Examples of installations carried out by AirGreen
Over the years, we've installed Lennox VRF systems in office buildings, commercial properties, and even high-end residential complexes. Here are a few examples to highlight our expertise:
-
Office building in downtown Montreal : For a client who wanted total temperature flexibility on each floor, we opted for the LENNOX Varix VRF MultiZone | 24 Tons 575V . The building has 12 floors, and the integration of this multi-zone system made it possible to distribute air conditioning and heating according to the actual occupancy of each floor. The managers noticed a significant drop in their energy consumption from the first summer season.
-
High-end residence in Laval : Despite the complexity of a 15-room residence, our team was able to establish efficient zoning by assigning an internal module to each key space. Thanks to integrated Wi-Fi technology, the owner has access to centralized control of all units.
-
Commercial building on the South Shore : In a space spread across several work areas (workshops, administrative offices, and warehouse), we provided a solution combining a LENNOX Varix VRF MultiZone and heat recovery units. Employees thus benefit from a pleasant temperature, without marked differences between the different spaces.
How VRF technology improves energy performance
The principle of VRF (Variable Refrigerant Flow) is to modulate the refrigerant flow to meet the exact needs of an area. If one office requires more cooling, while a neighboring meeting room requires heating, the system adjusts accordingly, without ever operating at full capacity uniformly. This approach offers several advantages:
-
Reduced power consumption : Fewer on/off cycles result in substantial energy savings.
-
Tailor-made comfort : Each zone manages its ideal temperature, without impacting the operation of other spaces.
-
Modularity : With up to 49 zones , the LENNOX Varix VRF MultiZone | 24 Tonnes 575V is suitable for both large complexes and smaller sites, with careful planning.
-
Noise management : Thanks to the digital inverter compressor and the heat exchanger design, the overall noise level remains low, both for the indoor unit and the outdoor module (66.8 dB(A)).
Key points for a successful HVAC installation
To optimize the performance of this VRF system, careful planning is required before any commissioning. Here are some of the things we look at at AirGreen:
-
Analysis of the building structure : Identification of space constraints and determination of the optimal route for the passage of refrigerant pipes.
-
Selection and sizing of indoor units : We take into account insulation, air volume, occupancy rate and the use of each area (offices, workshops, break rooms, etc.).
-
Thermal Balance : Accurate calculation of cooling and heating loads to ensure that the 24-ton capacity meets actual needs, without oversizing or undersizing.
-
Electrical Installation : The LENNOX Varix VRF MultiZone | 24 Tonnes 575V requires a specific power supply (575V). We ensure compliance with current standards and the proper sizing of cables to avoid any failure.
-
Adjustments and Calibration : Central controller setup, refrigerant pressure check (R-410A), WiFi setup for remote monitoring and final performance test.
Integration of heat recovery
Some projects, especially on the North and South Shores , require heat recovery to transfer excess energy from one area to another. The Varix range supports this functionality, allowing extracted heat to be recovered from rooms that need cooling and then routed to other spaces that are underheated. This optimizes overall efficiency and reduces operating costs.
HVAC maintenance and preventive diagnosis
Once the system is installed, HVAC maintenance is of paramount importance to extend the life of the equipment:
-
Periodic cleaning of filters : 4-WAY, 360 CASSETTE or wall-mounted indoor cassettes must be inspected and cleaned regularly.
-
Checking connections : Welding points and pipe fittings should be checked to ensure there are no leaks or pressure drops.
-
WiFi Firmware Update : Samsung integration involves a smart interface. Software updates ensure optimal module responsiveness.
-
Refrigerant Parameter Monitoring : Built-in sensors automatically detect any abnormal drop in refrigerant levels. A simple annual inspection can often prevent costly breakdowns.
-
Real-time performance monitoring : Varix systems feature active intelligence algorithms that adapt to temperature and humidity fluctuations. By monitoring alerts, our technicians respond quickly to any necessary adjustments.
Customer feedback
Among the testimonials we received, several high-rise building owners in Montreal reported noticing a significant difference in their monthly energy bills after installing a Varix VRF system. The synchronization between indoor units, the ability to maintain the same temperature in remote areas, and the quiet operation are particularly appreciated. In addition, the ability to customize the time schedule by zone provides unprecedented comfort for occupants.
