Psi measures the amount of pressure placed on a square inch of space. If you’re planning on using attachments or compressor tools, such as grinders and nailers, you’ll want to pay attention to airflow because the air compressor has to match or exceed the CFM or SCFM rating of the tools. Generally speaking, SCFM measures airflow in perfect conditions, while CFM measures airflow in realistic conditions.

SCFM is measured in a controlled environment at 68 degrees Fahrenheit, 14.7 pounds per square inch (psi), and 36% humidity, while CFM is only measured at 90 psi. AirflowĬubic feet per minute (CFM) and standard cubic feet per minute (SCFM) are used to measure airflow. The higher the horsepower, the faster the motor can refill the compressor’s tank. The speed at which the motor works is measured in horsepower. While you don’t have to worry about maintenance with an oil-free compressor, the Teflon coating eventually wears off, requiring you to buy a new compressor. Oil-free compressors have Teflon-coated cylinders that don’t require lubrication. Oil compressors require the occasional refill so that the cylinders stay lubricated. MaintenanceĬompressors are either oil-lubricated or oil-free. Both types are useful in supplying air to a variety of power tools and other pneumatic tools.

Electric air compressors are portable if they’re meant for household tasks or immobile if they stay in a workshop. Gas air compressors are large, stationary units that are meant for commercial use. Fuel SourceĪir compressors are powered by electricity or gas. To that end, DOE launched the Residential Cold Climate Heat Pump Technology Challenge in 2001 to accelerate deployment of cold climate heat pump technologies.Read our guide below to learn about some of the most important factors to consider before choosing an air compressor. Department of Energy (DOE) is still researching ways to make heat pumps more affordable and efficient. Actual energy savings depend on the relative costs of the combustion fuel relative to electricity.Įven with the impressive performance of heat pumps, the U.S.

In comparison with a combustion fuel-fired furnace or standard heat pump alone, this type of system can also be more economical. According to some reports, heat pumps with scroll compressors provide 10° to 15☏ (5.6° to 8.3☌) warmer air when in the heating mode, compared to existing heat pumps with piston compressors.Īlthough most heat pumps use electric resistance heaters as a backup for cold weather, heat pumps can also be equipped in combination with a gas furnace, sometimes referred to as a dual-fuel or hybrid system, to supplement the heat pump. This helps solve the problem of the heat pump operating less efficiently at low temperatures and reduces its use of electricity. There are few heat pump manufacturers that incorporate both types of heat in one box, so these configurations are often two smaller, side-by-side, standard systems sharing the same ductwork. Compared to the typical piston compressors, scroll compressors have a longer operating life and are quieter. One remains stationary, while the other orbits around it, compressing the refrigerant by forcing it into increasingly smaller areas. A desuperheater-equipped heat pump can heat water 2 to 3 times more efficiently than an ordinary electric water heater.Īnother advance in heat pump technology is the scroll compressor, which consists of two spiral-shaped scrolls. Some high-efficiency heat pumps are equipped with a desuperheater, which recovers waste heat from the heat pump's cooling mode and uses it to heat water.

It also minimizes the noise from the blower running at full speed. The variable-speed controls for these fans attempt to keep the air moving at a comfortable velocity, minimizing cool drafts and maximizing electrical savings. Some models of heat pumps are equipped with variable-speed or dual-speed motors on their indoor fans (blowers), outdoor fans, or both. Zone control systems, often found in larger homes, use automatic dampers to allow the heat pump to keep different rooms at different temperatures. Two-speed heat pumps also work well with zone control systems. Unlike standard compressors that can only operate at full capacity, two-speed compressors allow heat pumps to operate close to the heating or cooling capacity needed at any particular outdoor temperature, saving energy by reducing on/off operation and compressor wear. A number of innovations are improving the performance of heat pumps.
