6.2.9. Control Model

The control model used for system simulations in EINSTEIN can be defined via the tree item -> “Control Model”.

The operation of heat and cooling supply equipment is supposed to be driven by demand, this is the demand of the distribution pipes or ducts connected to each equipment. The order of the equipment entering depending on the level of heat and cooling demand is defined by the heat and cooling supply cascade (see the Technical Manual for further details).

The supply cascade can be changed moving equipment up and down.

• the equipment on top of the cascade will enter first in order to cover base load
• the equipment on the bottom of the cascade will enter last providing peak load if necessary

In addition, for each of the equipment an individual master control schedule can be defined (plus-version only).
