Power Consumption Formula:
From: | To: |
Definition: This calculator estimates the power consumption in watts for a 1.5 horsepower air conditioning unit based on its Coefficient of Performance (COP).
Purpose: It helps homeowners and HVAC professionals understand the electrical requirements and energy efficiency of air conditioning systems.
The calculator uses the formula:
Where:
Explanation: The formula converts horsepower to watts and divides by the COP to determine actual power consumption.
Details: Understanding power consumption helps in sizing electrical circuits, estimating energy costs, and comparing aircon efficiency.
Tips: Enter the COP value (typically between 2.0 and 4.0 for modern units). Higher COP means better efficiency.
Q1: What is a typical COP value?
A: Most modern air conditioners have COP values between 2.5 and 4.0, with higher values indicating better efficiency.
Q2: Why 746 in the formula?
A: 1 horsepower equals 746 watts, so we multiply by this conversion factor.
Q3: How does COP affect power consumption?
A: Higher COP means lower power consumption for the same cooling capacity.
Q4: Where can I find my aircon's COP?
A: Check the manufacturer's specifications or energy guide label on the unit.
Q5: Does this include startup surge current?
A: No, this calculates running watts only. Startup current can be 2-3 times higher momentarily.
