<p>Multi-unit air conditioner and method for controlling the same, the multi-unit air conditioner including a plurality of outdoor heat exchangers 2, a plurality of outdoor fans 15 for cooling the outdoor heat exchangers 2, and control means 9 for controlling rotation speeds of the outdoor fans 15, to control a gas/liquid refrigerant mixing ratio introduced into the gas-liquid separator 10 through the outdoor heat exchangers 2, thereby optimizing the mixing ratio of the refrigerant introduced to a gas-liquid separator 10 proper to an operation condition, for improving an air conditioning efficiency. The control means include a temperature sensor 9 for measuring a temperature of refrigerant introduced from the outdoor heat exchangers 2 into the gas-liquid separator 10, and a microcomputer for comparing a refrigerant temperature measured with the temperature sensor 9 and a preset refrigerant temperature, to detect a refrigerant mixing ratio at the outdoor unit piping system, and controlling rotation speeds of the outdoor fans 5 so that detected refrigerant mixing ratios are the same with refrigerant mixing ratios preset to be proper to operation conditions, respectively. <IMAGE></p> |
