cute water cooled plant (56K WARNING)

[Xeon th MG Pony]

here is a small water cooled plant that will run R-134a or R-507 6,000btu.

Assembling it for a comercial kitchen

(Finaly got the cam working)

Looks good, what does the "Head pressure modulated flow valve" do ?

[flesheatinvirus]

It regulates the rate of water flow through the Condenser based on discharge pressure and can be adjusted to raise or lower head pressure by increasing/decreasing spring load compared to current head pressure. Adjustment nut is on the top of the valve.

yup thats what she does and how to use it, minimizes water waste.

[yngndrw]

Ah I see, so the water is an open loop then ? (Otherwise I cannot see how it would minimise water waste.)

Just out of interest, what's the specific application for it ?

I believe it takes tap water to cool the condenser and dumps it down the drain. Correct me if I'm wrong but if that's how it is then damn.. a waste

@ yng: it's for comercial kitchens such as bakeries where the ambient temp is all ways very high.
@ Gomeler: Your weighing the lesser of eviles power consumption and equipment life Vs the .5 to 1 gpm it will use and the reduced power draw and longetivity of equipment life, all so the equipment will remain considerably efficient over time as there is no condensor fan to consume power or fail & there is no fin coil condensor to plug up!

I guess it just matters on the locale. Atlanta has been in a drought for years and I guess I'm focusing less on power consumption and more on water Still very neat, would be even cooler if it had a closed water loop dumping heat outdoors.

I used to own a pizzeria, and I had a big Scotsman air cooled ice maker. It could produce all the ice I needed for a day by running only at night, but it had to run only at night because it was close to the dining room and was too loud (the condenser fan) to run during biz hours. Sometimes someone would forget to switch it on at night, and we'd have to endure it during the day.

Replaced it with a smaller water cooled Hoshizaki (which could run on demand), I got a huge amount of floor space back and didn't have to think about ice anymore.

By removing the control valve it can be attached to a cooling tower system, or the valve replaced by a VG47 series valve and flow balancer.

I've been talking to the resteruant about the possibility in investing in a heat reclaim & closed loop system, but as all ways cost is the highest priority as they're still yung.

Ah I see then, pretty nice system. Would have never thought about using tab water as a coolant like that, but then again it's the same as what we did in school (Chemistry) to distil stuff.
