It is a DX AHU that is specially designed to operate with VRV outdoor unit. This enabled the users to reduce maintenance costs and enjoy more space savings. Daikin VRV AHU improves the indoor air quality caused by haze, pollutants, etc with options of pre-filers and primary filters. This is the only total AHU solutions provided and manufactured completely by Daikin. Total Daikin Solutions (All products manufactured by Daikin Factory) Air Handling Unit Control Wiring Remote Control Wiring (P1P2) Liquid Gas VRV AHU System Schematic VRV AHU Application From small to large commercial spaces, Daikin offers a wide range of R-410A inverter condensing units for use in conjunction with Air Handling Units (AHU) from 6 HP to 120 HP. Daikin AHU represents the ideal solution for large storage places, atrium, lobby, banquet halls, showrooms, exhibition halls, shopping malls, etc. AHU provides large air volumes and high ESP (External Static Pressure) enabling the use of extensive ductworks. The refrigerant flows through the copper pipes using R-410A and operates like a large VRV fan coil unit. It also has 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). What is VRV? Daikin VRV system is a multi-split type air conditioner for commercial buildings that uses variable refrigerant flow control invented 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). 03 Nomenclature AHURS 06 DB V AHURS 06 DB V DX Air Handling Unit Horizontal Mount Cooling Capacity: 06 = 6HP Double skin 50mm thickness V: Standard | L: Outdoor Air VRV AHU Comparison Table and Diagram for Conventional AHU System and VRV AHU System Conventional AHU System VRV AHU System Require Frequent Maintenance (Cooling Tower + Chiller) Easy Maintenance (same as common A/C System) Higher Cost Due to Frequent Maintenance No Additional Maintenance Cost Require Larger Installation Space (AHU, Chiller, Coolong Tower) Require Small Installation Space (AHU, VRV) Complex System (HVAC Ducting, Chiller and Water Piping) Simple System (HVAC Ducting) Complex Control (Variable Frequency Device, Variable Air Volume Control) Cooling Tower Simple Control (Remote Control / Intelligent Touch Manager / MicroTech III Controller) Free space Office Office AHU Office Lobby Chiller Basement Carpark Conventional AHU System Office VRV IV Max. 90m Office AHU Office Lobby Basement Carpark VRV AHU System 04 Standard Series AHURS-DBV VRV AHU Introduction Standard Series The VRV AHU standard series are available from the capacity range of 6 HP to 120 HP, also with airflow ranging from 3,240 CMH - 59,760 CMH.

VRV AHU Outdoor Air Series Evaporator Coil, Expansion Valve and Outdoor Air Series PCB AHURS-DBL Outdoor air series use DX coil. Each DX coil will be connected to expansion valve and controlled by one Outdoor air series PCB.

