•The aptitude to keep a definite temperature in a building when the temperature is lower depends on the amount of heat and the total heat losses.

• More heat is to be added than to be lost via radiation, convection and conduction.

• This amount of heat does depend on the heat of the building ma­terials, the contents of the building, and the temperature increase.

•The heating system should have a reserve capacity adequate to bring the temperature up to the desired point in a reasonable duration of time.

• That schools or industrial buildings can be kept at lower tempera­tures during the night or period when unoccupied — is evident.

•Since the heating capacity depends on the heat losses, the first step in laying out a system is to determine possible losses.

•The main losses are due to the heat transmission through the out­er walls plus convection losses because of wind conditions and build­ing exposure.

•The prevailing winter wind is proved to add at least 15% of the total heat losses on the exposed sides.

•Structural design, style, and thermal insulation are to be compati­ble with local climatic and weather conditions, especially severe ones.

TEXT F

Keeping cool has been a human concern for millennia... The idea of air conditioning had started before a machine was made to produce the cooling effect. First attempts were made by a physician John Gorrie (1803-1855) in Florida. Dr. Gorrie was the very man to create an ice-making machine blowing air over a bucket of ice for cooling hospital rooms of patients suffering from malaria and yel­low fever.

A close 'ancestor' to modern air conditioners was made in 1902 by an American engineer Willis Carrier. The machine called 'Apparatus for Treating Air' was built in New York. After that breakthrough, air conditioners began to bloom though they were large, awkward, expen- sive, and dangerous due to the toxic ammonia used as a coolant.

After World War II, first window unit air conditioners appeared. Today it is an invention that is almost impossible to live without.
