10 FOCUS The NO FROST evaporator The evaporator used to evaporate the refrigerant in the circuit before sending it to the compressor and simultaneously to cool the fluid passing through it and that, ultimately, is used. Depending on the type of application are used several types evaporators and the most commonly used are: the plate evaporator and evaporator tube bundle. The evaporator is one of the most important components of the cooling system because when not performing their jobs well can cause serious and sometimes irreparable damage. The main danger lies in the ice. Precisely for this reason, Euroklimat deepened the research by developing a product that can keep the localized problem without involving the rest of the circuit: is born NO FROST evaporator. This type of evaporator, ensures great functionality in all conditions, even in case of fault. No Frost System 1) External case 2) Tank 3) Elastic sheath 5) Distributor 6) Alimentation circuits 8) Return circuits 9) Inlet gas pipe 12) Outlet gas pipe

11 FOCUS The concept of operation concerns the design feature of the heat exchanger that can be defined as a kind of tube in tube but with the outer sheath made of a special elastic material. The emphasis in the sizing of the heat exchanger, ensures a balanced distribution of gas in the circuits using the best game in the heat, ensuring optimum performance. The evaporator well thought out is part of a much larger container that has the function of the accumulator in a hydraulic circuit. To complete the system uses an expansion tank in order to absorb the expansion of the water circuit. The fluid that comes directly from the plant enters the heat exchanger and, after treatment, flows freely in the tank that serves as a storage and from there is sent to the system by closing the hydraulic cycle. In the case of the ice forming due to malfunction or breakdown, solidification does not occur to the interior by breaking the refrigerant piping and flooding the liquid circuit, but thanks to the flexible membrane and opening free accumulation, expanding to the outside without damaging the cooling system. In extreme conditions, where the whole system NO FROST should become a block of ice would melt enough to solidify this and resume operation without the traditional heavy remediation and restoration. The success of this product are a credit to Euroklimat that has seen their use in many refrigeration units. Patent since

12 FOCUS The compressors Euroklimat uses several types of compressors to meet the different needs of use: the classic scroll to the more traditional semihermetic alternatives. But the growing demand of the market, pushing Euroklimat to use on many products, the compressor semihermetic screw, especially in domestic, commercial and technological. The screw compressor, which has almost supplanted the use of the alternative, has several plus and has a longer functional life than its predecessors. The first major advantage is the increased resistance to the liquid slugging. The liquid is incompressible and so we need to make sure that the intake of the compressor is present exclusively in the gaseous state refrigerant. Often, the plant will recreate dangerous situations with the formation of moisture or liquid refrigerant returns. In the case of the alternative now would break the valves causing irreparable damage. The screw system is not immune from this problem, but bears better and to get a significant failure is necessary to operate in abnormal conditions marked or repetitive. The refrigerant is pushed, in fact, the rotation of two screws without end that in delivery do not require the traditional mechanical valves. Furthermore, careful design and refinement of the years, have led to a product with a number of mechanical parts and very low moving parts, therefore, with reduced possibility of failure. 12

13 FOCUS Main features The salient features are: A) innovative geometry of screw profiles B) high efficiency electric motor C) liquid separation by centrifugation D) volume ratio optimized E) calibrated screw lubrication F) mechanical engineering accurate and robust G) rolling bearings Oversized H) control capability easily and efficiently I) electric motor with split L) low noise and vibration M) ratio very favorable overall power N) minimum weight These Rotary displacement compressors consist of two trees and two screws with perpetual motion. The oil separator is flanged to the compressor. The representation of construction shows attention to detail and accuracy: 1) male screw 2) female screw 3) bearings 4) electric motor 5) intake valve 7) coalescing filter 9) connections for oil cooler external 12) filters 13) oil level indicator 15 integrated oil separator The control system capacity is achieved by a device variable volume ratio while the protection system consists of a fully integrated electronic device. 13

14 FOCUS The electronic expansion valve In the frigorific circuit, the expansion valve has a key role and its proper operation provides security to the system as well as optimize the operation from an energy standpoint. The more traditional expansion valves and more used up to now, are those defined as thermostatic with external equalizer. The main functions of this valve are mainly two: to reduce the pressure inside the circuit, setting the refrigerant evaporates, check the value of overheating, to ensure full freon gas inlet of the compressor. The action of this type of valve can be defined as thermoup of a membrane positioned within act three different pressures: that of evaporation, that of a return spring which also serves to superheat setting, the external equalizer, contrary to the first two. The answers so far are certainly valid, but limited in accuracy and, above all, the ability to adapt to sudden changes in operating conditions. Thanks to electronics, has led to a totally new valve: the electronic expansion valve. 14

