Vertical ground loop
Slinky
What gas is released from fossil fuels when burned?
Oxygen
Carbon dioxide
Hydrogen
Nitrogen
Which type of solar collector is more efficient but more expensive?
Flat plate collector
Evacuated tube
Oval plate collector
Extended tube
What is meant by the term ‘heat-led’ when referring to a micro combined heat and power system?
More heat is used for heat than to produce electricity
More heat is used to produce electricity than to provide heat
More heat is wasted when producing electricity
The heat must be at a higher temperature when producing electricity
Which item does an air source heat pump contain?
Temperature differential controller
Collector plate
Condenser
Heat sink
What does a differential temperature controller do?
It energises the collector
It activates the pump when there is enough heat
It transfers the heat in the cylinder
It governs the heat intake from the sun
Which one of these is a benefit from an air source heat pump?
High efficiency
Quiet to run
Low installation costs
No chance of freezing
When using a heat pump, which factor is important?
Daylight hours
Eco-efficiency of temperature
Coefficient of performance
Efficiency of material
What type of environmental technology system is shown in the diagram below?
Air source heat pump
Solar heat pump
Ground source heat pump
Two-part heat pump
What is the process called when plants grow and absorb carbon?
Photocronic
Photogenic
Photosynthesis
Photochromesis
What gas has been absorbed by biomass material whilst it grows?
Carbon dioxide
Nitrogen
Carbon monoxide
Hydrogen
What type of ground loop system is shown in the diagram below?
Vertical loops
Horizontal loops
Slinkies
Closed loops
Why does biomass not add to global warming when burned?
It absorbs carbon dioxide when burned, thus reducing its carbon footprint
It absorbs as much CO2 when growing as it releases when burned
Biomass has no carbon in it, so it is carbon neutral
Being natural, it has no effect on carbon emissions
Which of the following materials is not a biomass material?
Wood
Straw
Coal
Animal waste
What is a typical heat-to-electric ratio on a micro combined heat and power system?
60% heat and 40% electric
72% heat and 28% electric
85% heat and 15% electric
90% heat and 10% electric
Which of the following component parts is not installed in a micro combined heat and power system?
Engine burner
Heat exchanger
Evaporator
Stirling engine
What system is shown in the diagram below?
Rainwater harvesting
Greywater re-use
Greywater harvesting
Rainwater re-use
Which is the best orientation for solar thermal systems?
North
South
East
West
