I'm sure I asked this before but can't find the thread :-o

I've had a lot of different opinions from different engineers, some aay what I want to do will work, some say it won't work at all

I'm using truck body freezers as blast freezers (with my own equipment on them)

expanding and adding 7 more

I'm trying to get the best out of what I already have / what I buy

I'm thinking about adding heat exchanges to the liquid lines to chill them using a water chiller

water chiller seams the best option here, good second hand units are quite cheap, I appreciate direct cooling via refrigeration would be better but it would be murder to balance the system out if I have 20 separate systems all running at different loads and temperatures

I have an abundance of solar power, so power use / efficiency isn't as important as it normally is


I thought about this originally for summer time high temperatures, but now I'm wondering if it would be better to run year round

I guess my questions are...

is it worth it?
will it work?
how will it effect system capacity?
should I cool before or after the receiver? - liquid line to evaporator is much simpler, but would pre-receiver be better?

looking at the capacity chard of my condensing units, for example...

(404a)

will cooling just the liquid line to the evaporator shift me up the capacity chart?

e.g. -20 evap temp
27'C evap/ambient temp is 7.75kw cooling
43'C evap/ambient temp is 5.80kw cooling

almost 2kw difference... will chilling the liquid line increase system capacity like this?
