Abstract
The object of this invention a regulation method for regulating an air conditioning system suitable for independently regulating the temperature of a plurality of zones. The air conditioning system comprises a thermal cycle machine. According to various embodiments, the thermal cycle machine is capable of delivering a cold airflow, a hot airflow or both. This flow is divided into smaller flows supplied to each of the zones to be regulated. The method according to the invention allows regulating these smaller flows as well as the operating conditions of the thermal cycle machine. According to various embodiments, the method additionally incorporates more complex variants involving variables such as pressure or thermal inertia. Likewise, according to one embodiment the air conditioning system incorporates a particular distributor configuration simplifying the installation of said regulation system.
