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
An air conditioner exhaust vent should typically be closed during normal operation to ensure optimal cooling efficiency. Keeping it closed helps maintain the desired indoor temperature by preventing warm air from entering the cooled space. However, if the system is being used in a mode that requires ventilation, such as during mild weather, it may be appropriate to open it temporarily. Always refer to the manufacturer's guidelines for specific recommendations.
An air conditioner typically operates as a closed loop system. In this system, the refrigerant circulates within a sealed loop, absorbing heat from indoors and releasing it outdoors. This design allows for efficient heat transfer and temperature regulation without the need for external air exchange, maintaining controlled indoor conditions.
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.
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.
A Reverse cycle Air conditioner is MUCH more efficient than resistance heating. It is called a heat pump, and requires that the Evaporator and Condenser coils of a Closed Refrigerant System be reversed.

Please clarify what set you are talking about. There are several sets of numbers. Also, "closed under..." should be followed by an operation; "natural" is not an operation.
keep it closed the windows .but if need fresh air from outside , open the windows.
The exhaust from the car in the closed garage killed him.
Don't do this unless you have a proven way to vent the engine exhaust to the outside. Engine exhaust contains carbon dioxide which is deadly to people. It makes you pass out and then kills you. People have died from sitting in a closed car outside.
A set can be closed or not closed, not an individual element, such as zero. Furthermore, closure depends on the operation under consideration.
Yes, the Canadian Football League (CFL) is not closed under union operation.
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.
In a four-stroke engine, the intake valve opens in the intake stroke, allowing air-fuel mixture to enter, while the exhaust valve remains closed. During the compression stroke, both valves stay closed to build pressure. In the power stroke, the fuel ignites, pushing the piston down, with both valves still closed to retain pressure. Finally, in the exhaust stroke, the exhaust valve opens, allowing gases to escape, while the intake valve stays shut. This cycle repeats continuously, ensuring efficient engine operation.
In a four-stroke engine, both the intake and exhaust valves are closed during the power stroke, allowing for maximum pressure to build from the combustion of the air-fuel mixture. Similarly, during the exhaust stroke, both valves are also closed momentarily after the power stroke until the piston moves up to expel the exhaust gases. However, the intake valve opens before the power stroke begins, and the exhaust valve opens at the end of the power stroke to facilitate the exhaust process. Thus, while both valves are closed during the power and exhaust strokes themselves, they open at specific times in the cycle.
