    This subsystem takes care that the cabin temperature is kept between specified borders and if the temperature in the cabin is reached, then the entire AC circuit is turned off. Additionally the inertia of evaporator is taken also into account.

    This simulation features a control system in which is the cabin temperature kept in specific borders by turning on and turning off the entire AC systems.

    When the AC system compressor is turned off and the air still flows through an evaporator the inertia of the evaporator causes the air to cool itself by rejecting heat and at the same time warming the evaporator until it reaches the ambient temperature. In order to take this phenomenon into account, this system was created.

    Also in this case is the transient behavior of an evaporator simulated by a point masses. In order to reach a smoother outlet temperature curve a heat conduction coefficient is positioned between the evaporator air side point mass and the evaporator refrigerant side point mass.

    Usable from release: KULI 9.1-0.01
    Necessary modules: KULI base + KULI hvac
