In the process of pharmaceutical storage, the stability of temperature and humidity is directly related to the quality and safety of the drugs.A 1,000-square-meter pharmaceutical cold storage facility requires the selection of a compliant, efficient, and stable temperature and humidity control air conditioning system to be particularly crucial.

Here are key points to note:

I. System Design and Equipment Selection

1、Cooling Capacity Configuration

Recommended refrigeration capacity per square meter 0.3 to 0.5 kW (adjustable according to the density of pharmaceutical stacking), with a total cooling load of approximately 300 to 500 kW for 1000 square meters, multiple systems need to be set up in different areas (such as one system per 300 square meters), to avoid single-point failures.

2、Principle of One for Use and One for Backup

Key equipment such as compressors, cooling fans, and humidifiers must 100% redundant with an automatic switch time of ≤1 minute, meeting GSP emergency response requirements.

3、Humidity Control: Balance Between Dehumidification and Humidification

Adopted Tumble Dry+ Electrode Humidification Set, humidity control accuracy ±5%RH, requires 24-hour continuous dehumidification during the plum rain season (as in the Jiangsu case), to prevent drug deliquescence.

Section II: Temperature and Humidity Control and Monitoring

1、Sensor Layout

Please provide the Chinese content that needs to be translated into American English.GSP mandates at least 4 measurement points per 300 square meters (12 for 1000 square meters), positioned at 2/3 of the height of the drug stacks (approximately 1.8 to 2 meters), with an additional 3 points added in dead corners.

2、Dynamic Response Speed

There is no Chinese content provided. Please provide the news content to be translated. ≤±1℃ (such as in the case of Sichuan Keli Pharmaceutical), using variable-frequency fans + PID control, maintain temperature stability during defrosting by bypassing hot air.

III. Installation and Energy-Saving Key Points

1、Airflow Organization Optimization

Adopted Upper orifice plate air supply+Lower air return method, wind speed ≤0.25m/s, to avoid direct blowing on medicines (refer to standard of temperature and humidity controlled laboratory), shelf aisle width ≥1.2 meters to ensure air circulation.

2、Insulation and Sealing

Polyurethane Insulation Board Thickness ≥15cm (B2 flame-retardant level), moisture-proof layer + epoxy flooring for the ground, double interlocked sealed doors for the storage doors to minimize cold loss.

3、Regional Independent System

If containing different temperature zones (such as)2~8°C refrigeration + 15~25°C shade, requires an independent air conditioning system, and fire-resistant ducts for fire partition isolation.

Four: Acceptance and Maintenance

1、Verification Test

No content provided.The full-load temperature and humidity distribution test must last 48 hours, with the temperature difference between hot and cold spots ≤ 2°C, and issue IQ/OQ/PQ verification reports (required for GSP certification).

2、Backup Power Supply

Configuration Diesel Generator+UPS guarantees startup within 15 minutes of power outage, with at least 2 hours of system operation support for monitoring systems.

V. Cost Control Reference

Cost Range:The 1000㎡ pharmaceutical cold storage with a constant temperature and humidity system costs approximately 1 to 1.5 million yuan (inclusive of backup equipment), which is 80% higher than a standard cold storage due to redundant design.
