1. What is Heat Pump Power Consumption?

The power consumption of a heat pump is the electrical energy required to deliver a certain amount of heat. It's determined by the heat output and the system's coefficient of performance (COP).

2. How Does the Calculator Work?

The calculator uses the heat pump power equation:

Where:

• \( Power \) — Electrical power consumption (kW)
• \( Q_h \) — Heat output (kW)
• \( COP \) — Coefficient of Performance (dimensionless)

Explanation: The COP represents how efficiently the heat pump converts electrical energy into heat energy. Higher COP values mean more efficient systems.

3. Importance of Power Calculation

Details: Calculating power consumption helps in sizing electrical systems, estimating operating costs, and comparing heat pump efficiency.

4. Using the Calculator

Tips: Enter heat output in kW and COP (typically between 2-5 for most residential heat pumps). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical COP value for heat pumps?
A: Most modern heat pumps have COPs between 3-4, meaning they deliver 3-4 units of heat per unit of electricity consumed.

Q2: How does outdoor temperature affect COP?
A: COP typically decreases as outdoor temperature drops, as the heat pump must work harder to extract heat from colder air.

Q3: Is higher COP always better?
A: Generally yes, but higher COP systems may have higher upfront costs. The optimal COP depends on your climate and energy prices.

Q4: Can this calculator be used for cooling mode?
A: Yes, but use the cooling capacity and cooling COP instead of heating values.

Q5: How accurate is this calculation?
A: It provides theoretical power consumption. Actual consumption may vary based on installation, maintenance, and operating conditions.
