The efficiency of air source heat pumps is measured by the coefficient of performance cop.
Air to air heat pump efficiency.
Within temperature ranges of 3 c to 10 c the cop for many machines is fairly stable at 3 3 5.
Using this scale commercial air source heat pump efficiency can be as high as 4 whereas ground source heat pumps can reach up to 5.
Heat pumps can have problems with low airflow leaky ducts and incorrect refrigerant charge.
Air to air heat pump is one of the most efficient electric hvac devices designed for home heating and cooling.
One of the biggest advantages of an air source heat pump is its efficiency.
Models that are built as the energy star are able to save up to 20 percent than standard models reduce the greenhouse gases emission and increase the comfort.
Especially popular in moderate climates a heat pump is considered to be an energy efficient alternative to a traditional heating and cooling system i e a gas furnace with a central air conditioner.
Air to air heat pumps are highly efficient with their seasonal efficiency rating scop reaching 3 0 4 0 meaning that for every 1 kw of electricity 3 to 4 kw of heat is generated.
Rheem heat pumps can deliver quiet efficient heating and cooling.
This means that for every unit of electricity you put in the heat pumps have the potential to produce 4 and 5 units of heat respectively.
A heat pump gets its name because it pumps or transfers heat from one area to another instead of generating heat like forced air furnaces or radiant heat boilers.
A well installed air source heat pump system is capable of providing 1 5 to 3 times the amount of electrical energy it consumes in the form of heat energy for your home.
We will look at cop in terms of air source heat pumps.
Efficiency of a heat pump is measured using a term coefficient of performance cop and it is the ratio of the useful heat that is pumped to a higher temperature to a unit amount of work that is put in.
Efficiency and performance deteriorate if airflow is much less than 350 cfm per ton.
There should be about 400 to 500 cubic feet per minute cfm airflow for each ton of the heat pump s air conditioning capacity.
A cop of 3 means the heat pump produces 3 units of heat energy for every 1 unit of electricity it consumes.
Efficiency of a heat pump.
It is thermodynamically impossible to have an efficiency of more than 100 as this implies that more energy is being produced than is being put in.
This is possible because air source heat pumps move heat rather than burning fuel.
