System and Method of Controlling a Variable-Capacity Compressor

摘要

A system includes a variable-capacity compressor operable in a first capacity mode and in a second capacity mode that is higher than the first capacity mode. A variable-speed blower is operable at a first speed and at a second speed that is higher than the first speed. A control module is configured to (i) receive indoor relative humidity data corresponding to an indoor relative humidity (ii) switch the variable-capacity compressor between the first capacity mode and the second capacity mode based on a demand signal from a thermostat and the indoor relative humidity and (iii) switch the variable-speed blower between the first speed and the second speed based on the demand signal from the thermostat and the indoor relative humidity.
