Air conditioning system and method of control

An air conditioning system and control method to allow individual zone thermostats to directly control a variable capacity compressor and adaptively adjust the indoor supply air volume to meet zoning demands, without using static pressure or flow sensors or entering a set of pre-defined air flow values for each zone into a controller. The method controls an air conditioning system that is able to receive signals or commands from individual zone thermostats and give priority to a highest demand zone / thermostat. For example, a priority thermostat can be used to directly control the variable capacity compressor via an indoor controller and outdoor controller.

Air conditioner and method of controlling the same

An air conditioner has a variable capacity rotary compressor, which allows the compressor to be smoothly re-started, thus increasing start reliability of the compressor. The air conditioner includes a compressor rotated in opposite directions. A drive unit rotates the compressor in a forward or reverse direction. A start determining unit determines whether the compressor has started to rotate in a forward direction or not. A control unit operates the drive unit so as to rotate the compressor in a direction opposite to the forward direction, and then re- start the compressor in the forward direction, when the compressor has failed to start. The air conditioner and a method of controlling the air conditioner allow the compressor to be smoothly and rapidly re-started even when the compressor has failed to re-start, thus increasing start reliability, and shortening a time required to re-start the compressor.

Control scheme for coordinating variable capacity components of a refrigerant system

A refrigerant system adjusts, in a coordinated prioritized manner, the variable capacities of a compressor, evaporator fan and a condenser fan to minimize the system's overall power consumption while maintaining a comfort zone within a target comfort range. The target comfort range is defined by desired temperature and humidity limits. When the comfort zone is within the target comfort range, the system periodically attempts to reduce the compressor capacity. If the attempt succeeds, the evaporator fan capacity is then minimized. The condenser fan capacity can also be minimized provided the refrigerant system can maintain at least a minimum saturated suction temperature of the refrigerant flowing from the condenser to the compressor.
