Hitachi VRF System

VRF stands for Variable Refrigerant Flow, and it's an advanced technology that uses refrigerant to cool or heat the indoor environment. In simple terms, a VRF system is a multi-zone air conditioning system that allows you to control the temperature of each individual zone, room, or floor.Based on the ambient temperature in a room or space, algorithms determine the optimal amount of refrigerant that needs to be sent from one or more ODUs to each individual IDU to achieve the required temperature at any given moment. For this reason, VRF systems are normally more energy efficient than installing multiple 'single split' systems (consisting of multiple pairs of ODUs and IDUs which operate independently of each other) especially in 'part load' conditions, where the system does not need to work at full capacity. Each IDU can be controlled by both a remote or individual room controller and a centralized controller (covering many rooms or zones), which makes monitoring easier and efficient in terms of total energy optimization operation.They are particularly suitable for multi-room or multi-zone spaces which may have different levels of exposure to sunlight (and therefore different ambient temperatures) in the same building, therefore individual comfort (temperature/mode) is appreciated
