Variable speed, electronically controlled, room air conditioner
First Claim
1. An air handling system for heating and/or cooling a room, the system comprising:
- a fan assembly to transport air from the system into the room, the fan assembly having a substantially continuously adjustable speed within a range of speeds defined by a predetermined upper limit and a predetermined lower limit;
a user interface for transmitting a sleep mode signal upon activation of a sleep mode by a user;
a control unit for controlling the fan assembly and the climate control unit to gradually raise an ambient temperature in the room over a predetermined period of time in response to the sleep mode signal transmitted by the user interface; and
a climate control unit for heating and/or cooling the air to be transported from the air conditioner by the fan assembly.

Abstract
A variable speed air handling system for cooling and/or heating a room including a sleep mode. The system includes a fan assembly to transport air from the system into the room, the fan assembly having a substantially continuously adjustable speed within a range of speeds defined by a predetermined upper limit and a predetermined lower limit. A user interface transmits a sleep mode signal upon activation of the sleep mode by a user. A control unit controls the fan assembly and the climate control unit to gradually raise an ambient temperature in the room over a predetermined period of time in response to the sleep mode signal transmitted by the user interface.

6. A variable speed air handling system for heating and/or cooling a room, the air handling system comprising:
-
a fan assembly comprising; fan motor having a single main stator winding; and a fan operatively connected to be driven by the fan motor to transport air from the air handling system into the room; a user interface for inputting at least a desired speed of the fan motor; a control unit for modulating an electrical power signal delivered to the fan motor to substantially continuously adjust the speed of the fan motor according to the desired speed of the fan motor input via the user interface; and a climate control unit for removing thermal energy from the air to be transported from the air handling system by the fan assembly. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A method of controlling an air handling system to be installed in a window of a room, the air handling system comprising a control unit, a climate control unit, and a fan assembly including a fan motor for driving a fan, the method comprising steps of:
-
providing a user interface to allow at least a desired operational mode of the air handling system and a desired speed of the fan motor to be input by an operator; controlling, an operation of the climate control unit in response to the desired operational mode input via the user interface; and adjusting a speed of the fan motor in a substantially continuous manner to drive the fan at the desired speed of the fan motor input via the user interface. - View Dependent Claims (17, 18, 19)

20. A method of controlling an air handling system to be installed in a window of a room, the air handling system comprising a control unit, a climate control unit, and a fan assembly including a fan motor for driving a fan, the method comprising of steps:
-
providing a user interface to allow at least a desired operational mode of the air handling system and a desired speed of the fan motor to be input by an operator; controlling an operation of the climate control unit in response to the desired operational mode input via the user interface; adjusting a speed of the fan motor in a substantially continuous manner to drive the fan at the desired speed of the fan motor input via the user interface; and before the step of adjusting, providing a higher voltage than required to operate the fan motor at the desired speed.
