The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment. [61]
Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required.

An owner's manual (also called an instruction manual or a user guide) is an instructional book or booklet that is supplied with almost all technologically advanced consumer products such as vehicles, home appliances and computer peripherals.
In the United States, the efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER) which is defined by the Air Conditioning, Heating, and Refrigeration Institute, a trade association, in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment.

The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP is used in thermodynamics.
Saudi Arabia's Köppen climate classification map.. The climate of Saudi Arabia is marked by high temperatures during the day and low temperatures at night. The country follows the pattern of the desert climate, with the exception of the southwest, which features a subtropical highland climate and a semi-desert climate.
Autumn, in some ways, is a calmer season than any of the other three in Chicago. However, wild weather can and does occur in the region during this season. In most years, a period of warm weather, known as an Indian summer, occurs well after the autumnal equinox has occurred. In these so-called Indian summers, unusually warm weather can persist ...
Its poleward progression is accelerated by the onset of the summer monsoon which is characterized by the development of lower air pressure (a thermal low) over the warmest part of Asia.Mawsynram in Meghalaya received annually 11872 cm of rainfall [4] [5] [6] Cherrapunji. The highest recorded rainfall in a single year was 22,987 mm (904.9 in) in ...
