Daikin VRV T-Series
Water Cooled Systems
What is Daikin VRV T-Series?
One Flexible Package
Daikin VRV is a modular, commercially applied air-conditioning and heating system that distributes refrigerant from the outdoor unit to multiple indoor units, providing efficiency, comfortable individual user control and reliability in one flexible package.
The VRV Water Cooled system combines the characteristics of a water cooled system with the air cooled VRV system and still use the same VRV indoor units, similar refrigerant piping methods, branch selector boxes, and controls as air cooled VRV systems. The main difference is that heat is rejected or absorbed via the condensing units to and from the water loop instead of the outside air.
The VRV Water Cooled T-Series offers an energy saving alternative to traditional centralized equipment. The system design is based on a modular design concept. It is composed of unified condensing units that require simply connecting a 2-pipe refrigerant network for heat pump applications or a 3-pipe refrigerant network for heat recovery applications. The condensing units are conveniently compact, which not only enables transport by elevator possible, but also effectively simplifies installation in mechanical rooms. This also saves a great deal of time and labor.
VRV Water Cooled systems are equivalent to 2-pipe or 4-Pipe chilled water systems, but also offer a viable alternative to Water-Source Heat Pump solutions. Each connected Indoor Unit can provide heating and cooling independently to suit zone requirements making these systems suitable for both open plan, or cellular applications with different operation requirements.
The VRV water cooled system can connect to a geothermal water loop as standard, which makes it one of the most energy-efficient air-conditioning systems available in the market.
Underground temperatures remain relatively constant all year round. They are warmer than the air above it during the winter and cooler than the air above it during the summer.VRV Water Cooled systems are capable of utilizing this constant temperature by exchanging heat with the earth through a ground heat exchanger.
This helps reduce the load on the compressor and provides substantial energy savings.
Why select a VRV Water Cooled System?
- The efficiency and capacity of air-cooled systems reduce at extreme ambient conditions, causing systems to be oversized and increasing initial cost. Water cooled VRV operation does not get affected by outside air temperatures.
- Geothermal energy can be used to heat and cool your building, which can help you gain more LEED points.
- Extreme piping lengths in applications such as high-rise buildings cause capacity reductions. Positioning water cooled condensing units floor-by-floor reduces the capacity reduction and improves the system efficiency.
- Water cooled VRV systems typically require less base refrigerant charge than that of a similar air cooled VRV system and thus can be used in applications with limited allowable refrigerant within the building.
- Condensing units can be linked to existing water piping and utilize the existing heat source to reduce initial costs.
- No external operation sound produced by condensing units to disturb your building neighbors since water cooled VRV systems are installed indoors only.
Designed for absolute comfort and versatility, Daikin's wide selection of ducted and duct-free indoor units with a sleek and sophisticated design provides zoning flexibility and comfort control for almost any application.

Features and Benefits
Geothermal Operation and Advantages
VRV T-Series can use the Earth as a Heat Sink, eliminating the need for another heat source. It uses the clean and sustainable energy stored in the earth to heat and cool buildings, which makes the VRV a more environmentally friendly solution.
Indoor installation makes unit invisible from the outside
Because the system is water cooled, outside air temperature does not affect system capacity. Condensing units are installed inside the building, which enhances design flexibility and makes it easier to adapt to different buildings types.
›› Great solution for sound sensitive environments as there is no noise mitigation outside to disturb building neighbors
›› Superior efficiency, even in the most extreme outside conditions, especially in geothermal operation
Extended Water Temperature Operation Range
Condenser water inlet temperature can be as low as 23°F in cooling and 14°F heating. Please note that glycol usage is required when EWT is below 50°F. Please refer to Engineering Manual for further details.
2-Stage Heat (Energy) Recovery
2-Stage Heat (Energy) Recovery is available between indoor units on the same VRV system and then across all the systems connected to a common water loop. This has a dramatic impact on power consumption and helps improve energy efficiency.
Variable Water Flow Control
Condensing unit can control water control device such as an inverter pump or modulating valve via 0-10V signal based on capacity requirement. This increases the total system efficiency by reducing the water flow when possible.
Space Saving – Compact Design & Stacked Configurations
Compact casing (Height: 38-9/16” Width: 30-1/8” Depth: 22-1/16”) allows for stacking of the units to maximize space saving. Stacked systems can easily fit in mechanical rooms with 7 ft. (dual stack) or 11 ft. (triple stack) ceilings thanks to the
reduced unit height.
Heat Rejection Cancellation Technology
Engineered with Patented heat rejection cancellation technology to eliminate heataddition to mechanical rooms*
* This function needs to be enabled through field settings.
Easy Installation and Servicing
Developed for easy installation and servicing: options to choose between top or front connection for refrigerant piping and drop-down switch box for easy access to components.

Simplified Commissioning and Servicing
- New configurator software designed to simplify the commissioning and maintenance of the system.
- 3-digit 7-segment digital display on the unit for improved and faster configuration, commissioning, and troubleshooting.
