CO2 heat pump
The refrigeration system adopts R134a/CO2 cascade system, and the recovery of condensation waste heat adopts CO2 transcritical heat pump. The heat source side is the liquid after R134a condensation, which provides subcooling and improves the efficiency of the refrigeration system. The CO2 heat pump raises the 5°C cold water to 75℃ at one time.
Refrigeration system subcooling plate heat exchanger, subcooling heat recovery
Multi-flow plate heat exchanger, one-time high-temperature hot water
