Air conditioning method

A climate control method as a follow-up control system, in which system an internal area temperature is controlled taking into account an external temperature, by determining and adjusting a blowing-in temperature of the flowing in a medium flowing from an exterior to an interior, to a nominal internal area temperature which is stored and is set by an occupant, with the medium first of all being cooled down and/or heated before flowing in, as a function of the external temperature, the method comprising the steps:

• storing the nominal internal area temperature value in a first memory,
• (S1) detecting the external temperature an actual internal area temperature and of the nominal internal area temperature setting, and calculating a first nominal blowing-in temperature as a function of the external temperature, of the actual internal area temperature and of the nominal internal area temperature setting,
• (S2) comparing the calculated first nominal blowing-in temperature with a predetermined minimum blowing-in temperature, which is above an icing-up temperature of an air-conditioning system,
• (S3) if the first nominal blowing-in temperature is above the predetermined minimum blowing-in temperature, carrying out climate control as
• a function of the actual internal area temperature, the nominal internal area temperature, the external temperature by controlling the blowing-in temperature,
• (S4) if the first nominal blowing-in temperature is below the minimum blowing-in temperature, determining whether the stored nominal internal area temperature setting and the stored nominal internal area temperature value in the first memory are the same, whereas if the setting is the same as the value, return to S1,
• (S5) if the setting is different from the value, determining a nominal internal temperature change from the difference between the stored nominal internal area temperature setting and the stored nominal internal area temperature value in the first memory,
• (S6) if the nominal internal area temperature change has a value less than or equal to zero, returning to S1, TP (S7) if the nominal internal area temperature change has a value greater than zero, calculating a second nominal internal area temperature as a function of the nominal internal area temperature change and of the external temperature in such a way that this results in an increase in the nominal blowing-in temperature,
• (S8) comparing the first nominal blowing-in temperature and the second nominal blowing-in temperature, and selecting the larger of the first nominal blowing-in temperature and the second nominal blowing-in temperature,
• (S9) if the second nominal blowing-in temperature, is not selected, return to S1,
• (S10), if the second nominal blowing-in temperature is selected, closing an outlet valve for a predetermined time period, and then return to S1.
