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.