The MT III controller translates the temperature difference between set point and air suction temperature (or air discharge temperature or room temperature) into a reference voltage (0-10V) which is transferred to the Daikin Outdoor air series PCB. This Reference voltage will be used as the main input value for the compressor frequency control. MT III AHU Daikin Outdoor air series PCB Room Td = Air discharge temperature Temperature (13°C ~ 28°C) Te = Evaporating AHU = Air Handling Unit MicroTech III controller (option) MT III controller is recommended for Outdoor air series AHU controlling, switching and monitoring functions. This controller is programmed to optimize the performance and efficiency of VRV AHU automatically. It can also communicate with Daikin's intelligent Touch Manager via BACnet protocol easily. 12 Outdoor Air Series AHURS-DBL VRV AHU Configuration MT III Controller (option) Control Wiring MT III Control Wiring Liquid Gas Combined VRV System Configuration VRV 20 HP VRV 20 HP VRV 20 HP Control Wiring Remote Control Wiring (P1P2) Liquid Gas Multiple VRV System Configuration 13 Outdoor Air Series AHURS-DBL VRV AHU Configuration 1 CASING / INSULATION (DBL SERIES) 50mm Thickness Double Skin Polyurethane Insulated Sandwich Panel 0.5mm thick Pre-Painted (white) Galvanised Steel Thermal Break System, Ozone friendly Polyurethane Foam 45±2kg/m3 WEATHER PROOF ROOF SUS 304 2 CASING-FRAME (DBL SERIES) Extruded Aluminium Profile COIL DX Coil TUBE Copper Tube 3 FIN HEADER Aluminium Fin, 0.2mm, Corrugated Fin Pattern c/w Ripple Edge Copper Tube-Connect FRAME Galvanised Steel WORKING PRESSURE 10Kg/cm² FAN (Brand = Kruger) TYPE Double Width Double Inlet Forward Curved Cetrifugal Belt Drive Fan 4 WHEEL Galvanised Steel Sheet HOUSING Galvanised Steel Sheet FRAME Steel With Polyester Powder Coating 5 MOTOR 6 VIBRATION ISOLATOR (Brand = Elektrim) Three-Phase Induction Motor Totally Enclosed Fan-Cooled Type Protection = IP55 Insulation Class = F Efficiency class IE3 Spring Isolator 7 DRAIN PAIN (DBL SERIES) 1.2mm (SUS 304) The Drain Pan is Covered with PU Insulation 40Kg/m³ Density 8 AIR FILTER (Brand = AAF) Type = R29 Class = G3 (AFI = 80-85%) Synthetic Washable Size = Full (24" x 24" x 2") Half (12" x 24" x 2") AHM Model and Dimensions Model Dimensions W x D x H (MM) Drawing AHURS08DBL 1300 x 1400 x 1200 AHURS10DBL 1500 x 1400 x 1200 AHURS16DBL 1800 x 1400 x 1200 AHURS20DBL 2100 x 1600 x 1200 AHURS32DBL 1800 x 1800 x 1600 AHURS40DBL 2100 x 1800 x 1600 (W) (D) AHURS48DBL 1800 x 1950 x 2300 AHURS60DBL 2100 x 1950 x 2300 14 Outdoor Air Series AHURS-DBL AHURS-DBL Specifications (AC Motor) Model Dimension (WxDxH)mm AHURS 08 DBL 1300 x 1400 x 1200 AHURS 10 DBL 1500 x 1400 x 1200 AHURS 16 DBL 1800 x 1500 x 1200 AHURS 20 DBL 2100 x 1600 x 1200 Total Cooling Capacity Total Sensible Cooling Capacity NETT (KW) 23.0 22.9 22.8 22.8 22.7 23.5 27.9 27.8 27.8 27.7 27.6 28.6 45.0 44.9 44.8 44.7 44.6 46.0 56.9 56.8 56.7 56.5 56.4 58.5 9.2 9.2 9.1 9.1 9.0 8.9 11.2 11.2 11.1 11.0 11.0 10.9 18.2 18.2 18.1 18.0 17.9 17.7 22.8 22.7 22.5 22.4 22.3 22.2 Total Cooling Capacity Sensible Cooling Capacity GROSS (KW) 23.5 9.8 28.6 11.9 46.0 19.2 58.5 24.4 Air Flow Ent.

BACnet IP Module for integration of MicroTech III AHU Controller in networks featuring the BACnet Protocol. Compatible with Daikin intelligent Touch Manager (iTM) or 3rd party BMS. 2. Principal Module POL 638 and Extension ModulePOL 955 have selected analog and digital I/O contacts programmed for control and monitoring of sensors and other related devicesin a VRV Outdoor Air Series AHU. 3. HMI screen on the Principal Module POL 638 allows easy testing and commissioning and even without a centralised controller or 3rd party BMS. 1. Supply air control using the supply air sensor - Used for temperature control. 2. Air quality control CO2 Levels - The controls of the mixing damper can be dependent on the CO2 set point. - User can define the CO2 set point. - The fresh air damper will be difference between 100% and the percentage opening of the mixing damper. 3. Fan airflow control - The fan speed control can be done through i.Direct (w/o inverters). ii.DirectVar(with inverters). iii.Analog controlled variable speed drive with digital release. iv. Pressure control to meet the pressure set points in the duct. 4. Monitoring points for other features i. Room humidity ii. Electric heating coil iii. Outside, room and return temperature iv. VRV alarm MicroTech III can connect to intelligent Touch Manager. (iTM Controller) Monitor and control devices related to AHU such as fan, sensors, and damper - On/Off - Operation mode - Setpoint - Error monitoring - CO2 ppm - Discharged air temp - Humidity - Dumper control etc...
