A cold air dryer works by cooling down the compressed air, causing the moisture in the air to condense into liquid form. The liquid moisture is then separated and removed from the air stream, resulting in dry compressed air.
When compressed air is released, it tends to be cold because the expansion of the air causes it to cool down.
A hair dryer blows hot air out.
When you use a compressed air can, the rapid release of pressurized air causes it to expand quickly. This expansion lowers the temperature of the air, making the can feel cold to the touch.
One common reason for a gas dryer getting hot then turning cold is a blocked vent or exhaust system. This can cause the dryer to overheat and then shut off to prevent a fire. Another possibility is a malfunctioning cycling thermostat or gas valve that needs to be replaced. It is recommended to have a professional technician inspect and repair the dryer to ensure safe operation.
The cold setting on a hair dryer is for cooling and setting a curl. For example, if you use a round brush to curl your hair and then blast it with the hot setting on your blow dryer- before removing the brush, blast it with the cool setting. This will cool the curl and set it and the curl will last longer.
An air dryer can be effective in reducing moisture in the air during winter, but its effectiveness may be limited in very cold temperatures. It can help to maintain a comfortable level of humidity indoors, but additional measures may be needed in extremely dry conditions.
Compressed air leaves a cooling sensation because when on feels the air on his body part, there is some moisture content on the skin and when air strikes, it makes the moisture content to evaporate by absorbing the nearby heat from the skin thus making a cooling sensation.

An oven ought to be vented. The purpose of the range hood is to pull out the water that bakes out of the food every bit as much as to pull out grease, smoke and strong odors. Both the oven and the dryer dump moisture into the air. If that moisture is not vented out of the house it will condense on cold walls and windows. Moisture grows mold and causes other problems. Of the two appliances, the dryer dumps many more times the volume of water vapor into the air. If both appliances are fueled by natural gas, burning the gas will also produce water vapor. Again, the oven does not use nearly a fraction of the gas that the dryer uses so the vapor can be dumped into the house without too much problem. Many houses during the winter are drier than most deserts because the moisture content of cold outside air is very low. When that air is heated, its moisture content remains the same but its relative humidity drops. If your windows sweat, that is a good sign that excessive moisture is in your house and you need to be venting your appliances or running the exhaust fan during hot showers.
Moisture in the air condenses on the cold surfaces.

no
fog
on some models yes this is to remove the moisture from the air to help keep your windows free of condensationm when it is cold outside
The cold causes the moisture in your breath to condense, making it visible.
Tumble dryer condenser kits are design to fit most tumble dryer models and were created to assist you in condensing the hot air your dryer produces. By condensing the air with cold water you can place the dryer in a room that does not have a window or opening for a vent.
