Dear All,
We have an existing refrigeration capacity of 1000KW and now we want to upgrade it to 3000KW with addition of similar compressor. Following are the component data for existing components and components being added.
1- Refrigerant: Ammonia
2- Required Process cooling water temperature: 0-2C
3- GEA V1400 compressor 01 existing; Two more compressors to be added.
4- Condensers: Evaporative condenser 1200KW (wetbulb 28C/conden. Temp 37C/Evaporation Temp: -4C) Same condensers to be added making total 3 condensers
5- HP receiver size: 500mm x 1200mm vertical (will remain same)
6- LP Receiver Size: 1200mm x 3500mm horizontal (will remain same)
7- Expansion Valve: ICS type hand expansion valve (will remain same)
8- Evaporator: Gravity feed 3000KW PHE (03 meter below LP Rec.)
9- Ice water tank size is 20000 liters
10- Piping, we know its OK for pressure drops
My questions are:
1- Are HP & LP receivers of sufficient capacity?
2- How can I check capacity of expansion valve to handle extra flow?
3- Although evaporator is of 3000KW, will it generate sufficient vapors for working of 3 compressors? How can I check?
3-Ice water tank capacity is oK or we need to increase its size? What is criteria of its sizing? How to check for its working for peak conditions?
Regards
