Freezers 800 liters put together in a room

[thongtn]

Hi All,

My distributor want to use 24 freezers (800 liters size)to store ice cream and put them together in a room.
My suggestion is build a standard cold room with the same capacity (equal with 24 freezer utilized volumes) but they try to do their way.
My questions is: How to prove my way is better

1. investment cost
2. Any bad impact when we put 24 freezers in a room? how to calculate the heat ejection from condenser unit of each freezer?
3. Operation cost: how to compare COP of each way? Maintenance cost?

Any recommendations would be helpful for me.

Kind regards

Nguyen

I think the capital cost, running cost and also maintenance cost will be quite high. The best thing to build a new walk in freezes is firstly to make a full heat load calculations.once you make that you will relise that it was a stubbed idea to run 24 freezes as a cold store in a room while the heat is being rejected inside the room

Whatever the size of the 24 chillers is will need to be doubled to remove that heat load from the room they are in.

Example: Numbers just for show.

One main freezer room, heat load 100kW
electrical load 50kW

One room with 24 freezers, total heat load 100kW
Electrical load 100kW because he will need another 100kW of cooling to remove the heat from the 24 freezers.

Thanks for your input. Do you have any heat rejected calculation, let say how many percent of total power consumption?
