CONTROL SYSTEM AND METHOD FOR BOTH ENERGY SAVING AND COMFORT CONTROL IN AN AIR CONDITIONING SYSTEM
First Claim
8. A control method for controlling both temperature and humidity in an air conditioning system having a variable-speed compressor and a variable-speed indoor blower, comprising:
- determining a target speed of said compressor based on sensed and setpoint temperatures;
determining a target speed of said indoor blower based on sensed and setpoint humidities;
employing said target speed of said compressor to control said compressor of said air conditioning system; and
employing said target speed of said indoor blower to control said indoor blower of said air conditioning system.

Abstract
A control system and method for controlling both temperature and humidity in an air conditioning system having a variable-speed compressor and a variable-speed indoor blower. In one embodiment, the control system includes: (1) a temperature control loop in which a target speed of the compressor is determined based on sensed and setpoint temperatures and (2) a humidity control loop, located in the temperature control loop, in which a target speed of the indoor blower is determined based on sensed and setpoint humidities, the target speed of the compressor employable to control the compressor and the target speed of the indoor blower employable to control the indoor blower of the air conditioning system.
