1. What is Heat Pump Load Calculation?

Heat pump load calculation determines the heating/cooling capacity required for a space based on area, insulation quality, and temperature difference. Accurate calculation ensures proper heat pump sizing for optimal efficiency and comfort.

2. How Does the Calculator Work?

The calculator uses the heat pump load equation:

Where:

• \( Area \) — Area of the space in square meters (m²)
• \( Insulation Factor \) — Insulation quality in watts per square meter per kelvin (W/m² K)
• \( Temp Difference \) — Temperature difference between inside and outside in kelvin (K)

Explanation: The equation calculates the thermal load by multiplying the area by the insulation factor and temperature difference, then converts to kilowatts.

3. Importance of Load Calculation

Details: Proper load calculation is essential for selecting the right size heat pump, ensuring energy efficiency, preventing short cycling, and maintaining comfortable indoor temperatures.

4. Using the Calculator

Tips: Enter area in square meters, insulation factor in W/m² K, and temperature difference in kelvin. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical insulation factor values?
A: Well-insulated buildings: 0.8-1.2 W/m² K, average insulation: 1.5-2.5 W/m² K, poor insulation: 3.0-4.0+ W/m² K.

Q2: How to determine temperature difference?
A: Calculate the difference between desired indoor temperature and design outdoor temperature for your region.

Q3: Why convert to kilowatts?
A: Heat pump capacities are typically rated in kilowatts or tons, making kW a standard unit for comparison.

Q4: Should I add a safety margin?
A: It's recommended to add 10-20% safety margin to account for unusual weather conditions and heat loss through ventilation.

Q5: Does this work for both heating and cooling?
A: Yes, the same principle applies to both heating and cooling load calculations, though some factors may vary.
