Carel electronic expansion valves are designed to meet any cooling capacity requirements up to 2000 kW in air-conditioning and refrigeration applications, and stand out above all for their excellent flow control, even at lower flow-rates.
Carel expansion valves have three main strengths:
1. Reliability over time: the standard design process used for the Carel ExV valves includes accelerated life testing of 1*106 cycles; the valves are certified in accordance with the main national and international standards; compliance with these standards guarantees maximum quality of both the products and the manufacturing process, as well as continuous commitment to improving the environmental management system.
2. Very precise control: this is guaranteed by Carel electronic controllers, designed especially to optimise management of air-conditioning and refrigeration systems, with special focus on energy saving. In addition, highly precise control is also assured by the special shape of the movable elements, guaranteeing flow with an equal percentage characteristic, the stroke length, achieved by using stainless steel ball-bearings, and the use of high precision mechanical components.
3. Perfect refrigerant tightness: despite the rotary motion of the motor, the movable element does not rotate during movement. This allows the use of a high quality Teflon seal, which rests gently on the valve seat, without any sliding. To improve tightness of the seal, an elastic steel spring is fitted that pushes the movable element against the seat when the system is closed: this moreover allows the motor to complete a number of extra turns before stopping. The energy accumulated by the spring in this stage gives additional energy to close the valve, meaning tightness values that are comparable to those provided by a traditional solenoid valve.
Finally, testing of 100% of the valves manufactured provides a further guarantee of reliability over time and valve tightness, and helps ensure operations with a reduced environmental impact.

Hecu Sistema is the CAREL solution for commercial refrigeration, designed for high energy efficiency condensing units that use either traditional HFC refrigerants or natural refrigerants such as CO2.
The system’s distinctive features include the use of DC inverter technology and real-time synchronisation with the refrigeration units. Hecu sistema meets the requirements of the latest environmental sustainability standards relating to energy consumption (Eco-design directive) and the use of low GWP refrigerants (F-Gas regulation). Stable control means high-quality food preservation and a drastic reduction in waste.
Hecu sistema is also compatible with all CAREL supervisors, which can monitor each individual system or groups of systems, and offer dashboards to simplify interpretation and analysis of system operation.
Heos System is the new concept offered by CAREL for commercial refrigeration. A new way of developing refrigeration systems that comprises plug-in cabinets featuring simple on-board refrigeration units with DC inverter compressors. The heat of condensation is carried outside of the store via a simple water loop, which is in turn is cooled by an outdoor dry cooler.
Heos es el nuevo sistema ofrecido por CAREL para la refrigeración comercial. Una nueva forma de desarrollar sistemas de refrigeración que comprende cabinas plug-in con unidades simples de refrigeración con compresores de tecnología DC inverter. El calor de condensación se lleva fuera de la tienda mediante un simple circuito de agua, que a su vez es enfriado por un dry cooler situado fuera.
Nueva normativa sobre refrigerantes y eficiencia energética: ¿Estamos prepara...CAREL Industries S.p.A
Actualmente, las normativas internacionales se centran principalmente en la reducción de las emisiones de CO2, tanto directa, a través del uso de gases refrigerantes con un menor GWP, como indirectamente, disminuyendo el consumo de energía en los equipos. En Europa, las normativas F-gas, Ecodiseño y Etiquetado Energético están indudablemente dictando la evolución del mercado de la climatización y la refrigeración. Por ello, las novedades en el sector van encaminadas a diseñar equipos cada vez más eficientes desde el punto de vista energético y compatibles con los refrigerantes con bajo GWP. Otros factores que influyen en las nuevas tendencias son la evolución de los precios de los refrigerantes, así como la disponibilidad y los inconvenientes de las nuevas alternativas.
En este escenario, la presentación "Nueva normativa sobre refrigerantes y eficiencia energética: ¿Estamos preparados?" tiene como objetivo encuadrar el marco normativo que afecta al sector de la climatización y la refrigeración en Europa y analizar las opciones disponibles en la actualidad para respetar dicha normativa. Entre ellas, las tecnologías y soluciones avanzadas de control compatibles con las nuevas alternativas de refrigerantes y que ayudan a respetar los límites impuestos.
In latest years the use of waterloop systems in commercial refrigeration has seen a great boost thanks to the use of DC inverter driven compressors that have significantly improve the energy efficiency of this kind of systems.
The synergic use of DC inverter driven compressors and electronic expansion valves jointly managed by advanced control systems permit to combine the typical benefits of a waterloop system, such as factory tested plug and play cabinets, flexibility and charge/leaks reduction, with energy efficiency, food quality improvements, regulation stability and prehentive diagnostics.
CAREL is continuously improving its Heos sistema for DC waterloop systems, presenting how this technology can further improve the system analysis to a cabinet vs cabinet level, details not available with traditional systems, and how the benefits of this systems can be adapted using different refrigerants.
Energy saving through evaporating cooling in comfort and industrial applicationsCAREL Industries S.p.A
Everybody has certainly experienced the cooling effect caused by a current of air on the sweating skin or on wet clothes, as well as the perceived lower temperature in the vicinity of waterfalls where microscopic water droplets are suspended in the air.
Based on empirical observations, even without knowing its basic physical principle, humankind has used since from the third millennium B.C. the evaporative cooling to mitigate the temperature of spaces, particularly in areas with a hot and dry climate.
Only over the last two centuries, scientists have studied the basics of thermodynamics and processes related to the exchange of sensible and latent heat and found the theoretical principles of cooling by evaporation which, however, has played a marginal role in the recent past due to the extensive use of mechanical refrigeration systems.
Air can be effectively cooled by exploiting the evaporation of water atomised into very fine droplets: the change in state, from liquid to vapour, absorbs energy from the air, which is consequently cooled. Evaporation of 100 kg/h of water absorbs 69 kW of heat from the air, for power consumption of less than 1 kW!. In an air handling unit, the supply air can be evaporatively cooled and humidified (direct evaporative cooling, DEC). Alternatively, if the outside air humidity is already high, the exhaust air can be cooled by several degrees without limits in terms of humidity, as it is discharged by the AHU; this cooling capacity, using a heat exchanger, can be used to cool the incoming fresh air with an efficiency that depends on the heat recovery unit used, yet easily exceeds 50%! (indirect evaporative cooling, IEC). All this means lower unit energy consumption and smaller dimensions and capacity of the cooling coil and chiller.

