Heat ventilation computer

Heat of ventilation - calculator

Heat necessary to give the air introduced to heat a room. Dispersions calculable in various units of measurement

The calculation of ventilation heat is a critical aspect in thermal engineering and in the design of heating and ventilation systems. Understanding and calculating ventilation heat is critical to ensuring thermal comfort and energy efficiency in buildings and a wide range of industrial applications.

Heating a room requires a specific amount of thermal energy, which can vary considerably based on factors such as the size of the room, the external climatic conditions and those that you want to give to the internal environment. Accurate calculation of ventilation heat is essential to correctly size systems, determine heating requirements, and optimize energy consumption.

This program was developed by Itieffe with the aim of providing users with a comprehensive understanding of the basic concepts and methodologies needed to calculate this heat in different contexts. We will explore the fundamental theoretical aspects, formulas and practical tools used in thermal engineering. Furthermore, we will learn how to consider the specific variables of each case, such as the outside temperature and the amount of air needed.

Mastery of this calculation is not only essential for professionals, but can also be an added value for architects, civil engineers, and anyone involved in the design and management of interior environments. An accurate calculation of the necessary heat will contribute to people's well-being, environmental sustainability and the reduction of energy costs.

Through this program, we will guide you step by step in learning this crucial skill and provide you with the knowledge and tools needed to successfully tackle calculations in various contexts.

Instructions

Let's see how to calculate the heat that needs to be supplied to the air to heat an environment:

first we begin to enter the values necessary for the calculation:

we enter the required temperature in the room 21.5 ° C,

the external temperature -5 ° C (we can also see alongside those of the project in Italy),

the temperature leaving the terminal 38 ° C (grill, vent, anemostat, air heater, etc.),

the dispersion of the environment in the unit of measurement chosen from: kW - kcal / h - kJ - BTU (in this case the kW are set).

The dispersions must be calculated separately. You can use the program: heat requirement present on this site for a rough indication.

Let's analyze the results:

the air necessary to transmit the heat needed to have 21.5 ° C inside, is 5.212 mc / h, while the energy required is equal to 76.6 kW.

The values expressed in the other units of measurement are also shown as an indication (keep in mind that the dispersions have been calculated in kW, adjust accordingly).

Easy right?
