CHAPTER: MATERIAL AND METHOD

It is important to define a working method in order to ensure a good result. In this section, the steps of the working process are explained sequentially.

Gathering of facts

An analysis of the system is necessary before studying anything related to the topic in order to get both broad and detailed information. It is necessary to do research to find out how these systems work and what type of technology and fuels are used, which may depend on the country where it is located. The information has been found in science articles, printed books and internet websites. However, the principal source of information has been internet because it is easily available and data are usually updated. The design of a trigeneration system is a complex problem.

It is difficult to make an economic optimisation of it because a lot of factors are involved in it. The design process is based on the analysis of different reasonable techno economic alternatives where it is necessary to make decisions. The demands of residential and service sectors are characterized by temporal variations, making the design process even more difficult. The energy demand of buildings has the following characteristics:

Consumption of several types of energy (electricity, heat, cold,…) to meet the different services (heating, cooling, hot water, lighting, electrical appliances, computes,…).

The demand of some services (heating and cooling) is concentrated in some months of the year.

The temporal variation of the demand is significant due to environmental factors and occupancy.

The design process can be structured in the subsequent way. Firstly, a study of the adequate type of technologies may be carried out. Next, the required power of the equipments must be determined. Once the system configuration is decided, it necessary to establish the operating procedure for each installation for every period of the year.

Gathering of data

The analysis of a system involves a number of factors and requires a great amount of input data which make it possible to evaluate and make decisions. First of all, it is necessary to have useful information about the demands which the system will have placed upon it. The demands can be obtained from different sources; however it is a hard task to find them because it is not usual to register the energy consumption of buildings. Therefore, different sources of information have been used in order to characterize the various demands of the building considered. In the section Input data the information as to where each demand has been obtained, will be ...
