Calculation of VRV and SPLIT Type Air Conditioning Systems Through the New Desing Tool Computer Program

The article is devoted to the calculation of VRV and SPLIT type air conditioning systems through the New Desing Tool computer program. The program processes data on external and internal air parameters, loads on the air-conditioned room and calculates the total heat and moisture balance, selects the main nodes of the system according to the loads, establishes the principle, installation, electrical diagrams, and transfers the drawings to the AutoCad program. The program has protective mechanisms, in particular, if in any node parameters are obtained that deviate significantly from the nominal value, the program is blocked and does not allow to move forward, therefore it is necessary to eliminate the error made immediately.
