NEXT-GENERATION GAS DRIVEN AIR CONDITIONING SYSTEM UNDER THE CONDITION OF THE HIGHER SETTING TEMPERATURE OF THE ROOM IN THE COOLING MODE AND HIGHER VENTILATION

摘要

In this paper, new air conditioning system in which only one desiccant rotor is connected to the vapor compression type refrigerator that is driven by the gas engine is suggested. And the performance of this system is evaluated by the simulation. The feasibility of this suggested system is as follows. (1) This system is so simple one that is a composed of the vapor compression type refrigerator and only one desiccant rotor. (2) The vapor compression type refrigerator only cools the sensible heat and needs not dehumidifying the air so that COP is enhanced greatly by increasing the evaporating temperature. (3) Two-stage regeneration is carried out. From this, the regeneration temperature of the desiccant rotor can be decreased greatly. As a result, the regeneration temperature of the desiccant rotor is only about 40℃ at the condition of the room air temperature 28℃. And COP of this system is about 20% higher than that of the conventional compression type refrigerator.
