Unit coolers using glycol

[tjk2007]

Dear All,

I need some details to my design.

Plant : Vegetables.
Refrigerant Ammonia
Secondary Coolant:38% Prop. Glycol.

The temp.for the rooms are as follows.

Raw Goods Vegtables Mixed: 4ºC

Cleaning & Sorting 4ºC

Processing 15ºC

Cleaning of dirty crates 22ºC

Finished Goods 0ºC

The above said are customer requirements. We cannot change.

Basically I consider the Room temp 0ºC and take the glycol temp. as follows

Temp in to the unit coolers: -14ºC
Temp Out from the unit coolers:-7ºC

My Question is

• Is it possible to attain the room temp 22ºC in the same temperature program.
• If not what is the solution for that.

Hope I will get some details.



Regards,

Can you include a condenser coil in the 22°C room to provide heating?

What is the ambient air temperature in your region? Can ambient air be used for heating?

Remember Relative Humidity is important. The same should be 80 to 85%.

Ambient Temp:53 C

The Condenser Coil is placed outside of the cold room only.ambient air be cannot be used for heating.Because The ambieent temp & RH are varying suddenly
