The Research and Development department rely on a team of over 50 project design engineers fully dedicated to developing innovative solutions, using top level design engineering and simulation systems. One example is the four test labs, built between 2007 and 2010, where the units are put through tough test runs to verify and monitor their performances. Fully aware that each building has its own particular requirements in connection with the use in which the units are designated for, Clivet has gone beyond the product concept and developed complete and advanced systems tailor-made to suit various applications. These systems are capable of ensuring luxury comfort, efficient project development and installation time optimization. At the same time these systems have been designed with the environment in mind based on heat pump technology (geothermal concept). In this way this type of system is capable of providing comfort all year round while guaranteeing a save of 30 to 60% in primary energy and a 50% reduction in CO2 emissions. Plus it also uses renewable energy sources instead of fossil fuels used by conventional solutions.

The P-MATIC System

P-Matic MULTIPLEX CLIMA Edition is a solution specialized for centralized air conditioning system management in multiplex cinemas, designed and engineered by Clivet and based on modern, open and expandable technologies.

This system consists of a centralized supervision system based on the Movicon 11 Scada technology, which integrates perfectly with the Clivet rooftop air conditioning units. Full access to each unit’s working status, controls and parameters is guaranteed. P-Matic can also be used for managing air conditioners and the switching on/off of any other device connected to the system. It is very intuitive to use and has been designed using the Movicon 11 supervision platform functionalities. An extensive study carried out on intuitiveness and usability showed that choosing three-dimensional graphics for representing building structures with connected air conditioning units proved the most intelligent alternative. Due to the system’s simplicity of use even the the-not-so expert user can interact with the functioning of the, program them accordingly and to control operating status and alarms.

    1. Supervision composed of PC, Monitor, Printer and UPS. Centralized air conditioning system. The communication control panel established communication between the workstation and the Clivet rooftop units.
    2. Remote Client. Allows remote access to the supervision system using ADSL or local LAN network. The remote alarms are transmitted via modem or ADSL.
    3. Air conditioner ventilation Fan Control Panel: air conditioners can be adjusted to 3 different positions or set to modulate mode in combination with local temperature sensors.
    4. Temperature sensors: detect local air temperatures in the vicinity of each modular air conditioner unit to regulate air flow direction.
    5. Control Panel for managing other components: other components can be managed by using push button commands (ON/OFF), alarm status.

 

    1. Controlled Clivet units (ranging up to 36 Clivet rooftops from the CSNX-XHE, CSRT-XHE, CSRN-XHE, CKT-XHE e CKN-XHE series). Communication is managed using two RS485 serial lines. Each serial line can connect up to 18 Clivet rooftops.
    2. Air conditioning ventilation fans: Each rooftop unit can be assigned up to 3 groups of diffusers adjustable to 3 positions or self adjusting. Each panel can manage up to 6 rooftop units. The maximum number of panels allowed is 6 therefore 108 groups of diffusers can be controlled.
    3. Other components: Automatic control of components such as extraction ventilators, split conditioners, illumination and other, using push button commands (ON/OFF), alarm status.

 

The programming of the entire managerial system along with controlling each unit’s operating status and maintenance checks can be done directly from the Control Room or by remote control, using the network feature. The centralized control system fully supports remote client and Web architecture for remote access using Web browsers. P-Matic is the result based on choosing avant-garde components to guarantee maximum reliability. It includes a security system which provides a password and users management involving Log On authentication procedures, a data backup program and an UPS, uninterruptible power supply PC connection.

Continuous controlled climate

Wellness in terms of temperature, humidity and air quality for the spectators in the foyer is one of the essential features that make spectators willingly go to the cinema.
P-Matic manages control set points in each supervised zone as well as in each unit. It purifies air in the auditorium at the end of each film showing and allows air conditioning to work in custom night mode to save on energy. Air distribution can also be managed from the supervisor using different logic: fixed position or automatic wing adaption ventilation fans.

Units can be programmed to work on a yearly cycle basis and each unit can be controlled with top precision to improve unit performance zone by zone. Benefits in terms of operation costs derive from providing thermal energy or cooling only where and when needed, gaining a greater advantage in saving on energy and quick return of investments.

The Clivet rooftop units have perfectly integrated with the Movicon supervision system in terms of functions and parameter settings and together lay the foundations for achieving energy optimization.

Considering that cinema staff on the whole are not usually air conditioning specialists, the P-Matic system has been designed for easy interaction without disturbing the normal running of the cinema.

