An Investigation and Analysis on Indoor Environment of Typical Office with Self-Regulation Inlets VAV System

Abstract:

Indoor environment of VAV system was paid more increasing attention, besides the energy saving, zone temperature control of VAV system. In this paper, using in-site testing and analysis, some experiments were conducted on indoor environment of the typical office with self-regulating inlet VAV system. The results showed the temperature and relative humidity of the selected office were in the range of 22.8 °C~24.5°C and 27.0%~35.0%, respectively. The maximum volume of total supply airflow is 816 m³/h, while the minimum one is 557 m³/h. The concentration of carbon dioxide ranged from 0.0596% to 0.0873% (v/v). The calculated maximum value of temperature uniformity coefficient was 0.026 that indicated the distribution of indoor air is uniformity. So this VAV system used in the office building provided a good indoor environment to meet the satisfaction of the office staff.
