Hi can anybody point me in the right direction for some cheap simulation/training software similar to Kotza's REFRIBASE.
I am a full time first year student studying for the new RVQ in refrigeration at NCN so the cost of the Kotza software is well beyond my budget.
I have tried searching on the net but to no avail.
Does this mean only Kotza produce this type of software???
Thanks for any help you guys can offer.

this one is $800 = £500
that was the cheapest I could find ............ and I am not sure how good it is
Depends on how honest and morale minded you are but you could get a copy of the kotza CD and make friends with some one in the college IT dept say no more. I would not as it is illegal,l so is speeding?
Go here it's very good and reasonable http://www.refrigerationbasics.com/Quote:

WOW thats a bit on the expensive side for me, but I do have the demo cd and as you say it is very good.Quote:

What does the RVQ stand for?Quote:

I've heard of the National Vocational Qualification
When the liquid outlet valve is closed, it is quite normal for the HP to increase while compressor pump-down is underway.
True
or
False?
This is one of the questions from the Kotza site - whats your view?
Hi Frank....the RVQ stands for 'Related Vocational Qualification' and is the replacement for the old NVQ.Quote:

The second year can only be completed if you are employed in the refrigeration trade and is on a day release basis where students must complete a portfolio, similar to what was required by the old NVQ.
Hope this answers your question.

On first glance I would say logically that it would be true, you keep pumping the stuff in there and the pressure keeps going up and up.Quote:

Am I correct??

Hi Morph,
Yes you are right, but not completely.
When the pressure starts to drop on the suction side, no more heat is rejected, the fans still working, so temp and pressure start to drop, not much though.

Good answer Chemi but I think the question only relates to a properly charged system and is mis-leading.
consider the real world where the system may be over charged :)
there are other questions on the web site with likewise mis-leading questions that have more than one answer :rolleyes:

Your new avatar has a picture of an iceberg
Me thinks you are missing England too much !!
No worries, you welcome to come back anytime!!!

ooops...............sorry for detracting from the serious questioning and answer sessions........
I always tend to yawn during these "periods"
Reminds me of my old technical drawing teacher at secondary school.
Anytime, anyone so much as yawned............it was up to the front of the class and was caned. Hes justification that a " yawn" was indicative of non interest in the proceedings of the course
Needless to say, I feared him like the plague.
I will always remember him saying to me, " Abe, when I talk about work, you yawn, " if" I talk about girls, your ears will flap !!!
