Natural gas heater CO2 sampling roomLiquefied gas heaters will produce CO2 during use. In a closed environment, excessive CO2 concentration can cause human poisoning. According to the requirements of the standard "ANSI Z21.103-2017 Odorless Portable Gas-fired Camp Heater for Indoor and Outdoor Use", liquefied gas heaters The heater can use a liquefied gas heater CO2 emission chamber to detect its CO2 concentration.
Main parameters of CO2 emission chamber of liquefied gas heater:
Volume inside the chamber: 14m³ or customized as required
Temperature range: (15~100)℃
Humidity range: (30~60)%
Air flow speed in the chamber: (0.1~0.3)m/s
Air replacement rate: (0.2~3)m³/h
Sealing: When there is an overpressure of 1000Pa, gas leakage is less than 1*10^-3mm/min, and the gas flow difference between the inlet and outlet is less than 1%
Thermal insulation: The walls and doors of the climate chamber should have effective thermal insulation.
Monitoring parameters: Monitor and display the temperature and humidity in the cabin, air supply and exhaust volume, power on and off time, and working time. The data can be transferred and stored.
The CO2 emission chamber of the liquefied gas heater meets the standards:
ANSI Z21.103-2017 Odorless portable gas-fired camp heaters for indoor and outdoor use
Emission chamber requirements:
The maximum temperature in walls and in overhead combustible construction shall not exceed 117°F (47°C) above room temperature and in floors when heaters are tested under the manufacturer's species approval under the test conditions described herein. Room temperature 90℉(32℃).
Test Methods:
1. Gradually block the exhaust pipe until the gas heating furnace goes out.
2. Block the exhaust pipe so that the gas heating furnace is in a critical state where it can just be ignited, from cold start to thermal equilibrium state.
3. Gradually reduce the working voltage of the fan until the gas heating furnace goes out.
4. Under the minimum operating voltage of the fan, the gas heating furnace starts from cold to the thermal equilibrium state.
If you have any questions about the selection of the CO2 emission chamber of the liquefied gas heater, you can visit the official website of "huanyi Instruments" and consult relevant technical personnel.
