You can't expect more than a 20- to 25-degree differential with a standard home central AC unit. Older, less-efficient units will struggle to reduce indoor temps even the 20 degrees below outdoor temps.
An air conditioner regulates the temperature of a room by removing heat from the air inside and releasing it outside, resulting in a cooler indoor environment.
It is not advisable to run the air conditioner with the windows open, even when the outside temperature is cooler. This can waste energy and reduce the efficiency of the air conditioner. It is more efficient to keep windows closed when using the air conditioner to maintain a consistent temperature inside.
The outdoor portion of the central ac unit is what gives up the heat from indoors, so it has to be outside. For a more thorough explanation see the question: How does air conditioning work.
No, an air conditioner does not bring in outside air. It cools and circulates the air already inside a building.
A split air conditioner is a unit where the condensing unit is outside and the evaporator is inside.
An air conditioner uses refrigerant to transfer heat from one place to another, such as from inside the home to the outside.
It changes based on vehicle, outside temp, and desired inside temp. Pressuse depends on ambient temperature, the higher the temp, the greater the pressure
If your air conditioner is running outside by not blowing cold air inside through your vent, your indoor coil is frozen. You will need to turn everything off and allow the unit to thaw out.
An air conditioner operates similarly to a refrigerator by transferring thermal energy from inside a room to the outside. This is achieved through the use of a refrigeration cycle that absorbs heat from inside the room and releases it outside, cooling the indoor space in the process.
The temperature inside the house is 31 degrees higher than the outside temperature.
Whatever temperature you are comfortable, 78 F is recommended by utilities in summer.
