Abstract

Abstract: Through the questionnaire survey of 746 residential buildings and the on-site survey of 110 residential buildings, the main installation form of the current air conditioner outdoor unit-the groove with louvers and its characteristic dimensions were found. Based on the research results to restore its usage scenarios, in the air-enthalpy difference laboratory, a large number of comparative tests were carried out on a 1 HP room air conditioner using the refrigeration performance test method of GB/T 7725-2004. The results show that the commonly used louver grooves will cause the cooling energy efficiency ratio of air conditioners to be reduced by 36%, and the ventilation dimensions that affect its performance are the front, left, top, rear, and right spacing in order, and there is an optimal value for the spacing of the louver grille which is related to the inclination direction and angle of the grille. On this basis, the recommended value of the minimum ventilation size of the groove space where the cooling energy efficiency ratio of 1 HP air conditioner attenuation is less than 4% is given.

Key words: Room air conditioner, Energy efficiency ratio, Outdoor unit installation platform, Groove, Louver
