Air To Air Heat Pump Efficiency

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.

Air to air heat pump efficiency.

This is possible because air source heat pumps move heat rather than burning fuel. Efficiency and performance deteriorate if airflow is much less than 350 cfm per ton. 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. 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.

There should be about 400 to 500 cubic feet per minute cfm airflow for each ton of the heat pump s air conditioning capacity. One of the biggest advantages of an air source heat pump is its efficiency. 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. 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.

Rheem heat pumps can deliver quiet efficient heating and cooling. 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. 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. Within temperature ranges of 3 c to 10 c the cop for many machines is fairly stable at 3 3 5.

Efficiency of a heat pump. 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. 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.

We will look at cop in terms of air source heat pumps. To keep your rheem heat pump in good working condition you should check the air filters every month keep the outdoor coils clean and inspect the blower filters ducts and indoor coil for obstructions and dirt. 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. Heat pumps can have problems with low airflow leaky ducts and incorrect refrigerant charge.
