Information

Hypothesis and equations

Simple model of a heating and cooling system with fixed or prescribed temperature setpoints.

Bibliography

none

Instructions for use

The temperature setpoints for heating and cooling can be defined either :

• as fixed parameters if use_T_input=false (by default) : respectively T_heat_sp and T_cool_sp
• as RealInput if use_T_input=true : the connectors T_heat_input and T_cool_input shall be connected to blocks that generate the signal for respectively heating and cooling temperature setpoint

These temperature setpoints are stated in °C.

Known limits / Use precautions

Of course, this model should not be used if T_heat_sp > T_cool_sp or T_heat_sp_input > T_cool_sp_input.

Safeguards should be added to prevent bug.

Revisions

Mathias Bouquerel 05/2017 :

• The RealInput and parameters for temperature setpoints are renammed as T_heat_XX and T_cool_XX for which are easier to understand.
• The boolean use_power_integrators can be used to add or not integrators on the heating and cooling power signals.
