Installation, starting and adjustment of ventilation and air conditioning systems A Guide

Many people believe that the main motivation In any professional field is earning money and promotion at work. On the one hand, these are really the main Motives for people to work every day ( sometimes through force) why people go to work every day (not always the favourite one). However, we can find many people Who are unassuming and work for lower fee being completely satisfied with their job works for less salary because they are beloved with their job. So what motivates a ventilation engineer to work in this sphere?

American psychologist Abraham Maslow has identified deep motives common to all people that determine human behavior.The psychologist believed that physical survival is the first deep motive and basic human need. After he is satisfied, the person will switch to the next need. As soon as it is completed, it is the turn of the next one, there are only five main motives:

These include air, food, drink, shelter, clothing, warm, sleep – everything that is necessary for human survival. Maslow included sex in the same group. The psychologist considered these needs to be the most important – in a situation of extreme need, a person, first of all, will think about how to survive, that is, about physiological needs. Until they are satisfied, it is unlikely that he will have other desires.

As soon as the physiological needs of a person are satisfied, the desire for security and confidence in the future come to the fore. People want to control their lives, see order and predictability around them. In society, this means the absence of direct threats to life and health, protection from natural disasters, social stability, financial security, and so on. The police, rescue services, medical and municipal institutions in general close these needs of people in society.

Initially, Maslow called them "the need for love." He believed that after satisfying physiological needs and obtaining security, a person expects love and affection from other people. This block of the pyramid includes social relations: family and relatives relationship, friendship, a sense of trust in others and acceptance of a person by others.

Maslow divided these needs into two types: self-esteem (self-esteem, personal achievements, independence from others) and to be respected by others. A person wants to feel important both in his own eyes and in the eyes of other people. Self-esteem is directly related to a sense of self-confidence and self-worth, with self-acceptance and self-worth. Respect from others is associated with the desire to be approved by others, successful and appreciated.

Maslow considers, that self – actualization is the ability of a person to do what he was created for. A musician feels the need to make music, an artist – to draw, a poet – to write. If a person wants to be happy, he must do what he was born for. This desire to develop one's potential is the highest need in Maslow's hierarchy. At the same time, the psychologist notes that the specific behavior into which this need will develop varies from person to person. For one, this will be expressed in the desire to become an ideal parent, for another it will be associated with sporting achievements, for a third it will be a joy to create or invent.

To begin with, let's consider how much money you can earn constructing doing ventilation. That means we start from first stage.

Prices are given for September 2023.

HVAC repair costs will differ depending on the type of unit and how extensive the repair is. Here are some average service prices based on your HVAC unit:

If a component of your HVAC is starting to fail, you’ll need a replacement. HVAC companies will happily inspect your system and provide you with a quote for a part replacement. Here’s what you can expect:

From this table we can conclude that, any mater on Ventilation, can rise to the first step of the pyramid quite adequately. To master the remaining steps, we need to know the material outlined in the following chapters.

1. Name the five steps in the hierarchical model of human needs according to the theory of Abraham Maslow.

2. Evaluate the implementation of this model on the example of work in the field of installation of ventilation systems.

3. Give an example of self-actualization in your current profession.

4. Count the advantages of the profession of an installer of ventilation systems over other professions basing on of the above model.

5. Give a comparative analysis of prices (for example, the installation of fans) from several sources on the Internet. Formulate the cost structure of the service as you see it.

The state of the air is characterized by its main parameters: temperature, relative humidity, mobility (speed).
