The air-conditioning unit has a variable compressor (1) driven from the automobile engine (4), an evaporator (9) for cooling the air and a control unit (5), supplying a control current for the compressor in dependence on the difference between the actual and required temperatures of the ...
1911:Carrier presented his Rational Psychometric Formulae, which is the fundamental science used behind air conditioning technology today. 1914: The first in-home air conditioning machine (made by Carrier) is installed in a Minneapolis mansion. It was seven feet high and 20 feet wide. Up to thi...
In an air-conditioning system for a motor vehicle, having a coolant circuit formed from a compressor for compressing the coolant, a condenser for cooling the compressed coolant, an
