Can someone provide me some theoretical questions of the British, Canadian and US exams for refrigeration classes?
Eventually for the different levels if possible.
I need those to show the responsibles here in Belgium that our level, our standards aren't high enough compared to those in other countries.
I had a discussion yesterday evening: I gave the students in November 2006 a task which must me finished last week. So they had +/- 7 months.
Don't forget, this is the 2nd year classes. In Belgium, you have to go 2 years to evening classes , once a week from 06:30 PM till 10 PM.
There are also day schools but the school I'm a teacher is giving this and hundreds of other courses only in evening classes.
I personally found that the final test must represent , must be a reflection from what they saw in 2 years classes.
The task was to calculate a small vegetable and a small meat cool room connected to 1 compressor.
So they had to use an evaporating pressure regulator in case ons shuts down and additional resistances to control the humidity in the cold room.
Then a small freezer to let them think about the technics of a freezer, a small cooler to meet HACCP (50kg/110 lbs meals per batch and 5 batches/day to cool in 90 minutes)
They had to verify also if the owner could freeze 100 kg of goods (meat) during the night (8 hours an brought in fresh) with the compressor the selected.
And a shop with a split airco (+/- 12 kW/41000 BTU) in it.
The had to calculate the freezer completely manually (heat load and tubes ) and select manually the compressor, evaporator and TEV, MV, sight glass, all the components.
Because we leave nowadays in a computer world, all the rest may be done with a computer but they had to insert the print outs.
A small schematic of the lines
I gave them all the internet links they needed to make their final project and all the software was discussed in class.
I think you agree with me that you have to use software regulary to get used with it. But you have to know if they ask in a sofwatre package to enter SH that this isn't a license plate of a car.
We discussed also Coolpack during some hours.
Someone interested in refrigeration and computers will surely experiment with this marvelous piece of software.
Now, the older teachers 'blamed' me that this ways too much to handle in 7 months.
They gave in the past only one room to calculate, mostly a very small freezer room with heating resistances.
I disagreed completely because you have to know that the let pass everyone and that this in Belgium your ticket to start your own business in cooling.
Tehy even don't have to make a practical test.
So someone who's making a beautifull thesis and don't know how to connect a manifold on a compressor will get his ticket.
They will become competitors of my.
Due to my earlier intervention, they now will have to make alsoa final practical test next year and they have to succeed in both, theoretical and practical.
I like to hear your comments on this.
