Abstract:
Heat pumps for climates where demand for cooling and heating are unequal and methods of adapting and distributing heat pumps for such climates. Heat pumps include a compressor, compressor motor, variable speed drive, and controller. In a number of embodiments, non-volatile memory stores sets of constant speeds for cooling and heating, and a person can select, via an input device, different sets of speeds for cooling and heating to provide the different cooling and heating capacities. The controller then operates the unit at the selected speeds, selecting from within the set based on demand for cooling or heating. In some embodiments, different sets of speeds may have the same minimum speed but different maximum speeds. Identical heat pumps can be configured to have different capacity ratings and different advertised efficiencies for different climates.
