초록

Demand ventilation protocols can address the issue of sensor failure while still providing desirable levels of energy conservation. An occupancy indicator such as a sensor can be monitored. If the sensor reading is determined to be incorrect, unexpected or otherwise erroneous, the ventilation system can provide an amount of fresh air sufficient for adequate ventilation without over-ventilating the building.

청구항

We claim: 1. A method of controlling ventilation of an environment, the method comprising the steps of:monitoring an output of an occupancy indicator of the environment;providing a first amount of fresh air to the environment if the occupancy indicator is deemed to be providing an output that is valid, wherein the first amount of fresh air is dependent, at least in part, on the valid output of the occupancy indicator;if the occupancy indicator is deemed to be providing an output that is erroneous, always providing a fixed second amount of fresh air to th...
