Chat NowThis is a very useful ratio, since the energy yield E is a measure of the earnings potential while the peak power reflects the cost of the system. Note that the peak power in the above formula is the module's peak power, not the system's installed capacity, which is P sys = P module η sys. Energy Losses

Chat NowThe Energy Efficiency Ratio (EER) of an HVAC cooling device is the ratio of output cooling energy (in BTU) to input electrical energy (in watts) at a given operating point. EER is normally calculated with a 95 °F outside temperature and an inside (return air) temperature of 80 °F and 50% relative humidity.

Chat NowHow to Calculate Savings-to-Investment Ratios. by Lisa S. Kramer . A person or business uses the savings-to-investment (SIR) ratio to determine whether the potential savings of a project justifies the initial investment.

Chat NowA room air conditioner's efficiency is rated according to the Energy Efficiency Ratio (EER). This is the ratio of cooling capacity to the power input, or how well it cools compared to how much energy it needs. The ratio is measured in British thermal units (Btu) per hour. The higher the EER, the more efficient the unit.

Chat Now. A safe ratio has been defined as one with no detectable adverse effects. The hypothesis was that a protein-energy ratio of 1.7 g/100 kcal is adequate and safe. Methods: Healthy male infants were fed Formula 1.7, a milk-based formula, as the sole source of energy from the 8th to the 112th day of life. Weight, length, and energy intake were measured; serum albumin and urea …
