AIR CONDITIONING SYSTEM


  1. CONSTRUCTION


    1. A sub-cool accelerator type tube is used to enhance air conditioning cooling performance. The tube functions as a heat exchanger by making use of the temperature difference between the gaseous refrigerant and liquid refrigerant.

    2. The sub-cool accelerator type tube has a double-pipe construction. Helical grooves are embossed into the outer wall of the inner tube. Low-temperature and low-pressure gaseous refrigerant passes through the inner tube. High-temperature and high-pressure liquid refrigerant circulates between the inner tube and outer tube in the gap created by the grooves. Heat exchange occurs due to the temperature difference.

    3. The high-temperature and high-pressure liquid refrigerant circulate along the helical grooves causing the refrigerant to remain in contact with the outer wall of the inner tube for a longer period of time. This achieves an ample exchange of heat.

    4. By lowering the temperature of the refrigerant that has passed through the cooler condenser, more liquid refrigerant is supplied to the evaporator and the evaporator is also kept cooler. This enables an enhanced air conditioning cooling effect.
