Air conditioning in the office is a solution that is slowly becoming the standard of today. Currently, few people can imagine working in hot weather without air conditioning, but how to choose the right option? What factors should be taken into account when choosing the optimal solution and what filters should office air conditioning have?

Calculating room volume and selecting air conditioning
Choosing the right air conditioning option requires a detailed analysis. The basis for all considerations is the calculation of the cubic capacity of the room, and the data obtained allows you to indicate the optimal air conditioning option for a given room. This data can be obtained by multiplying the floor area and the height of the room. To calculate the floor area, you will need its length and width, and the product of the values will mean the floor area.
Once you know the cubic capacity of the room, you can consider choosing the optimal air conditioning. Although the cubic capacity is marked first, it is not the only decisive factor that influences the final decision. Factors that should also be taken into account include: the sunlight in the room or the presence of various types of heat-generating devices.
Another important issue is determining the number of people who will be in the air-conditioned room. For the purpose of estimation, it is assumed that each person generates approx. 100-150 W. The data obtained allows for the optimal selection of a device with the right cooling capacity.
Selection of energy efficiency of air conditioning for rooms
Choosing air conditioning that takes into account the energy efficiency of rooms is a process that consists of several stages. To properly conduct the entire procedure, it is necessary to first understand and properly determine three energy efficiency indicators. These are:
- SEER - energy efficiency index in cooling mode, the higher the value, the greater the cooling efficiency, it determines the ratio of the total amount of heat that is removed from the room during the cooling season to the total value of electricity that will be consumed by the air conditioner during the same period;
- COP, which is an indicator of energy efficiency in the so-called heating mode, the higher the value, the greater the efficiency, it is calculated as the ratio of heat delivered to the room to the amount of electricity consumed;
- EER, stands for Energy Efficiency Ratio, but in cooling mode, it is calculated assuming constant temperature (outdoor and indoor); it is calculated as the quotient of cooling capacity and electrical energy consumption.
Knowing the meaning of basic values, you can determine your cooling needs quite precisely. This data allows you to choose the right air conditioner model, adapted to the needs of a given facility or room.
What filters should an office air conditioner have?
Functioning air conditioning in the office is a device that requires proper preparation. For the safety of people staying in the air-conditioned room, it is necessary to use filters so that the air quality in the room is good, does not threaten the health of people staying in the office and does not negatively affect the comfort of work.
Depending on the air conditioning model, different filter variants are used. Most often, devices are equipped with the following solutions:
- pre-filter, also called pre-filter, its role is to eliminate the largest particles, such as animal hair or dust, thanks to which other filters in the device can be used longer;
-
HEPA filter, due to its construction it enables the removal of very small particles of impurities, effectively captures, among others, pollen, mites, mold, as well as viruses and bacteria, its advantage is high efficiency; - carbon filter - its role is to capture gaseous pollutants, a big advantage is that it absorbs odors, should be used in offices with a kitchen;
- an electrostatic filter that uses electrostatic properties to operate, its advantage is that it can be used multiple times, it only needs to be washed appropriately, in accordance with the manufacturer's guidelines;
- a photocatalytic filter whose task is to break down bacteria and chemicals in the air; this process is possible thanks to the properties of UV radiation and the catalyst, ensuring maximum protection and hygiene;
- The antibacterial filter helps prevent the growth of bacteria and mould inside the air conditioning system, making it even easier to take care of the health of your employees;
- ionization filter - its task is to emit ions responsible for neutralizing pollutants in the air, it allows effective protection not only against bacteria and viruses, but also mold, fungi, allergens and smoke.
Air conditioning in an office space should not only improve the comfort of people working in the room during hot weather, it must also effectively take care of the health and well-being of people. This effect can be achieved if the appropriate filters are used in the air conditioning device. Which of the indicated variants is chosen depends to a large extent on the specific conditions and needs of the facility and the size of the room.

What airflow range m/3 should a ceiling air conditioner have?
The ceiling air conditioner should have an appropriate air flow range, because only then will the air circulation in the room be effective enough to improve work comfort. Among the factors that affect flows, the size of the surface and the number of people in the room should be mentioned first and foremost. Specific requirements related to ventilation should also be taken into account.
Experts emphasize that the following values are used when taking into account the size of the office:
- for offices with an area of at least 20 m2 but not larger than 40 m2, the airflow should be in the range of 300 to 600 m3/h;
- in rooms with an area of 40 to 80 m2, the recommended air flow should be from 600 to 1200 m3/h;
- If the area is larger than 80 m2, then the air flow should be no less than 1200-2000 m3/h.
The second issue that needs to be taken into account when choosing commercial air conditioners is that in the case of office rooms, the device should provide 5 to 8 air exchange cycles per hour.
When choosing the right device, many specific features and parameters must be taken into account, which is why professional support from a specialist is a good solution.
Selecting the sound pressure level in the air conditioner
Investing in air conditioning is a great way to ensure comfortable working conditions for employees. A big advantage is that air cooling devices can also perform the opposite function, heating the room in winter. They work effectively, and the costs of purchasing devices tailored to the needs guarantee thermal comfort, which translates into the well-being and quality of work of employees.
Depending on the model, air conditioners have different noise levels during operation. It should be remembered that if the device is to operate in a room where people are present, it must meet the appropriate requirements. The decibel level is given by manufacturers in specific technical requirements. Onninen offers both external and internal units. These are economical and easy-to-use models.
Rotenso ELIS 2.6 kW split outdoor unit air conditioner is a single-phase solution, using R32 as a refrigerant. It provides excellent thermal comfort, and at the same time is an energy-saving model of class A++. Wall air conditioners are mounted directly on the wall, using appropriate brackets.
The interior is designed for units that allow for even air distribution in the room, such as the Rotenso ELIS 2.6 kW wall air conditioner, internal unit . It helps to ensure optimal temperature, and at the same time is a very modern and aesthetic solution. Split air conditioners for the interior are compact and have maximum efficiency.
