METHOD FOR POSITIONING AN AIR OUTLET OF A VEHICLE AIR CONDITIONER AND THE VEHICLE AIR CONDITIONER USING THE SAME, CAPABLE OF IMPLEMENTING AN OPTIMAL VEHICLE INDOOR ENVIRONMENT BY PERFORMING A CONSTANT HUMIDITY MAINTAINING FUNCTION THROUGH SENSING HUMIDITY

摘要

PURPOSE: A method for positioning an air outlet of a vehicle air conditioner is provided to install an air outlet at an optimal position through an air flow analysis using a computational fluid dynamics simulation, thereby improving cooling-and-heating efficiency and maximizing the thermal comfort for passengers.;CONSTITUTION: An optimal position of the air outlet is set through an air flow analysis using a computational fluid dynamics (CFD) simulation with consideration for cooling-and-heating efficiency and the thermal comfort for passengers. A method for positioning an air outlet of a vehicle air conditioner includes the following steps of: installing temperature and humidity sensors inside a vehicle indoor space (S10); performing a numerical analysis using CFD in respect to the sensed temperature and humidity by the temperature and humidity sensors (S20); performing a numerical analysis while changing an air discharging angle, the air discharging speed, and a discharge rate of the air outlet of the air conditioner (S30); analyzing the data in respect to the temperature, the humidity, and the current distribution (S40); and positioning the air outlet at the optimal position with consideration for the cooling-and-heating efficiency and the thermal comfort for passengers (S60).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) Finish; (S10) Install temperature and humidity sensors; (S20) Perform a numerical analysis using CFD; (S30) Perform the numerical analysis while changing an air discharging angle, the air discharging speed, and a discharge rate; (S40) Analyze data in respect to the temperature, the humidity, and the current distribution; (S50) Set an optimal position of an air outlet with consideration for the cooling-and-heating efficiency and the thermal comfort for passengers
