A cutting-edge choice to optimize HVAC comfort

VRF (Variable Refrigerant Flow) systems represent a major advancement in the field of HVAC (heating, ventilation and air conditioning). With the LENNOX Varix VRF MultiZone | 8 Tons 575V | Parts by Samsung , we at AirGreen offer a solution designed to serve up to 16 zones, while providing fine-tuned energy consumption management. This equipment is not simply designed to air condition or heat; it is primarily used to increase the reliability and efficiency of HVAC installations in various types of commercial, industrial and multi-residential buildings in Montreal , Laval , Longueuil , on the North Shore and on the South Shore .

With its advanced features, 575V voltage suitable for commercial environments, and wide connectivity range, this VRF system is suitable for spaces whose configuration requires high zone flexibility. The crucial components (compressor, electronic cards, control modules) are manufactured in collaboration with Samsung, a guarantee of reliability. With 8 tons (96,000 BTU) of cooling capacity and optimal operation down to -30°C in heating mode, this equipment effectively meets the climatic requirements of Quebec, especially in the greater Montreal area where temperatures vary greatly throughout the seasons.

How Lennox MultiZone VRF Works

The LENNOX Varix VRF MultiZone system regulates refrigerant flow in real time and delivers the precise capacity required by each zone served. Each internal component receives the exact amount of refrigerant needed to reach the target temperature, eliminating energy waste associated with full-load operating regimes. In practice, the operating cycle is adjusted for each zone independently.

Unlike fixed flow configurations, where all areas receive the same amount of refrigerant, this VRF system relies on continuous modulation. It therefore allows for more precise temperature control , reduced electricity consumption and better occupant satisfaction. The addition of the "heat recovery" function on certain modules even allows the transfer of heat from an air-conditioned zone to a heated zone. In the case of the LENNOX Varix VRF MultiZone | 8 Tonnes 575V , the parts supplied by Samsung increase the reliability of sensitive elements, particularly the compressor and control electronics.

Concrete benefits for buildings in Quebec

1. Cold weather performance
   Quebec winters are harsh. Thanks to a specially optimized design, the LENNOX Varix VRF MultiZone ensures consistent performance even when the mercury plummets to -30°C. Many homeowners in Laval and on the North Shore require a robust system to withstand periods of intense cold; this model meets precisely that need.

2. Multiple Zone Management
   This system supports up to 16 zones simultaneously. This means that in an office building or a business spanning several floors, each section can be configured independently. For example, at AirGreen, we installed this system in an educational institution in Longueuil , where certain areas require more heat in the morning and more air conditioning in the afternoon. The result: reduced energy costs and increased user satisfaction.

3. Voltage 575V
   The commercial and industrial market in Quebec often uses 575V to power machinery. Our AirGreen team has found that this voltage format simplifies the system's integration into existing electrical networks, thus avoiding costly modifications.

4. Advanced sensing and control technology
   Samsung's electronic boards and management interface provide intelligent control of heating and cooling modes. Learning algorithms adapt operation based on actual heat load, optimizing startups and limiting defrost cycles.

5. Silent operation
   The outdoor noise level is approximately 59 dB(A) . In residential areas or near sensitive areas, noise can become an issue. This VRF system, thanks in particular to the specific design of the fan and compressor, remains discreet during operation, which greatly improves the quality of life of the occupants.

Case study: Multi-zone building in Laval

To illustrate the HVAC installation of a LENNOX Varix VRF MultiZone | 8 Tons 575V | Parts by Samsung , let's take the example of a three-story office building in Laval . In this project, the main objective was to reduce energy costs and improve thermal comfort, which is often uneven depending on the orientation of each floor. We recommended this VRF model for:

• Take advantage of multisplit capacity (up to 16 indoor units of cassette, wall-mounted or ducted types).

• Exploit the existing commercial voltage of 575V.

• Offer high-efficiency operation even in negative temperatures, which avoids the need for an excessively expensive auxiliary heating system.

The result: the building saw a significant drop in energy bills and improved control of air conditioning and heating. Occupant feedback indicated a decrease in complaints related to temperature fluctuations, especially in areas where more heating was required in the morning. In addition, thanks to the robust components (fans, coils, control boards), HVAC maintenance is easier and downtime is virtually zero.

Installation and maintenance details by AirGreen

AirGreen's approach

At AirGreen, we have always taken a holistic approach to HVAC installation . For a VRF project like the LENNOX Varix VRF MultiZone , we start with a thorough heat load study and then develop a detailed layout plan, taking into account the ideal positioning for the outdoor units and refrigerant line routes. Our certified technicians then handle installation, start-up, and final adjustments.

Commissioning phase

1. Electrical validation : verification that the 575V power supply meets the standards and capacity of the equipment.

2. Pipe connection : installation and crimping of refrigerant pipes, taking care to minimize pressure losses and ensure continuity of insulation.

3. Leak test : pressure test to confirm that no leaks compromise operation.

4. Initial settings : configuration of the central remote control and individual thermostats, definition of temperature thresholds and operating time slots.

Recommended HVAC maintenance

The longevity of a VRF system depends on rigorous HVAC maintenance . We recommend biannual maintenance, focusing on:

• Checking filters and coils.

• Early detection of leaks or abnormal pressure drops.

• Checking the operation of expansion valves and electronic sensors.

• Inspection of the battery and the connectors of the Samsung cards.

By ensuring preventive maintenance, we not only ensure that the equipment's lifespan is extended, but also that high performance is maintained, both during periods of extreme winter cold and in summer, when the demand for air conditioning can be intense on the South Shore and in Montreal .
