Abstract:

Air Conditioning System is the process of treating the air to simultaneously control temperature, humidity, cleanliness & distribution to meet the requirements of a room, such not only at office buildings, malls, airports but also at residences. Indonesia, with its tropical climate, which has hot, dirty (dusty, smoky) air and erratic winds, needs a way to get comfortable using air conditioning equipment. In this paper, the calculations were carried out, taking into account the ASHRAE standards. For Space references and calculations, the plan is developed by AUTO CAD. Along with the development of Air Conditioning technology and the increasing awareness of climate change, energy consumption, and also more flexible layout of Air Conditioning placement so as to get comfortable, making the use of VRV - A continues to grow not only in office buildings but also in residential areas. This paper will explain how to design an Air Conditioning system of VRV-A by selected indoor unit and an outdoor unit with connection ratios between 50% - 200%. The cooling load calculation is carried out by using HKGSG v 2.05 software and HAP software v 4.90, which is available in the worldwide market. Nowadays, people are estimating the cooling load calculation by approximation method, i.e., by giving dimensions of the building, which the sellers are estimating roughly the cooling capacity.
