What cooling effect does this system have?

[TSN79]

Shown in the attachment is a system consisting of a heat pump and other components. My question is how I can approximate the total cooling effect in Watts available to the cooling battery. We know that the ground water is about 5 degrees, and I have some other data as well, just shout as I'm not sure what's relevant. The heat pump has a THR value of 154 kW.

Perhaps I should actually attach the attachment...
