Abstract
Embodiments of a modular air conditioning (AC) unit include a base unit, a blower mounted to the base unit, and at least one heat exchanger module assembled to the base unit and communicatively coupled to the blower to form a modular AC circuit. The modular AC unit also includes a controller communicatively coupled to at least one component of the modular AC circuit and adapted to independently control operation of each of the components of the modular AC circuit.
Claims20
A modular air conditioning (AC) unit, comprising:
- a base unit;
- a blower mounted to the base unit and configured to provide air to a grounded aircraft;
- at least one heat exchanger module assembled to the base unit and communicatively coupled to the blower to form a modular AC circuit;
- and
- a controller communicatively coupled to at least one component of the modular AC circuit and configured to control operation of the modular AC circuit in at least one of a heat mode, a cool mode, and a vent mode based upon at least two of aircraft size, HVACR mode, and the capacity of the modular AC unit.
A modular air conditioning (AC) unit comprising:
- a modular AC circuit comprising a blower module and at least one heat exchanger module;
- a controller coupled to the modular AC circuit and configured to control operation of the modular AC circuit based on cabin temperature feedback when a cabin temperature probe is functioning and to control operation of the modular AC circuit based upon at least one of ambient temperature feedback and discharge air temperature feedback when the cabin temperature probe is malfunctioning.
A modular air conditioning (AC) unit, comprising:
- a base unit;
- a blower mounted to the base unit;
- a plurality of modular heating, cooling, or ventilating circuits assembled to the base unit and communicatively coupled to the blower;
- and
- a common controller communicatively coupled to the plurality of modular heating, cooling, or ventilating circuits and configured to independently control operation of each of the heating, cooling, or ventilating circuits.
