What is VRV?Daikin VRV system is a multi-split type air conditioner for commercial buildings that uses variable refrigerant flow control developed by Daikin.

It enables long piping length up to 165m and maximum level difference (between outdoor and indoor units) of 90m to provide more design flexibility which can match even large-sized buildings.

It allows one touch selection control using intelligent Touch Manager and includes options to link with BACnet® to enhance the Building Management System (BMS).

Daikin release a new standard series unit model AHUR-CA/SA (Single Skin / Double Skin). It is a DX AHU system that is specially designed to work with the VRV IV outdoor unit. This new model release is an inlet temperature control type AHU. This will enable the users to reduce maintenance costs and enjoy more space savings.

AHUR-CA/SA also improves the indoor air quality from haze, pollutants, etc using the options of pre-filers and primary filters. VRV+AHU are the only total AHU solutions provided and manufactured completely by Daikin.

VRV+AHU ApplicationFor small to large commercial spaces Daikin offers a range of R-410A inverter condensing units for use in conjunction with Air Handling Units (AHU) from 6 HP to 60 HP.

AHU provide large volumes and high ESPs (External Static Pressure) enabling the use of extensive ductwork runs. The refrigerant flows through the copper pipes using R-410A and operates like a large VRV fan coil unit.

Daikin AHU represents the ideal solution for large storage places, atrium, lobby, banquet halls, showrooms, exhibition halls, shopping malls, etc.

It also have the options to customize the specifications such as the filtration type, direction of air in-take and discharge, service access door and blower type (backward or forward curves and plug fan).?

Features of VRV+AHU - Inlet Temperature control

• Harnessing VRV IV current and latest

technology of VRT

• Inverter controlled system (only Z - Control)

• Can be easily controlled via standard wired remote

control (BRC1E62)

• Comes in dual skin type model - double skin panel

model and single skin panel model

• Easily manage using intelligent Touch Manager

central control system

Communication protocol using DIII-Net to

communicate with all existing Dakin

communication devices and even BMS.

• Can be placed indoor or outdoor*

*Optional items required

Benefits of using VRV+AHU

• Quality assured

VRV+AHU are manufactured by Daikin factory.

• Ease of the installation

No additional system such as cooling tower, chiller,

and long water piping system are required. This

also reduces the total system maintance costs.

Flexible design of the ducting system.

• Cover large area with different ducting configuration.

• VRV+AHU can provide ESP up to 500Pa*

(Standard Model)

• Total solution concept

Integrating an AHU into the total building climate

system enables both design and installation

procedures to be based on a single common

technology. This simplifies project follow-up,

installation, commissioning and maintenance

since only one party is involved.

• VRV+AHU system can be coupled and mixed with

other type indoor unit to work together concurrently.

(Connection ratio 50% - 110%)

The VRV+AHU standard series are available from the capacity range of 6HP to 60HP, also with airflow ranging from 3,240 CMH – 28,080 CMH.

Airflow (x 103 CMH)

VRV+AHU Standard Series Coil, Expansion Valve Kit and Control BoxAHUR-CA/SA standard series model is using the DX coil. Each DX coil will be connected to one external expansion valve kit (EKEXV) and controlled by one control box kit (EKEQMCB).

VRV+AHU Standard Series Coil

• 3 Type of Coils - 6HP used by 6HP, 12HP AHU unit - 8HP used by 8HP, 16HP AHU unit - 10HP used by 10HP, 20HP, 30HP, 40HP, 50HP, 60HP AHU unit

VRV+AHU Expansion Valve Kit (EKEXV)

• 3 Type AHU Expansion Valve Kit - EKEXV140 for 6HP Coil - EKEXV200 for 8HP Coil - EKEXV250 for 10HP Coil

VRV+AHU Control Box Kit (EKEQMCB)

Possibility Z (Ts/Tr control):Using Daikin wired remote controller (BRC1E62 - optional) Set point can be fixed via standard Daikin wired remote controller. Remote ON/OFF can be achieved by an optional adapter KRP4AA51.

No additional external controller is required. The cooling load is determined from the air suction temperature and set point on the Daikin controller.
