Hi all,
Can anyone help me with these?
1. I need to cool 120.000 liter of water in a pond down to 22°C (initial temperature is 30°C), the pond is in enclosed area. Will 2 x 5pk compressor enough?

2. Another one is water tank with 6.500 liter of water (3.250 liter in the tank and 3.250 liter inside the pipes), initial water temperature is 44°C and plan to keep it stable at 10°C.
Right now they are using six unit of 2pk chiller, but couldn't bring the temperature down to the desired level, only down to 34°C. The water flow is 300 liter/minute.

Thank you all.
