Haier 7kW Round Flow Cassette Air Conditioner Kit – 360° Ceiling Cassette, for Offices & Retail

Haier 7kW Round Flow Cassette Air Conditioner Kit – 360° Ceiling Cassette, for Offices & Retail

The Haier 7 kW Round Flow Cassette Kit (indoor: AB71S2SR1FA / outdoor: 1U71S2SR3FA) is a 360° ceiling cassette air conditioner and heat pump designed for offices, retail, hotels and restaurants. Unlike conventional 4-way cassettes, the Round Flow delivers an 8-way airflow system with 4 independently adjustable directions, covering +23% more area than traditional models with no blind spots. Rated SEER 6.1 A++ cooling and SCOP 4.0 A+ heating, with the twin-rotary inverter compressor operating from -20°C outdoor temperature. The 950 × 950mm panel integrates into standard ceiling grids. Fresh Air technology, integrated hOn Wi-Fi, optional intelligent presence sensor and UVC sterilisation are all included. Kit includes indoor cassette, panel, outdoor condensing unit and wall controller.

Key Features & Technology
8-Way 360° Airflow — +23% Coverage vs Traditional Cassettes
The Round Flow cassette features an 8-way airflow system with 4 independently controllable discharge directions. The enlarged grille surface area delivers 23% greater air distribution than a conventional 4-way cassette, ensuring no cold or warm spots in any corner of the room. Each of the 4 sections can be set independently — directing airflow where it's needed and closing off directions toward windows or external walls.
8-way airflow+23% coverage4 independent directions
Fresh Air Technology — Continuous Ventilation Predisposition
The Round Flow includes a Fresh Air inlet knockout that allows connection of a fresh air duct, introducing up to 20% of nominal airflow as outdoor fresh air directly into the room's conditioned airstream. This is a significant feature for commercial spaces with occupancy requirements — offices, meeting rooms and retail environments where CO₂ and air quality standards apply.
Fresh Air inletUp to 20% fresh air
SEER 6.1 A++ / SCOP 4.0 A+ — With Twin Rotary Inverter Compressor
The twin rotary inverter compressor delivers smooth, precise capacity modulation between 2.0 and 7.3 kW cooling / 2.5 and 8.0 kW heating. Seasonal ratings of SEER 6.1 A++ and SCOP 4.0 A+ reflect real-world operation across the European test climate. Annual consumption is approximately 406 kWh/a cooling and 1,831 kWh/a heating.

950 × 950mm Panel — Standard Ceiling Grid
The 950 × 950 × 50mm panel integrates into a standard commercial suspended ceiling grid. The indoor unit body is 840 × 840 × 204mm, mounting above the ceiling level with the panel flush to the ceiling surface. Panel and indoor unit are supplied together in the kit.

Optional Intelligent Presence Sensor
An optional intelligent sensor can detect room occupancy and adjust airflow direction and output automatically, avoiding direct airflow onto people and reducing energy use when the room is unoccupied. This is particularly valuable in offices and meeting rooms with variable occupancy.
Optional presence sensorAuto airflow adjustment
hOn Wi-Fi Control + UVC Sterilisation — Standard
hOn Wi-Fi is integrated into the indoor unit — control via the Haier hOn app (iOS/Android/Huawei), compatible with Google Assistant and Alexa. UVC sterilisation sanitises the evaporator and internal components, reducing bacteria and mould — relevant for shared commercial environments.

Silent Mode — Quieter Night or Meeting Room Operation
The indoor unit operates at 42/40/38/35 dB(A) across its four fan speeds. A dedicated Silence mode reduces fan speed to its quietest setting, making this unit suitable for meeting rooms, hotel lobbies and other noise-sensitive commercial environments.

Frequently Asked Questions
What area can the 7 kW Round Flow cassette condition?
At 7.1 kW cooling output, this unit is suited to spaces of approximately 55–80 m² with standard commercial ceiling heights (2.7–3.0m), depending on insulation, occupancy and solar gain. For open-plan offices with 30–50 desks, or retail spaces of similar size, a single 7 kW unit is often sufficient. A heat gain calculation should always be performed by the designing engineer.
What is the difference between a Round Flow and a standard 4-way cassette?
A standard 4-way cassette discharges in 4 fixed directions with a flat panel. The Haier Round Flow uses a circular grille with 8 discharge points across 4 independently controllable sections, covering the full 360° of the ceiling plane. The enlarged grille area gives +23% air coverage — reducing temperature stratification and eliminating the 'dead zones' in corners that 4-way cassettes can create.
What does Fresh Air technology do?
The Round Flow has a predisposed fresh air inlet knockout in the chassis. When ducted to an external air source, it can introduce up to 20% of nominal airflow as outdoor fresh air directly into the conditioned airstream — improving CO₂ levels and IAQ (indoor air quality) without a separate mechanical ventilation unit. This requires appropriate ductwork; it is not active without the duct connection.
Does it need F-Gas certification to install?
Yes — all refrigerant-containing systems must be installed by an F-Gas certified engineer (REFCOM, QUIDOS or VERITAS registered). Proof of certification is required at purchase.
Is the intelligent sensor included or optional?
The intelligent presence/occupancy sensor is optional — it is not included in the standard kit. It can be added as an accessory and connected to the indoor unit to enable automatic airflow adjustment based on occupancy detection. Contact us to add this to your order.
