Legacy HVAC System Replaced with ECOMFORT R32 Heat Pump at Lyon Airport Business Offices

Project Overview

At a high-traffic commercial office building adjacent to Lyon's airport terminal, Redge deployed a 250 kW ECOMFORT MC R32 air-to-water heat pump.
This installation replaced an aging R407C system and formed part of a larger initiative to modernize building systems, reduce operating costs, and enhance indoor climate control for professionals and visitors.

The project was executed with minimal disruption, meeting strict performance and sustainability targets while respecting the logistical demands of an airport-linked site.

Challenges

Upgrading HVAC equipment in a sensitive location---where occupant comfort and operational continuity are critical---required careful planning and coordination. The client's top priorities included:

  • Avoiding downtime during system changeover

  • Improving seasonal energy efficiency

  • Reducing maintenance frequency and complexity

  • Ensuring a seamless fit with existing mechanical and hydronic infrastructure

  • Transitioning to a refrigerant with a lower environmental impact

Redge Solution

Redge selected a 250 kW ECOMFORT MC R32 indoor heat pump, chosen for its compact footprint, quiet operation, and integrated hydraulic module---ideal for retrofit environments with space constraints.

Core system features included:

  • R32 refrigerant: Lower GWP than legacy gases and zero glide, enabling more stable and service-friendly performance

  • Inverter-driven scroll compressors: Ensure smooth, energy-efficient modulation across all load conditions

  • Smart control architecture: Provides precise thermal regulation and improved energy monitoring

  • Integrated hydraulics: Simplify installation and minimize the need for third-party components

Together, these advantages made the ECOMFORT solution particularly well-suited to a site where thermal reliability and quiet performance are essential.

Key Outcomes

Thanks to the ECOMFORT upgrade, the building now benefits from:

  • Improved energy efficiency and reduced consumption

  • Lower refrigerant emissions through R32 adoption

  • Minimized maintenance needs via integrated design

  • Enhanced year-round comfort for business tenants and airport personnel

The project was completed smoothly in partnership with local stakeholders, allowing the building to remain operational throughout installation and commissioning.
