Residential Projects Across Central Asia: V8 Eco Supports 80Pa Static Pressure for Balcony or Plant Room Installation

Tight Outdoor Unit Space in Residential Projects? V8 Eco Provides an Engineering Answer with 80Pa Static Pressure

Residential building projects across Central Asia face a recurring engineering constraint: building facades are becoming more compact, leaving increasingly smaller spaces for outdoor unit installation. Units are often placed in enclosed balconies, plant rooms, or narrow ventilation shafts. Under such confined and poorly ventilated conditions, conventional VRF outdoor units frequently trigger protection stops. The V8 Eco series addresses this regional pain point with a technical solution — a customizable external static pressure of up to 80Pa.

What 80Pa Static Pressure Really Means — Available Head Pressure, Not Just Fan Power

Many engineers confuse airflow (m³/h) with static pressure (Pa). Under standard conditions, the V8 Eco delivers 0–20Pa static pressure, suitable for open rooftop or ground-level installation. When the unit needs to connect to longer ducts, install an air deflector, or overcome negative pressure inside a building shaft, the static pressure can be customized up to 80Pa (P22).

This enables:

Forced discharge of hot air from plant rooms to prevent recirculation

Installation on balconies with a static pressure box, without compromising louver efficiency

Multiple units sharing the same ventilation shaft in high-rise buildings without mutual interference

How 80Pa Solves the “Visible but Uninstallable” Problem in Residential Projects

Enclosed Balcony Installation

In many Central Asian residential projects, outdoor units are installed inside enclosed balconies where summer heat dissipation is extremely poor. The V8 Eco's 80Pa static pressure allows the addition of a short duct leading directly outdoors, forcibly expelling hot air and effectively lowering condensing temperature to prevent compressor overload.

Stacked Installation in Plant Rooms

In high-rise residential buildings in cities such as Tashkent and Astana, plant rooms often have limited ceiling height and no natural ventilation. With 80Pa static pressure, each V8 Eco unit can independently connect to its own exhaust duct, creating a “one unit, one duct” positive-pressure heat extraction setup that does not rely on the building's overall ventilation system.

Balancing Noise Control and Static Pressure

80Pa does not mean the fan runs at full speed at all times. The V8 Eco also offers 15-level silent mode (P18), allowing engineers to strike a balance between high static pressure demand and nighttime noise limits — full-pressure heat extraction during the day, quieter operation at night.

Additional Compact Design Advantages for Residential Applications

Beyond static pressure capability, the V8 Eco series offers other benefits for residential projects:

36HP in a single unit with dimensions of only 940×1760×825mm : one unit covers 400m² of cooling/heating load, freeing up more facade space

80Pa static pressure + compact footprint: fits on balconies, equipment platforms, or even narrow building passages

Standby power consumption as low as 3.5W : significantly reduces property electricity costs under long-term partial load conditions

Heating capability down to -30°C: no auxiliary electric heater required, suitable for Central Asia's severe winters

Selection Recommendations (for Central Asian Residential Projects)

Engineering Note: 80Pa static pressure is a customizable option and must be specified at the time of order. It is recommended to reserve duct connections and calculate total pressure loss during the design phase to avoid sizing errors.
