World’s First Co2 Refrigeration Interactive Course

This CO2Refrigeration course provides a broad introduction to the fundamental knowledge required to work on CO2 systems and also helps prepare the student for further study of advanced CO2 Refrigeration Systems.

The course covers design, installation and maintenance considerations, including advantages in using CO2, and functionality of the different refrigeration systems, including volatile secondary, volatile secondary with DX, volatile secondary/cascade, trans-critical and direct expansion. This will be of great assistance to those already working with CO2 and those about to use these systems.

Interest in Carbon Dioxide technology has rapidly grown in the last few years as it provides exceptionally high refrigeration capacities for compressor size while CO2 itself is ozone friendly and has a low global warming potential (GWP) of 1. Regulations have further restricted the use of CFC and HFC refrigerants due to their damaging effect on the environment and the Industry believes that Carbon Dioxide technology will become even more important in the near future.

Star Refrigeration’s experienced engineers have developed this Carbon Dioxide course. The information about the use of CO2 in refrigeration systems was collected from many sources around the world and put together into a superior two-module course, including CO2 Fundamentals  and CO2 Refrigeration System Basics. Danfoss has also contributed to the development of the course by providing valuable learning material.

Star Refrigeration has been working on the development of CO2 technologies and solutions that reduce users’ environmental impact and running costs for more than 15 years. It has, over the years, collected many awards for pioneering environmentally friendlier technologies.

Star has played a leading role in the development of carbon dioxide refrigeration in the UK and overseas. Andy Pearson, MD –Contracts of Star Refrigeration is also co-founder and chairman of The carbon dioxide interest group (c-dig). This group was formed in Europe in July 2000 to provide a platform for the exchange of news, ideas, information and experiences between refrigeration engineers in industry and research/teaching organisations.

All this knowledge and shared experiences in the use of CO2 has been brought together to create this ground-breaking course, providing very clear and useful information about the use of CO2 as a refrigerant. Students achieving an 80% or more in the final test will receive a Diploma certified by CIBSE and the Construction CPD International Service.

Currently, counts with a student community of more than 2000 members.

The Chartered Institution of Building Services Engineers and The Construction CPD Service have accredited this Carbon Dioxide course, which is already being successfully used in the training of major UK’s supermarket service contractors as part of their training programme.

Where To Find The Best Hvac Schools

There are few industries that can stand up to huge economic decline. HVAC and Refrigeration is one of them. This unique career field is commonly called “Refrigeration and Air Conditioning.” Statistics indicate that HVAC sector is one of the most preferred for the job seekers worldwide. It’s no wonder that HVAC training schools have gained popularity.

With hundreds of HVAC schools in Arizona, getting certified may seem not to be a big deal at all. Unfortunately, all these Arizona HVAC schools are not created equal. Future career opportunities for depend upon which school you pick. It is very important to do your homework and make sure that you choose an HVAC school that will give you the kind of training that employers are really seeking.

There are lots of Refrigeration, heating and cooling schools available in the Scottsdale, Tempe and Mesa areas. As already said, not all the HVAC schools in these areas offer good quality training in the sophisticated technology now available.

A common problem found with most of the HVAC schools is that the classes are conducted by fresh HVAC graduates. Their inexperience in the filed of HVAC technologies are reflected on the candidates getting trained by them. The candidates will not be able to deal- with the complications arising in the sophisticated HVAC technology in the real world. Hence it is very important to choose the HVAC Schools with experienced lecturers.

Apart from the experienced staff, good lab facilities for practical lessons in HVAC systems are essential. Job skills in HVAC and Refrigeration maintenance will grow based on the hands-on practical sessions even more than the theory classes. You should make sure that the HVAC School that you choose has the most advanced systems available for training purposes. Most of the HVAC Schools in the Arizona area will not have such systems for practical sessions as these systems are very costly. Remember the fact that the practical sessions in HVAC training are the level deciding factors in your career.

Some of the best Heating, Cooling and Refrigeration schools of Arizona offer financial aid for the training. Moreover, the placement assistance offered by these schools will help you to get into the very best career as soon as you complete the degree. This way, you don’t have to wait for the best career opportunity to appear. Instead, the best HVAC career be available t you based on the good name of the school you got your degree and certification from.

Though there are lots of air conditioning and refrigeration schools in all parts of Arizona, most of them a not easy to spot and are not easily accessible. Only a few HVAC schools like “Refrigeration School” are easily accessible all parts of Arizona. “Refrigeration School” also has a team of well experienced staff. They provide great financial assistance and an excellent job placement staff. Joining this kind of HVAC school will prepare you to become a the kind of person that employers are really seeking.

The Refrigeration School, Inc. offers comprehensive career training through refrigeration, Arizona HVAC Training Program and AZ AC Program classes for a successful career in the HVAC industry.

Refrigerants vs Refrigeration

I continue to get the occasional question, worded something like, “..Hey, do them videos tell ya’ how to charge 410A systems?” And I go into an explanation about the DVD’s covering a review of refrigeration principles with R-22 and providing some discussion relative to 410A…or sometimes I just direct them here and suggest they may get their answer for the price of a websurf…

But, the question still takes me back a little, simply  because I get the impression some people have never heard of any refrigerant other than R22, or never seen a refrigeration system containing any other  refrigerant…I admit, I found out about the pressure thing with 410A indirectly from another tech, who had stumbled onto a R-410A system accidentally, with no knowledge of the refrigerant’s characteristics, and didn’t have a saturated pressure/temp chart for the alien chemical. All he knew was the suction pressure was near double what he was accustomed to seeing. He had the presence of mind to call someone who was familiar, and was quickly tutored as to what he was looking at.

But, if someone out there knows 410A exist, knows the saturated pressures are different, can get his hands on a P-T chart and is comfortable with the application of mechanical refrigeration principles, the question of how to deal with the system relative to it’s type of refrigerant, should be a no-brainer…or not even exist. It’s just another heat pump with another refrigerant…what’s not to understand?
