Upgrading air conditioning systems in the past used to require replacement of refrigerant piping in buildings, leading to major construction and costs exceeding those of the original installation.
To save time and cost, Daikin developed the VRV IV Q Series as a model specializing in system replacement. This revolutionary system reuses existing piping and enables quick and high quality replacement to the latest energy-saving air conditioning system without renovation work for new piping.

Time saving
Enables smooth replacement of air conditioning with less effect on operation and user in the building.
Cost Saving
Work costs for pipe removal, installation and insulation account for almost 80% of the total cost. By the reuse of existing piping, 45% of cost down can be realized compared to installing new pipes. On top of the benefits from reusing pipes, costs of charging refrigerant to clean the pipes are also saved.
Space saving
As a leading global innovator, Daikin advanced from the conventional 2 module combination to a single module for 18 and 20 HP models. This allows the installation area to reduce by 33% as compared to the previous models.
Swing compressor
Daikin swing compressor has integrated the rotor with the blade, completely solving the refrigerant leakage and the wear problem caused by the mechanical friction between the rotor and the blade, which enhances the compressor efficiency and makes the compressor more quiet and durable.
New technology that enables use of existing piping
A new method collects contamination from existing piping, eliminating compressors and electric valves malfunction
