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
Key Advantages
- ✔️ Maximum thermal efficiency
- ✔️ Reduced system losses
- ✔️ Compact system design
Engineering Challenges
- Refrigerant safety compliance (F-Gas regulations)
- Installation complexity
- Long-term reliability
👉 Compliance note:
System design must follow EU F-Gas and pressure equipment directives.
