Analysis of Indoor Air Quality for the Split-Type Air Conditioner with Air Change Function in an Office Environment

Abstract:

As Taiwan is located in subtropical zone, it has a high temperature and high humidity climate, and the mean annual relative humidity is higher than 70%. Therefore, the air conditioning products are daily necessities. The split-type air conditioner was used extensive. However, as limited to its mechanical structure, most of split-type air conditioners lack the air change function, so that the air quality in the air conditioned space declines. At present, the split-type air conditioner with air change function has been developed and commercialized. This paper attempts to experiment tested the air conditioner in an office work environment, and measured the concentration of CO₂ under different conditions, so as to validate the fitness of this equipment in office work environment. It is found that after two hours, the CO₂ concentration have been over 2600 ppm in the office without outdoor air inlet. The split-type air conditioner with air change function can reduce the CO₂ concentration and accumulate, the indoor CO₂ concentration can maintain 500 ppm when one person within office environment.
