Bassano del Grappa, December 2016: The reorganization plan of the Apulian hospital network has been approved earlier this year. The idea was developed to adapt the healthcare delivery in the region to the new standards established by national legislation. This is not aimed at cutting the number of beds, but rather to reorganize the existing structures, streamlining small regional centers and especially by strengthening the main hub. Among these is the University Hospitals of Foggia, the second largest hospital of Puglia.

With the reorganization plan in mind, this facility aims to achieve the ambitious goal of a hospital of "Excellence", understood as a health facility where there all the functions of modern medicine are present. To achieve this goal work is underway to build a new emergency-urgent complex. The structure, which will be completed by the spring of next year, will host First Aid, Emergency Surgery, CICU (cardiac intensive care unit), Intensive Care, Stroke Unit, a total of 250 beds.

In health-care structures, air conditioning systems must not only guarantee the well-being of patients, but also meet the needs of the processes related to medical activities, such as operating rooms. The operating department represents one of the most technologically advanced nuclei within the hospital. The environmental parameters on which the system must be constantly monitored are; the temperature, the relative humidity, the degree of contamination of the air, and the supply air speed. For these reasons, the air conditioning system is, especially in newly constructed buildings, a real auxiliary system for medical activity, thus it assumes paramount importance.

The new complex of the Hospitals of Foggia was therefore fitted with an air conditioning system based on 5 Climaveneta chillers and heat pumps with high efficiency, combined with 31 WIZARD air handling units.
In more detail, there are; 1 multi-purpose heat pump ERACS-Q / SL-CA 3222, 1 reversible heat pump FOCS-N / SL-4822 and 3 liquid refrigerant FOCS2 / SL-CA-E 4822. All the units are air-cooled, in the super silent version of class A, with considerable total cooling and heating capacity: 3183 kW for cooling and 1909 kW for heating. Hospital HVAC systems should always be slightly oversized, first to ensure continuous operation in case of failure or maintenance of a unit, because when it comes to hospitals, and second because hospitals are often characterized by continuous evolution, linked to the development of medical technology, the possible changes in user requirements, and also possible future expansions. Furthermore, as hospitals hold continuous operations every day and throughout the year, the air conditioning unit must be convenient to access and easy to maintain, thus minimizing interference with medical activities. The reliability of Climaveneta units, their flexible operation, the multi-purpose units’ ability to simultaneously satisfy the cold and hot demand requirements without implementing any operating mode settings, the possibility to produce hot water at 55 ° by the selected heat pumps, are all features that allow a simplified system, which reduces maintenance and at the same time maximizes the efficiency of the entire building.

As for the air treatment units, it should be noted that the 31 WIZARD units were selected with the internal parts made of complete stainless steel, as required by the hospital applications. The AHU is serviced by service operators, where contamination between air streams needs to be avoided. In addition, the units are also equipped with high efficiency dual battery recovery systems. All AHU provided have the silent version to maximize the acoustic comfort of the patients, and with variable flow to reduce energy consumption of the building. It should be highlighted that the Climaveneta units comply with ErP, also known as Eco-design, the framework directive which, through national regulations governs the eco-design requirements for all energy-using products.

Cristiano Dal Seno, Climaveneta’s AHU Development Manager says: "The CTA WIZARD was born from the vast Climaveneta experience in the HVAC industry. It is a reliable and efficient product, successfully installed in numerous applications in hospitals around the world, where in addition to the comfort of patients and doctors it is necessary to ensure reliability and efficiency for air conditioning and air treatment." He continues: "In hospitals it is necessary to ensure the highest air quality, especially in environments where there is a high level of attention to patients and health operators. For this reason, we seek constructive solutions that facilitate the operation of a sanitizing unit with smooth surfaces and with minimal fissures. In addition, it is important to use of high quality materials capable of withstanding frequent cleanings with aggressive chemicals".

Efficiency, low noise, and reliability, these are the characteristics of a Climaveneta supply for the new emergency-urgency complex of the Hospitals of Foggia, which will be delivered by the end of this year to allow the start-up to be completed in time for the opening of the structure planned for spring 2017.

