When the condominium association of this Brossard building contacted us, the objective was clear: to ensure reliable heating and efficient air conditioning for the ground-floor technical rooms – particularly the electrical room and the telecom room – while respecting the space constraints around the building. We proposed the installation of a Gree central heat pump , a high-performance system perfectly suited to the winters of the South Shore.
Context: a building with sensitive technical rooms
On the ground floor of the building, the technical rooms house electrical and telecommunications equipment essential to the operation of the building.
These parts:
-
give off a lot of heat in the summer;
-
must remain at a stable temperature all year round;
-
are located in a semi-open concrete area, below the housing units, with a pedestrian walkway nearby.
A solution was therefore needed:
-
compact , so as not to obstruct access;
-
silent , so as not to disturb the occupants;
-
reliable in winter , in order to protect equipment even when the mercury plunges.
The Gree central heat pump has established itself as the ideal solution.
System choice: a Gree Flexx R32 central heat pump
For this project, we opted for a Gree Flexx central heat pump operating on R-32 refrigerant .
This type of system offers several advantages:
-
Efficient heating in Quebec climate : the heat pump continues to provide heat even when the outside temperature drops well below zero, thus reducing dependence on supplementary electric heating.
-
High energy efficiency : in both cooling and heating modes, the Gree central heat pump consumes much less energy than a traditional electric system.
-
R-32 refrigerant : more efficient and with a lower environmental impact than R-410A, it allows for better performance while reducing greenhouse gas emissions.
-
Duct integration : The heat pump is connected to an indoor air manager, which allows heat and air conditioning to be distributed evenly through ducts.
The result: a reliable, discreet and economical central system, perfectly suited to a condominium building.
An optimized outdoor installation on a concrete wall
The Gree outdoor unit was installed on a galvanized wall bracket , securely anchored to the concrete slab. This configuration offers several advantages:
-
Clearance from the ground : the unit is raised to protect it from snow, water and debris, which prolongs its lifespan and facilitates maintenance.
-
Natural protection : the area is partially sheltered by the building structure, which reduces the direct accumulation of snow and ice on the device while maintaining a clear airflow to the front and sides.
-
Vibration reduction : Anti-vibration cushions under the unit limit the transmission of noise to the concrete and dwellings located above.
The refrigeration pipes and electrical wiring are bundled together in a protective sheath, securely fastened up to the point of entry into the technical room. This type of finish:
-
protects pipes against shocks and weathering;
-
significantly improves the aesthetics of the facade;
-
facilitates any future service intervention.
Internal connection: comfort and safety in technical rooms
Inside, the Gree central heat pump supplies an air handling unit installed in the technical room area. This unit distributes the conditioned air via existing or newly installed ductwork.
In practical terms, this allows:
-
to maintain a stable temperature in the electrical room and the telecom room, summer and winter;
-
to prevent overheating of sensitive equipment;
-
to ensure continuous operation in the event of extreme heat or cold spells.
A programmable thermostat allows you to define optimized temperature ranges: cool enough to protect equipment, but without wasting energy when demand is low.
Results for the Brossard condominium
Following commissioning, the building managers benefit from:
-
of a single system for heating and air conditioning technical premises;
-
reduced operating costs , thanks to the very good efficiency of the Gree central heat pump;
-
simplified access for maintenance , since the outdoor unit is unobstructed, at a comfortable height for our technicians;
-
a reduction in noise perceived by the occupants, thanks to the choice of location and anti-vibration measures.
The Gree central heat pump thus perfectly meets the dual objective of comfort and protection of equipment, while respecting the architectural realities of the building.
