Claims18
An air conditioning unit for a recreational vehicle, comprising:
- a controller;
- a sealed system operably coupled to the controller and configured for circulating refrigerant, the sealed system comprising a first heater to provide heat to the recreational vehicle;
- a second heater operably coupled to the controller and attachable to the recreational vehicle to selectively provide auxiliary heat to the recreational vehicle;
- an interior temperature sensor operably coupled to the controller to sense an interior temperature of the recreational vehicle;
- and
- an ambient exterior temperature sensor operably coupled to the controller to sense an ambient exterior temperature outside the recreational vehicle;
- wherein the controller is configured to initiate a heating operation comprising
- analyzing the interior temperature of the recreational vehicle,
- analyzing the ambient exterior temperature outside the recreational vehicle,
- determining an operating mode of the air conditioning unit based on the interior temperature and the ambient exterior temperature, the operation mode being selected from a plurality of modes comprising an active first heater mode responsive to analyzing the interior temperature below a first predetermined temperature and an inactive first heater mode responsive to analyzing the exterior temperature below a second predetermined temperature, the second predetermined temperature being lower than the first predetermined temperature, and
- controlling the first heater and the second heater according to the determined operation mode.
A method of operating a recreational vehicle air conditioning unit comprising a first heater attached to the recreational vehicle, a second heater attached to the recreational vehicle, an interior temperature sensor provided inside the recreational vehicle, and an ambient exterior temperature sensor attached to an exterior of the recreational vehicle, the method comprising:
- analyzing the interior temperature of the recreational vehicle;
- analyzing the ambient exterior temperature outside the recreational vehicle;
- determining an operating mode of the air conditioning unit based on the interior temperature and the ambient exterior temperature, the operation mode being selected from a plurality of modes comprising an active first heater mode responsive to analyzing the interior temperature below a first predetermined temperature and an inactive first heater mode responsive to analyzing the exterior temperature below a second predetermined temperature, the second predetermined temperature being lower than the first predetermined temperature;
- and
- controlling the first heater and the second heater according to the determined operation mode.
