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.
Air to air heat pump efficiency.
The efficiency of air source heat pumps is measured by the coefficient of performance cop.
Heat pumps can have problems with low airflow leaky ducts and incorrect refrigerant charge.
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.
A cop of 3 means the heat pump produces 3 units of heat energy for every 1 unit of electricity it consumes.
An air source heat pump ashp will typically produce around 3kw thermal energy for every 1kw of electrical energy consumed giving an effective efficiency of 300.
Efficiency of a heat pump.
The pump s background noise is insignificant and thus does not represent an annoyance factor for people who will find themselves in the same room with the 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.
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.
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.
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.
This is possible because air source heat pumps move heat rather than burning fuel.
There should be about 400 to 500 cubic feet per minute cfm airflow for each ton of the heat pump s air conditioning capacity.
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.
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.
Rheem heat pumps can deliver quiet efficient heating and cooling.
Within temperature ranges of 3 c to 10 c the cop for many machines is fairly stable at 3 3 5.
We will look at cop in terms of air source heat pumps.
