An ambitious project in the heart of Laval, with a clear goal: ensure optimal thermal comfort for hotel guests without compromising aesthetics or energy efficiency. That’s the context in which we were asked to design and carry out the installation of multi-zone heat pumps capable of meeting these high demands, while considering the specific nature of the building and its high-volume commercial use.
A Request for Uniform and Discreet Comfort: The Client's Expectations
This hotel, located in a central part of Laval, welcomes dozens of visitors daily, whether for business or leisure. Their comfort is a top priority. The owner was seeking a solution that was:
-
Quiet and invisible to guests
-
Capable of independently regulating the temperature across multiple zones: rooms, hallways, front desk, meeting spaces
-
Energy efficient, with a system eligible for government rebates (notably the LogisVert programs)
-
Quick to install with minimal disruption to hotel operations
Why Multi-Zone Heat Pumps Were the Right Choice
At AirGreen, after a thorough analysis of the needs, we recommended a solution composed of four multi-zone outdoor units connected to a series of discreet and high-performing wall-mounted indoor units.
We selected a combination of Gree Free Match and Fujitsu Airstage models, recognized for their reliability in commercial settings.
Key Benefits of This Solution:
-
Up to 5 independent zones per outdoor unit
-
Power adjusted to each room's size and purpose
-
Inverter technology for optimal performance and reduced energy consumption
-
Sleek wall-mounted design that fits seamlessly into the hotel’s decor
-
R-32 refrigerant systems, more eco-friendly and less polluting than R-410A
Technical Details of the Project
Final Configuration:
-
4 Gree Free Match 36,000 BTU outdoor units, installed on the building's flat rooftop
-
18 Gree Lomo wall-mounted indoor units (9,000 to 12,000 BTU depending on the room)
-
Distance between units: 10 to 25 meters, with vertical elevation respected
-
Customized zone settings in each room via individual remotes and a centralized control panel at reception
-
R-32 refrigerant, more environmentally friendly
-
Confirmed eligibility for the LogisVert rebate, up to $1,500 per outdoor unit
Challenges Faced and Solutions Provided by AirGreen
Every project comes with its own specificities. Here are the major obstacles we encountered during this installation in Laval — and how our team responded:
1. Limited Roof Access for Outdoor Units
The building, being older, had no direct access for moving the units to the roof.
AirGreen Solution:
We used a mobile telescopic crane, scheduled for a Sunday to minimize disruption. Coordination with the City of Laval secured temporary parking permits.
2. Reinforced Concrete Walls
The hotel’s corridors are made of load-bearing concrete walls, making direct duct routing impossible.
AirGreen Solution:
We rerouted the refrigerant lines through the false ceilings of adjacent rooms, without impacting aesthetics.
3. Ongoing Hotel Activity
It was imperative to keep the hotel operational during the installation.
AirGreen Solution:
The installation was planned in four phases, one floor at a time. Rooms in unaffected zones remained open for booking.
Results: Tailored Comfort in Every Space
Just days after installation, the hotel manager reported an immediate improvement in guest comfort:
-
Significant drop in temperature-related complaints
-
Estimated 25% drop in energy consumption compared to the previous central system
-
High staff satisfaction, now able to adjust temperature independently based on daily needs
The hotel’s maintenance team also noted the ease of servicing the indoor units, with filters easily accessible for cleaning.
Why Multi-Zone Installations Are Ideal for Hotels
Room-by-Room Flexibility
Every hotel room has different occupancy, sun exposure, and climate control needs. A multi-zone setup allows:
-
Smarter energy management
-
Reduced energy costs
-
Better guest comfort, a key factor in the establishment’s reputation
Discreet and Stylish
The wall-mounted units installed by AirGreen are ultra-quiet, with a compact design that fits perfectly into modern hotel room aesthetics without drawing attention.
