Not very often. probably every hour it should come on for about 20 minutes if that.
35 degrees Celsius.
65 degrees Fahrenheit = 18.3 degrees Celsius.
The answer depends on which field of science you are referring to. If you're referring to the human body, it's 98.6 degrees F. If you're talking about the International Standard Atmosphere, it's 15 degrees C or 59 degrees F. In Physics, they use 273.15 degrees K (or 0 degrees C), and in Chemistry, they use 298.15 degrees K (or 25 degrees C). If you're just talking about cooling your home, usually yes, 72-74 degrees Fahrenheit is a comfortable temperature, although depending on what the outside temperature is, it can be expensive to achieve.
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.
in central ac we use chiller to cool the water which is circulated throughout the building . by blowing air over the cooled water tubes the air got cooled. in night time inplace of cold water FM chiller , hot water is circulated which make the air hot.
Central air conditioning systems do not use water for cooling. Instead, they use refrigerants to transfer heat from inside a building to the outside.
It depends on the year, make and model plus the outside temperature but between 37 to 48 degrees...
no it is not because you are just cooling yourself off. DDDDDDDDDDDDDUUUUUUUUUUUUUHHHHHHHHHHHHHHHHHHHHHHHHH
Central air conditioning systems are designed to provide ventilation by bringing in outside air. Leaving a window open would tend to defeat the cooling effect.
Installing an outside central air unit in a residential property provides efficient cooling, better air quality, and increased home value. It also allows for consistent temperature control and can lower energy costs compared to window units.
A heat pump generally has a max temperature change of 20 degrees F. If air entering the return duct is 90, it will not be cooler than 70 on the discharge side, Below 60, it is working against the insulation and air infiltration into the house. It is an air conditioner, not a deep freeze. Remember that a heat pump either dumps heat outside to cool a house, or picks up heat from outside to heat the house. If it is 100 degrees outside, it is hard to dump heat. Below 35, it is hard to pick up heat. At an outside temp of 59 degrees, it should work for either- but nobody needs cooling when it is 59 degrees outside. Open a window, already!.
Not necessarily. When it is 40 degrees Celsius outside, it is sweltering!
Still 54 degrees if the 18 degree drop is inside!
No, air conditioners do not bring in outside air when cooling a room. They recirculate and cool the air already inside the room.
The temperature at which water freezes outside is 32 degrees Fahrenheit or 0 degrees Celsius.
125 degrees
