Analysis of the operational characteristics of multi system through steady-state and dynamic simulation.

Author(s) : LEE G., LEE I. H., YOO K. J., et al.

Summary

Steady-state simulation and dynamic simulation were performed to analyze the effect of operation conditions of each indoor unit of a multi-type air conditioning system. Lumped parameter model and fully distributed model were applied to simulate the steady state and transient responses of the system considering the dynamic natures of each component. Since the main purpose is to analyze the effect of one indoor unit on the other unit, numerical simulations were carried out for the variations of secondary fluid inlet temperature, mass flow rate and expansion valve opening. The results showed that the inlet temperature and mass flow rate of the secondary fluid of one indoor unit had minor effect on the operation of the other unit. However, the opening of the expansion valve had significant effect on the performance of the other unit.