15 FOCUS Perhaps, rather than a single element we should speak of the system because there are various components that make up this new system. The mechanical part that bears on the head of the electrical connectors, cables specially crafted link, the electronic management and control. The cards are also achieved by signals from temperature sensors and pressure scattered along the circuit. The Electronic Expansion System, after receiving information from sensors, compares the various parameters and sends the command to open or close mechanical element. But even greater is the evidence that all assessments are carried out in a very short time and then, the answer to the system is also very fast. Considering the change in operating conditions, a longer span of time, you get a linear response rather surprising. In some plants was measured energy optimization that led to a global savings of up to 15%, very significant value that drives us to think how important it is to make the right design evaluations. 15

16 FOCUS Electronic controls One of the strengths and quality of equipment is the accuracy and deepening management of electronic controls. The new microprocessorbased systems achieve levels of detail is absolutely incredible and the evolution of these systems offered the possibility to control not only the parameters of use but, more importantly, all functions and safety equipment stores. The electronics are basically divided into two basic parts: support for hardware and a program software. The hardware is made by the printed circuit boards where physically come all the signals from sensors placed along the circuit and where it triggers all the commands on, off, auto, block and counter. These signals can be either onoff as in the case of on / off a compressor, or as variables in proportion to the opening of a valve or a change in fan speed during a condensation control. In the software section, which consists of a computer program physically imprinted on a chip and placed on the Hardware tab, are written all the functions that the device must perform after receiving a signal, however, before sending any commands to the components of machine. While in the past to create a purpose it was necessary to combine the action of some electrical components, today is enough to write it to run. This fact has made it possible to chain several actions, perhaps even for the same function, and make much more sophisticated control or, even, as occurs in some cases carrying out functions that previously were not possible. 16

17 FOCUS LANs that arise through a simple electrical connection, allowing the dialogue more microprocessors and, therefore, more machines with the obvious advantages plant. Moreover, given the now widespread systems BMS for total control of buildings, we can interface with the microprocessor of the machines these devices even if the design language is different and, of course, just any producer. If you can not talk directly, you can refer to a communication protocol international, through which send their information to the outside. Global connectivity to all BMS controllers (Building Managemet System) 17

18 FOCUS Selection Software The most delicate problem of every modern company is to be able to provide rapid, accurate and complete informations. The evolution of communications technology has led to significantly reduce the time available to produce the answers and to make matters worse, the specialized technical / production which has been gaining increasing, has allowed companies to expand product capabilities and configurations. This has dealt a blow to that part of business that must oversee the preparation and communication of technical data or commercial products. Marketing efforts, documentation, the same sales and even the general trend of the company often depend on the capacity and speed to respond to market demand. 18

19 FOCUS Until the last century it was unthinkable to imagine multiple assessments, while rich in information, while immediate. You could certainly make an interesting document but at the expense of the timeframe for implementation or at the expense of accuracy. Fortunately, technology has also allowed in this area to find good solutions and helpful to the operators. Euroklimat has invested heavily in electronics because he always wanted to provide a serious service to its customers and after several years of discussions, research and improvements may present with pride Euroklimat Software Selection. In the vast range of products Euroklimat, this program is able to search, select and deliver the equipment or appliances necessary to meet the demand. The options are many, the flexibility is extreme. Machinetype silenced the use of heat recovery from the calculation easier with the nominal conditions for the dimensioning more complicated to use specific values, just a shot of clicks to get immediate answers analytical and articulate. Another great advantage of this software is the possibility to directly compare multiple devices and be able, therefore, without laborious manual assessment, to select the optimal product for energy performance, or for any other reason. At the conclusion of the selection, a large section devoted to print or export of documents in traditional formats, allows the production of processed clear and very well planned. The investment of Euroklimat is not limited to this aspect but is also developed through the WEB with innovative and useful services for all employees and users. The business is continually evolving and are prepared implementations and upgrades. 19
