“…Nevertheless, pitting corrosion occurrence at high regeneration temperature greatly restricts the application of anodized aluminum plate regenerator. Therefore, more investigation on the mechanism and improvement of pitting corrosion, surface treatment technologies and also evaluation of possibility to use the new thermo-acoustic techniques in the refrigeration field [29] are necessary in the future work. …”

Abstract:The traditional vapor compression cooling system (VCS) has been criticized for its heavy reliance on electricity consumption and limited control ability of humidity. Compared with the VCS, the liquid desiccant cooling system (LDCS) is more efficient by handling the sensible and latent load separately. The present study investigated the regeneration and corrosion characteristics of an anodized aluminum plate regenerator for the first time. Comparative tests were conducted to present the regeneration and corrosion characteristics of the normal and anodized regenerator. The influence of internal heating on the regeneration performance was also identified. The results showed that the corrosion rate was reduced from 0.0005218 mm/year for normal aluminum to 0.000011 m/year for anodized one under the same operating conditions. However, pitting corrosion was observed at operating conditions with high solution temperature, as the anodized layer of anodized aluminum was damaged due to the high temperature. Compared with the normal aluminum regenerator, the anodized one had an average enhancement of 24% and 23.7% in terms of regeneration rate and effectiveness, respectively. It was attributed to the increment of surface energy from 26.4 mN/m for normal aluminum to 47.6 mN/m for anodized plate. Besides, it was found that, compared with adiabatic one, the internally-heated regenerator improved the regeneration rate by 6.0%~38% and the regeneration effectiveness by 6.3%~32% depending on the operating conditions. The advantage of present study is that it can guide the design of anodized aluminum regenerator for LDCS.

The term "Smart" in the last decade has often flanked other words to express a new and intelligent way of living in a modern society where you cannot separate the two synergic aspects: Energy and Sustainability. These latter two aspects flow into the new way of managing an isolated territory that often presents difficulties because of no interactions with the surrounding area; to remedy these difficulties has been developed in recent years the "Smart-Island" project, which involves many European countries and several sponsors. The concept of "SmartIsland" defines a way of life in an isolated environment, such as that of these islands, can solve independently, with the use of renewable and sustainable sources the energy needs of the island, with some projects that take into account the preservation and the wealth of the territory. In this paper, after a brief review of what has been proposed in some islands of the world, it will develop a case study, represented by the island of Favignana, which has particular characteristics in relation to its energy dependence.

In hospitals, the energy demand of the different areas can be divided in form of thermal energy, cooling and electricity. The complexity of the energy system of each structure may be different from hospital to hospital as well as to the volume of manufactured. In fact, the energy demand is closely related to:-health activities that take place in it; -its geographical location; -the structural type and adopted plant The use of different type of energy sources is due to the implementation of different technology options and then to specific operating costs and levels of different issues.In the graphs below (Figure 1 and 2) is shown the values and percentages of annual energy demand required for two different hospitals located in the northern of Italy, respectively: Zucchi Clinic (MB) and the City of Pavia Care Institute (PV) -Reference year 2012.The energy demand for Heating, Ventilation and Air Conditioning (HVAC) is equal to 45% for the first structure and of 69% for the second structure analyzed.It denotes in both cases, that this request always results in a higher percentage than all other requests and in the case of the care institute City of Pavia, the contribution percentage is higher of 50% higher.Taking into consideration the same study, conducted for the Zucchi clinic and the City of Pavia health institution, also ensures that the demand for natural gas (methane gas) for technological uses is particularly relevant to the request for HVAC uses, and then for technological uses. In fact, the following charts (Figure 3 and 4) show that the demand for natural gas is higher in the winter months with a INTERNATIONAL JOURNAL OF HEAT AND TECHNOLOGY ABSTRACTIn hospital, air conditioning and air treatment systems are of great importance both for functional and energetic point of view. In fact, these systems must guarantee the conditions of hygrothermal air quality and comfort for people (patients, staff, visitors), but also meet the operational requirements related to the medical activities in specific environments or departments. In particular, diagnosis and surgical activities request to ensure a high air quality conditions in order to ensure the appropriate environments of asepsis and hygiene [1][2][3]. The aim of this study is to evaluate the possible energy saving solutions to optimize and reduce energy demand [4][5] in the health facilities. Particular attention is focused to the operating theaters, which, because of the type of technological systems used, have a major impact on energy demand the entire healthcare facility.
