The Research Of The HVAC Design Methods For The Specific Objects

At present, ventilation air condition adopts the way of lumped-parameter to process the design, the air-conditioning effect will be evaluated by the average parameter and the comfortability and the requirement to the air quality could not be well met. For the design drawback of the traditional air-conditioner, Airpak software is used to process the data simulation of the indoor's fluid field, temperature field, velocity field and air age field to the 'wind sent from the tip and returned from the bottom' 'wind sent from the side and returned from the bottom' and 'replacement ventilation' these three different types of wind return of the computer cluster. Through the analysis of the temperature field, velocity field and air age field, using the indoor atmosphere quality evaluation method and the evaluation index of the human comfortability, the air organizing method will be confirmed for the areas where the people always visit to prove that the replacement ventilation not only meets the requirement of the human comforability, but also the good indoor air quality will be acquired, and that is the best way of wind sending and return method .
