Abstract
A heating ventilation and air conditioning (HVAC) control system. The HVAC control system includes a sensor that detects a refrigerant released from an HVAC system and emits a signal indicative of the detection. The HVAC control system also includes a switch that blocks a flow of electricity to an enclosed space and a controller that receives the signal from the sensor and activates the switch to block the flow of electricity in response to detection of the refrigerant.
Claims21
A heating, ventilation, and air conditioning (HVAC) control system, comprising:
- a sensor configured to detect a refrigerant released from a HVAC system and to emit a signal indicative of the detection;
- a switch configured to block a flow of electricity to an enclosed space;
- and
- a controller configured to receive the signal from the sensor and activate the switch to block the flow of electricity in response to detection of the refrigerant.
A heating, ventilation, and air conditioning (HVAC) control system, comprising:
- a sensor configured to detect a refrigerant released from an HVAC system and to emit a signal indicative of the detection;
- a valve configured to block a flow of a fluid to an enclosed space;
- and
- a controller configured to receive the signal from the sensor and activate the valve to block the flow of the fluid in response to detection of the refrigerant.
A heating ventilation and air conditioning (HVAC) control system, comprising:
- a sensor configured to detect a refrigerant released from an HVAC system and to emit a signal indicative of the detection;
- an electronic device;
- and
