Presentation material for supermarket refrigeration
Dear Guys,
I'm compiling some general presentation material for supermarket refrigeration system. Targetted at air cond contractors who are interested into refrigeration market.
Any good suggestion? All I have in mind is
-to discuss on showcase accessories and parts
-how to select a condensing unit, piping design, control & distribution of liquid refrigerant.
-condensing unit or multiset system
-accessories for condensing unit comparing to air cond system
Anyone has done something like that?
Rgds,
Thanks,
Kevin

Re: Presentation material for supermarket refrigeration
Not wanting to open a can of worms but an engineer who has only installed split air conditioners is not a lot of use on the varied range of commercial & industrial refrigeration systems out there, the two fields are totally different, a refrigeration engineer can switch over from fridge to air con no problem (perhaps a little more research & training on VRV's) what you should be doing is offering actual refrigeration training. My views are my own only and as experienced during my spells as service manager, contracts manager and engineering manager and with working with a lot of engineers of varying ability during the last 27 years.

Re: Presentation material for supermarket refrigeration
Check out Copelands site. They have just released new marketing targeting supermarket and food service customers. This is good information to get you familiar with the supermarket products. I will agree that it is DEFINATEY a different breed than A/C. Mess one of these up and you will be buying a lot of food. Good Luck!

Re: Presentation material for supermarket refrigeration
Dear Kevin,
My experience with A/C contractors doing refrigeration is similar to those of bluzman425 and Andy. I have been on a lot of jobs where A/C people (at least the ones I have been exposed to) do not understand refrigeration.
This is not to say all A/C people fall into this category, but I do agree with Andy's comments. It is easier for a refrigeration tech to switch between high, medium, and low temperature applications, than it is for most A/C people to switch from high temp to anything else.
If your interest is in selling refrigeration equipment to other contractors, be prepared to answer a lot of questions and project visits.
My opinion only, but also based on over 35 years plus. I would highly recommend the refrigeration training classes first.
Best Regards,
US Iceman

Dear Bluzman,
I'm just wondering if i can get the URL from you regarding refrigeration material from Copeland.
Thanks,

Re: Presentation material for supermarket refrigeration
Kevin, try to focus on the installation and the commissioning of the refrigeration system and make it the same or easier than the A/C system. The main issue to the contractors is to install and commission the units quickly and thoroughly without facing any problems.
By the way, usually if the A/C people good in understanding how the A/C unit works they would be good also in understanding how the refrigeration unit works. The only difference is that what pressure and temperature the system will works at.

Re: Presentation material for supermarket refrigeration
no offence to air conditioning engineers but you can teach joe bloggs in a day how to install a split type air conditioner and to understand how it operates,
We air condition 2000 seat bingo halls to achieve 21C at table top height - you can't do this with splits. What about air change rates? smoke extraction? these all have an effect on load. What about the 2000 seat club being only part full? this also has an effect on load.
There is much more to air conditioning than fitting splits

Re: Presentation material for supermarket refrigeration
Dear All,
I am not trying to compare between Air conditioning and refrigeration engineers! Both are good. I am trying to give advice to Kevin that some contactors will be understanding refrigeration in a pretty good level so he wouldn't surprise if one ask him a smart question.
Anyway, I have mention that it seems Andy does not has pretty good idea about air conditioning field. All things he has mentioned apply to the A/C units, for intance, in heat pump units we use all types of defrost controllers, oil separators, pressure regulators...etc.
Andy, A/C field is not only mini-split units!

Re: Presentation material for supermarket refrigeration
Dear sir
I think the diff between AC and refrigeration guy is not due to the principle but its application area. My education is mainly focused on refrigeration. I can understand compressor \condenser\evaporator\TXV etc well, but feel hard to use psychrometric chart. AC guy is more keen at air paremeters and refrigeration guy is more keen at refrigerant. Of course,you can be good at both field if you spend enough time and work experience,but I think it's unnecessary

Re: Presentation material for supermarket refrigeration
The man who wants to learn refrigeration will at the end bee good.The one who wants money from refrigeration will blow up things.So it is mater of mind and love to that kind of work.

Re: Presentation material for supermarket refrigeration
This thread is turning into the time old question who is better a/c or fridge engineer, it doesn't matter what you think about each other we all do our days work for a days pay. If you don't like a/c you do fridge and vice a versa.
I am biased from my previous postings the fridge guy understands what the refrigerent is doing and where, but that comment is directed at the split guys and i do understand that proper air conditioning and not just comfort cooling are completely different area's of the trade.
carrying on with the question who is best will turn you all into angry engineers.
Kind regards
Lrac

Re: Presentation material for supermarket refrigeration
I tried the copeland site for the supermarket referigeration but could not get anything.
Would anyone please provide me the link so that I could get the details.
Is there anything else available where from I could get the details.
