In Verdun, on the flat roof of a modern residential building, our AirGreen team recently installed aSharp wall-mounted heat pump . This project perfectly illustrates our expertise in dense urban environments: optimizing occupant comfort while respecting the architectural and technical constraints of a condominium building.
Project context in Verdun
The building is located in a typical area of Verdun , consisting of recent condominiums with flat, gravel-covered roofs. The occupants wanted:
-
An economical and quiet heating and air conditioning system
-
A high-performance solution to cope with Montreal's harsh winters
-
A discreet device that does not detract from the building's aesthetics or the comfort of the neighbors.
After analyzing the building configuration and thermal load requirements, we recommended the installation of a Sharp wall-mounted heat pump, ZU1 ECO Inverter series , ideal for this type of residential project.
Why choose the Sharp ZU1 ECO Inverter wall-mounted heat pump?
The Sharp ZU1 ECO Inverter range is a recognized wall-mounted solution for:
-
Its high energy efficiency thanks to Inverter technology
-
Its heating performance in cold weather is particularly suited to the Montreal climate.
-
Its operation is silent , both indoors and outdoors.
-
Plasmacluster Ion technology , contributing to better indoor air quality
In this project, the chosen capacity offers an excellent compromise between power and energy savings for a medium-sized condo, with comfortable coverage in both summer and winter.
Technical challenges of a flat roof installation
Installing a condenser on a flat gravel roof involves several technical considerations:
-
Roof membrane protection : it is essential not to puncture or damage the surface to avoid any risk of water infiltration.
-
Free air circulation around the unit: the condenser must be positioned at a good distance from walls, existing equipment and obstacles to ensure optimal airflow.
-
Snow and ice management : in winter, the device must be raised to remain clear of snow accumulation.
-
Access for maintenance : the location must allow for safe and efficient maintenance interventions.
Our team took all these elements into account to design a sustainable, safe and compliant installation.
Key steps of the installation carried out by AirGreen
1. Positioning of the Sharp outdoor unit
We installed the Sharp ECO Inverter outdoor unit on a raised support , securely fixed and equipped with anti-vibration pads .
This support:
-
Distributes the load over the gravel surface
-
Protects the roof membrane
-
Reduces the transmission of vibrations and noise to the building structure
The unit is oriented to benefit from sufficient clearance around the fan , which optimizes energy efficiency and extends the life of the compressor.
2. Management of refrigeration and electrical connections
The refrigerant lines connecting the Sharp outdoor unit to the indoor wall unit were:
-
Calibrated to the correct length
-
Insulated with quality materials to limit energy loss
-
Protected within conduits for a clean and tidy appearance
On the electrical side, our technicians have:
-
Connect the condenser to a safety disconnect switch accessible on the roof
-
Verified the conformity of the dedicated power supply
-
Performed grounding and protection tests
The result: a safe installation, compliant with the electrical code , ready to operate reliably all year round.
3. Commissioning and adjustments of the Sharp heat pump
During commissioning, we have:
-
A complete vacuum was drawn in the refrigeration circuit.
-
Checked the tightness of the fittings
-
Adjusted the operating parameters of the indoor unit to ensure:
-
A consistent airflow throughout the condo
-
A minimal noise level
-
Intelligent management of defrost cycles in winter
-
We then assisted the occupants in learning how to use the remote control : operating modes, programming, usage tips to maximize energy savings.
Results for the occupants of Verdun
Since the installation, the occupants have benefited from:
-
Stable thermal comfort in summer as well as winter
-
Lower energy bills compared to a purely electric system or baseboard heaters
-
Improved air quality thanks to Sharp's Ion Plasmacluster technology
-
A discreet system : the outdoor unit on the roof does not detract from the aesthetics of the facade, nor disturb the peace and quiet of the neighbors.
For the condominium association, the chosen solution also offers advantages:
-
No bulky installation on the facade
-
Seamless integration with other rooftop equipment
-
Added value for the building, with a modern and efficient system
