Iâ??m growing in an 8 X 18 feet room with 3 1000W HPS lamp. Iâ??m having problem keeping temperature low and was wondering how effective cool tubes really are?

I was taking my fresh air from another room in the house that is always at 18 degrees Celsius and it does not seem to be enough so Iâ??m presently taking fresh air from outside but I need at least -15 Celsius to keep my room at desired 24 Celsius â?¦ Pretty impossible in June !!

So if anyone can give me a straight answer as to how effective these cool tubes really are, it would be greatly appreciated.
