Understanding air conditioning consumption

Air conditioning consumption is an important topic to understand in order to manage your energy costs and optimise your comfort. Several factors are at play, from the unit’s power to the home’s insulation. It is therefore essential to analyse these elements to make an informed choice and use your air conditioning effectively.

Factors influencing energy consumption

Several factors can impact the energy consumption of your air conditioning. The first is, of course, the unit’s power. A more powerful air conditioner will consume more energy. The area to be cooled is also a determining factor. A large space will require more energy to reach the desired temperature. Your home’s insulation plays a crucial role: poor insulation will lead to heat loss, forcing the air conditioner to run longer and therefore consume more. Finally, the number of openings, such as windows and doors, can also influence consumption, as these are often points of thermal loss. It is important to choose an air conditioner suited to your needs.

Estimating annual consumption

Estimating an air conditioner’s annual consumption can prove complex, as it depends on many parameters. However, it is possible to obtain an estimate by taking into account the unit’s power, the daily usage duration and the number of days used per year.

It is important to note that these estimates are indicative and may vary based on actual usage conditions. For a more precise estimate, it is advisable to consult a professional or use an online simulation tool.

To give you an idea, a 2000 Watt air conditioning unit can consume between 500 and 800 kWh over a year, whereas a 5000 Watt model can reach between 1100 and 1700 kWh. The average consumption for one hour of air conditioning ranges between 1.5 and 2.5 kWh, according to ADEME.

Impact of openings on consumption

Openings, such as windows and doors, can have a significant impact on an air conditioner’s energy consumption. Indeed, they are points of thermal loss, meaning areas where heat can escape or enter more easily. To minimise this impact, it is recommended to:

• Keep windows and doors closed when the air conditioning is running.
• Use curtains or blinds to block sunlight and reduce heat gain.
• Check the sealing of windows and doors and carry out repairs if necessary.
• Consider replacing windows with more efficient insulating models. It is important to understand the symbols of your air conditioner.

Electric consumption of a reversible air conditioner

The consumption of a reversible air conditioner is an important aspect to consider when purchasing and using this appliance. Several factors influence the amount of electricity consumed, and it is essential to understand them to optimise its use and control energy costs.

Economic advantages of reversible air conditioning

One of the main advantages of reversible air conditioning lies in its ability to heat and cool a space, thus providing a two-in-one solution. This versatility can translate into significant savings on heating costs, particularly in regions with mild winters. Indeed, reversible air conditioning uses a thermodynamic principle that allows it to transfer heat rather than produce it directly, which is generally more efficient than traditional heating systems. It is important to fully understand the economic advantages to make an informed choice.

Comparison with conventional heating systems

Compared to conventional heating systems, such as electric radiators or gas boilers, reversible air conditioning often offers better energy efficiency.

• Electric radiators convert electricity directly into heat with an efficiency close to 100%, but they have high consumption.
• Gas boilers require the combustion of natural gas, which can be costly and generate greenhouse gas emissions.
• Reversible air conditioning, on the other hand, uses a reversed refrigeration cycle to extract heat from the outside and release it inside, or vice versa.

This process is more efficient, as it requires less energy to produce the same amount of heat or cold. However, the efficiency of reversible air conditioning can vary depending on the outdoor temperature and the quality of the home’s insulation.

Hourly running cost

The hourly running cost of reversible air conditioning depends on several factors, including:

• The power of the unit
• The electricity price per kWh
• The unit’s energy efficiency (its coefficient of performance, or COP, in heating mode, and its seasonal energy efficiency ratio, or SEER, in cooling mode).

On average, reversible air conditioning consumes between 0.8 and 1.5 kWh per hour. To estimate the hourly cost, simply multiply this consumption by the kWh price. For example, if the kWh price is €0.20 and the air conditioning consumes 1 kWh per hour, the hourly cost will be €0.20. It is important to monitor the hourly cost to optimise use of the unit.

| Factor | Influence on hourly cost | Aspect | Conventional heating system | Reversible air conditioning | Economic benefits |—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|—|anchor are not.

Indeed, the consumption of a reversible air conditioning unit can vary considerably depending on the type of unit, its power, and its use. On average, consumption can range between 1500 and 2500 watts per hour, or 1.5 to 2.5 kWh. This can translate to a cost ranging from €0.38 to €0.63 per hour. For a reversible air conditioner, consumption is generally lower, around 0.8 to 1 kWh. It is therefore important to fully understand the consumption factors to optimise its use.

The cost of running a mobile air conditioner

Average hourly cost of mobile air conditioning

The cost of an hour’s use of a mobile air conditioner varies according to several factors. The unit’s power is paramount. A 1000 watt air conditioner consumes around 1 kWh per hour, which equates to approximately €0.10 based on current EDF rates (April 2024). However, for a more powerful unit, such as a 2500 watt air conditioner, consumption can reach €0.63 per hour. It is important to note that these figures are averages and may vary according to the unit’s efficiency, room size, and temperature setting. For a 100m2 house, the average cost can vary significantly.

