Information
This model represents a conventional vehicle thermostat with first order delay. Using the input signal temperature the open state of the thermostat is defined. The thermostat temperatures Toff and Ton can be used to parameterize the open state. At temperature Ton the thermostat is completely open and at Toff the thermostat is completely closed. The temperature Ton must be higher then the temperature Toff. The pressure loss characteristic of the thermostat is modeled in the SmartCooling.Components.IsolatedValve. The parameter timeConstant is the first order delay time constant.
