Heat Recovery Fresh Air Supply System

Energy Recovery Ventilation (ERV) Systems: G-SORA’s Comprehensive Solution for Clean Air in Vietnam

1. The Reality of "Air-Tight but Not Clean" in Vietnam’s Urban Areas

In major cities like Hanoi and Ho Chi Minh City, PM2.5 fine dust pollution frequently reaches alarming levels. To cope, residents often keep windows tightly shut and run air conditioners 24/7. However, this leads to serious consequences:

• CO2 Accumulation: Causes drowsiness, headaches, fatigue, and significantly reduces productivity.
• Sick Building Syndrome (SBS): Stale air traps mold, bacteria, and unpleasant odors within the living space.
• Energy Loss: Opening windows for natural ventilation overloads air conditioning systems, leading to skyrocketing electricity bills.

2. What is an Energy Recovery Ventilation (ERV) System?

The ERV (Energy Recovery Ventilator) is a smart two-way ventilation system:

1. Exhaust Air: Removes stale air, odors, and CO2 from the inside to the outside.
2. Fresh Air Supply: Draws Oxygen-rich air from outside, purifies it through high-standard filters, and distributes it throughout the room.
3. Energy Recovery (Heat Exchange): The core feature. The exhaust air and fresh air streams exchange thermal energy within a recovery core. The incoming fresh air is cooled (in summer) or warmed (in winter) by the temperature of the outgoing air, retaining up to 80% of the indoor thermal energy.
