Things To Consider While Recruiting

If you are running a company, you really need experts to get it to a good level. Here are some tips for you on recruitment.

While calling for applications

Most people only think about the selection process, but the most important thing while recruiting is calling for applications. You need to decide what kind of people do you want for the job and set the criteria accordingly. For that, you should assess the job first. Determine whether the job is more technical or more managerial, or something else. Based on this, you can figure out the minimum qualification for the candidates. Also consider the level of the job. If it is higher up the ladder, you would need someone mature and experienced. Similarly, you do not need someone with a lot of experience at the beginner level. You need to figure out some other details in the same way. 

This is important because it tells the candidates whether they should apply or not. The selection process can never go right if you do not handle this step properly. If invitation for applications is not descriptive enough, you will get too many applications, most of which will be a waste of your time. And if it is too specific, you might lose some really great candidates. So, be very careful and reconsider everything before finalizing.

During the selection process

After sorting through all the applications, you get to the selection process where you can finally find the right person for the job. Different recruiters consider different things. Here are some good ideas for you.

1. Personality: An employee doesn’t just need to be able to do his/her own work. They should also be able to work well with others. So, the recruit should be friendly and easy to work with. Although these things can only be tested with time, but if you want quick results you can try an EQ test. It is emotional quotient. It tells you how a person handles and expresses emotions. We are not just talking about happiness, sadness, hatred and other soap opera emotions. Other emotions like fear, stress, pride, etc, are also tested.

2. Confidence: It is one of the most important qualities you need in a person who is going to deal directly with the clients. Even if the recruit will be working mostly on the backend, he/she needs to be confident about their plan to complete any task. Only then you will be able to get the job done.

3. Skill set: Qualification and other trainings tell you only a little fraction of a person’s skills. While some of the people are only as skilled as it says in their CV, but others have a lot more to offer.

An Overview Of Refrigerants

Air conditioners are a must have in modern times, both for comfort and also as a sign of status in the society. So why don’t you get some basic knowledge about the most important thing regarding the air conditioners? 

Refrigerants – what you should know?

Yes, you are right. It is the refrigerant which is a mixture, especially a fluid. This is used in the heat pumps and in the refrigeration cycle. It has to pass some of the phase transitions which transform the liquid to a gas and the reverse too. Numerous working fluids are used for this purpose. The compounds of fluorocarbons or chlorofluorocarbons were commonly used in the twentieth century. But now they are not in use due to the depletion effects of ozone. The compounds of ammonia, sulfur dioxide and some of the hydrocarbons like propane are used now in the refrigerants. In fact, in the various continents the refrigerant handling license is provided after certain degrees.

The refrigerant ideally has all the thermodynamic properties. These properties should have a boiling point, a high heat of vaporization, a moderate density in the form of liquid and a high critical temperature. The boiling point and the density of the gas are generally affected by the pressure. They will be non-corrosive to the components which are mechanical and they should be free from the toxicity as well as flammability. The refrigerants should never cause the depletion of ozone and bring change in the climate. To get a refrigerant handling licence, you need to have the basic knowledge of refrigerants.

These refrigerants are non-flammable and non-toxic. Their stability as well as their potential for global warming and ozone depletion has increased the concern of their random usage. The Bromo chlorofluorocarbon, CFC and HCFC are the potentials of ozone depletion. But PFC is not potential, it is non-ozone potential. The new refrigerants, which are getting prepared in the twenty -first century do not cause any harm to the environment. They are safer for the healthy atmosphere and pollution will be lessened. Their applications have been held up for the concerns regarding the factors of toxicity as well as flammability.

Refrigerants are used widely in technologies

These refrigerants are used in the systems of air conditioning in buildings, sports, various industries, automotive as well as food industries (which include the food production, storage, and retailing too). After the removal of the refrigerants they are recycled for cleaning up of the contaminants and they are transformed into the previous condition. Some of the refrigerants can be even dangerous after the recycling process is done.

To pursue a course or training course on refrigerants, you should choose the right place.
