but what if the ac gets frozen
Sure ... once the thermostat senses the cooler air, it will shut down the AC unit anyway.
Yes, it is not efficient to have the air conditioning on while the windows are open because it can waste energy and increase electricity costs.
When you use the recirculate option the air conditioning will cool better since it will be further cooling the already cooler air inside the cabin, while the fresh air option will always be using the warmer air from outside.
To properly ventilate a room with windows open and the air conditioning on, you should open windows on opposite sides of the room to create cross ventilation. This allows fresh air to come in and stale air to go out. The air conditioning helps to maintain a comfortable temperature while the fresh air circulates.
Spot coolers are an excellent way to cool down an area that either has no air conditioning or needs to be cooler than can be achieved with regular air conditioning. Typically the cost of a spot cooler is in the range of $900 to $1100 dollars. While the initial investment is greater, the spot cooler is typically the more energy efficient choice.
Leaving a window open while using air conditioning is not recommended because it can let warm air in and reduce the efficiency of the cooling system. It is best to keep windows closed to maximize the effectiveness of the air conditioning.
Simply: If it is colder outside than inside then opening the windows will give cooling to the space. If lots of air is entering then the air conditioning system may not have much effect on temperature. However in some cases this will not be true: Air conditioning systems remove both heat and usually water from the air. If the humidity in the outside air is high, the humid air entering will cause the air conditioner to use all its power on removing water from the air leaving none for removing heat. PS It is commonly believed that one should not open the windows, as this will result in "cooling down the entire world". However with a limited capacity air conditioning system, this will not be a problem.
The temperature inside the car is higher than outside
Actually, Casement windows DO open. Casement windows are really any window that is hinged. Some Casement windows are designed to open to the outside while others are designed to open inwards. Jim
Privacy tint on house windows provides increased privacy by reducing visibility from the outside while still allowing natural light to enter the home. It also helps to block harmful UV rays, reduce glare, and improve energy efficiency by keeping the interior cooler in the summer and warmer in the winter.
== == The air temp outside is cooler than the air inside the car, so moisture forms on the inside of the glass surface. If this happens while you are driving, you may be adding to the problem by your breathing. Your breath contains a lot of moisture and it lands on the inside of the car windows. Solution............ run the defroster fan on hot and direct the warm air onto the windshield, and the side windows, PLUS open the windows at least an inch to let the dampness out of the car.
Your body will be in motion while seeing outside the windows of an airplane. Due to the speed of the airplane, you are moving with the aircraft even though you may feel stationary inside the cabin. It is similar to being in a car – your body is in motion along with the vehicle.
To effectively cool your home during the summer, you can use the air conditioning to lower the temperature and then open the upstairs windows to allow for cross ventilation. This will help circulate the cool air throughout the house and maintain a comfortable temperature.
