Air To Air Heat Pump Efficiency

Air to air heat pump is one of the most efficient electric hvac devices designed for home heating and cooling.

Air to air heat pump 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. 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. 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.

Efficiency and performance deteriorate if airflow is much less than 350 cfm per ton. Rheem heat pumps can deliver quiet efficient heating and cooling. The efficiency of air source heat pumps is measured by the coefficient of performance cop. 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 cop of 3 means the heat pump produces 3 units of heat energy for every 1 unit of electricity it consumes. 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. We will look at cop in terms of air source heat pumps.

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. 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 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. Within temperature ranges of 3 c to 10 c the cop for many machines is fairly stable at 3 3 5.

Heat pumps can have problems with low airflow leaky ducts and incorrect refrigerant charge. 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. 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. 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.
