Abstract
In hot & dry climate conditions, air conditioning plays important role to achieve thermal comfort. Malaysia shows a significant increase in demand of split unit installation in this past 3 years. However, the installation of split unit typically is using manpower and manual lifting process. Therefore, the ergonomics emphasized to the blue-collar worker will have significant impact to their health. Besides, ergonomic and safety are related with each other to keep society safe. This study aims to develop a low-cost portable lifter to lift split unit air conditioning system. Earlier study stated that 90% of 112 houses install Room Air-Conditioning in home. Installing air-conditioning outdoor unit led into several problems which is not ergonomic and less safety factor. From 2014 until 2016, the number of demands for window-type air conditioning in Malaysia are very low which is only 14 rather than split-type which has demand in about 2429. Before the designing process, 30 sets of questionnaires have been distributed to see what the criteria that will ease the installer or worker task. It also been done to develop house of quality based on the survey. Then, SolidWorks software has been used in designing portable outdoor unit lifter. After the designing process finished, the fabrication process has been done. This portable outdoor unit lifter could lift outdoor unit until 8feets. The used of hand-winch gear ratio was 3.4 in this product. In addition, the appropriate gear ratio was 5.33 for 2HP outdoor unit which weight around 40kg. Other than determining the appropriate gear ratio, the force needed to lift the outdoor unit are also been determined. Thus, this product also can handle up to 70kg of outdoor unit. Henc
