What are the two main types of heat pump?
Air source heat pump and Ground source heat pump
Water source heat pump and Solar heat pump
Electric heat pump and Gas heat pump
Oil heat pump and Biomass heat pump
What are the working principles of a heat pump?
A water pump moves water from a lower level to a higher level through the application of energy.
Refrigerant liquid is warmed by outside air and evaporates to a gas, then the gaseous refrigerant is compressed and its temperature increases which then passes through your cylinder and warms the vessel. The gas then cools and begins to condense to a liquid due to sudden drop in refrigerant pressure.
Heat is generated by burning fossil fuels and then transferred to the property.
Solar panels collect heat from the sun and transfer it to the property.
What is a refrigerant?
A substance or mixture, usually a fluid, used in a heat pump and refrigerant cycle. In most cycles it undergoes phase transition from a liquid to a gas and back again.
A solid material that absorbs heat and releases it slowly.
A type of insulation used in heat pumps.
A device that measures temperature changes.
What are the two temperature scales used within plumbing systems?
Kelvin and Celsius
Fahrenheit and Rankine
Kelvin and Fahrenheit
Celsius and Rankine
What is the general rule with regards to heat transfer?
Heat moves from the warmer spaces to the cooler spaces
Heat moves from the cooler spaces to the warmer spaces
Heat remains constant in all spaces
Heat moves randomly between spaces
What is the role of a compressor in a heat pump?
It compresses the refrigerant causing the gas to heat up
It cools down the refrigerant causing the gas to cool down
It circulates the refrigerant without changing its temperature
It filters the refrigerant to remove impurities
What is the energy efficiency of an A rated condensing gas boiler?
95% (for every 1kw gas input you will receive 0.95kw heat input)
85% (for every 1kw gas input you will receive 0.85kw heat input)
75% (for every 1kw gas input you will receive 0.75kw heat input)
65% (for every 1kw gas input you will receive 0.65kw heat input)
What is absolute zero in both Kelvin and Celsius temperature scales?
0 K and -273 degrees Celsius
0 K and -100 degrees Celsius
0 K and -50 degrees Celsius
0 K and -200 degrees Celsius
How is the efficiency of an ASHP measured?
Coefficient of performance (CoP)
Energy efficiency ratio (EER)
Seasonal energy efficiency ratio (SEER)
Annual fuel utilization efficiency (AFUE)
What is the equation that determines the efficiency of an ASHP?
The heat delivered out of the unit divided by the compressor power or heat delivered into it
The heat delivered out of the unit multiplied by the compressor power or heat delivered into it
The heat delivered out of the unit added to the compressor power or heat delivered into it
The heat delivered out of the unit subtracted by the compressor power or heat delivered into it
