Daikin BAF287A530 Heat Pump

Daikin’s RT Series (UAYN-AFY1A) is designed and manufactured in Australia with emphasis on reliability and easy installation for commercial applications. As part of the next generation R410A series, the UAYN-AFY1A offers cutting-edge features and improved performance. With a range of seven different model capacities, ranging from 350 to 940 Class (equivalent to 37.2 to 94.9kW). With an Air Flow Range (AFR) spanning from 1950 to 5,300 liters per second (L/s). Additionally, it has an External Static Pressure (ESP) range of 210 to 400 pascals (Pa). One of the most attractive features of the RT Series is its compact footprint, making it an ideal choice for those seeking to replace older R22 systems. Rooftop – UAYN-AFY1A flyer here

Key Features & Technology

It’s the unique features of Daikin products that makes us the world leader.

Designed to enable electricity providers to reduce peak demand, when necessary, RT Series rooftop packaged units feature built-in DRED contacts.

For precise control of refrigerant flow, RT Series is equipped with an EEV, enabling fast & accurate response to heat load changes.

The dual outdoor heat exchangers (HX) allow each HX to enter defrost cycle separately* for improved comfort as reduced heating capacity can still be provided to the indoor environment. *Only applicable when indoor fan is set to run during defrost (default setting), if fan set to off both heat exchangers will run defrost simultaneously

The all-in-one IP44 rated electrical box allows quick and easy access to components such as power supply terminals, RT Touch Controller terminals, after-hours pushbutton contacts and DRED contacts.

Controller

*Can be extended up to 50m using field supplied cable (power: 2 core AWG 12-20 & comm.: 3 core AWG 20-22)

4.3” resistive touch screen LCD controller (480 x 272 resolution)

Wall mounted: 88(H) x 152(W) x 32(D) mm

Flush mounted: 88(H) x 152(W) x 9(D) mm

Check operation at a glance with built-in operation status LED

User operation & service configuration available on the same controller

Wire harness (15m) included for connection to rooftop packaged unit*

RT Series – Outdoor Unit Technology

1 Hydrophilic Blue Fin Heat Exchanger

Aluminium corrugated (waffle) fins with ⌀7mm copper pipes. Dual heat exchangers each with 2 rows (3 rows for 530 Class) at 16 fins per inch. PE coated – an acrylic & hydrophilic coat for corrosion resistance.

2 Dual Fixed Speed Scroll Compressors

2 step control, 50 & 100% capacity. Compressor balance loading function, ensures the accumulated run time of each compressor is similar to extend compressor longevity.

3 Electronic Expansion Valve (EEV)

Expansion valve is electronically operated for precise control of refrigerant flow into the evaporator. Greater efficiency due to better superheat control (compared to Thermostatic Expansion Valve (TEV)). Enables fast & accurate response to heat load changes.

4 Easy to Access Electrical Box

Complete Rooftop System is Ip44 rated. External cables are conveniently fed from the bottom & through the rubber grommets. All-in-one electrical box, gain access to: (1) Rooftop power supply terminals (2) RT Touch Controller terminals (3) After hours push button contacts (4) DRED contact (DRM1, 2, 3* & common) *DRM 1: Compressor Off, DRM2: 50% Power Limit, DRM 3: 75% Power Limit)

5 EC Motor

Electronically Commutated (EC) motor. Exceeds IE4 Efficiency. IP44 Rated (IP55 for 640 – 840 Class). Fan Speed is modulated according to operation mode (cool & heat) & heat exchanger temp.

6 Propeller Fan

Sharp edge fan blade curvature reduces vibration and pressure loss. Large diameter fan quietly delivers high air volume. ESP of up to 30Pa (for ducting).

RT Series – Indoor Unit Technology

1 EC Plug Fan

EBM-PAPST EC plug fan, 2 x fans used for 750 & 840 Class. 5 x backward curve aluminium fan blades. Spider mounted designs & IP55 rated. Soft start motor reduces motor & shaft mechanical stress for improved reliability. Exceeds IE4/super premium efficiency.

2 Internally Insulated Panels

Both supply & return airside compartment is internally insulated with ‘Foil Faced PE Thermobreak’. Closed cell polyolefin foam – reinforced with AL foil. Low thermal conductivity: 0.032W/mK @ 23°C. 20mm thickness for panels & 10mm for drain pan.

3 Hydrophilic Blue Fin Heat Exchanger

Aluminium Slit Fins with ⌀7mm copper pipes. 4 rows at 18 fins per inch, maximises surface area for greater heat exchange in a compact footprint. PE coated – an acrylic & hydrophilic coat for corrosion resistance.

4 MERV 8 Pleated Filters

2″ filter rails are provided with preinstalled MERV 8 pleated filters as standard. Non-woven cotton synthetic blend (50mm pleated). Filters ≥20% of 1.0 – 3.0µm particles. Filters ≥70% of 3.0 – 10.0µm particles.

5 Zinc Coated Galvanised Steel casing

Further electrostatic powered coated in ivory white. Class 3 zinc plated screws used in casing assembly. Durable & weather lasting resistant finish.
