An HVAC installation adapted to the constraints of a Montreal building
In the lively Rosemont–La Petite-Patrie neighborhood, many apartment buildings and condominiums are built with flat roofs . These configurations require special expertise when installing a wall-mounted heat pump , particularly for the positioning of outdoor condensers and the management of refrigeration pipes. At AirGreen , we recently completed the installation of a Midea heat pump, designed to provide optimal comfort while respecting urban constraints.
Choosing the Midea heat pump
The client wanted a solution:
-
reliable in heating and air conditioning;
-
compact for interior space;
-
complies with energy efficiency standards, and therefore eligible for Quebec and federal subsidies .
The installed Midea heat pump stands out for its performance down to -25°C, its superior energy efficiency and its quiet operation, ideal for a dense urban environment like Rosemont.
Challenges and constraints of flat roof installation
Installing an outdoor condenser on a flat roof involves several challenges that our teams master:
-
Stability and safety : the units are placed on treated wooden supports and suitable fixings, in order to avoid any movement linked to vibrations or wind.
-
Drainage and waterproofing : the pipe route must be perfectly insulated to avoid energy loss and protect against water infiltration.
-
Technical accessibility : the location on the roof facilitates maintenance work, while preserving the aesthetics of the facade.
-
Refrigeration distance management : connections to the interior wall head require precise planning to avoid any loss of performance.
Key steps achieved by AirGreen
-
Flat roof preparation : inspection of the condition of the membrane and strategic positioning of the capacitors to ensure stability and future access.
-
Installation of supports : installation of raised bases to prevent direct contact with the gravel and protect the membrane.
-
Laying of pipes and connections : passage of refrigeration lines and electrical wiring with reinforced insulation and aesthetic capping inside.
-
Connection to the wall head installed in the accommodation, with gravity evacuation of condensates.
-
Complete commissioning : vacuum drawing, pressure tests and performance validation in heating and air conditioning modes.
Immediate benefits for the customer
-
Comfort in all seasons : efficient heating in winter, rapid air conditioning in summer.
-
Energy savings thanks to inverter technology that continuously adjusts power.
-
Discreet installation : the outdoor units are invisible from the street, and the interior covers blend harmoniously into the walls.
