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 prevents cold air from penetrating inside, and in summer, hot air. This helps to achieve a comfortable temperature at any time of the year. To achieve this effect, it is necessary to calculate the thermal curtain as accurately as possible. If all calculations turn out to be correct, then you can be confident in the correct choice and high-quality operation of the system.

Calculation of thermal curtain performance

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

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

To select a device, you need to calculate it.

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

Length

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

Power

Power calculations are performed rather subjectively based on the indicators used. The technical characteristics of each model include a clause on the temperature difference between the blown and blown air passing through the device.

Air flow speed

The efficiency of the system’s operation depends on how correctly the air flow speed is calculated. Basically, high-quality work depends on the location of the device, and to be more precise, on the correctly selected height. Incorrect calculation will make it impossible for the system to operate effectively.

Important! It is better if experienced professionals select the air flow speed.

After all the required parameters have been calculated, you can proceed to the next step, namely, selecting the type of system based on the following characteristics:

• Installation type.
• Control method.
• Heat source.

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

How to calculate air and electric thermal curtains

Electricity, air and water are the main sources on which the device operates. The most popular options are air and electric thermal curtains. And it is about them that will be discussed further.

An electric heat curtain is a device powered by electricity. Most often it 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.

Thermal air curtains are used mainly to divide the space of the room being used.This system does not have heating elements that are built into other types of systems. Their work is based on the rotation of large fans. The air flows created by the blades help to divide the space into temperature zones. Most often used in warehouses or industrial premises.

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

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

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

Power calculation formula

To calculate the power of the unit, you should use the following formula:

VxTxK

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

T is the difference between the air temperatures outside and inside the room. The second indicator is selected based on what temperature in the room needs to be set;

K – air dispersion coefficient. Depends on the insulation of the room, and the higher 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.
