30% Energy Saving Retrofit
How we replaced legacy scroll chillers with Daikin VRV Heat Recovery units at a commercial office building in Gurugram.
Project Summary
The Challenge: The client was facing rising electrical utility bills exceeding 12 Lakhs monthly. The building utilized traditional scroll chillers running at constant speeds, causing massive energy wastes during partial load hours.
The Solution: We performed a complete HVAC load audit using CAD layouts. We decommissioned the older scroll systems and installed a modular Daikin VRV IV heat recovery setup with intelligent touch controllers.
The Results: Electricity consumption dropped by 32% within the first three months. The heat recovery loop utilized rejected cooling energy to provide free hot water for office cafeterias.
Educational Facility Ventilation Audit
Optimizing carbon dioxide ratios and fresh air changes in school lecture halls using Energy Recovery Ventilators (ERV).
Project Summary
The Challenge: High carbon dioxide build-up in packed classrooms caused student drowsiness and reduced concentration levels. Adding fresh outdoor air directly would increase the AC cooling load by 20 TR, exceeding system capacity.
The Solution: We integrated Daikin ERV systems with cellulose heat-transfer cores. The ERV pre-cooled the incoming outdoor fresh air using the temperature of the cold stale air being exhausted.
The Results: Carbon dioxide levels dropped from 1800 ppm to a healthy 750 ppm. IAQ (Indoor Air Quality) was optimized without requiring any capacity upgrades to the main AC cooling unit.
