Abstract:
A climate-control system may include a variable-capacity compressor unit and a control module controlling the compressor unit. The compressor unit may be operable in a first capacity mode and in a second capacity mode that is higher than the first capacity mode. The control module may be configured to switch the compressor unit among a shutdown state, the first capacity mode and the second capacity mode based on a demand signal and outdoor-air-temperature data.
Abstract:
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.
