heat exchanger for CO2 heat pump
- participación
Supercritical CO2 HE
Air source heat pump applied CO2 as refrigerant, and get heat from air. Over critical section co2 system heat release temperature is about 80 -100 °C, and it is very suitable for heating water.HZSS CO2 heat pump water heater gas cooler/regenerator can standa high pressure，inner tube material is BFe10-1-1，and the spiral grooves inner tube cab also enhance the heat exchangers ability for pressure standing. Besides BFe10-1-1 material can also be of anticorrosion.
Product Profile: HZSS's self developed supercritical heat exchanger is applied in transcritical carbon dioxide heatpump water heater system.
Product Features:
1. Water in the inner coil and gas in between the inner and outer coil to enhanceturbulence intensity and heat transfer coefficient.
2. Spirally corrugated tubes increase heattransfer surface area to create higherefficiency.
3. Reliable with higher pressure stand and less welding points.
4. Anti-freezing and self cleaning.
5. Cupronickel inner tube gives better compressionperformance and corrosion resistance.
