Product Description

HRV Ventilation System Overview

Importance of Indoor Air Quality

Modern buildings are designed with high airtightness, utilizing aluminum casing windows and rubber lining doors to maximize energy efficiency. While this limits cooling or heating loss, it often results in poor indoor air quality. Effective ventilation is essential to providing a healthy living environment.

Sick House Syndrome Infographic

The "Sick House Syndrome" Risk: Insufficient ventilation impacts human health and building longevity. Common issues include:

Yellow stains on walls caused by tobacco smoke.
Allergic illnesses induced by mold and mites due to moisture buildup.
Unpleasant odors from bathrooms and cooking areas.
Reduced concentration and fatigue due to oxygen shortage.
Building structural deterioration resulting from condensation and mold.
Airtight Home Issues

Addressing Home Airtightness

Highly airtight houses restrict fresh air ingress. While this maintains the expected indoor temperature for energy saving, it traps hazardous pollutants. Our HRV system ensures optimized Indoor Air Quality (IAQ) without sacrificing energy efficiency.

Bypass Ventilation Function

Equipped with a diversion damper, the Bypass Ventilation allows the Return Airflow (RA) to exceed the Supply Airflow (SA). This ensures the speedy exhaust of indoor polluted air. Using this mode during season changes improves comfort and maximizes energy savings.

Frequently Asked Questions

1. Why is HRV ventilation necessary for modern airtight homes?
Modern homes use advanced sealing to save energy, which traps indoor pollutants and reduces oxygen. HRV systems provide a steady supply of filtered fresh air while exhausting stale air, maintaining a healthy balance.
2. What are the benefits of the Bypass Ventilation function?
Bypass ventilation allows the system to exhaust polluted indoor air rapidly without heat exchange. This is particularly effective during mild seasons to cool down the house naturally and save energy.
3. How does the system prevent "Sick House Syndrome"?
By consistently replacing indoor air, the system reduces the buildup of mold, dust mites, CO2, and VOCs, which are the primary causes of respiratory issues and building deterioration.
4. What filtration levels does this system support?
Our systems can be equipped with various filters including G4 for large particles, and H11/H13 HEPA filters for fine dust and allergens, ensuring the highest air purity.
5. Can the ventilation system be integrated with air conditioning?
Yes, the system supports interlocking with air conditioning units and can be managed through Intelligent controllers or BMS for automated, energy-efficient operation.
6. Is the system suitable for commercial applications?
Absolutely. With airflow options ranging from 150 to 25,000 cbm and robust control options like CO2 and humidity sensing, it is ideal for commercial offices and residential buildings.
