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.
Claims19
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.
A method of controlling operation of an energy recovery ventilation system, comprising:
- measuring a smoke level with a smoke sensor;
- receiving a smoke signal at a processor from the smoke sensor, wherein said smoke signal is based at least in part on the smoke level;
- and
- controlling an operation of an energy recovery ventilation system using the processor, based at least in part on the smoke signal;
- wherein the controlling is based at least in part on a predetermined sequence.
An article, comprising:
- a signal bearing medium comprising machine-readable instructions stored thereon, which, if executed by one or more processors, operatively enable a computing device to calculate an effectiveness of an air handling system by:
- measuring a smoke level with a smoke sensor;
- receiving a smoke signal at one or more of the processors from the smoke sensor, wherein the smoke signal is based at least in part on the smoke level;
- and
- controlling an operation of an energy recovery ventilation system using the processor, based at least in part on the smoke signal;
- wherein the controlling is based at least in part on a predetermined sequence.
