The specific application of displacement ventilation

Air conditioning energy saving and indoor air quality is the current HVAC community facing two major issues, and replacement ventilation can be a better solution to a certain extent to these two problems.

(1) In order to obtain the same temperature in the work area, the replacement ventilation system requires a higher supply air temperature than the mixed ventilation, which provides the possibility of utilizing low-grade energy as well as natural ventilation cooling for a longer period of time in a year to achieve the effect of energy saving. According to relevant statistics, replacement ventilation can save 20% to 50% of the cooling consumption compared with mixed ventilation.

(2) Replacement ventilation can be more effective control of C02 and other pollutants in the work area. Its ventilation efficiency coefficient is greater than that of mixed ventilation, so that the purpose of improving indoor air quality can be achieved.
