THE OPPORTUNITY

Could Your VRV
Airflow Do More?

Your building already moves air to support cooling and ventilation. Where a suitable discharge stream is available, it can be assessed as an energy opportunity.

Identify the source
Review the VRV outdoor-unit discharge or connected ventilation duct.
Understand the schedule
Assess the airflow during representative equipment operating conditions.
Match the opportunity
Select a rotor location and system suited to the measured airflow.

TURBINE POSITIONING

Position the Rotor
in the Airflow.

The turbine height and orientation follow the actual discharge path. The outlet and rotor remain clearly visible in the proposed arrangement.

Match the opening height
Align the rotor with the measured airflow leaving the grille.
Provide suitable separation
Determine distance from the outlet through the mechanical review.
Preserve equipment access
Allow maintenance clearance and suitable structural support.

OPERATION CONCEPT

From VRV Airflow to Electrical Use.

Follow the mechanical airflow and the electrical connection through one proposed system.

Isometric VRV airflow and electrical workflow
VRV discharge →Duct airflow →Rotor + generator →Controller / protection →Site-selected inverter →Approved loads
Battery storage is optional. Final equipment and connections follow the site design.

ARCHIMEDES SPIRAL DESIGN

Meet the
LIAM F1 R-1600.

The spiral rotor captures suitable airflow and drives a generator. A complete installation brings together the turbine, supporting structure, control equipment and electrical connection.

Distinctive spiral rotor
The three-blade geometry is central to the LIAM F1 design.
Low starting wind speed
Supplier specification: below 1.5 m/s; starting rotation differs from useful generating output.
A complete engineered system
Mounting, controls and the power connection are selected for the application.

ELECTRICAL CONNECTION & LOADS

Connect Generation
to a Purpose.

The electrical arrangement is designed around the turbine output, the intended loads and the facility’s existing infrastructure.

Control and protection
Review regulation, braking/control requirements, isolation and cable routing.
Inverter or storage arrangement
Select compatible equipment for the required connection; batteries are optional.
Suitable electrical loads
Evaluate common-area lighting, auxiliary circuits or a site-approved building connection.

RELIANCE’S INSTALLATION EXPERIENCE

Experience at
Infineon Singapore.

Reliance Green Energy has delivered LIAM F1 R-1600 installations at Infineon Singapore, using cooling-tower discharge and warehouse mechanical exhaust.

Cooling-tower installation
Existing discharge airflow with turbine support and airflow-guidance works.
Warehouse exhaust application
A separate arrangement located near mechanical extraction discharge.
Experience to inform the next proposal
The proposed VRV application requires its own site assessment.

Energy Contribution.

A meaningful evaluation considers both the electricity generated and the effect of the installation on the existing cooling or ventilation system.

Log the airflow
Capture representative speeds, direction and operating hours.
Monitor generation
Record turbine energy in kWh over the assessment period.
Check equipment performance
Compare HVAC/fan energy and operating conditions against the baseline.
Build the business case
Use measured energy contribution, installation cost and maintenance needs.
MEASURED
