1. What is a Heat Pump Power Consumption Calculator?

Definition: This calculator estimates the electrical power consumption of a heat pump based on the heat load and coefficient of performance (COP).

Purpose: It helps HVAC professionals and homeowners determine the electrical requirements of heat pump systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P = \frac{\text{Heat Load}}{\text{COP}} \]

Where:

Explanation: The heat load (thermal output needed) is divided by the COP to determine the electrical input power required.

3. Importance of Power Consumption Calculation

Details: Accurate power calculation ensures proper electrical system sizing, energy efficiency assessment, and operating cost estimation.

4. Using the Calculator

Tips: Enter the heat load in Watts and the COP value (default 3.0). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is COP in heat pumps?
A: COP (Coefficient of Performance) is the ratio of heat output to electrical energy input. Higher COP means more efficient.

Q2: What's a typical COP value?
A: Most modern heat pumps have COP values between 2.5 and 4.0, depending on temperature conditions.

Q3: How do I find the heat load?
A: Use a heat load calculator or manual J calculation for your building's specific requirements.

Q4: Does this include auxiliary power?
A: No, this calculates only the compressor power. Add fan/pump power separately for total consumption.

Q5: Can I use this for cooling mode?
A: Yes, but use cooling COP (EER/3.412) and cooling load instead of heating load.