Bassano del Grappa January 2016: The complex of new South Padua United Hospitals is located in the middle of a large green area in Monselice and has a horizontal surface with three factory units for a total of 75,000 m2 of gross floor space. The buildings are no higher than three floors plus two technical levels. The profile of the undulating roofing recalls the landscape of the surrounding hills and allows the complex to fit harmoniously into the context in which it stands.

The topic of energy efficiency was vital from the beginning, in the first stages of the hospital design. The energy analysis that was carried out led to the choice of a tri-generation system based on 2 802 kWe engines and a 1900 kWf absorber. The advantages of a tri-generation system are the reduction of energy consumption and related emissions, the tax exemption for the purchase of natural gas and obtaining Energy Efficiency Certificates (EEC) with their consequent economic value.

To further increase the energy efficiency of the hospital, the tri-generation system has been supported by a geothermal field, consisting of 1,300 closed loop vertical probes. The probes are linked to 3 NECS-WN / B Climaveneta heat pumps, placed in plant rooms and directly connected to the collectors of secondary distribution. The geothermal field in winter produces hot water at 45 ° C (total capacity of 450 kW; COP 4.5), while in summer it produces chilled water at 7 ° C (500 kW EER 5.0).

Gemmo Spa, the company in charge of the M&E systems of the hospital, has chosen Climaveneta as supplier of the AHU. As a matter of fact even the air treatment system has been chosen for its high efficiency and is based on 132 WIZARD air handling units by Climaveneta for a total air flow of more than 900,000 m³ / h. All the components of the WIZARD units have been designed and carefully selected to meet the most stringent requirements of cleanliness and hygiene, typically required by hospitals, while ensuring maximum comfort and low noise levels in the rooms.

Cristiano Dal Seno, AHU Development Manager at Climaveneta says “The AHU Climaveneta produces are fully equipped with all the components required to always grant an optimal air filtration, humidification and heat recovery, in line with the Blessed Teresa of Calcutta hospital approach to sustainability. Granting the highest level of comfort in every project, in a green way, has been the Climaveneta mission for 45 years”.

At the Blessed Teresa of Calcutta hospital they have also installed 9 additional heat pumps for the active thermodynamic recovery in combination with the static heat recovery. Going in depth the plant designer has selected 8 NECS-WN / B and 1 RECS-W / B 2152 all supplied by Climaveneta for a total thermal capacity of 2.3 MW. This system combines a high quality standard while avoiding any air flow contamination and is able to supply almost constant power, both in heating and cooling mode, even in the case of outside temperature changes.

Moreover, the use of polyurethane prefabricated panel ducts brings significant advantages, including substantial noise reduction and above all a significant reduction in air loss and then of the treated air flow with a meaningful reduction in energy consumption.

Thanks to all these measures and to an integrated design of the building and systems, the total energy request of the hospital is 27% less than another equivalent hospital, compliant with legal standards. It is the result of an extensive experience and of an approach that, from a methodological point of view, could be favourably replicated in many situations.

Francesco Ortolani, General Manager of Gemmo SpA says :”We are proud of the great job we did at the Blessed Teresa of Calcutta hospital where, even thanks to the cooperation with partners such as Climaveneta, we have been able to create M&E systems able to combine reliability, innovation and energy efficiency”.

At the new United Hospitals in South Padua great importance has been given to earthquake safety. Hospitals are in fact called to play a very important relief role for the population in the case of disasters, as they must be able to ensure the first emergency medical operations. This implies paying special attention not only to the building’s structure but also to its plants that must be able to handle emergencies.

Even Climaveneta consequently verified the earthquake resistance of its units by installing special seismic dampers to the heat pumps, able to absorb the vibrations in the case of an earthquake and by subjecting the AHU to a careful structural analysis.

Reliability, energy efficiency and low noise emissions are the main factors that have always identified Climaveneta units and that have been essential in the construction of a modern hospital like the “Blessed Teresa of Calcutta” in Padua.
