APPLICATION OF TECHNO-ECONOMICS IN THE DESIGN OF COOLING MACHINE DUCT FOR LABOR SCALE MECHANICAL ENGINEERING MUHAMMADIYAH UNIVERSITY OF WEST SUMATERA

Abstract

The cooling machine duct is an air duct used to deliver cold air to the room. This cooling machine channel is used to observe changes in temperature, humidity, enthalpy and air flow rate against heat transfer. This study focuses on the design and manufacture of laboratory-scale cooling machine channels by applying techno-economics. The results show that this cooling machine channel test tool is suitable for use in mechanical engineering laboratory experiments with lower operational costs and meets laboratory needs.
