An Exceptional Challenge Successfully Met by AirGreen During Intense Heatwaves in Laval
When a heatwave hits Laval, maintaining a consistent temperature of -20°C in commercial cold rooms becomes an extraordinary challenge. At AirGreen, we regularly encounter these complex situations where even minor errors could result in significant financial losses for our clients. Thanks to our deep technical expertise in HVAC installation and our rapid, efficient interventions, we ensure perfect temperature regulation, even during the most critical summer periods.
Why Is Maintaining Negative Temperatures During Heatwaves So Complex?
Keeping a cold room at -20°C during a heatwave goes far beyond traditional air conditioning management. Several critical factors make this task particularly challenging:
Thermal Insulation: Essential Protection, But Sometimes Insufficient
Even the best installations face difficulties when external temperatures regularly exceed 35°C in Laval. Perfect insulation of cold rooms is essential, but during extreme heat, any minor failure can rapidly cause an increase in internal temperature.
Equipment Performance: Extreme Stress on Machinery
Compressors and evaporators used in cold rooms—particularly robust models like Bitzer Ecoline or Copeland Scroll units—are heavily stressed. During extreme heat conditions, these systems must operate continuously, requiring high-quality installations and regular HVAC maintenance to prevent any risk of breakdown.
Precise Management of Humidity and Defrost Cycles
During heatwaves, humidity levels rise significantly in Laval, directly impacting cold-room efficiency. Rigorous control of automatic defrost cycles is crucial to avoid excessive frost formation on evaporators, which would dramatically reduce their cooling effectiveness.
Real-World Example: How AirGreen Secured an Industrial Cold Room in Laval During a Record Heatwave
Recently, we were urgently called by a food industry business in Laval operating an industrial cold room that had to remain precisely at -20°C. With outside temperatures hitting 38°C, the existing system began showing alarming signs of weakness, threatening the integrity of the stored food products.
Rapid and Precise Diagnosis
Upon arrival, our AirGreen team immediately performed a complete analysis of the existing system: a central unit equipped with a powerful Bitzer Ecoline compressor coupled with a Güntner evaporator, configured for standard climate conditions. Quickly, we identified several critical weak points: insufficient insulation around certain access doors and poorly optimized defrost cycle settings.
Immediate Solutions Implemented by AirGreen
Facing the urgency, we swiftly put a precise action plan into place:
-
Immediate Insulation Reinforcement: We installed additional high-performance thermal seals on all doors, effectively eliminating thermal bridges that allowed hot air infiltration.
-
Optimized Defrost Cycles: Our technicians readjusted automatic defrost cycles, shortening their duration to limit temperature fluctuations while maintaining optimal evaporator efficiency.
-
Temporary Installation of Backup Units: Additionally, we temporarily installed an extra 25,000 BTU Copeland Scroll unit, ensuring continuous, stable cooling throughout the critical period.
Result: Perfectly Stable Temperature During the Heat Peak
Thanks to these targeted interventions, the cold room swiftly returned to a stable -20°C despite extreme external temperatures. Our client experienced no financial losses related to temperature variations, and we clearly demonstrated our ability to effectively respond to critical situations.
