Development and application of variable frequency pump module based on TRNSYS

In the application of TRNSYS simulation software to simulate fixed temperature difference frequency control for air conditioning system, the variable frequency pump module type748 provided by TRNSYS software is very inconvenient in application. Therefore, according to the theoretical research on the operating point and operating power of the variable frequency pump, establishes a mathematical model for fixed temperature difference frequency control, and develops a new variable frequency pump module type217 based on TRNSYS software. Builds a TRNSYS simulation platform of fixed temperature difference frequency control for air conditioning system with type217, and the simulation results show that the variable frequency pump module has high reliability and can be applied to simulate the fixed temperature difference control of air conditioning water system.
