Why is "CO2" the keyword for KingClima bus air conditioners?

KingClima is the pioneer of heat pump bus air conditioner. In the era of new energy vehicles, with the deepening of automotive thermal management technology research and development, automotive heat pump air conditioning is receiving attention from the whole industry, among which the CO2 heat pump air conditioning system has become one of the main R&D products of KingClima air conditioning in recent years.


 

If you are interested in CO2 heat pump bus air conditioning system, welcome to inquire!

The development process of heat pump air conditioning technology route is to relocate the external low temperature energy (such as air, sun, water, wind, etc.) to the user side (terminal), using the law of energy conversion, through the consumption of power to achieve energy efficiency ratio COP>1.0, which is the foothold and source of heat pump research, how to maximize the energy efficiency ratio is the main subject of the study.
With the continuous development of technical routes and the promotion of environmental regulations such as the Global Climate Convention and the Kigali Amendment, CO2 refrigerant with a global warming potential (i.e. greenhouse effect) of 1 is increasingly becoming the ideal solution for the environmental friendliness and low temperature adaptability of heat pump air conditioning refrigerant.



Characteristics of CO2 refrigerant work substance.
① Natural work substance (ODP=0, GWP=1), good safety, non-toxic, non-combustible.
② Large latent heat of evaporation, high refrigeration capacity per unit volume.
③ Excellent fluidity and heat transfer performance.
④ low filling volume, low shaft power consumption.
⑤ good chemical stability, less relevant chemical reactions.
⑥ Higher operating pressure.
⑦ Low critical point temperature, only 31.1°C.
⑧ TLV safety limit of 5000 PPM (0.5%)



The following are the CO2 gas cooler and evaporator and other core components, respectively.
The natural work substance CO2 is a never-failing refrigerant with a small greenhouse effect coefficient and no damage to the ozone layer. Mastering CO2 cooling technology is crucial for KingClima Air Conditioning to remain advanced and competitive in the industry.
