEM的定制开发。 系统效率的实际提高(直流变频 + EEV) 通过实验室完成的大量试验已经证实...
The Energy Star program also provides a performance rating factor for heat pumps since those units, unlike straight air conditioning systems, operate through both heating and cooling seasons: Heating Seasonal Performance Factor (HSPF): This is a measure of a heat pump's energy efficiency over one...

For example, some heat pumps include a supplementaryelectric resistance heaterto boost output at times of peak demand. Some packaged heat pump equipment incorporates the ground loop and possibly heatingcirculation pumps; in other systems these pumps are installed elsewhere. The complexities of agreeing ...
In this paper, the comprehensive life cycle climate performance (LCCP) assessments are detailed from various influencing parameters for the packaged air source heat pumps. Theseasonal energy efficiency ratio(SEER) rating for heat pump systems has a far greater impact on lowering carbon dioxide equivale...
aAir-source heat pumps at the lower end of the efficiency range are characterized as having single-speed reciprocating compressors. 空气来源热泵在效率范围的末端被描绘作为有唯一速度交换压缩机。[translate]
Although this air mover will cost twice as much as the conventional heat pump air mover, this premium cost should be recoverable in less than four years through energy savings. The sound rating (SRN) for this air mover is less than 20. Means for improving fan efficiency by 5 percentage ...
B Thermal physics, COP upper bound for heat driven heat pumps I made a presentation where I derived, or at least attempted to derive, the formulae for the upper bounds of the efficiency/cop (cop = coefficient of performance) for a heat engine, work driven heat pump, and a heat driven...
