Analysis and measures for energy savings in operating theaters

Abstract

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.

Monitoring of the indoor microclimate in hospital environments a case study the Papardo hospital in Messina

“…This proceeding, followed by a lot of country, is able to development and use new technologies "e-sensing" to monitoring the hospitals field, [12][13][14][15]: for the detection of main pollutants [16][17][18][19][20][21][22][23][24], in museums, to study the possible causes of deterioration of works of art, [25][26][27], allows you to joint either all monitoring parameters and avoid the risk to overcome limits of these parameters.…”
