1. What is the M3 Hr to Ton Calculation?

The M3 Hr to Ton calculation converts water flow rate and temperature difference into tons of refrigeration, which is a unit of power used to describe the heat-extraction capacity of refrigeration and air conditioning equipment.

2. How Does the Calculator Work?

The calculator uses the following equation:

\[ Ton = \frac{Q \times \Delta T \times 1000 \times 4.186}{3600 \times 3.517} \]

Where:

\( Q \) — Flow rate (m³/h)
\( \Delta T \) — Temperature difference (°C)
1000 — Conversion factor (kg/m³ for water density)
4.186 — Specific heat capacity of water (kJ/kg·K)
3600 — Seconds in an hour
3.517 — Conversion factor from kW to tons of refrigeration

Explanation: The equation calculates the heat transfer rate based on water flow and temperature difference, then converts it to tons of refrigeration.

3. Importance of Cooling Ton Calculation

Details: Accurate cooling ton calculation is essential for sizing refrigeration and air conditioning systems, ensuring they have adequate capacity to meet cooling requirements.

4. Using the Calculator

Tips: Enter flow rate in m³/h and temperature difference in °C. All values must be valid (flow rate > 0, temperature difference > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is a ton of refrigeration?
A: One ton of refrigeration is equivalent to the cooling power of one ton of ice melting over 24 hours, equal to 3.517 kW or 12,000 BTU/h.

Q2: Is this calculation specific to water?
A: Yes, this calculation uses the specific heat capacity and density of water. For other fluids, different values would be needed.

Q3: What are typical ΔT values in HVAC systems?
A: Common ΔT values range from 5°C to 10°C for chilled water systems, depending on design requirements.

Q4: How accurate is this calculation?
A: This provides a good approximation for water systems. For precise engineering calculations, additional factors may need consideration.

Q5: Can this be used for heating calculations?
A: The same formula can calculate heating capacity, but the result would be in kW or other heating units rather than tons of refrigeration.
