Variable refrigerant flow (VRF) is an air-condition system configuration where there is one outdoor condensing unit and multiple indoor units. The term variable refrigerant flow refers to the ability of the system to control the amount of refrigerant flowing to the multiple evaporators (indoor units), enabling the use of many evaporators of differing capacities and configurations connected to a single condensing unit. The arrangement provides an individualized comfort control, and simultaneous heating and cooling in different zones. Currently widely applied in large buildings especially in global. Many countries have test procedures, standards, and labeling (mandatory and/or voluntary) schemes for a wide variety of products. In the majority of cases, these test procedures and resulting performance levels are different, resulting in a worldwide patchwork of testing and performance requirements for manufacturers to meet in order to sell in that market. Test procedures and rules may be published as formal standards by an economy’s standards-setting agency or by an international agency such as the International Standards Organization (ISO) or International Electrotechnical Commission (IEC) or both. Even some products have International test procedures, but it is not fully comparative to test energy consumption or energy efficiency. Recently regional, and national standards for VRF system were developed in Europe, US, and Japan. In 2006 KS of multi-split air-conditioner had been developed fully comparative with ISO. But there is no part load conditions, which is not fully acceptable to all stakeholder. Therefore Korea government developed a new test method based in AHRI for energy efficiency label and standard program. But, there are some unique differences to evaluate performance with other standards. In this study comparisons of existing regional standards was introduced, discussions to improve the performance rating of VRF system were presented.
