Experimental Analysis of the Influence of the Opening and Closing Behavior of Building Doors and Windows on the Refrigeration Characteristics of Single Air Conditioner

Abstract

The opening and closing behavior of building doors and windows and the setting of cooling temperature have a key impact on the operation and cooling effect of indoor air conditioning. Using the method of field measurement and single factor analysis, the design collected and analyzed the impact and response of the opening and closing behavior of the building doors and windows, the setting of the air conditioning cooling temperature on the indoor environmental parameters, THI(temperature-humidity index) and the power consumption of the air conditioning, and analyzed the dynamic relationship between the use behavior, human comfort and power consumption. The experimental results show that the higher the airtightness of doors and windows of the building and the lower the refrigeration temperature setting of the air conditioner, the smaller the maximum active power value of the air conditioner operation. In addition, closing the doors and windows and raising the cooling temperature setting of the air conditioner can reduce the working time of the air conditioner cooling, especially when the cooling temperature of the air conditioner is higher than 26 °C. There is a significant negative correlation between air-conditioning cooling power consumption and air-conditioning cooling temperature setting and indoor THI index, and the correlation between power consumption and THI index is higher. It is an effective means to effectively improve indoor comfort, energy conservation and consumption reduction to avoid the simultaneous opening of building doors and windows.
