What is a VRF system?
VRF (Variable Refrigerant Flow) is a "direct expansion" air conditioning system, meaning that air is cooled directly by the refrigerant in or close to the area being conditioned. VRF differs from most other types of "direct expansion" systems because it can send different amounts of refrigerant to various indoor units located throughout a building - in doing so it is possible to manage different temperatures simultaneously in different parts of a building. A VRF system consists of one or more Outdoor Units (ODUs) and multiple Indoor Units (IDUs).
How does VRF system work?
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.
Where are VRF systems used?
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
