• This has a dramatic impact on Power Consumption and helps improves energy efficiency.
• The VRV IV-W Series allows for extensive refrigerant piping, enabling several spaces to be cooled by a single refrigerant circuit. 
• The VRV IV-W Series uses the same Daikin inverter technology that is used with air-cooled systems, but extends the application of VRV products by utilizing the same quality family of VRV indoor units and controls options.

Water-Side Infrastructure and Components:

• A water loop system is routed around the building, either vertically or horizontally. 
• This can be either plastic or steel pipe work.
• Heat Injection (Boilers) and Rejection (Cooling Tower or Dry Coolers) are required to ensure that the water loop stays between the required design conditions of 67 and 95 Degree F.

The reason split type air conditioners are so termed is that they divide the elements of a conventional air conditioning system into two separate units, one interior and one outside.Copper tubing is used to connect these two units in place of central air systems' pricey ductwork. This copper tubing is flexible, allowing homeowners to quickly build a split type system without considerable construction. The capacity to manage several indoor fans from one outside unit, much like a central air system, is also made possible via these connections.
