What is DX-PVT System
A Direct Expansion (DX) PVT system integrates the solar collector directly into the refrigerant loop of the heat pump.
👉 No secondary fluid
👉 No intermediate heat exchanger
Result:
- Higher evaporating temperature
- Improved system efficiency
Key Advantages & Engineering Challenges
