i have problems with calculating how much chilling enery we need to chill 10m3 amount of watter.

it is possible to help me someone?

I have compresors with chill power of 30kW. i need to chill water from +1 celsius to -5 degree. ( ice making). Is this enough to chill 10m3 of water?

How much time i need with that power of compressors?

Thanks in advance for your help

### Re: water chilling

You can try with thermal energy calculator.

Here are results that I have with your inputs:

Heater/Chiler calculator

1. mass flow rate (w):

w : 1.1944578 kg/s

2. volumetric flow rate (q):

q : 4.3000445 m3/h

3. density (ρ):

ρ : 1000.0 kg/m3

4. diameter (D):

D : 60 mm

5. velocity (V):

V : 0.422453 m/s

6. specific heat (c):

c : 4186 J/kgK

7. thermal power (P):

P : 30 KW

8. inlet tempearture (T1):

T1 : 1 C

9. outlet tempearture (T2):

T2 : -5 C

It means that with 30 kW chiller power you can change temperature of water from 1 to -5 C with flow of 4,3 m3/h. So for 10 m3 you would need about 2.5 h.
