I recently read an Internet posting asserting that heat pumps, both air-source and geother-mal, should not be considered renewable-energy heat sources. The author pointed to the fact that such heat pumps are driven by electricity, which may come from a power plant that burns coal or natural...
Through installing efficient and low-carbon technologies such as solar panels, heat pumps, energy storage, making use of smart and digital tools. 通过安装高效低碳技术,如太阳能电板、热泵、储能装置等同时利用智慧数位工具。 All technologies we already have. 这些技术我们都有。 And in many cases their ...
aFor areas not located in temperate climates, ground-source (or geothermal) heat pumps provide an efficient alternative. The difference between the two heat pumps is that the ground-source has one of its heat exchangers placed underground—usually in a horizontal or vertical arrangement. 为位于温带...
Trying to determine what appliances qualify for an energy tax credit? The IRS offers several credits that reward taxpayers for investing in certain energy-efficient improvements, like heaters, windows, and more. If you recently invested in energy-effici
[translate] aOther types of heat pumps are water-source and air-earth. If the building is located near a body of water, the pond or lake could be used as a heat source or sink. 正在翻译,请等待...[translate]
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]
Gas-powered vehicles waste about 80% of the energy in their fuel. Most of the energy is consumed by the heat produced in the engine. Other energy inefficiencies stem from pumps and fans cooling the engine, mechanical friction within the transmission and drivetrain, and auxiliary electrical compone...
energy-efficient, well-insulated building envelope with fewer windows and electrification of heat pumps and plumbing, as well as limited use of rooftop solar. The V-shaped structure has also been sited in a way that provides additional harbor views and maximizes natural lighting to reduce ene...
A.Heat pumps are not efficient in supplying heat in coldness. B.Heat pumps can find applications everywhere. C.Heat pumps are of no use at all. D.The inner structure of a heat pump is so complex that it has already been out of date. ...
由于该技术大力降低了电磁干扰 (EMI),与上一代产品相比,SPM31 IPM 的功率损耗降低了多达 10%,功率密度提高了多达 9%,IGBT 芯片尺寸缩小了 20%。功率密度的提高有助于设计人员简化布局,腾出热泵系统中的宝贵空间,同时提高效率。SPM31 IPM 提供多种额定电流选项,范围从 15 至 35 安培 (A) 不等。
