Should air conditioner exhaust be open or closed during operation?

It should remain closed initially while the air con cools down the room, then opened after the room is cool. This allows a small amount of fresh air to be brought inside to stop the air from getting stale if it is open when the air con is first turned on it just takes a bit longer to cool down the room

What is the difference between blow off valves and waste gates?
the bov allows excess boost/pressure to out of the intake when the throttle body is closed. A wastegate is on the exhaust side and allows exhaust gas to bypass the turbocharger at high rpm, this reduces the restriction of airflow by the turbo.
What is the basic principle of the operation of an eye-bolt?
They are designed to have a rope or cable fed through the ring in order to lift objects. The ring can be drop forged (one single piece, the eye being entirely closed) or bent to form a loop. Bent eye bolts should only be used in light duty applications and should never be used to execute angular lifts.
Why reverse cycle airconditioning is not more effective in winter?

Why the isolator should not closed with load?
Isolation switches can be closed with loads connected. The isolation switch should not be opened under load unless the switch is load rated. This information can be found on the isolation switch's cover as to the amount of current that can be safely interrupted.
What will happen if relief valve in hydraulic circuit fails?

They form a commutative ring in which the primary operation is addition and the secondary operation is multiplication. However, it is not a field because it is not closed under division by a non-zero element.