The use of CO2 in Europe as refrigerant in commercial refrigeration is getting more and more common. Starting from the big compressor rack for hypermarket, then with small and cost effective solution for small supermarket, now the attention of the industry is moved to small condensing unit for C-Store and very small formats.
The technology applied in the compressor rack application is not directly applicable in the condensing unit world, historically driven by initial cost and ease of use.
CAREL is offering now a full solution for CO2 transcritical condensing unit able to guarantee
- Energy efficiency thanks to specific components able to work at very high pressure but specifically design for such small capacity
- DC compressors technology to further improve the energy efficiency not reachable
- Full control of the system to guarantee best perfomances and reliability
- Advanced display and remote connection to maximize the ease of use.
CO2 transcritical condensing unit are available in the market since years but never getting the appropriate success due mostly to unavailability of adequate components (especially compressors) to correctly place this solution into the market.
CAREL already market leader of this application is now proposing a new solution equipped with DC compressors that are able to improve the performances and at the same time reducing overall costs and dimensions of the whole unit.
This speech informs about the excellent key performance factors of BLDC technology in this application and explains the specific control and system demands.

Vorstellung Anlagenkonzept einer Wohnraumlüftungsanlage mit integrierter EC-Inverter-Wärmepumpe zum Heizen, Kühlen und zur Brauchwasserbereitung.
Durch die Nutzung der Abwärme des Gebäudes als Wärmequelle der Wärmepumpe wird ein hoch effizientes System geschaffen. Des Weiteren gewährleistet die EC-Inverter-Technik, durch ständige Anpassung an den Gebäudebedarf, eine hochpräzise Temperaturführung und eine optimale Energienutzung.
Zudem ermöglicht der Einsatz von Wärmepumpentechnik den reversiblen Betrieb (Heizen und Kühlen) und liefert dadurch einen enormen Komfortgewinn, speziell in der Sommerzeit.
Ergänzend dazu haben wir die Integration eines Ultraschall-Befeuchters in der Anlage zur Befeuchtung in der Winterzeit und adiabatische, indirekte Kühlung im Sommer untersucht.
Durch die Befeuchtung in der Winterzeit wird der Komfort gesteigert. Durch eine optimale Befeuchtung werden gesundheitliche Risiken durch trockene Luft, wie trockene Haut, trockene Nasennebenhöhlen, trockene Kehle, Nasenreizungen, blutige Nasen, trockener Husten, rissige Lippen vermieden. Des Weiteren schützt es Ihr Haus und Einrichtungen durch Reduzierung des Risikos von Holzverwerfungen und Rissbildungen.
Darüber hinaus benötigt die Ultraschalltechnik gegenüber Dampfbefeuchtung einen sehr geringen Energieeinsatz.
humiSonic direct was awarded in Mostra Convegno Expocomfort 2016 as one of the most efficient and innovative humidification systems.
This humidifier stands out thanks to its excellent performance, that guarantee maximum reliability and minimal maintenance, 90% energy saving compared to a steam humidifier and instant absorption of the nebulized droplets.
Thanks to the low consumption of energy humiSonic is the ideal solution for data centers and for all those applications in which humidity control can be carried out at the expenses of the sensible heat generated within the room.
The environment as well takes advantage of humiSonic’s high efficiency. If used to replace an isothermal system in a small data center, with a humidity request of 10 kg/h, the emission of 9 tons of CO2 each year would be avoided.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Effects of the transition between HFCs and their alternatives
• Specific unit design may cause initial poor unit design due to lack of competences or time
lower efficiency
• Compromises natural refrigerants and low GWP HFO blends are not designed to be “good
refrigerants” only, they are a compromise between different needs
lower efficiency vs HFCs
• Increased unit cost propane and CO2 require a specific components and safety devices (what about
ROI?)
higher efficiency is needed vs HFCs
• Increased unit displacement CO2 requires extra components and pipings to work properly
wise use of space is needed

Technologies: DC compressors
On-Off cycling is not efficient as the
refrigeration circuit needs time to reach the
nominal efficiency. Part load conditions (i.e.
25%) won’t allow to reach nominal efficiency.
Average efficiency is very low.
This area represents the increase of
efficiency at part load. It’s bigger with a wider
DC compressor capacity range
A refrigeration application is working for the
largest part of the time at partial load
