Wineries present significant interest on a research level, combining Indoor Air Quality (IAQ) issues related with substances emitted through the wine production, as well as the need for minimizing conventional energy consumption (optimizing energy performance). In the proposed work, experimental and theoretical analyses are presented which aim to achieve both targets, that of improved indoor climate and energy performance. An extensive measurement campaign was implemented, regarding indoor climate thermal parameters, as well as concentration of substances (CO2, VOCs, NO2) affecting IAQ. The results of the parameters were exploited for the assessment of indoor climate; moreover, data from indoor thermal parameters together with values of specific parameters related to the efficiency of the individual devices were utilized in the development of the energy model. The model was used to formulate and evaluate proposals for reducing the energy consumption of the winery. The proposals include the use of Renewable Energy Sources (RES) and, in particular, the installation of a photovoltaic array on the roof of the premises. Finally, an economic and technical study was carried out to determine the performance of the suggested interventions and the expected payback period.

Investigation of thermal comfort in various types of buildings is a rather intense research activity by recent years. Besides thermal comfort, the Indoor Air Quality (IAQ) is also important for the sensation of humans in indoor environments, as well as for their health. In the proposed work, a systematic measurement campaign in university classrooms in the Educational School of the University of Western Macedonia, Florina, Greece, is presented; the campaign was performed through winter time, noting that the University lies on the coldest thermal zone on a country level. Measurements include thermal comfort parameters, as well as IAQ ones, namely volatile organic compounds (VOCs), aldehydes and NO2concentration.As far as thermal comfort is concerned, Fanger's thermal comfort indices are calculated, on the basis of the measured data; a comparison is made through the support of questionnaires investigating the actual thermal comfort level of the students while being in the classrooms, aiming at providing information on an adaptive sensation level. In terms of air quality, measurements are made both indoors and outdoors, allowing the determination of indoor/outdoor correlations.

The proposed work attempts to examine whether district cooling is a sustainable solution for cooling applications in a modern urban area where there is already a district heating system network installed. In order to make a complete and objective assessment about the aforementioned topic, the majority of factors affected by or affecting such a project is taken into consideration, namely energy, environmental, socio-political or financial issues. The analysis uses as reference system that of the district heating of the city of Kozani, Northern Greece, operating since 1993; the system uses heat produced by the nearby coal power plants. In conclusion, district cooling is assessed as a feasible and sustainable choice for Kozani with multiple benefits for the region. For example, the increase of the pipeline network lifespan by minimizing corrosion due to oxidization, the extended utilization of waste heat, the reduction of the load on the electric power network as more and more customers will shift from air-conditioners to District Cooling and the creation of a variety of either short term or long term jobs during the construction phase and during the lifetime of the installation. Moreover, a variety of suggestions is given for prospective researchers on the topic as well as proposals on the development of the project further than the pilot phase.

The achievement of thermal comfort conditions and acceptable air quality throughout reasonable energy consumption level, constitute critical issues for the operation of a sports center. Focusing on indoor aquatic centers, the problem is more intense, considering the evaporation rate of the swimming pool, its thermal needs, as well as the concentration on indoor air of substances used for water cleaning. Ventilation is of high importance for the achievement of acceptable indoor air quality; permitted by the outdoor humidity level, it may lead to accepted levels of indoor relative humidity, also contributing to energy saving. In this work, the air exchange rate of an indoor aquatic center is studied on an experimental basis. The actual air exchange rate during non operation and operation hours is determined according to the tracer gas decay and equilibrium analysis methods respectively; the air exchange rate was proven to be insufficient, given the international standard values. The discussion included limitations related to the implementation of the methods in large spaces as the studied one. Solutions for enabling adequate ventilation levels at the aquatic center are investigated through simulation analysis. The COMIS software is used for the calculations; the results demonstrate the need for implementing forced ventilation.

Air quality and comfort parameters in a naturally ventilated aquatic centre were studied in relation to the outdoor pollution levels. Simultaneous measurements of PM 2.5, as well as of volatile organic compounds, were carried out for the indoor and outdoor environment of the aquatic centre. The chemical analysis of ionic species and trace elements associated with particulate matter was also performed. In addition, automated analyzer for NO2 and O3 was used in order to record the indoor and outdoor levels of these pollutants. Analysis of diurnal variation of the pollutants’ concentration was applied to the collected data, allowing the identification of potential variation on the sources affecting the indoor air quality. PM 2.5 concentration was almost two times higher indoors than outdoors with average values of 13.96 and 6.78 μg/m3, respectively. Concerning the ion fraction of PM 2.5, SO42− and Ca2+ were the ions with higher concentration indoors with values of 1.06 and 0.93 μg/m3, respectively, while the percentage of Cl− to the PM 2.5 fraction of the indoor atmosphere (9%) was too high than outdoor ones (1%). These results showed that indoor air of swimming pool concerning PM 2.5 and ionic species is mainly affected by the chlorination process along with the comfort conditions (high relative humidity) created during the operation of the facility. The common volatile organic compound concentrations at indoor air are generally in higher levels, compared to the outdoor air with p,m-xylene and toluene to be the substances with the higher concentration for indoor and outdoor area, respectively (7.80 and 1.57 μg/m3); nevertheless, values were rather low compared with the findings of other studies. Also, they clearly demonstrate a diurnal variation as a result of poor ventilation during night. As it was expected, chloroform showed the highest concentration compared to the other volatile organic compounds with values ranging from 3.35 to 135.89 μg/m3, with an average of 54.50 μg/m3. Concerning the NO2 concentration, indoor levels showed an increased pattern when the swimming pool was fully occupied, a fact that reveals a possible correlation. As an overall conclusion, the natural ventilation and the disinfection process seem to play a key role to the air quality of the indoor air of the aquatic centre.

