Technology Description
As a leading global innovator, Daikin advanced from the conventional 2 module combination to a single module for 20 HP model. This allows the installation area to reduce by 43% as compared to the previous VIII Series.
Estimated Life Time
15 years
Estimated Lead Time
3 month
Technology Features
  1. Increase surface area of heat exchanger for better performance
  2. Easy maintenance
  3. Sufficient cooling for electrical component
  4. Eliminate suction resistance issue to enhance air flow volume.
Technology Advantages
The new VRV IV system now features VRT technology. VRT automatically adjusts refrigerant temperature to individual building and climate requirement, thus further improving annual energy efficiency and maintaining comfort. With this excellent technology, running costs are reduced.
Technology Limitation
Cost and Benefit Analysis
During cooling, the refrigerant evaporating temperature (Te) is raised to minimise the difference with the condensing temperature. Compressors work less, and this reduces power consumption.
