HVRF Indoor Units

Industry-Leading 2-Pipe Hybrid VRF Technology

Mitsubishi Electric City Multi Hybrid VRF is an industry-first technology that revolutionises VRF systems by combining the benefits of both VRF and chilled water systems. This innovative approach uses refrigerant between the outdoor unit and the Hydro BC Controller (HBC) and water for indoor distribution, creating a unique 2-pipe hybrid system that sets new standards for comfort, safety, and efficiency in building climate control.

Enhanced Safety Through Advanced Design

The system’s distinctive design eliminates refrigerant from occupied spaces by using water between the HBC and indoor units, ensuring full compliance with AS/NZS 5149 standards without the need for refrigerant leak detection systems. This makes it particularly suitable for sensitive applications such as healthcare facilities, schools, and hotels, where occupant safety and regulatory compliance are critical. The HBC serves as the system’s core, housing all critical components including heat exchangers, pumps, and control valves in one consolidated unit.

Efficient Operation with Superior Comfort

Available in both air-cooled and water-cooled configurations, with R410A or R32 refrigerant options, the system delivers exceptional energy efficiency through heat recovery during simultaneous cooling and heating operations. The water-based distribution system provides naturally stable temperatures and milder off-coil temperatures, ensuring consistent comfort across all zones while simplifying installation compared to traditional 4-pipe systems. Comprehensive control options, including centralised building management systems and individual controllers, enable optimised application performance.

Types of HVRF indoor units

Ceiling cassette type

PLFY-WL-VEM-E 4-Way Air Flow Ceiling Cassette

Ceiling cassette air conditioning systems are an ideal option for air conditioning rooms with no available walls to mount a split system or with limited ceiling space for a ducted system. Their whisper-quiet operation is ideal for master bedrooms, living rooms, and other single-room residential or commercial uses.

Features 72 different airflow patterns with individually adjustable vane angles, configurable for 4, 3, or 2-way throws. High and low-ceiling modes adjust airflow volume to match room height, while horizontal airflow reduces cold drafts. The optional 3D i-See Sensor monitors occupant position, body temperature and floor temperature to enable energy-saving operation based on room occupancy.

PLFY-WL VFM-E 4-Way Ceiling Cassette

The PLFY-WL VFM-E series is designed to fit seamlessly into 2 x 2 ceiling construction specifications, with compact dimensions of 600 mm x 600 mm and a slim profile of 245 mm in height. This allows for easy installation even in narrow ceiling spaces. A key feature of this series is its horizontal airflow capability, which directs air supply horizontally into the room, minimising cold drafts and enhancing comfort in office and restaurant environments.

The series offers two optional features for enhanced functionality. An external flow control valve can be added to enable more accurate power apportioning via the AE-200E central controller, ideal for projects requiring individual billing. The optional 3D i-See Sensor also provides advanced occupancy detection, monitoring people’s location, number, and body temperature in the room. This intelligent sensor works with an algorithm to optimise power consumption while maintaining comfort and offers direct and indirect airflow settings for improved air distribution tailored to room occupancy.

Ducted or ceiling concealed type

PEFY-WP VMS1-E Low Static Pressure Ceiling Concealed

Perfect for hotels and spaces requiring discreet air conditioning solutions, this low static pressure ceiling concealed unit combines slim design with quiet operation. Installation flexibility allows for either rear or bottom air inlet configurations.

When using the rear inlet configuration, ultra-quiet operation ranges from 20 dB (low airflow) to 35 dB (high airflow). Note that bottom inlet installation results in higher noise levels, making the rear inlet preferable for bedrooms and quiet spaces. The slim 200mm height profile with a maximum 50 Pa external static pressure enables installation in tight ceiling spaces. Available in capacities up to 5.6 kW.

Key features include flexible installation options, with refrigerant/drain piping and a control box available on either the right or left side—ideal for symmetrical room layouts common in hotels. Optional card key integration prevents wasteful operation by automatically switching the unit off when guests leave their rooms.

PEFY-W VMS-A Low Static Pressure Ceiling Concealed

Ideal for offices, hotel rooms, and bedrooms where ultra-quiet operation and minimal ceiling space are priorities. For installations requiring the lowest possible noise levels (such as hotels), the VMS-A model without a drain pump is recommended, while the VMS1 series includes the drain pump as standard.

The slim 200mm height profile is consistent across all models (W15 to W63), enabling installation in tight ceiling spaces or bulkheads. External static pressure can be adjusted to 5, 15 (factory default), 35, or 50 Pa. The unit is available in capacities up to 5.6 kW, with noise levels as low as 22-30 dB(A) at low speeds. A drain pump is available as an optional accessory.

PEFY-WP-VMA-E Medium Static Pressure Ceiling Concealed

Medium static pressure ceiling concealed units are designed for applications requiring greater external static pressure and flexible installation options. They are available in two variants: models with built-in drain pumps (VMA-E) and models without drain pumps (VMAL-E) for greater piping layout flexibility.

The consistent 250mm height profile across all models (WP20 to WP125) allows for installation in restricted ceiling spaces. Five selectable external static pressure settings up to 150 Pa provide extensive duct design and air outlet configuration flexibility.

PEFY-W-VMA(L)-A Medium Static Pressure Ceiling Concealed (High Efficiency Model)

High-efficiency medium static pressure ceiling concealed units designed for applications requiring greater external static pressure and flexible installation options. They feature a built-in flow control valve enabling individual billing through the AE-200E central controller’s charge calculation function.

Available in two variants: models with built-in drain pump (VMA-A) and models without drain pump (VMAL-A) for greater piping layout flexibility. The consistent 250mm height profile across all models (W20 to W125) allows installation in restricted ceiling spaces. Five selectable external static pressure settings up to 150 Pa provide extensive duct design and air outlet configuration flexibility.

PEFY-W-VMA2-A Medium Static Pressure Ceiling Concealed

Medium static pressure ceiling concealed units featuring a built-in flow control valve for individual billing capability through AE-200E central controller’s charge calculation function. Available in two variants: models with built-in drain pump (VMA2-A) and models without drain pump (VMA2L-A) for greater piping layout flexibility.

The consistent 250mm height profile across all models (W20 to W125) allows installation in restricted ceiling spaces. Five selectable external static pressure settings up to 150 Pa provide extensive duct design and air outlet configuration flexibility.

PEFY-WL-VMHS-A High Static Pressure Ceiling Concealed

High static pressure ceiling concealed units designed for projects requiring powerful, adaptable ducted air conditioning systems that can be tailored to suit diverse architectural layouts and performance needs. With external static pressure exceeding 200 Pa, these units are ideal for complex installations requiring extensive ductwork and customised air distribution.

The optional drain pump offers enhanced lift capacity—up to 550mm for WL40-125VMH(S) models and up to 700mm for WL200-250VMHS models—reducing horizontal piping requirements. An external flow control valve can be added for individual billing applications to enable charge calculation functionality through the AE-200E central controller.
