A discreet and efficient wall installation by AirGreen
At AirGreen , we recently completed a Sharp ZU1 wall-mounted heat pump installation in a residence in the Chomedey sector of Laval . The project perfectly illustrates our approach: careful integration , optimal energy performance and impeccable technical execution , even in residential configurations with specific wall constraints.
Project background
The client wanted to upgrade their air conditioning system to provide a four-season solution : efficient cooling in the summer and reliable heating in the winter. After careful analysis, our team recommended the Sharp ZU1 R-32 series , which is known for its energy efficiency and ability to operate down to -25°C .
This compact and quiet unit is ideal for semi-detached or row houses, such as the one in this project, where the brick façade and limited space require careful planning of the refrigeration path.
Technical details of the installation
The outdoor unit was mounted on galvanized wall brackets at a safe height for winter snow. The electrical wiring was neatly integrated, running along the masonry and joining the panel via a discreet white conduit.
The refrigeration circuit — sheathed and insulated — was installed with a slight gravity slope to allow the natural evacuation of condensates, without an additional pump.
The distance between the indoor unit and the compressor has been optimized to reduce heat losses, ensuring stable and quiet performance.
A light grey capping , matching the building's cladding, provides a neat finish while ensuring mechanical and thermal protection of the pipes.
Advantages of the Sharp ZU1 system
-
Exceptional energy efficiency (R-32) : reduced consumption by up to 30% compared to older R-410A models.
