The E2V-F series
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.

The document discusses gas cooler design considerations for CO2 refrigeration systems. It describes how using smaller diameter copper tubes of 5mm allows for more compact gas cooler designs that can withstand higher pressures of up to 130 bar. This reduces the internal volume and refrigerant charge compared to traditional designs. Case studies show how CO2 gas coolers using 5mm tubes can achieve equal or higher capacity compared to R404A designs, using fewer fans and a more compact footprint. The technology allows for more efficient gas cooler designs well-suited for transcritical CO2 refrigeration applications.Clare Perry, Environmental Investigation Agency (EIA)
The document discusses illegal trade of hydrofluorocarbons (HFCs) in the European Union and recommendations to strengthen enforcement of the EU F-Gas Regulation. It finds that over 16% of the EU's 2018 HFC quota was smuggled into the bloc, equivalent to 4 coal-fired power plants' worth of emissions. Common smuggling methods like mislabeling cylinders and using disposable cylinders are described. Weaknesses in customs enforcement like the lack of real-time quota data and exemptions for small shipments are also noted. The document recommends improving licensing, transparency, banning disposable cylinders, increasing penalties, and aligning the quota system with climate goals to curb illegal HFC trade and emissions.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
