The energy performance of four kinds of heat pumps in low-temperature WHR is compared and analyzed by the coefficient of performance (COP), exergy efficiency and annual savings of standard coal. The results show that when the heat ratio is higher than about 0.5, the MHP has the best energy...
建议的方式将做补全帐目名和付款目的在付款文件由您的银行。 [translate] aA brief section on the cost of operating different types of heat pumps and conventional electric heating systems is also included. 关于操作热泵和常规电暖系统的不同的类型的费用的一个简要的部分也包括。 [translate] ...
The four key performance aspects of air-source heat pumps in a cold climate are high efficiency, low peak power demand, dependable defrosting, and long-term reliability. Some of these are interrelated, but a space-heating heat pump must excel in each area if it is to be attractive to custo...
ground source heat pump and solar heat pump were compared.Then the merits and drawbacks of the four kinds of air conditioning system were summarized,which could be referenced for choosing heat pump unit in different areas.The result showed that the reasonable application of different heat pump ...
So if the different ground water heat pumps locate in a small area, there will occur thermal disturbance, and the systems maybe in failure in the near future. 合理和这是否是一个严重的问题。 如此,如果不同的地下水热泵位于一个小范围,那里在失败可能将发生热量干扰和系统在不久将来。 [translate] ...
Energy consumption of cold climate heat pumps in different climates - Comparison of single-stage and two-stage systems The constructed unit will undergo a field demonstration in a military barrack to identify heat pumps as cost effective systems that have less primary energy consumption when compared...
Toutrepresent the tank inlet and outlet temperatures while TPCMrepresents the temperature of PCM. This methodology was adopted by Tay et al. [49] to determine effectiveness of tube-in-tank phase changeTES systems. These equations for effectiveness can be used for all kinds of PCM systems includin...
Anyone who experiences a TIA should see their doctor immediately to learn about special steps (including possible medications and surgery) that can decrease the risk of a future stroke. Use of certain kinds of street drugs, like cocaine, amphetamines and heroin, also increases the risk of stroke...
