Abstract

Wall-mounted split air conditioners are the most widely used heat pump air conditioner type in Turkey. They are used extensively in living and working environments for cooling in the summer and heating in the winter. This widespread use has significantly increased the need for trained, informed, and analytically minded technical personnel capable of pinpointing, fault diagnosis, and properly servicing devices. This training set, produced for educational purposes, aims to comprehensively teach the operating principles, service procedures, electrical fault detection, temperature and pressure changes, and fault diagnosis methods of wall-mounted split air conditioners. All manufacturing processes are detailed, and circuit diagrams are drawn, explaining the operating principle of the set in a manner suitable for use in vocational and technical schools. This study examines the electrical fault detection, service procedures, and changes in the device resulting from artificial faults in wall-mounted split air conditioners using the developed training set. The causes of these faults and their possible solutions are explained.
