CO2 Control In School Classrooms - AirTest Technologies

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 ideal way to control ventilation based on ...

How Cooling With CO2 works - TotalTemp Technologies

It is very important to design CO2 supply and control systems so that the cross section of the plumbing line never (expands and subsequently) restricts. This will invariably result in dry ice blockage. Due to the lower costs to capture and compress CO 2, it is generally commercially cheaper and for that reason can be a preferable coolant.
