What is HVAC?

Three Core Components:

Heating System: Provides heat to the building during winter to maintain suitable indoor temperatures. Common forms include hot water heating, hot air heating, and underfloor heating.

Ventilation System: Enables indoor and outdoor air exchange, expelling stale air and replenishing fresh air. It also controls indoor pressure differentials and airflow organization, and filters dust and particulate matter, making it crucial for cleanroom contamination control.

Air Conditioning System: Cools and regulates humidity in summer; some systems can achieve year-round constant temperature and humidity, suitable for precision manufacturing or special space requirements.

Core Functions:

Civil Buildings: Ensures a comfortable environment in residential, office, and commercial spaces, regulating temperature and humidity and improving air quality.

Industrial/Professional Locations:

✅Biopharmaceuticals: Controls cleanliness (compliant with GMP), maintains a sterile environment, and prevents particulate/microbial contamination of products.

✅Electronic Chips: Controls temperature, humidity, and cleanliness to prevent static electricity and dust damage to precision components.

✅Hospital Operating Rooms: Maintains sterility and constant temperature and humidity to ensure surgical safety.

Relationship with Cleanrooms

In modular cleanrooms for biopharmaceuticals, the HVAC system is the core component for achieving cleanliness levels (ISO 5-8): It filters air through high-efficiency particulate air (HEPA) filters, organizes unidirectional/turbulent airflow, and rapidly removes particulate matter; simultaneously, it works in conjunction with differential pressure control to prevent the entry of contaminated external air, directly supporting GMP certification compliance requirements.
