Abstract

Purpose

The purpose of this paper is to describe and categorize calculation methods for conducting a complete air conditioning study. More specifically, this paper is a general review of cooling loads calculation methods, psychrometric calculations for installing a central air conditioning unit, ways of fan coil units connection and air duct calculation methods.

Design/methodology/approach

This paper was based on two pillars: a dissertation for an industrial facility and technical information found after methodical research.

Findings

After a brief reference of the calculation methods and the air conditioning systems installed in this industrial facility, this paper concludes with the most appropriate calculation methods for this industrial facility.

Research limitations/implications

This study describes some calculation methods. Thus, future research could be addressed toward the analysis of more methods.

Practical implications

This paper includes implications for choosing the most appropriate calculation method according to the air conditioning system installed.

Originality/value

The originality of this paper lies in the fact that, except for the theoretical part, there are some examples taken from a case study, thus it can be used as a future guide for selecting methods and systems of industrial air conditioning.

Abstract

Purpose

The purpose of this paper is to stimulate interest in the use of quality management methods and tools and to provide a basis and direction for further improvement in the global brewing industry.

Design/methodology/approach

The methodology that is followed in the paper is based on the study of quality management tools and best practices in global brewing companies.

Findings

From all evidence found by this research, the conclusion is that quality management can dramatically improve certain operations and reduce cost or increase profit as well. All of the global brewing companies examined in this paper have their quality policies and each one of them uses what fits best to its business profile.

Research limitations/implications

This study refers to some of the largest brewing companies in the world. Future research could be addressed toward the analysis of other smaller brewing companies, which are characterized by the concepts of quality management.

Practical implications

The analysis of quality management in the global brewing industry may cause the interest of other brewing companies and other stakeholders affected by this industry. Quality tools can be very useful for dealing with problems and improving procedures in a brewery. Furthermore, the extension of this work with detailed references to these tools could produce a quality guide for brewing companies.

Originality/value

The value of this paper lies in the identification and presentation of tools and quality policies which have been successfully developed by global brewing companies and may as well be implemented by others.
