Crocodile Project: the First CO2 Transcritical Refrigeration System Implemented in Hot-and-humid region

The Crocodile Project is a system that uses carbon dioxide (CO2) in the air to cool in a closed system. The user can reuse a large amount of heat left over from the cooling system for hot water production, which can be used in buildings that require both "cooling" and "heating" applications such as hotels, shopping malls, hospitals, food factories, for example. 

The Crocodile system is suitable in hot and humid climates countries. This system will work only at night, coupled with Cooling Battery technology during the day, and will reuse all heat energy above 100 degrees Celsius. This makes the system's performance more than twice as good as the normal system. The use of CO2, a substance with a very low GWP value (GWP=1) reduces the burning of fossil fuels, so it will not be toxic to the environment and surrounding communities and also help to reduce global warming at the same time. For business, the utilization of waste heat will help reduce cost; therefore, the Crocodile system is a cooling/air conditioning system that can utilize energy to meet a truly sustainable environment, society, and business.
