The combination of heat transfer between solid (ice) and fluid with cosentrasion ice can increases performance of heat exchanger. At this research will investigate adding of ice in fluid freezer to heat transfer parameter in compact exchanger. From the result of research show that heat transfer with phase change at cold fluid can increase heat transfer from hot fluid.. This Phenomena is caused that laten heat of ice made a little change of the temperatur fluid freezer as long as the time, therefore rate of heat transfer side hot fluid increases too. So the difference of temperatur between side cold fluid and hot fluid made become higher. From analysis doing for some mass flow rate of fluid frezeer, the difference of ice slurry with cold water in temperatur Oc is about 15-30 % of energy which can be given by ice. And heat transfer increases 45-72 % if it compared with water which has temperatur near by the outlet temperatur of chiller system, The researct is also done in a theoritical calculation by mathematic modeling and numerical method, which can be repeated for different input data quickly. And program designed is good enough to be used in analyzing a compact heat exchanger.
