Product Introduction
Cling's CO₂ air conditioning is an ultra-low temperature heat pump product that uses natural refrigerants and can operate stably at -30℃. Compared to the original R410A heat pump products, it increases heat exchange by 91% and energy efficiency ratio by 63% at -20℃. It represents a breakthrough application of CO₂ heat pump technology in the field of bus air conditioning.
Features
Stronger environmental adaptability
Adopts a fully enclosed CO₂ system-specific frequency conversion compressor, suitable for lower ambient temperatures, and can operate within an ambient temperature range of -30℃ to 40℃.
Smarter
Independently developed heat pump air conditioning control system, combined with product features to achieve dual control of efficiency and safety. The system has defrost control and is equipped with monitoring and predictive maintenance capabilities.
More reliable
A safe and reliable pressure relief valve combined with pressure control is used to realize multi-level safety protection for the system.
High environmental protection
Adopts natural and environmentally friendly CO₂ refrigerant (ODP=0, GWP=1), which is safe, non-toxic, and non-flammable.
High efficiency
At an ambient temperature of -10°C, the heating efficiency COP is about 30% higher than that of traditional R410a air conditioner.
High performance
High-pressure resistant heat exchangers matched with reliable evaporative condensing fans improve system efficiency and ensure more stable system operation.
Cling product advantages
Already in mass use in the Netherlands, Italy, and other regions, and has received widespread acclaim from customers.
Cling product advantages
Uses natural and environmentally friendly refrigerants, in compliance with European environmental requirements.
Cling product advantages
High heating efficiency at low temperatures.
- Cooling working principle
-
At cooling mode, the liquid refrigerant absorbs heat and vaporizes, becoming LP, LT steam, and goes into compressor, and gets compressed into HT, HP gas, then moves through 4 way valve, then into condenser to lose heat, it becomes mid pressure, LT liquid, then throttled by expansion valve, loses pressure, then goes into evaporator to vaporize. Such a loop goes on and on.
- Working principle - Heating
-
At heating mode, the compressed HP, HT gas refrigerant goes into bus evaporator to release heat, becoming mid pressure LT liquid, then throttled by expansion valve, becoming LT, LP liquid and vaporizes in the condenser to change into gas refrigerant, and goes into compressor again. The loop continues.
