This report shows the study performed at Taipei National University of Technology in Taipei to evaluate the performance of a solar air conditioning system. The performance is evaluated under Taiwan climate conditions. The research is performed under summer weather conditions. No influence is done on these conditions. A solar air conditioning system currently available on the market is used. No changes are made to the system. The work to be done is divided into different phases in order to guide the process. First, a literature research is done to find similar research done on this topic and to gain a basic understanding of the topic. Then several measurement plans are made to investigate different parts of the system.. Measurements are done. It is tried to developing a computer model in order to be able to simulate the system performance. The overall objective was to gain knowledge about a solar assisted air-conditioning system and develop a model to simulate the system. Initially a list of research questions was made in order to quantify ‘gaining knowledge’ about the system. The plan was to answer them by using measurement data and creating a model to perform simulations. There are measurements done in this report, however due to too many ‘unknowns’* it is difficult to draw conclusions from them. A lot of research questions are still open and they are also not included in this report. It is also not succeeded to make a working model of a solar assisted air conditioner. It is succeeded in making a model to predict the performance of the evaporator. This model is currently within 11% accurate.

The object of the thesis is to design a grate boiler for bagasse and brown coal combustion with a heat output of 160 MW. Calculations of a flue gas stoichiometry are based on known element analyses of each fuel. The crucial part of the thesis includes designs of heat-exchanging surfaces, where the bagasse is considered as the main fuel while the brown coal is the spare one. Overall thermal balance and an actual boiler efficiencies are provided in last chapters. The boiler-outlet flue gas temperature is compared with the dew point temperature at the very end of the thesis. As a part of the thesis there is a design of the boiler attached.

This thesis deals with a project of steam boiler to combustion of refused-derived fuel. Considering the required fuel and output parameters of the steam was made the thermal calculation of boiler with it design and an individual calculation of heat exchange surfaces; hydrodynamic and aerodynamic calculations of the steam boiler.

This master's thesis deals with design of steam grade boiler for burning refuse derived fuel with power output of 70 t/h. The assignment contain a requiered steam output parameters and composition of fuel. From this composition of fuel is calculated stoichiometric calculation, the heat loss and the efficiency of boiler. After that follows a design of the boiler with closer design of each of the heating surfaces.

The diploma thesis deals with the design of cooling devices of a fourteen-storey polyfunctional building with administration part and housing units. The thesis describes the physical nature of cooling, the basic types and functions of cooling systems and legislation related to cooling devices. Two types of cooling systems are selected and developed for the assigned object at the building permit design level. The work includes calculations of all elements of individual systems. The purpose of this diploma thesis is the comparison of these variants and the evaluation of suitability for use on the individual parts of the assigned building. The variant chosen is elaborated at the level of the rea-lization project, including the drawing documentation.

For set parameters of a steam and a boiler feed water is designed a thermal and dimensional plan of the boiler, allowing high efficient requests. A boiler is used for combustion of blast furnace gas contains 10% of a natural gas used as a stabilisation element.

This thesis deals with the change of the fuel base of a coal boiler due to the reduction of CO2 emissions and its thermal recalculation. In the first part, there is implemented calculation of the combusting chamber. This is followed by the recalculation of the heat transfer surfaces. The emphasis is placed on the preservation of the exsiting steam parametrs.

This diploma thesis deals with a design of a boiler for stillage combustion. Stoichiometric calculations and enthalpies of combustion gases have been calculated from the specified parameters. In addition, heat calculation, design of the combustion chamber dimensions and dimensioning of heat surfaces were accomplished. The boiler has an evaporator with natural circulation and a fire grate.

An objective of this thesis is to design a grate steam boiler for burning straw. Generated steam will be used for technological purposes or cogeneration. Calculations of the heat comes from engaged temperature and pressure of the overheated steam and characteristics of characteristics of the biomass as well.

The purpose of this Diploma Thesis is the construction design of the steam-boiler for the combustion of biomass – wood pellets. For the specified parameters have been defined stoichiometric calculations and calculations enthalpy burnt gas. In sequence, there is designed and solved the configuraion of the steam-boiler, so that the result design and the number of the heat-delivery surfaces can be determined, in dependence on the required inlet parametres of the air and outlet parametresof the water vapour. These parametres mean the amount, the temparature and the pressure. The aim of the thesis is to make a design of the steam.boiler burning biomass according to the set parametres. This very ecological fuel can really substitute the fossil fuel and friendly respect the environment.
