1. Compressor -The compressor is often referred to as the heart of a heat pump. This device pumps and compresses the refrigerant that provides the heating and cooling benefits of a heat pump. All Amana® brand high-efficiency units feature scroll compressors offering lower sound ratings compared to reciprocating compressors. Scroll compressors also contain up to 70% fewer moving parts. Amana brand energy-efficient models use a mix of scroll and reciprocating compressors optimized for the application.

3. Crankcase Heater — The factory-installed crankcase heater is wrapped around the base of the compressor and provides multiple functions. When the heat pump is shut down in colder ambient conditions, the crankcase heater reduces liquid refrigerant migration in the compressor shell by keeping the refrigerant at a temperature higher than the coldest part of the refrigerant system. System oil will generally migrate to the warmest part of the refrigerant system. By keeping the compressor warm the crankcase heater helps to keep oil in the compressor where it is needed. Not only does this protect the compressor but noise reduction is achieved by preventing liquid refrigerant accumulation in the compressor shell.

6. Low-Pressure Switch — When the refrigerant charge or pressure in a heat pump system is low, this switch activates and stops the operation of the heat pump to minimize potential damage to the compressor. A heat pump system that is low on refrigerant will not provide adequate heating or cooling. Further, low or loss of pressure can cause freezing of the condenser coil which drastically hinders the performance of a heat pump. This silent guard stands ready to operate only when needed to help protect the heat pump’s compressor from damage.

7. Compressor Sound Blanket — The sound blanket insulates against the normal operating sound of the compressor. But not all sound blankets are created equal. Unless it’s constructed of high-density, thick foam and other materials, it may not provide the same level of sound insulation.

THE MAKING OF A MILLION-AIR^® Heat Exchanger

WRINKLE-BEND TECHNOLOGY

How the tubes in a tubular heat exchanger are bent is critical. Some designs simply bend the tubing, thus stretching the metal on the outside of the tube while compressing the metal on the inside. Our unique process carefully forms the tubing to create precisely placed wrinkles to reduce the likelihood of weak points in the metal. And the wrinkles have an added benefit: they cause turbulence inside the tube, forcing more heat to the tube walls for even greater efficiency.

DUAL-DIAMETER TUBING With dual-diameter tubing, heat transfer is maximized. As hot gases pass from the larger to the smaller diameter tube, the velocity of the gas increases. This helps to ensure the best possible heat transfer to the home.

MUFFLER JOINT TECHNOLOGY Where the tubes are joined together and to the vestibule panel, the Million-Air Heat Exchanger takes advantage of the properties of thermal expansion. The larger tube is drawn to a smaller diameter and fitted inside the smaller tube. During operation, the larger tube is hotter, and the joint actually becomes more solid. The same principle is employed where the tubes are joined to the vestibule panel.
