1. What is a Server Room Air Conditioning Calculator?

Definition: This calculator estimates the cooling capacity needed for a server room based on room size and number of servers.

Purpose: It helps IT professionals and facility managers determine the appropriate air conditioning capacity for server rooms and data centers.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( BTU/h \) — British Thermal Units per hour (cooling capacity)
• \( Room\ Area \) — Floor area of server room (square feet)
• \( Servers \) — Number of servers in the room

Explanation: The formula accounts for both the general room cooling needs (600 BTU/h per sq ft) and server heat output (500 BTU/h per server).

3. Importance of Proper Server Room Cooling

Details: Accurate cooling estimation prevents equipment overheating, ensures stable operation, and optimizes energy efficiency.

4. Using the Calculator

Tips: Enter the room area in square feet and number of servers. All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 600 BTU/h per square foot?
A: This accounts for general heat load from lighting, people, and building envelope. Adjust if room has special conditions.

Q2: Why 500 BTU/h per server?
A: This is an average value. High-density servers may require 1000+ BTU/h each.

Q3: How do I convert BTU/h to tons of cooling?
A: Divide BTU/h by 12,000 (1 ton = 12,000 BTU/h). Our result shows the BTU/h value.

Q4: Should I add a safety margin?
A: Yes, consider adding 10-20% to the calculated value for safety and future expansion.

Q5: What about other equipment like switches and storage?
A: Count them as servers or use their rated power consumption to calculate additional BTU/h (3.41 BTU/h per watt).
