Description & Features
The CO₂ Heat Pump - CEZDD Series is a double-return air overhead unit. This low-temperature CO₂ heat pump A/C is highly suitable for 8-13m buses and long-distance coaches, and it can seamlessly integrate battery cooling functions.
- ✔
More Environmentally Friendly: Adopts natural and environment-friendly CO₂ refrigerant (ODP=0, GWP=1) to strictly meet the requirements of environmental protection regulations. - ✔
Highly Efficient: At -10°C, the heating efficiency is about 30% higher than that of traditional R410a A/C systems. - ✔
More Intelligent: Can be controlled in a safe and efficient manner; the system automatically defrosts and features advanced monitoring and predictive operation/maintenance capabilities. - ✔
More Reliable: A safe and reliable pressure relief valve combined with pressure control is used to realize multi-level protection for system product safety. - ✔
Stronger Environmental Adaptability: Designed to operate reliably in an extreme ambient temperature range of -30°C to 40°C.
