Sample questions
01What is the efficiency rating of a typical modern LED lamp?
- A10-15 lumens per watt
- B200-300 lumens per watt
- C80-150+ lumens per watt
- D40-50 lumens per watt
Why: Modern LED lamps typically achieve 80-150+ lumens per watt, compared to around 10-15 for incandescent lamps.
02What does 'COP' stand for in heat pump terminology?
- AContinuous Output Power - the maximum heat output the unit can sustain
- BCoefficient of Performance - ratio of heat output to electrical input
- CCompressor Operating Pressure - the working pressure of the refrigerant circuit
- DCost of Power - the running cost of the heat pump per kilowatt-hour
Why: COP (Coefficient of Performance) is the ratio of heat output to electrical energy input. A COP of 3 means 3kW heat output for 1kW electrical input.
03What typical COP can an air source heat pump achieve?
- A0.5-1.0
- B2.5-4.0
- C100+
- D10-15
Why: Air source heat pumps typically achieve COP values of 2.5-4.0, meaning they produce 2.5-4 times more heat energy than the electrical energy consumed.
