What does the word seer stand for when inquiring about heat pumps?
Seasonal Energy Efficiency Ratio - the higher the number = more energy efficiency of the unit
What is the energy rating on this Air conditioning Unit?
The Energy efficiency rating for the LG 3850 BTU Air Conditioner/Heater unit is 9.7.
What is imperial unit of energy equal to 750 watts?
0.75 kW
What compares the energy output of a system with its energy input?
Is it's Energy Efficiency.
If the energy supplied to the machine is 4000 watts for 91 percent efficiency what is the amount being used for work?
The idea here is to calculate 91% of 4000. By the way, technically "watts" is not a unit of energy. It is a unit of power - that is, energy per unit time.
What is the coal energy efficiency?
If it is burned - which is the way such fuels are usually used - the energy efficiency is the energy efficiency of a heat engine. The theoretical maximum efficiency is the Carnot efficiency; the real efficiency will usually be considerably less than that.
How much energy does a central air conditioner use?
Energy consumption depends on the capacity and efficiency rating or SEER of the unit. For instance a five ton unit uses more energy than a 3 ton unit with the same SEER rating and a 16 SEER unit uses less energy than a 10 SEER unit of the same capacity. See www.energystar.com for more info
SI unit for efficiency?
Efficiency is normally written as a percentage, and does not have an SI unit."percent". It has no units.
What does BRECSU stand for?
BRECSU = Building Rsearch Energy Conservation and Support Unit, set up as part of the Building Research Establishment's programme of assisting and developing energy efficiency and energy saving in buildings.
The percentage of energy from a fuel that is actually used to perform work is its?
That is called efficiency. An efficiency of 1 (or 100%) means that all the energy is converted into useful work.That is called efficiency.

What is the unit used for structural efficiency?
There is not supposed to be a unit. Its just a number. Example: the structure can hold 6kg. the structure is 2kg. The Structural efficiency is 3 (no unit)
What is mean of pump efficiency?
The ratio between the energy efficiency of pumps and pump uses the energy that does. Pump efficiency is determined by the manufacturer. In the calculation of pump efficiency is 70%.
