the new standards. Rather than to cut beds, the idea was to reorganise the existing structures, streamline small regional centres and strengthen the main hub. Among the centres is the University Hospitals of Foggia, the second largest hospital of Puglia which aims to achieve the ambitious goal of becoming a hospital of excellence where all the functions of modern medicine are available. To achieve this goal, work is underway to build a 250-bed emergency complex which will be completed in the spring. In healthcare 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.
Focus on HVAC
The new complex of the Hospitals of Foggia was fitted with an air conditioning system based on five Climaveneta chillers and heat

pumps with high efficiency, combined with 31 WIZARD air handling units. In more detail, there are; one multi- purpose heat pump ERACS-Q / SL-CA 3222, one reversible heat pump FOCS-N / SL-4822 and three 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: 3183kW for cooling and 1909kW for heating. Hospital HVAC systems should always be slightly oversized, firstly to ensure continuous operation in case of failure or maintenance of a unit, and secondly because hospitals are continuously evolving, linked to the development of medical technology, the possible changes in user requirements, and also possible future expansion. 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 minimising 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 maximises 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 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. The Climaveneta units comply with ErP/Eco-design, the framework directive which 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 sanitising unit with smooth surfaces and with minimal fissures. It is also important to use high quality materials capable of withstanding frequent cleaning with aggressive chemicals."
