Frequently Asked Questions
How much does it cost to run an air conditioner?
A typical room air conditioner (2.5 kW cooling capacity, about 0.9 kW power consumption) costs approximately 0.30-0.40 euros per hour at current electricity prices. Running it 8 hours daily for 3 months costs 200-300 euros.
What types of air conditioners are there?
The main types are split systems (fixed installation, most efficient), monoblock/portable units (flexible, less efficient), and central air conditioning. Split systems have the best cooling performance per watt.
What is the Air Conditioning Calculator?
The air conditioning calculator computes the required cooling capacity for a room and the annual operating costs of an air conditioner.
How does the Air Conditioning Calculator work?
Enter the room size, ceiling height, window area and orientation. The calculator determines the required cooling capacity in kW and the annual electricity costs at typical usage. Split and portable units are compared.
Key Data and Facts
Rule of thumb: approx. 60-100 watts cooling capacity per sqm. Electricity consumption: 300-500 kWh/summer. SEER value (efficiency): higher is more economical. SEER 6.0 or above = energy class A++.
