Abstract
A method of generating an alarm based on temperature conditions within an enclosed space. The method includes receiving, by a processor of a heating, ventilation, and air conditioning (HVAC) system, operating-condition information of the HVAC system, determining, by the processor from the received operating-condition information, whether temperature within the enclosed space is approaching a setpoint temperature. Responsive to a determination that the temperature within the enclosed space has failed to approach the setpoint temperature, determining by the processor, whether anomaly conditions exist and responsive to a determination that the anomaly conditions do not exist, generating the alarm.
Claims20
A method of generating a master service alarm based on temperature conditions within an enclosed space conditioned by a heating, ventilation, and air conditioning (HVAC) system, the method comprising:
- receiving, by a processor of the HVAC system, information for operating the HVAC system in at least one of a cooling mode and a heating mode;
- determining, by the processor of the HVAC system from the received information, whether air temperature within the enclosed space is approaching a target temperature of the HVAC system indicative of an existing or future comfort violation of a user desired temperature setting;
- responsive to a determination that the air temperature within the enclosed space has failed to approach the target temperature, determining by the processor of the HVAC system, whether anomaly conditions exist;
- responsive to a determination that the anomaly conditions do not exist, generating, by the processor, the master service alarm indicating that the HVAC system is in need of service;
- and
- responsive to a determination that the anomaly conditions exist, no alarm is generated.
A system comprising:
- a processor of a heating, ventilation, and air conditioning (HVAC) system;
- at least one server configured to communicate with the processor of the HVAC system via a wireless network;
- wherein the processor of the HVAC system is configured to:
- receive information for operating the HVAC system in at least one of a cooling mode and a heating mode;
- determine whether air temperature within an enclosed space is approaching a target temperature of the HVAC system indicative of an existing or future comfort violation of a user desired temperature setting;
- responsive to a determination that the air temperature within the enclosed space has failed to approach the target temperature, determine whether anomaly conditions exist;
- responsive to a determination that the anomaly conditions do not exist, generate a master service alarm indicating that the HVAC system is in need of service;
- and
- responsive to a determination that the anomaly conditions exist, no alarm is generated.
