A Model of an Air-Conditioning Condenser and Evaporator with Emphasis on In-Tube Enhancement

A MODEL OF AN AIR-CONDITIONING CONDENSER AND EVAPORATOR WITH EMPHASIS ON IN-TUBE ENHANCEMENT Kuo-Hsiu Huang Michael B. Pate Mechanical Engineering Department Iowa state University Ames, Iowa 50011 A computational model for air-conditioning condensers and evaporators with in-tube enhancement has been developed. The purpose of this model is to provide a tool for the design of plate tinned-tube he...

Analysis of Exergy Destruction of an Evaporator or/and a Condenser

Preliminary note This paper presents the exergy destruction of an evaporator or a condenser or evaporator and condenser. The exergy destruction can be analytically calculated by using the same non-dimensional variables which have been used by its energy analysis. The one additional variable is the ratio of absolute input temperatures of both streams. This means that the given model enables the ...

Evaluation of Evaporative Cooling for Heat Transfer in the Condenser of Window-Air Conditioners

There is a demand for reduced power consumption in the vapor compression refrigeration cycle. Coefficient of performance of window-air conditioners considerably decreases and power consumption increases under very hot conditions. These problems have encouragecl studies aimed at improving the performance of window-air-conditioners by enhancing the heat transfer rate in the condenser. In this ar...

Genetic optimization of heat transfer correlations for evaporator tube flows

Two-phase heat transfer coefficients for internal flows play a critical role in the design and analysis of evaporators and condensers. Previous studies propose empirical relations that combine the effects of nucleate and convective boiling onto the overall heat transfer coefficient. Although these relatively simple empirical relations offer physical insight on the nucleation, boiling and flow p...
