Chapter 116 - 113: The Longing for Sweet and Sour Pork Ribs
"Simple Ground Source Heat Pump"
"Upgrade Option 1: Replace the circulating medium, improve the heat exchange efficiency of the equipment medium, survival points needed for upgrade: 300"
"Upgrade Option 2: Replace the circulating medium, enhance the circulating efficiency of the equipment medium, survival points needed for upgrade: 500"
The ground source heat pump equipment assembled by Chen Xin was still an ugly thing, but compared to the clutter of items created for the initial oxygen machine, this ground source heat pump at least looked like something decent, not overly crude or shoddy.
Seeing the upgrade options displayed by the system, Chen Xin merely raised an eyebrow and clicked to confirm the upgrades, applying both upgrade options to the ground source heat pump.
A flash of green light passed, and the entire ground source heat pump seemed rejuvenated, with changes in its size and structure.
Overall, the equipment got larger, the pipes thickened, and the structure became more complex.
Or it could be said that what Chen Xin had just made was barely something that could be called a ground source heat pump, and it was only after the upgrade that it became a true ground source heat pump device.
However, looking at the large pile of pipes on the ground, Chen Xin scratched his head. Qin Lan’s drill hadn’t arrived yet. How was he going to install this thing into the ground?
