A flat roof installation perfectly adapted to the urban realities of Montreal
At AirGreen , we recently installed a Sharp ZU1 wall-mounted heat pump in a commercial building in Ville Saint-Laurent , an area where building density and technical constraints require meticulous planning. The chosen equipment—a Sharp ZU1 ECO Inverter —stands out for its Plasmacluster Ion technology , which purifies the air while delivering remarkable energy performance, even in cold climates.
A raised support installation for flat roofs
The outdoor unit was installed on a galvanized aluminum support , fixed to treated beams covered with blue insulating foam to distribute the load and protect the roof membrane. This type of installation is typical for flat roofs in Montreal, where it is essential to ensure:
-
Stability against winds and vibrations .
-
Protection against snow accumulation .
-
Optimal air circulation around the condenser.
Our technicians chose a raised configuration to maintain adequate ground clearance and prevent contact with water or ice during thawing periods. The refrigerated path, discreetly routed to the interior through a sealed duct, was carefully insulated to maximize thermal efficiency .
Why the Sharp ZU1: performance and reliability
The Sharp ZU1 is one of the flagship models of the new generation of R-32 wall-mounted heat pumps , offering:
-
Stable performance down to −25°C , ideal for our Quebec winters.
-
An inverter compressor allowing substantial energy savings.
-
Exclusive Plasmacluster technology that neutralizes bacteria and allergens.
-
A silent heating and air conditioning function (reduced noise level).
Thanks to its energy-efficient design, this unit is eligible for several grant programs such as Rénoclimat and Chauffez vert , subject to seasonal efficiency conditions.
Project progress and specific features
Our team carried out a complete installation in one day , including:
-
Installation of the Sharp ZU1 condenser on a flat roof.
-
The sealed refrigerant connection to the main indoor head.
-
Precise adjustment of the length of refrigerant lines .
-
Electronic commissioning and calibration to ensure optimal performance.
The main technical challenge was the stability of the support on a slightly inclined roof surface. To address this, we integrated a damping system between the metal base and the beams, absorbing vibrations without compromising strength.
A constant commitment to AirGreen quality
Every AirGreen installation is carried out in compliance with RBQ and CSA standards , with particular attention to electrical safety and the durability of the fasteners . Our certified technicians ensure that each project combines:
-
Maximum energy performance.
-
Aesthetics and discretion of the installation.
-
Easy access for seasonal maintenance.
This installation once again demonstrates our expertise in implementing custom HVAC solutions in Montreal, Laval, Longueuil, as well as on the North Shore and the South Shore.
Conclusion: comfort and lasting efficiency
With the Sharp ZU1 heat pump , the customer now benefits from a high-performance four-season system , capable of ensuring constant comfort while reducing energy consumption. This type of installation perfectly illustrates AirGreen's philosophy: reliable, sustainable solutions adapted to the Montreal climate.
