Finned-Tube Evaporator Model With a Visual Interface

Published

Piotr A. Domanski

Abstract

This paper presents a finned-tube evaporator model and its utility when equipped with a window-based interface. The modeling scheme is tube-by-tube and allows for specification of complex refrigerant circuits, modeling refrigerant distribution between these circuits, and acounting for non-uniform air distribution. Evaporator capacity is obtained based on the simulated performance of each tube in the evaporator assembly using inlet parameters and mass flow rates of the refrigerant and air associated with a given tube. Simulation results also include local parameters for each tube such as inlet and outlet quality, temperature, enthalpy, entropy, pressure drop, mass flow rate for refrigerant and inlet and outlet temperature for air. The local data are displayed for each tube on a side view of the heat exchanger identifying tube connections, which facilitates a detailed understanding of the optimized evaporator's design.
