These two subsystems can be used to calculate the amount of heat exchanged by a heat exchanger. For HVAC components (evaporator), the subsystem “EVP heat calculation” computes the amount of latent and sensible heat. For all other heat exchangers, the subsystem “Heat calculation” can be used.
Due to their modeling as a subsystem, both models could easily be used in the users KULI simulation.
Both subsystems can be included in any existing KULI file. To insert it, use the subsystem import function. It might be possible that the signal receivers included in the subsystem must be adapted. Therefore double-click the signal receiver symbol and change the linked component.
Once successfully included, the system calculates the latent and sensible heat (subsystem “EVP heat calculation”). In case of not using it in an HVAC system, subsystem “Heat calculation” can be used to calculate the sensitive heat (which is also directly available by the component).
The calculation of the heat is done by several calculation controllers, the material properties (for the cp value) are computed by the Medium controller. To get the input values for the calculation controllers (mass flow, in- and outlet pressure / temperature), signal receivers are used.Usable from release: KULI 9.1-0.01
