Indoor Air Pollution and Inter-Room Pollutant Transport Due to Unvented Kerosene-Fired Space Heaters

摘要

Two kerosene-fired space heaters, one white-flame convective and one blue-flame radiant, were operated in the master bedroom of an unoccupied house under several simulated use conditions. Tests were conducted with the bedroom door and outside window closed, with the door closed and the window open 2.5 cm, with the door open 2.5 cm and the window closed, and with the door wide open and the window closed. The heaters were operated until an 8 exp 0 C temperature rise was achieved in the room. Increases in bedroom concentrations of CO, CO sub 2 , NO, NO sub 2 , and O sub 2 are reported. The increases in CO sub 2 levels ranged from 2440 to 5440 ppM while the increases in NO sub 2 levels ranged from 0.12 to 0.60 ppM. In addition, inter-room pollutant transport rates are reported for tests conducted with the window closed. While inter-room pollutant transport rates were less than 10 m exp 3 /h with the bedroom door closed, they were 30 +- 10 m exp 3 /h with the bedroom door open 2.5 cm, and ranged from 190 m exp 3 /h to 3400 m exp 3 /h with the door fully open (74 cm). 6 references, 1 figure.
