aThe annual energy consumption and utility cost of the solar assisted heat pump systems were compared to a market available air source heat pump, a ground source heat pump system as well as the typical reference housing heating and cooling system. 太阳协助的热泵系统的每年能源消耗和通用费用与市场...
athe cost of tuition continues to climb each year,which has constituted a heavy burden upon students from poverty-stricken areas 学费的费用继续每年上升,构成了重的负担在学生从贫乏的区域[translate] a 这是一个在使用后可折叠为墙面壁板的淋浴房。壁板内整洁地藏匿有龙头、花洒、沐浴露、洗发液等。这种新...
Finally, by exploiting present worth method, rate of return is discussed with respect to present energy cost. Sensitivity analysis shows that only with actual prices of energy and low interest rate, the investment is justified. 展开 关键词: Case study for Tehran Environmental features Rate of ...
The annual thermal performances of the proposed system were estimated and they were economically assessed using the economic model. The appropriate replacement configurations for the system can be determined for lower solar electricity cost. Therefore, this system may utilize solar energy on the utility...
The maximum number of equal-cost routes for load balancing can be configured using the maximum load-balancing command. To cancel load balancing, you can set the maximum number of equal-cost routes to 1. This example applies to the following products: S3700-EI, S3700-HI S5700-EI, S5700-HI...

Effective hole extraction using MoOx-Al contact in perovskite CH3NH3PbI3 solar cells We report an 11.4%-efficient perovskite CH3NH3PbI3solar cell using low-cost molybdenum oxide/aluminum (i.e., MoOx/Al) as an alternative top contact to repl... Y Zhao,AM Nardes,K Zhu - 《Applied Physics ...
sufficient safety margin, a closed loop crossover frequency (fCC) should be sufficiently below the RHPZ frequency to account for variability of the internal components of the IC as well as variability of external in- fluences on the converter response at the cost of possibly higher loop ...
The best way to compare the cost of running different appliances is to look at theirpower consumption, which is measure of how much power they use inWatts. The following list points out typical values for the wattage of some devices you would find in your home so that you can compare them...
