Abstract
A control system, comprising one or more smoke sensors, each configured to measure a level of smoke at a location within a building and to output a smoke level signal based at least in part upon the measured level of smoke. A controller configured to receive the smoke level signals and to control an operation of one or more energy recovery ventilation systems in a first mode of operation to recover energy when the smoke level signal is below a predetermined value and in a second mode of operation to evacuate smoke when the smoke level signal is above the predetermined value.
Claims21
A control system, comprising:
- one or more smoke sensors, each configured to measure a level of smoke at a location within a building and to output a smoke level signal based at least in part upon the measured level of smoke;
- and
- a controller configured to receive the smoke level signals and to control an operation of one or more energy recovery ventilation systems in a first mode of operation to recover energy when the smoke level signal is below a predetermined value and in a second mode of operation to evacuate smoke when the smoke level signal is above the predetermined value.
9-19. (canceled)
A system, comprising:
- a first smoke sensor configured to measure a first level of smoke at a first location within a building and to output a first smoke level signal based at least in part upon the first measured level of smoke;
- a second smoke sensors configured to measure a second level of smoke at a second location within a building and to output a second smoke level signal based at least in part upon the second measured level of smoke;
- and
- a controller configured to receive the first smoke level signal and the second smoke level signal and to control an operation a first energy recovery ventilation system in a first mode of operation to recover energy when the first smoke level signal is below a predetermined value and to control an operation a second energy recovery ventilation system in a second mode of operation to evacuate smoke when the second smoke level signal is above the predetermined value.
A system, comprising:
- a smoke sensor configured to measure a level of smoke at a location within a building and to output a smoke level signal based at least in part upon the first measured level of smoke;
- and
- a controller configured to receive the smoke level signal and to control an operation an energy recovery ventilation system in a first mode of operation that includes operation of a first item of equipment, to recover energy when the smoke level signal is below a predetermined value and to control an operation the energy recovery ventilation system in a second mode of operation that includes operation of a second item of equipment, to evacuate smoke when the smoke level signal is above the predetermined value.
