1. PRODUCT PRESENTATION NECSQ This section contains general information on the NECSQ range of products. For detailed information refer to the speci c sections in this bulletin. 4pipe systems This type of system is suitable for airconditioning buildings that require separate areas to be heated and cooled at the same time. It is combined with centralised solutions capable of producing hot and cold water in the two hydronic circuits of the system, assuring maximum comfort in every room of the building, independently and in any period of the year. From now on, a single intelligent unit is suf cient for the management of these complex systems: INTEGRA. INTEGRA unit for 4pipe systems, air source for outdoor installation The NECSQ series multiuse units are able to simultaneously meet hot and cold water production requests and are thus a valid alternative to traditional systems based on chillers and boilers for applications such as of ce blocks, pools and shopping centres. The advanced control logic, developed by Climaveneta, ensures that heating and cooling loads are perfectly met. When these are simultaneous, the unit exchanges evaporation and condensation heat with the system cooling and heating circuits respectively. When heat loads are not balanced or one of the two are missing, the unit automatically switches to a third heat source which can be air or water according to the model. The NECSQ are units for outdoor installation. For these products. heat is exchanged on the source side by a refrigerantair coils exchanger; it acts as a condensert or as an evaporator according to machine conditions. CA version unify in fact a premium ef ciency level as well as a quiet operation at all working conditions. All standard units can be also provided with the compressors acoustical enclosure that can reduce the sound power level by 2dB(A). Innovative fan management system Climaveneta has designed a new system on how to manage the condensing fans with a complete new structure of the ventilation section (patent pending). This allow to ensure outstanding performances in terms of ef ciency in all the operating conditions, thank to: elimination of the reciprocal dependency on adjacent circuits ability to manage independent defrost cycles on different at different time in different circuits a more accurate fans speed management and, as consequence, a lower power consumption. 1.3 Efficiency (Class A) NECSN units are available in the CA version, with Class A ef ciency levels in the heat pump mode according to the Eurovent performance tables. These units exceed the minimum winter mode ef ciency requirement assuring a COP 3.2, while in the summer mode they assure an EER 2.9. 1.4 Hydronic unit The integrated hydronic assembly includes the main hydraulic components, with a low or highhead pump and storage tank. Automatic pump rotation system in the event of a breakdown without interrupting operation (only in units with a twin pump). 1.1 Refrigerant gas R410A The use of R410A has resulted in units offering better energy ef ciency in full respect for the environment (ODP = 0). 1.2 Unique proposal Maximum Reliability Unit with multicircuit chilling section (two to four, depending on the size) designed to ensure maximum ef ciency both at full load and at part loads, assuring uninterrupted service in the event one of the two circuits fails. The number of compressors also ensures a precise multistep management of the cooling and heating capacity provided by each units. VShaped coil geometry Open angle vshaped coils for achieving the maximum ef ciency a all conditions. A speci c design of the condensing modules allow to reduce the units footprint as well as the clearances, thus facilitating service and maintenance operations. The structure is also designed to allow the easiest access to all the components in order to simplify maintenance work. Heat Pumps at 12 C outdoor temperature NECSQ models host several cuttingedge implementations, focused on the ef ciency and extended operation in winter mode, also with harsh outdoor conditions. Heat pumps can in fact be equipped with the LT low temperature option. This includes speci c regulation which activates adequate refrigerant injection, allowing to achieve 10 C for the SL versions and 12 C the CA versions. Silent Versions Combined with the Class A versions, the sound power level is also a distinctive feature on the new NECS range. The new SL III NECSQ_1314_3218_201005_GB HFC R410A

3. ELECTRONIC CONTROLLER NECSQ 3.1 CONTROL UNIT with LED display The W3000Large control unit with liquid crystal display (LCD) is tted on all the units. This keypad uses a user interface with a choice of seven European languages: Italian, English, French, German, Spanish, Swedish and Russian. This allows the control unit interface to be chosen to suit the country of destination or, thanks to English, to be completely independent for all geographical areas. This type of operator panel is also available as a remote keypad, to be connected to the unit by means of a serial connection up to a maximum distance of 200 metres without a power supply (in this case, power is supplied by the unit), or a maximum of 500 metres with a dedicated local power supply. It is possible to interface with commercially available BMS systems as it is compatible with the BACnet, BAC net OverIP, ModBUS and LonWorks protocols. The Black Box stores 200 alarm events; these can be printed with any kind of personal computer. The Internal Clock manages a weekly scheduler organised into time bands in order to optimise unit performance by minimising power consumption. Up to 10 daily time bands can be associated with different operating setpoints. As a result, power production is optimised during daily peaks of demand and minimised during periods of inactivity, such as during the night. If there is no demand for hot or chilled water, the clock can switch the unit off and switch it back on later. Heat adjustment is performed using algorithms based on proportional step control or on proportional/integral on the two probes at the inlet and outlet of the heat exchanger. There is also the QuickMind algorithm which was especially developed by Climaveneta to ensure the unit operates correctly even with systems featuring a low water content. QuickMind is a special control unit which monitors the main operating parameters, predicts system behaviour and anticipates unit settings in order to constantly optimise performance; it allows both return and delivery water temperatures to be chosen as adjustment parameters. It can reduce outlet temperature uctuations even with a small amount of water in the system. When, for dualcompressor chillers featuring a maximum of 12 startups per hour and using a traditional adjustment system, the minimum recommended water content is 5.5 l/kw, Quick Mind ensures the same chiller operates correctly even with a water content of just 2.5 l/kw and considerably reduces outlet temperature uctuations. The above graph shows that outlet temperature uctuations with QuickMind are limited to 4.3 C as opposed to 7.54 C if the traditional adjustment system were used, without even ensuring an acceptable minimum compressor start time. 4 NECSQ_1314_3218_201005_GB HFC R410A

ELECTRONIC CONTROLLER NECSQ Remote keyboard As an alternative to the standard keyboard, the NECS has a W3000 Compact operator panel with liquid crystal display. (LCD) This keyboard employs a user interface with 3 European languages that may be selected by the user, two of which are preset, and a further language of choice which may be French, German, Spanish, Swedish or Russian (to be speci ed on order). This allows the control unit interface to be chosen to suit the country of destination or, thanks to English, to be completely independent for all geographical areas. This same type of operator panel is also available as a remote keyboard, to be connected to the unit by means of a serial connection up to a maximum distance of 200 metres without power supply (in this case power is supplied by the unit), or a maximum of 500 metres with dedicated local power supply. 5 NECSQ_1314_3218_201005_GB HFC R410A
