Screw compression at CO2 Liquefaction Facility:   Slide Valves VS. VFDs  |  𝗪𝗵𝗶𝗰𝗵 𝗼𝘂𝘁𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝘀? We took a 1000 metric ton per day (MTPD) CO2 liquefaction facility that used screw compression as the main driver for product and for refrigeration.  We compared both performance and energy consumption of the screw compressors using slide valves and VFDs.  VFDs offered significant benefits in terms of: ▶ efficiency,  ▶ reducing operating costs, and  ▶ providing a lower carbon intensity for the ethanol product. Using VFDs to control the capacity of the screw compressors resulted in ….   an 18% reduction in power consumption, compared to using slide valves! This translates to an 𝟭𝟴% 𝗿𝗲𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝗶𝗻 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗻𝗴 𝗰𝗼𝘀𝘁, which amounts to $3,248 USD per day in savings from lower power demands.  ------  Read the entire analysis on the blog (link in comments). What is your experience with slide valves and VFDs? Have you seen similar results? 👀

Once upon a time chillers and heat pumps were mostly measured on full load efficiency. Once upon a time chillers and heat pumps were mostly based on a couple of refrigerants with some exceptions linked to the specific applications. Once upon a time the components manufacturers were periodically chasing the OEMs Manufacturers for moving to new fully proofed and developed components providing higher efficiency or better envelope or better costs.   Today the units need to comply with progressively more challenging seasonal efficiencies either to enter into the market or to access to local incentive programs (in Italy we are still stuck with a legacy incentive program looking only at full load, but that’s another story…) Today you can chose the refrigerant from the refrigerant list… Today as OEMs we co-develop in parallel with the components manufacturers considering some of the upcoming legislative revolutions.   This is the result of the joined efforts between a greatly dynamic industry sector and an ambitious legislative framework. In Swegon I can say that we started developing similar products always quite before the bindings legislative thresholds, being this part of our DNA and our strategy, and being this in line with our customers’ expectations. Anyhow the big market shift (the one moving the largest part of the end users) generally needs to have also a push from the regulators.   That’s why I think we need from the European Commission the same level of ambition shown with the F-Gas revision, the past LOT 21 revisions in the upcoming definition of the Fossil Fuel Boilers (to complete the just published EPBD revision) and the future LOT 1 revision!   So we will be able to finally complete also this story: once upon a time we were inefficiently burning to heat up ourselves and today… #EPBD #CleanHeating #HeatPump #Lot1 #FossilFuelBoiler

Y'all...there seem to be a lot of rumors going around about "BIG PRICE INCREASES" from heat pump manufacturers in conjunction with the new refrigerants (R-32 and R-454b) that will be used for equipment manufactured 1/1/2025 and beyond (some equipment is already in production). But at least so far, we're not seeing these price spikes in reality. Price increases for the first batch of R-32 equipment models from our Daikin distributor look to be quite modest...yielding about +$200 per average heat pump system to the bottom line of a quote to a client. This doesn't seem very scary! What is everyone else seeing? Real prices only. No rumors.

As a non-toxic, climate-friendly refrigerant, CO2 is becoming increasingly important. In industry and commerce, where systems with large capacity and high efficiency are required, CO2 is often used in cascade cycles together with the thermodynamically very powerful NH3. Thanks to the CO2, the ammonia filling of the system can not only be reduced by around 80%, but also limited to the engine room, where the consequences of a leak or spill are very low. However, the use of CO2 is not entirely without problems: it requires high system pressure and a limited operating temperature range of -53.9 to +26.7 °C. This makes it all the more important to have an optimally configured refrigeration system that is tailored to these high pressures and temperature ranges. As an expert in CO2, HERMETIC has been supplying leak-free pumps with double safety covers for these demanding conditions for decades. Our canned motor pumps ensure that CO2 is pumped reliably and safely in more than 5,000 refrigeration systems worldwide. The highlights at a glance: ❄ Standard and high-pressure version: High-quality and reliable standard cold pumps for a wide operating range in PN 40 ❄ Improved hydrodynamic bearing and high pressure design (PN 52 / test pressure: 78 bar) offer excellent durability under the most demanding conditions when dealing with CO2 ❄ Includes HERMETIC ZART® (Zero Axial and Radial Thrust) technology for wear-free operation Would you like to know more about the efficient use of CO2 as a refrigerant?

A Quick Look at the Refrigeration Cycle ❄️🔄 The refrigeration cycle is a key process in cooling systems ,used across industries and our daily life. The cycle consists of four key stages: 1️⃣ Compression: The refrigerant gas is compressed in a compressor, increasing its pressure and temperature. 2️⃣ Condensation: The hot, high-pressure gas flows into the condenser, where it releases heat to the surroundings and cools down into a liquid. 3️⃣ Expansion: The liquid refrigerant passes through an expansion valve, where it experiences a drop in pressure, becoming a low-pressure liquid. 4️⃣ Evaporation: The cold, low-pressure liquid absorbs heat from the surrounding air (inside a fridge or AC), turning back into a gas, and the cycle repeats. This continuous loop allows for efficient cooling by transferring heat from one area to another. #Refrigeration #Thermodynamics #CoolingSystems #HVAC ##ProcessEngineering

Why Do Compressed Air Systems Need Drying? Jemaco provides compressed-air dryers and filters that remove oil, water, dirt, rust and pipe scale. Contaminants found in compressed air can adversely affect all components of an air distribution system, and can cause a malfunction of pneumatic control in the instrument air system. Properly treated compressed air can improve work efficiency and reduces maintenance! 👍

The modified Pulse-Tube Refrigeration technique is more efficient because it better manages the flow of helium gas during the cooling process, reducing the amount of helium wasted. This efficiency could decrease the cooldown period from a day to just a few hours, potentially accelerating numerous scientific and industrial processes. https://lnkd.in/dKmPTJk2

As a fuel filter supplier, we often get asked about pressure and vacuum readings (The Separ SWK2000 range is a suction side filter). With SI units, both BAR and BARG are units used to measure pressure, but they represent different concepts: BAR Represents an absolute pressure. This means the pressure is measured relative to a perfect vacuum, where there are no air molecules present. It provides a more fundamental and accurate picture of the total pressure acting on a system. Whereas BARG (or BAR G, BAR-G) Stands for gauge pressure. This means the pressure is measured relative to the ambient atmospheric pressure. Gauge pressure is more commonly used in everyday applications because it considers the surrounding air pressure, which remains constant in most situations. So if you are reading a vacuum or pressure on a dial gage on a filter, that is going to be BARG. Simply put, on a filter with a dial gauge, a reading of 0 is atmospheric pressure (0 BARG). So a filter restriction on that dial gauge, for example a vacuum of -100mabr, will be -100barg. The choice between using BAR or BARG depends on the context: Use BARG when you're interested in the pressure difference between a system and the surrounding environment. This is relevant for applications like measuring tire pressure, air compressor output, or pressure in a closed container exposed to the atmosphere. Use BAR when you need the absolute pressure and the surrounding air pressure is irrelevant or needs to be accounted for separately. This is important in scientific calculations, vacuum technology, or situations with significant changes in altitude. Converting between BAR and BARG requires knowing the current local atmospheric pressure. You can add the atmospheric pressure (usually measured in bar) to a BARG value to get the absolute pressure (BAR). However, remember that the atmospheric pressure can fluctuate slightly depending on location and weather conditions, making the conversion inexact for precise measurements. Gauge pressure readings are usually positive because the pressure inside a system is typically higher than the surrounding air. However, it can be negative in situations where the pressure inside the system is lower than the atmosphere (like a vacuum).
