Natural Ventilation and Commercial Control | Titan Products

Designed to ventilate and cool spaces, natural ventilation is one of the most energy efficient methods to control a buildings comfort conditions. By aiding natural airflow through a space, energy costs are kept to a minimum while productivity levels within the controlled space are maximised by maintaining the desired temperature and Co2 levels.

ADM-APN017-EN (10/05): CO2-based demand-controlled ...

concentration (Co) of carbon dioxide seldom varies by more than 100 ppm from the nominal value.* Because of this and in lieu of installing an outdoor CO2 sensor, most designers use either a one-time reading of the outdoor CO2 concentration at the building site or a conservative value from historical readings. This simplifies control,

Easy solutions for indoor air problems at schools - Vallox

Carbon dioxide -based control is an excellent means to control ventilation automatically based on the need in premises where the number of occupants varies. The carbon dioxide -based control identifies when people enter the premises and enhances the efficiency of ventilation almost steplessly. This way, ventilation is not too efficient when there are only a few people present in the classroom ...

Carbon Dioxide (CO2) Safety Program

Carbon dioxide (CO2) is a “sleeper hazard;” very little information outside scientific literature has been published to help facilities understand CO2 health effects and control CO2 exposures. This Carbon Dioxide Safety Program is designed to fill this gap. Breathing concentrations of 30% CO2, even with 70% oxygen, leads to unconsciousness in 30 seconds Your facility may have been doing ...

CO2-2 Temperature, Humidity & CO Control

Carbon Dioxide is present in relatively low quantities (about 350 ppm) in your normal everyday plant growth can be increased and accelerated if the level of CO2 is increased to 1000-1500 ppm. For this reason, we designed the CO2-2. The CO2-2 CO2 control system was designed to be used for both compressed CO2 cylinders, and CO2 generators. The CO2 receptacle is 120 volts. It can run any ...

CO2 In a Classroom – Indoor Air Quality

In Austria, building legislations state that CO2 amounts in a classroom should definitely not exceed 1,400 ppm. Normal outdoor CO2 concentration is in the range of 250-400 ppm; between 400 and 1000 ppm can be found in enclosed spaces that have good air exchange (ppm means “parts per million” and measures the mass of a chemical). Upwards of 1000ppm, causes drowsiness, and beyond 2000 ppm ...

2 Control In School Classrooms 1 of 3 CO ... CO2 Sensors will automatically regulate fresh air delivery so that over-ventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ...

Inadequate Ventilation and High CO2 Levels

Inadequate ventilation can lead to the build-up of small amounts of contaminants which are difficult to identify and test, so carbon dioxide (CO2) levels are used as an indicator of adequate ventilation in a room. Carbon dioxide is released by combustion of fuels and every time we breathe. It is normally measured at 300-350 ppm (parts per million) in the atmosphere. The legal exposure limit is a
