Abstract

An air conditioning appliance having a safety device. The safety device preferably communicates with at least one sensor that is configured to detect an undesirable condition. If an undesirable condition is detected, then the operation of the air conditioning appliance can be modified as needed for safety.

Claims

1. A method of providing an air conditioning system with a safety feature, comprising:

providing an air conditioning system having an advanced safety feature, comprising;

an air conditioning housing;

an evaporator configured to extract heat from surrounding air;

a condenser configured to convert vapor to liquid;

a compressor configured to increase the pressure of a gas;

a refrigerant circulating through the air conditioning system;

at least one of a drain pan positioned under the air conditioning housing and a P-Trap formed by a drain pipe extending from the air conditioning housing;

a sensor disposed in at least one of the drain pan and the drain pipe, the sensor being configured to detect liquid;

a controller in communication with the sensor and the air conditioning system, the controller further comprising;

an alert module configured to send an alert if the sensor detects the liquid, wherein the alert is at least one of a text message, a voice call, an email, and an audio alert through a wireless speaker;

a bypass message module configured to receive a bypass message after the alert is generated prior to the controller stopping operation of the air conditioning system;

an operation termination module configured to stop operation of the air conditioning system if, after generating the alert, the bypass message module does not receive the bypass message within a predetermined amount of time and if the sensor still detects the liquid; and

an override message module configured to restart operation of the air conditioning system after the operation termination module has stopped operation of the air conditioning system when an override message is received;

providing a ventilation duct in fluid communication with the air conditioning system;

positioning a carbon monoxide sensor within the ventilation duct, the carbon monoxide sensor adapted to detect a carbon monoxide level of an air in the ventilation duct, and wherein the controller is in communication with the carbon monoxide sensor;

the user selecting a type of alert to be sent, the type of alert being the at least one of the text message, the voice call, the email, and the audio alert through the wireless speaker;

sending a carbon monoxide alert by the alert module if the carbon monoxide sensor detects a predetermined level of carbon monoxide in the air of the ventilation duct, wherein the carbon monoxide alert is the at least one of a text message, a voice call, an email, and an audio alert through a wireless speaker;

monitoring by the bypass message module and the override message module for receipt of at least one of a carbon monoxide bypass message and a carbon monoxide override message after generation of the carbon monoxide alert; and

stopping operation of the air conditioning system by the operation termination module if the carbon monoxide sensor continues to detect that the carbon monoxide level of the air is equal to or greater than the predetermined level and the carbon monoxide bypass message is not received within a predetermined amount of time after the carbon monoxide sensor first detects that the carbon monoxide level of the air is equal to or greater than the predetermined level.

2. The method of claim 1, wherein the step of providing an air conditioning system further comprises providing a relay shield, wherein the controller is in communication with the relay shield, and sending a termination signal to the relay shield which then opens a relay switch thereon to break power to the air conditioning system.

3. The method of claim 1, wherein the step of providing an air conditioning system further comprises the sensor being disposed on the drain pan, and providing a second sensor on the drain pipe, the controller being in communication with the second sensor, the alert module being configured to send an alert if the second sensor detects the liquid.

4. The method of claim 1, wherein the step of monitoring by the controller further comprises the bypass message being a code that the user provides to the bypass message module via at least one of a text message and an email.

5. The method of claim 4, further comprising the code which can be submitted to the bypass message module by the user and which is located on a portion of the at least one of the drain pan and the drain pipe.

6. The method of claim 1, wherein the step of providing the controller further comprises the controller communicating with at least one of a server.

7. The method of claim 1, wherein the sensor is a normally closed switch that is configured to open upon detecting the liquid.

8. The method of claim 1, further comprising the step of:

after stopping operation of the air conditioning unit, monitoring by the override message module for receipt of the override message, wherein the controller is configured to resume operation of the air conditioning system upon receiving the override message.