Cost variations depending on power

The power of a mobile air conditioner directly influences its electrical consumption and, consequently, its running cost. A more powerful unit will cool a room more quickly, but will consume more energy. It is therefore essential to choose a model suited to the size of the room being cooled to optimise consumption.

Here are some points to consider:

• A low-power air conditioner may be sufficient for a small room, but ineffective for a large space.
• An air conditioner that is too powerful will waste energy in a small room.
• It is recommended to consult energy labels to compare the efficiency of different models.

Your home’s insulation level, the outdoor temperature, and the appliance’s usage duration are factors that significantly influence the final cost. For 12 hours of use per day, the cost can amount to around €1.45 per day, or €43.50 per month, with a range of ±20% depending on your home’s insulation and the outdoor temperature.

Impact on the electricity bill

Using a mobile air conditioner has a direct impact on your electricity bill. Mobile air conditioner models typically consume between 1500 and 2500 watts per hour. For a 1500 watt mobile air conditioner, the electricity bill can rise to around €105 for summer use, based on the regulated EDF tariff. This is an average estimate, which can vary depending on your electricity provider and the unit’s power. To reduce your mobile air conditioner consumption, several strategies can be adopted. Optimising the temperature setting: As a general rule, a difference of 5 to 8°C between indoor and outdoor temperatures is sufficient to ensure comfort without wasting energy. It is therefore crucial to choose the right unit and use it optimally to control energy consumption and reduce the impact on your electricity bill.

Optimising energy consumption

It is imperative to optimise the energy consumption of your reversible air conditioning to reduce your bills and minimise your environmental impact. Several strategies can be implemented to achieve this goal.

Importance of energy rating

An air conditioner’s energy rating is a key indicator of its efficiency. A+++ rated units are the most efficient and consume the least energy. Investing in a high energy rating unit may seem costly initially, but it results in significant long-term savings. It is therefore important to thoroughly compare energy ratings before making your choice.

Role of home insulation

Good insulation is essential to limit heat loss in winter and maintain coolness in summer. Poorly insulated walls, windows, and attics lead to higher energy consumption to compensate for thermal losses. Improving your home’s insulation is therefore a cost-effective investment that will help reduce your air conditioning and heating consumption. Consider checking your thermal insulation.

Benefits of temperature regulation

Temperature regulation allows you to precisely adjust your air conditioning’s operation according to your actual needs. Using a programmable thermostat or a centralised management system lets you set operating time slots and target temperatures for each room. This prevents overheating or overcooling your home unnecessarily, resulting in substantial energy savings. Temperature regulation is a key element for controlled energy consumption.

Optimising energy consumption involves a holistic approach that combines choosing a high-performance unit, good home insulation, and precise temperature regulation. By implementing these strategies, you can significantly reduce your electricity bill and contribute to environmental protection.

Here are some additional tips to optimise your consumption:

• Clean your air conditioner filters regularly to ensure optimal operation.
• Use the “energy-saving” mode if your unit is equipped with it.
• Close shutters and curtains during the hottest hours to limit heat ingress.

Calculating air conditioning costs

To best anticipate your budget, it is essential to understand how to estimate your air conditioning’s running cost. Several factors are involved, and an accurate estimate will help you avoid nasty surprises on your electricity bill.

Cost estimation formula

The basic formula to estimate air conditioning cost is as follows: (Unit power in kW) × (Number of hours of use) × (kWh price). This formula will give you an estimate of the cost for a given period. It is important to note that this formula does not account for power variations due to Inverter technology or temperature regulation.

To calculate an air conditioner’s consumption, conditioning in watts, divide the power in watts by 1000 to obtain a result in kWh, then multiply this number by the kWh price of your electricity supplier.

Example cost for a summer period

Let’s take the example of a 1 kW air conditioner used 4 hours per day for 90 days (the length of summer). If the kWh price is €0.20, the calculation would be: 1 kW × 4 hours × 90 days × €0.20/kWh = €72. This cost can vary significantly depending on your unit’s power and usage. For a 100m² house, the annual cost can rise quickly.

It is important to note that this calculation is an estimate. Actual consumption can vary depending on your home’s insulation, the outdoor temperature, and your unit’s energy rating.

Electricity rates and their influence

Electricity rates vary considerably from one supplier to another. It is therefore crucial to compare offers to find the most advantageous rate. Additionally, some suppliers offer peak/off-peak rates, which can impact your air conditioning cost if you mainly use it during peak hours. It is possible to further reduce your electricity bill by using a temperature regulation system.

Here is a comparative table of hourly air conditioning costs according to different suppliers (indicative rates):

Supplier	Price per kWh (€)	Hourly cost (1 kW air con) (€)
EDF (Blue Tariff)	0.2016	0.2016
Yéli (Sympa 25% green)	0.1772	0.1772
OHM Énergie (Extra Eco)	0.1654	0.1654

It is important to monitor the kWh price and adjust your consumption accordingly.

Choosing a suitable air conditioning system

Importance of the thermal assessment

Before selecting an air conditioning system, it is essential to carry out a thermal assessment of your home. This diagnosis allows you to accurately assess the cooling needs of each room, taking into account insulation, sun exposure, the volume to be cooled, and the number of occupants.
