It takes the temperature nonuniformity coefficient, speed nonuniformity coefficient, and energy utilization coefficient as the air current organization evaluating indicator. The result shows: the small the blast angle, the more uniformity of indoor temperature and speed, the better energy utilization under the same air volume; the large the air volume, the more uniformity of indoor temperature and speed, the better energy utilization under the same blast angle. 【中文關鍵詞】 室內機; 送風參數; 氣流組織; 數值模擬【英文關鍵詞】 Indoor unit; Supply parameters; Air current distribution; Numerical simulatio
