Abstract

A system for neutralizing odors present in exhaust air extracted from a space via an exhaust air duct, the system including an air intake chamber; an air intake means for bringing environmental air into the air intake chamber and a corona chamber in air flow communication with the air intake chamber, and adapted to receive air from the air intake chamber. The corona chamber includes at least two spaced apart and perforated corona plates with perforated stainless steel mesh providing a dielectric medium into which an electrical spark voltage is provided to generate ozone from oxygen present in the environmental air to thereby transform the environmental air into ozone-rich air. A reaction chamber is also provided and adapted to receive the exhaust air and the ozone rich air allowing the mixing of the exhaust air and the ozone-rich air to thereby neutralize the odors before being discharged via an air outlet into the environment.

Abstract

A method for monitoring the concentration of a gas in an enclosed space is provided. A gas is injected into the space, by a gas injection system. The concentration of the gas is measured using a gas sensor. The concentration is compared with predetermined limits, and the gas injection system is shut off if the concentration is above one of the predetermined limits. In addition, hardware, software, and signal control elements which perform the monitoring, are continuously monitored for faults, and if a fault is detected, the gas injection system is shut off.

Abstract

A system and method for monitoring the concentration of a gas in an enclosed space into which the gas is being injected by a gas injection system. The system includes means for carrying out the method that includes measuring a parameter indicative of gas concentration using a gas sensor, comparing the parameter with a predetermined limit value of the parameter using a microprocessor, and if the parameter is greater than the predetermined limit value then activating a shut-off of the gas injection system. Furthermore, continuously monitoring at least one of a hardware element, a software function and a control signal used to carry out the method to identify faults in at least one of the hardware element, the software function and the control signal; and if a fault is detected activating the shut-off of the gas injection system.
