A high-performance HVAC solution adapted to urban buildings
In a residential building in Plateau-Mont-Royal , our AirGreen team installed a Gree central heat pump on a snow-covered flat roof. This type of intervention perfectly illustrates our expertise when it comes to reconciling energy performance, architectural constraints and the demanding climatic conditions of Greater Montreal.
The objective of this project was to provide occupants with an efficient and sustainable HVAC system, while respecting safety standards and the structural specificities of the building.
Technical characteristics of the installed central heat pump
The central heat pump chosen here comes from the Gree range, renowned for its reliability and robustness in urban environments.
-
Heating and cooling capacity : suitable to cover an entire residential space.
-
Inverter technology : intelligent power adjustment to maximize energy savings.
-
Energy Star Certification : Eligible for provincial and federal grant programs.
-
Extreme cold performance : efficient operation down to -25°C, an essential asset for Montreal winters.
Flat roof installation procedure
Installing a unit on a flat roof involves technical specificities that require a methodical approach.
Support and elevation
The unit was installed on a raised metal structure , allowing the unit to be freed from accumulated snow and to promote air circulation. The wooden rails under the structure ensure weight distribution and protect the roof membrane.
Weather protection
In winter, wind and snow pose additional challenges. The heat pump's elevation and strategic positioning ensure it remains operational even during heavy snowfall.
Routing of pipes
The refrigerant and electrical pipes were carefully insulated and secured, passing through the roof through a watertight hole, to prevent any water infiltration.
Technical challenges and solutions provided
-
Harsh climate : Our team planned the installation in dry and cold weather, taking care to ensure safe work on a snowy and slippery surface.
-
Limited access : Bringing the unit to the roof required the use of suitable equipment and precise coordination to avoid damaging the existing structure.
-
Roof preservation : each attachment was made to protect the roof's waterproofing, an essential consideration in Montreal buildings with flat roofs.
Results obtained for occupants
Thanks to this installation, residents now benefit from:
-
Efficient and economical heating , even during extreme cold spells.
-
Discreet and quiet central air conditioning , ideal for Montreal summers.
-
A long-lasting installation , designed to withstand harsh winters and freeze-thaw cycles.
-
Harmonious integration , without encroaching on the living space or the backyard.
