Ideal airconditionerسیستم تهویه ایده ال

استاد عزیر من از سیستم تهویه اتاقش که خیلی پر سر و صداست کاملا راضی است؛ چون باعث کوتاه تر شدن جلسات می شود.

My dear professor is very happy with the air condition system in his room; since it is too noisy and encourages the PhD students to leave the meeting as soon as possible.
