Friedrich Chill Premier 10000 BTU Smart Window Air Conditioner CCF10A10A. Best for: Large rooms This model can cool a 400- to 500-square-foot space with ease thanks to its 10,000 BTUs and eight ...
Air-conditioner sizes are often given as "tons" of cooling, where 1 ton of cooling equals 12,000 BTU/h (3.5 kW). 1 ton of cooling equals the amount of power that needs to be applied continuously over a 24-hour period to melt 1 ton of ice. The annual cost of electric energy consumed by an air conditioner may be calculated as follows:
The heat pump is significantly more energy-efficient than electric resistance heating, because it moves energy from air or groundwater to the heated space and the heat from purchased electrical energy. When the heat pump is in heating mode, the indoor evaporator coil switches roles and becomes the condenser coil, producing heat.
A realistic indication of energy efficiency over an entire year can be achieved by using seasonal COP or seasonal coefficient of performance (SCOP) for heat. Seasonal energy efficiency ratio (SEER) is mostly used for air conditioning. SCOP is a new methodology which gives a better indication of expected real-life performance of heat pump ...
The energy-efficient home improvement credit offers tax credits of up to $2,000 for heat pumps or biomass stoves or boilers, and up to $1,200 for other energy-efficient property upgrades.
Better air conditioning effects; Energy savings of up to 15–20%; Even conditioning [citation needed] A drawback is the installation cost, which can be slightly higher than traditional HVAC systems. Energy efficiency can be improved even more in central heating systems by introducing zoned heating.