Navigating the P-Matic supervision screens is extremely intuitive and easy with building and air conditioning unit represented in tridimensional graphics. Managing alarms locally or by remote control and scheduling maintenance interventions are indispensible to ensure that these systems work continuously and perfectly.

Even the not-so-expert user can interact and program units to work as required and check the status of alarms displayed as animated graphics on screen.

Clivet’s choice of using the Movicon software platform for its systems was influenced by Movicon’s simplicity- of- use and great deployment flexibility. These characteristics enabled Clivet to use just the one software platform for all tertiary and industrial air conditioning systems implemented with PC use.
Clivet offers the residential building sector a yearly pump heating cycle application that uses solar energy to guarantee complete comfort all year round using one single system operated by Android. The Android platform was chosen for this application because it is the most commonly used end-user and open source usable in all portable devices such as mobile phones and tablets. Quick to use it is can also be integrated with smart home systems.

Application example:

CINESTAR AVENUE MALL Novi

Zagreb, Croatia (Multiplex Cinema with 9 theatres)

CineStar Avenue Mall is located in a shopping mall and is one of the main entertainment attractions in the capital city of Croatia. This cinema offers modern digital projection systems to more than 1,900 spectators and more that 500 seats in the adjacent restaurants, cafes and bars.

The Blitz-CineStar is the first chain of mulitcomplex cinemas in Croatia. With years of experience as major Croatian Blitz Film and Video distributors, they joined together with the German CineStar operators to provide the Croatian public the best services in terms of comfort, technology and film viewing. Today it has a chain of multiplex cinemas with an overall total of 74 auditoriums providing over 14,000 seats.

The Challenge

The second multiplex Blitz-CineStar in Zagabria wanted to realize its ambitious plan to expand the group as the most modern, attractive and technologically advanced cinema chain in the whole of Croatia. It was adamant to ensure that spectators got maximum comfort all year round especially in the cold winter climate conditions of Croatia’s capital city. Air also had to be purified and treated according the stringent hygiene standards covering the public sector. In addition, they were faced with two challenges to overcome certain constraints. The first challenge was represented by an overload variability that occurred with overcrowded closed in space.

such as cinema auditoriums. To remedy this problem it was necessary to engineer an air conditioning system for the entire building and provide electric power for the central heating and cooling systems as well. Appropriate adjustments needed to be implemented to ensure that the different system components worked autonomously as required. At the same time, a way needed to be found to improve energy efficiency to allow reductions in energy consumptions and managerial costs. It was apparent by the architectural plans that space and structural layout available for implementing such technological systems were insufficient to satisfy all these demands at the same time. The second challenge came from the complexity of the building layout and tight deadlines which placed more emphasize on trust in their planning skills and ability to delivery on time.

The solution

The CineStar Avenue Mall has also deployed the Clivet Multiplex Solution for centralizing air conditioning systems. Their mono block reversible heat pump rooftop units are compact and capable of working at very low temperatures. Each auditorium has been installed with a unit specialized for maintaining ideal air conditioning when becoming very crowded. These machines are capable of treating a greater amount of external fresh air than any generic commercial rooftop application, where the number of people per unit area is usually less than 80%.

The Units also include electronically controlled fans for constant air flow. They have highly efficient thermodynamic energy recovery on expelled air and gas reheating to control humidity in hot air climates and during hot seasons to recover heat condensation otherwise exposed of externally. Even local venues, such as bars, shops and restaurants, use rooftop air conditioning units with cooling/refrigeration circuits and reversible heat pumps that are more specific for less crowded places.

The whole system is controlled by the P-Matic Clivet centralized supervision system based on the Movicon 11 Scada platform, which displays information on comfort in the various indoor ambient, system and air conditioning unit status. Each unit can also be programmed automatically based on the conditions desired with prescheduled operating times.

The results

The compactness of the Clivet Mutliplex air conditioning solution has made full use of the limited rooftop space available based on the roof’s structure incidence averaging 250/m2. Since this is a specialized system, temperature, humidity and air quality controls are performed automatically throughout a yearly cycle to keep the desired conditions maintained in all the areas concerned. During the winter season the Clivet Multiplex Solution operates up to -12°C outdoor freezing conditions with 20°C indoor conditions with the aid of the auxiliary hot water battery provided for specific cases. From the managerial and environment point of view point, the combination of decentralization and high energy efficiency of the air conditioning units saves more than 40% on energy in respect to hydronic central heating systems. The industrialized construction of the units, which contain most of the system components within, has made onsite work quicker in assembling and testing within the agreed deadline and delivery times.
