Cold Plasma, Clean Air, And Energy-Zapping Bacteria With Oxygen Atoms

Squair Cold Plasma TechnologyCold Plasma, The Next Step In Home Pollution Control

Cold Plasma in the news: Let’s have clean air by putting the power of cold plasma into handheld technology.

It’s coming from Germany where a team of inventors is working to enable in home pollution control via advanced non-thermal plasma (NTP) know-how. The device, tagged the Squair, is designed to safely split oxygen molecules into clean air bacteria collection agents. If promises are fulfilled as stated by the inventors, the Squair portable air cleaner will activate the natural atmosphere within your home so that portable pollution control becomes more effective than ever before.

Current air cleaners zap pollutants with negatively charged ions. But the Squair process ups the ante. According to the inventors, the Squair cold plasma device can provide every homeowner with portable access to a double-dose pollution control particulate zapper. By making use of both negative and positively charged particles, the new process gives homeowners two cleaners for the cost of one cleaner. Just call it a portable, dual-efficiency clean air booster system.

TIP! Clean your permanent air filters or replace disposable ones every single month. If you have the choice, an electrostatic is the best option on the market today. For professional HVAC maintenance call now.

In typical plasma production, energy blasted into gas results in split molecules of both positively charged electrons and negatively charged electrons. Furthermore, the end result is not termed “safe for human touching.” According to the Urban Clinic, plasma air cleaning devices are designed to replicate the negative ions found in nature and in indoor settings. In theory, these ionizing devices emit particles that cling to bacteria, mold, viruses and even things that just smell bad. Plasma technology produces hydroxyls that attack airborne pollutants.

A recent release from the Journal of Medical Microbiology projects that cold plasma jets may be a safe and effective alternative to antibiotic treatment of multi-drug resistant infections. Defined as the fourth state of matter after solids, liquids and gases, plasmas are the result of high-energy stripping of atoms from their electrons. It’s a high temperature process wherein hot plasmas are used to disinfect surgical instruments. Furthermore, plasma pollution control results in an increase in home ozone levels.

However, the Squair cold plasma approach produces molecules that are near to room temperature and safe for use within the living room, bedroom or anywhere else within your home. With cold plasma technology, you get a safe air cleaner that uses fewer ionized molecules (thus less ozone) while also reaping greater effectiveness as a personal pollution management device.

TIP! Before having someone install, maintain or repair HVAC components, make sure they are insured. Having someone who is insured work on your system will assure that if anything happens while they are working at your home, they are financially covered and you will not be responsible.

 

According to Squair, this clean air device is a win-win solution. The inventors define the technology as effective in fighting bacteria, germs, fungi, mold, and viruses. Each portable device is crafted to handle 322 square feet. Florian Windeler, company CEO, defines it as a plug-n-go air cleaner solution that will work in homes, offices and even cars. With cold plasma, there is nothing to wash, no filters to clean, and an immediate benefit as “hungry oxygen atoms” rip the bad out of the air you breathe.

Is it really effective? Time will tell.

Time Out For Q&A!

For what purpose serves a time delay on an AC unit?

Answer:

When running a single-phase scroll compressor, you may encounter concerns about a pressure-equalization time delay. During off-cycle pressure equalization, scroll compressors spin backwards. Short cycling and energizing a scroll during this time period can cause the unit to continue spinning backwards. Once initiated, this reverse spin will continue until manual ended or the unit trips on internal overloads. Thus may end the life your scroll compressor.

More often than not, a time delay will be linked to anti-short cycling. Short cycling during compressor rush can cause the system to continuously trip a low-pressure safety switch, which in turn can damage the unit. By taking advance of features in a pump down solenoid, some systems isolate refrigerant during off cycling. If the compressor is controlled solely off the LP safety, a faulty LL solenoid can cause pressure to rise in the evaporator during an off cycle. This problem can be present in the recip compressor of an older Liebert Deluxe system.

5 Field Options for Liebert DS Cooling Configurations

1) AIR-COOLED – Liebert DS Cooling Configuration

This process requires piping of field-supplied refrigerant to the condenser. The unit contains a nitrogen holding charge and factory-issued piping is spun closed.

2) GLYCOL-COOLED – Liebert DS Cooling Configuration

Cooling Moments in Air Conditioning Technology

Written by Rm Harrington on . Posted in Air Conditioning Technology, News.

Air Conditioning Technology - Cooling Moments in Hydroceramic Passive CoolingThe History of Air Conditioning Technology Includes A Host of Cooling Moments

Throughout the history of air conditioning technology, “cooling moments” have typically expanded into daily benefits enjoyed by both industrial and residential customers. Let’s hope the new processes defined as Hydroceramic Walls being developed by Catalonia Barcelona expands into another energy-saving cooling technology.

Face it: this nation relies on the power and efficiency of HVAC technology. Keeping up with the demand for increased A/C performance generates a major burden on the environment and the economy. Anytime advancements in cooling technology can boost comfort and production at a reduced cost, society reaps a new blessing.

Herein are the details on new entry into the hall of fame for “cooling moments” in Air Conditioning technology.

Cooling Moments – When Hydroceramic Walls Sweat Like Human Skin

It comes from the minds of researchers at the Institute for Advanced Architecture of Catalonia Barcelona, and according to the students it effectively lowers room temperatures by as much as five degrees Celsius. By taking advantage of the properties associated with evaporating water, the material basically “sweats” away heat. In concept, buildings crafted with hydroceramic walls can effectively remain cooler than a standard building without need of amplified air conditioning technology.

In the order of “cooling moments,” several other methods of passive cooling exist. However, the efficiency of hydroceramic walls may stand out as a modern age wonder for simplicity, effectiveness, and efficiency from a material that features a “cheap” overhead.

Hydroceramic Material – Reduced Energy Consumption

So what defines this breakthrough in “cooling moments” for HVAC technology? According to students at Barcelona, applied hydroceramic material can effectively reduce energy consumption by twenty-eight percent over the design of standard building materials. Furthermore, construction of hydrogels is inexpensive and as simple as sandwiching the materials between ceramic and fabric. The resulting membrane-wall absorbs moisture and then sheds it in a manner similar to how human skin sweats. Thus rather than the occupants of a building sweating, the building itself does the sweating.

The process is really quiet simple: As the material absorbs moisture, the individual hydrogels expand – as much 400 percent. Cooling occurs when evaporation causes the hydrogels to release the water. Thus the polymers shrink, the neighboring area cools down, and the process is ready to begin anew. You might say that it is a process that involves an endless series of “cooling moments.”

IAAC, the Institute for Advanced Architecture of Catalonia

Defined as a center for cutting edge research and education, the IAAC dedicates time, money and training to the development of architecture designs that can effectively meet worldwide challenges for better and more efficient habitability. Although based out of the 22nd district of Barcelona, the IAAC touches the educational services within over 40 countries. Core focus includes building designs, manufacturing functions, ecology, new technologies, energy consumption and reduction, and much more. IAAC research projects expand into a global front, including projects in Brazil, Croatia, and the US.

Will the power of hydroceramic walls actually go down in the history of exciting “cooling moments” in air conditioning technology? Only time will tell. The prototype is still in testing. In theory, the hotter the outdoor wind, the more efficient the system will function. But keep in mind that performance is directly related to evaporation. Thus when evaporation is absent, the cooling effect is also absent.
