Calculation of the thermal curtain

The thermal curtain is a certain barrier to the air flow that comes from the street. In winter, the curtain does not allow cold air to penetrate, and in summer - hot. This helps to achieve a comfortable temperature at any time of the year. To achieve such an effect, it is necessary to calculate the thermal curtain as accurately as possible. If all the calculations turn out to be correct, then you can be sure of the correct choice and quality work of the system.

Calculation of the performance of the thermal curtain

Most often, systems are found where a large number of people are located. Usually these are cafes, restaurants, shopping centers, industrial premises, warehouses, educational buildings.

Reference! This heating system is needed to ensure a constant temperature in the room.

To select a device, it is necessary to carry out its calculation.

In the process of calculation, parameters such as dyne, power and air flow rate are considered.

Length

To choose the most optimal length, it is very important to consider the dimensions of the doorway. The main dimensions are indicators of the width and height of the opening. The closer the curtain is to the door, the higher the efficiency of its operation will be.

Power

Calculation of power is performed, rather, subjectively based on the indicators used. The technical characteristics of each model include a paragraph on the difference in temperature of the blown and blown air passing through the device.

Air flow rate

From how correctly the calculation of the air flow rate will be made, we can talk about the efficiency of the system. Basically, quality work depends on the location of the device, and to be more precise, on the right height. Incorrect calculation will lead to the impossibility of effective operation of the system.

Important! It is better if experienced professionals engage in the selection of air flow rates.

After all the required parameters are calculated, you can proceed to the next step, namely, the selection of the type of system, proceed from the following characteristics:

  • Type of installation.
  • Management method.
  • Heat source.

In order for the curtain to serve for a long time and with high quality, it is necessary that all calculations are carried out correctly.

How to calculate the air and electric thermal curtain

Electricity, air and water are the main sources on the basis of which the device operates. The most popular options are air and electric thermal curtains. And it is about them that we will discuss later.

The electric thermal curtain is a device that is powered by the mains. Most often can be found in industrial and domestic premises. It differs in that it has several power switching modes. In the summer, the device can be used to supply cool air flow.

Air curtains are mainly used to divide the space of the room used. There are no heating elements in this system that are built into other types of systems. Their work is based on the rotation of large fans. The air currents created by the blades contribute to the division of space into temperature zones. Most often used in warehouses or industrial premises.

Since the above types are subspecies of this thermal system, the calculation and further selection is carried out according to the same parameters:

  • length, which is calculated based on the dimensions of the doorway;
  • device power;
  • air flow rate.

And if the first two parameters are mainly important for calculating the electric curtain, the latter is a very important indicator when calculating the air curtain.

Power calculation formula

To calculate the power of the unit, it is worth using the following formula:

VxTxK

Where V is the calculated volume of the room in cubic meters;

T is the difference between outdoor and indoor air temperatures. The second indicator is selected based on what temperature in the room must be set;

K is the coefficient of air dispersion. It depends on the insulation of the room, and the greater its indicator, the better the insulation.

Calculating the performance of a thermal curtain is not so difficult, and you can make all the necessary calculations yourself.
