Air conditioner, especially for a motor vehicle

摘要

The installation includes a variable-pressure compressor (5) in a coolant circuit, an adjustable flap (13) for varying the proportion of fresh air to recirculated air, and two sensors (20,21) measuring the interior and exterior temperatures. A desired temperature can be set (19) by a passenger. A processor (18) calculates the difference between desired and actual interior temperatures, compares this with a memorised threshold, and then compares the interior and exterior temperatures. A controller (16) operates the flap on the basis of the results of these comparisons.