This work presents the study of two innovative solar water heating systems, integrated on the facades and the roof of a social house building. One of the systems combines collector and storage tank in a single unit, called Integrated Collector Storage solar water heater; the other one comprises a photovoltaic and a thermal collector known as Hybrid Photovoltaic/Thermal device, in which the produced energy support both thermal and electrical needs. The analysis has considered the integration of the studied solar systems on building's envelope, investigating the effect of these systems in terms of building's thermal load along with their capacity to cover the hot water and electrical needs. The energy behavior of the building, as well as the energy output of the solar systems are investigated through simulation analysis for two cities (Nicosia, Cyprus and Athens, Greece) and three orientation modes (South, East and West). The results show that, after the interventions, the energy demands of the building for space heating and cooling are decreased at about 10%, while the hot water and electrical demands are covered up to 80 and 50%, respectively. The energy contribution of the respective solar systems with regard to the buildings’ energy demand is evaluated through Life Cycle Assessment; the respective analysis allows the evaluation of the environmental impacts during the entire life cycle of the considered systems.

The use of heat pump systems in applications like the production of hot water or space heating makes important the modelling of the processes for the evaluation of the performance of existing systems, as well as for design purposes. The proposed semi-analytical model offers the opportunity to estimate the performance of a heat pump system producing hot water, without using detailed geometrical or any performance data. This is important, as for many commercial systems the type and characteristics of the involved subcomponents can hardly be detected, thus not allowing the implementation of more analytical approaches or the exploitation of the manufacturers’ catalogue performance data. The analysis copes with the issues related with the development of the models of the subcomponents involved in the studied system. Issues not discussed thoroughly in the existing literature, as the refrigerant mass inventory in the case an accumulator is present, are examined effectively.

The rapid progression in the use of heat pumps, due to the decrease in the equipment cost, together with the favourable economics of the consumed electrical energy, has been combined with the wide dissemination of air-to-water heat pumps (AWHPs) in the residential sector. The entrance of the respective systems in the commercial sector has made important the modelling of the processes. In this work, the suitability of artificial neural networks (ANN) in the modelling of AWHPs is investigated. The ambient air temperature in the evaporator inlet and the water temperature in the condenser inlet have been selected as the input variables; energy performance indices and quantities characterising the operation of the system have been selected as output variables. The results verify that the, easy-to-implement, trained ANN can represent an effective tool for the prediction of the AWHP performance in various operation conditions and the parametrical investigation of their behaviour.

The operation of desiccant air-conditioning systems is characterised by processes implemented to the moist air of the environment; it is, thus, expected to be affected by ambient conditions. The present work aims at quantifying this influence on the basis of an easy-to-implement, steady-state model of the system, presenting an efficiency factors approach, which has been experimentally validated. The analysis examines the behaviour of the ventilation and the recirculation cycles, which constitute the marginal cases regarding the achieved values of the outside air fraction, given the ambient conditions, the desired regeneration temperature and the efficiency of the involved components. The fact of a desiccant cycle undergoing a set of changing ambient conditions by its actual operation is also considered in the analysis. The results provide useful information for the selection of the optimum configuration to the designer of a desiccant air-conditioning system.

The use of a heat pump as an auxiliary energy source for solar domestic hot water systems can achieve significant energy savings, due to the remarkable potential of heat pumps on the efficient provision of thermal energy. In this work, the performance of a combined solar thermal heat pump hot water system is investigated. A component based simulation model for the whole system was experimentally validated. Emphasis was paid on the formulation of a simple and efficient approach for the modeling of the heat-pump. The performance of the system on an annual basis is investigated, with regard to the methodology used in solar domestic hot water systems testing. According to the results of the analysis, the system achieves significant auxiliary energy savings, which can present a value in the order of 70% for the climatic data of Athens. The temperature set-point for the activation of the heat pump proves to be an important parameter for the performance of the system, noting that the higher the value of the set-point, the lower the efficiency of the heat pump.

The information related to the amount of vapour in the air, can be of critical importance for various processes, such as air-conditioning in buildings, drying or material processing. This information can be provided through different quantities such as the absolute humidity, relative humidity, dew-point temperature or wet-bulb temperature. Quite often, the user is more interested in a secondary quantity, which can be obtained through the use of appropriate relations or charts, rather than the directly measured one. The present work aims at proposing a methodology for the estimation of uncertainty related to the indirect humidity measurements. The analysis concentrates on the usual case which refers to the calculation of the values of derivative quantities, such as relative humidity or the amount of vapour in the air, through the direct measurement of quantities, such as dry-bulb temperature and dew-point temperature. The estimation of uncertainties is based on the propagation of probability distributions which could describe the available state-of-knowledge of the directly measured quantities, through the implementation of the Monte-Carlo simulation, which is consistent with the nonlinear characteristics of the hygrometric equations.

Solid desiccant air-conditioning systems can take care of both the sensible and latent load of a conditioned space, as well as of the fresh air requirements, through the use of thermal energy. The development of desiccant systems, competitive to conventional cooling ones, would require the optimization of the parameters which are involved in the design of the systems for a range of ambient conditions the systems will face throughout their lifetime. The present work aims at identifying the main design parameters, and investigates their effect on the performance of the systems. Specific guidelines for the dimensioning of the systems are proposed, on the basis of an easy to implement steady state model.
