Check the indoor CO2more
CO2 Controller & Monitor
Life “CO 2” concentration is “visible”
safety! Relief! Decided version of energy conservation · comfortable society realization!
Measure the CO2 concentration and let us know the CO2 level! Send the data to the outside.
Control of HVAC (heating, ventilation, air conditioning) system by relay. Prevents health damage in advance (alarm, ventilation fan, air conditioning equipment, air conditioner, air purifier etc)
What is CO2 controller / monitor?
CO2 controller / monitor “is the first CO2 measuring instrument in Japan that we are continuing to develop. “CO2 controller” measures the CO2 concentration in the room and notifies the CO2 level so that you can have a comfortable and energy-saving living space. In recent high air-tight buildings, health damage caused by indoor CO2 concentration is becoming a problem.
- Schools / libraries / educational facilities
- Detached house / apartment house
- Hospitals · Aged health · Long-term care facilities
- Office / office space
- Hotels & Accommodations
- Shops, restaurants, concert halls, commercial facilities
Why do you need CO2 control?
If you are in a space with a high CO2 concentration for a long time, health damage may occur.
As shown in the figure below, as the concentration of CO2 in the room rises, it is said that it gradually affects the human body. Recommended value set by “American Heating Cooling and Air Conditioning Association” is 1000 ppm or less. It is pointed out that sleepiness and discomfort may occur when this standard value is exceeded.
Even in Japan, the following standards are set for the CO2 concentration in the living space, and from the viewpoint of compliance with laws and regulations, it is necessary to adjust the indoor CO2 concentration not to exceed 1000 ppm.
On the other hand, the low concentration of CO2 in the room is not good. The lower CO2 concentration in the room means that the lower the CO2 concentration in the room is, the more outside air is taken in. In the summer and winter, the air conditioning load increases, resulting in far less energy saving. For example, if the ventilation equipment is operated more than necessary on a hot summer day, a large amount of outside hot air will be taken into the room and the CO2 concentration will decrease but the room temperature will rise. In order to maintain the indoor temperature constant, the air conditioner will be forced to fully operate automatically, resulting in a drastic rise in electricity charges.
In other words, as mentioned above, keeping the indoor CO2 concentration at an appropriate level (800 ppm to 1000 ppm) is required for energy-saving and comfortable interior space.
External output function of CO2 controller (Relay · Analog · Digital)
The CO2 controller does not only measure and display indoor CO2 concentration. When the measured value exceeds the specified amount, the relay function operates to control the externally connected equipment.
By operating the ventilation equipment (ventilation fan, total heat exchanger, etc.) connected to the controller as shown above, it is possible to adjust the CO2 concentration in the room and to turn off the alarm machine. If you use the data logger function, you can record the increase / decrease of carbon dioxide concentration, temperature and humidity on the spot by inserting a Micro-SD card.
With analog output (4-20 mA, 0 – 10 V), proportional control of VAV and data transmission / recording to the central monitoring room are possible. Furthermore, it is also possible to send and record data sequentially by digital output such as RS232C or Modbus (RS485).
In other words, by introducing “CO2 controller / monitor”, it is possible to prevent health damage and to spend energy saving and comfortable environment.
A lineup of fulfillment for use!
At our company, we are developing a variety of CO2 controllers / monitors that are rich in variety according to customer’s needs. The latest type NMA-PR-RB is a built-in Bluetooth type, requiring no electric wiring work and SA-K 03 specialized for facility horticulture has two-stage control of CO 2 concentration in a vinyl house (high concentration, low Concentration) is possible. In addition, by combining with the pump unit SA-P01 etc., it can respond to any needs.
