I have a problem
I have purchased a unit condenser
In order to change my unit condenser damaged in cooler milk
I want to make sure a good choice
I think that a very small condenser

In my country there is problem the lack of cooling materials

So by the look of things your unit will provide 1.6kW @ an ambient temp of 42ºC and an evaporator temp of 0ºC.
Is this the duty you are looking for in your milk cooler? If it is then it should work but if not then it won't work...

Is it a good choice?
Well here in EU anything running on R22 is a bad choice as it has been banned due to environmental issues, other than that... We just can't tell.
It is a bit like you asking us if a Bridgestone Battlax BT 014 is a good tyre choice but not telling us anything about the vehicle it is to be fitted to apart from that it will be running on tarmac roads.

Sorry

Why would you replace that?

Great low rpm compressor that can be repaired using standard parts from any workshop.
If it cuts out on HP in the summer then just replace the condenser with a larger one.

Maybe the motor overheats. Missing motor cowl.

its R12 Unite
All R12 Now Its made by China its Rare and causes a lot of problems
And reduces the cooling capacity its Slow
:o
Bro Tell Me If That Compresor Tag 4561 t And Condenser GMK 25.451 Are compatible ؟

bro its not 1600
its 16000 w :confused: sorry

Eh? A 16 KW. I doubt that figure is right as your photo of the "Bitzer" compressor looks too small for 16 KW.
What is the volume of milk you are chilling?

bulk tank of Milk its Old System the compressor Make Ice Water And the ice water chill the milk
Its 4400 liter Packo
No I Say The Compressor Capacity Cooling In Temp Condenser 45c And 7c in Evaporation Its Give me 16000 Watt
My Question
The Compressor And The Condenser Are compatible ?

If your original condensing unit has produced enough ice between milking's, then we need to know the actual cooling capacity of that unit. What is the compressor model number. A Bitzer iv as in Bitzer 4? What speed does the compressor run at.
How many litres/ gallons of milk do you chill per milking?
Your other pictures only show a condenser and 2 compressors. Where is the rest of it?

its bitzer open type reciprocating compressor unit number v
its work now in min Speed Displacement 18 m3/h
Refr R12
in bank tank 4400 liter of Milk
all milk come in 35c go to precooking out 12 Or 13 C And Go to the bank tank But Its Come 4 batches every hour 1000 liter

You see in the image one Compressor The Other is liquid receiver
its not unite Just i am I bought a compressor and condenser of the workshop to assembling
:(
becoz The farm need cooling quickly
before Lost the milk
You Know that
moment !!

Working backwards,18 m3/h flow on R134a, at 40 degrees condensing, and -5 degrees SST roughly equals 6.4 KW.
I don't have data on R12 but R134a should be close enough.

Yeah Its Almost but My New Compressor capacity bigger than the old
:)
Were assembled the unit :cool:
I will install it tomorrow
I am afraid of high pressure
* Performance of the condenser!!! :confused: One fan and little an area of ​​exchange
Fan speed 1250 t/minute
After the unit is installed and tested
the unit will renovate the old
New motor and condenser New
And examination of Pistone and the rest of the parts :cool:
Tell me your opinion
It's important to me ؟;)

5Hp sounds about right to me, don't know about the condenser, it looks like it should work is all i can say!
As a rule of thumb its around 1hp per 200 gallons for ice bank tanks.
I know Serap run their R22 stuff with around 440psi high pressure cut out for tropical environments.

Yes, it's 5 hp
Thank you for rule
In cooling milk there are a lot of problems
In tropical areas

But Im Us Pre Cooling The Milk Go To The Tank 11 Or 12 And 4 Time 1000 Liter Every Hour
But Thank You :)

You are going to use R22 instead of R12 right?
R22 runs at a much higher pressure and your new compressor will need adequate cooling to keep your discharge temperature and pressure low. You have to change the expansion valve and the orifice that feeds the ice bank to a type made for R22.
As your ambient temperature is over 40 C, there is a chance your condenser might not be big enough to remove enough heat and you are left with a liquid/ vapour mix at a high pressure and temperature as the refrigerant leaves the condenser.
This has several follow on effects but you can slow down the refrigerant flow with a CPR valve. (Compressor pressure Regulator.)..... "Crankcase pressure regulator" for you guys looking to correct me.:cool:

Ouch!! 440 PSI on R22 converts to something higher than 65 C. :)

Op could use an EPR but that depends on the number of individual circuits running through his ice bank.

Yeah I prepare One EXV TEX2 With orifice 05
For The New Unite :eek:
R22 Is Much High Temperature But Small Compressor And Pipe AND More Efficacy
Capacity Cooling Is Biger Than R12 Or 134A


yeah Bro Its Clear :rolleyes:
crankcase pressure regulator limits compressor
operation and start-up if the suction
pressure becomes too high. But If Pressure Too Low = More Compression Work And Low High Pressur !! Its True Or Incorrect ؟;) Its Help
And EPR : to modulate the pressure in the evap based on the load and keep the evap pressures above the freezing point
I think a im Need To instal KVR condensing pressure regulator To Separate The Vapor in Outlet Of The Condenser (Vapor In The Receiver Go To Compressor Inlet )
correct me Bro :)
I think A I'm Wrong Like Every Time ;)!!
But The Summer Her Just Tow Months And Some Day 34C or 36C
Rarely Temp Go To 42C
Time To Chill Milk Is in Mourning And Evening
Milk Most Be Cool Before Noon

Specifications on your condenser show 2 possibilities so i'll go with the smaller one that's rated at 10.3 KW.
It seems rather small for 10.3 KW but it does have significant depth.
A CPR is mainly used on freezer rooms to limit the start up load after defrost. In your case, i was thinking it might have to be used if your suction pressure went beyond say...70 PSI (483 KPA) on start up and caused your compressor and condenser to struggle with that volume at 40 C before the TX throttles back.
It's a different story if you have a flood back at 70 PSI.

Ah, suggesting a hot gas bypass tends to tell me you have an oversized compressor. (KVR?)
Hot gas bypass is a method used to raise the suction pressure and slow liquid refrigerant flow to your ice bank.
Hot Gas bypass also raises compressor temperature and reduces a sealed compressor's life.

Yeah Ma Bro
:)Now
Finishing touches on the installation
Charge the the ***** and will tell you the result :o
Thank you for the explanation to me to support me
God bless you
