Improved model of the constant air flow air-conditioning system

The EnergyPlus calculation model used to simulate the air conditioning unit of the constant air flow system has been changed. Previous versions used a "template" type model available in the calculation engine, which presented configuration and combination restrictions with other systems in the same job. The change of model in version 2024.a eliminates these restrictions. Furthermore, the system definition interface has been divided into tabs to make it clearer.
