The odor generated by air conditioners is an important factor influencing the perceived quality in buildings. In this study, different types of and filters were investigated to study level emission related operation state compressor, identify compounds analyze cooling setpoint temperature on emitted intensity. Results show that from constant frequency conditioner use periodic stronger than vari...

Background. Allergic fungal airway diseases, such as asthma and allergic bronchopulmonary mycosis (ABPM), are often difficult to manage with medical treatment alone; therefore, environmental exposure should be accurately evaluated minimized. In the present study, we established a method evaluate eliminate contamination in household air conditioners (ACs). Methods. fall of 2020, an survey living...

As the COVID-19 global pandemic continues to remain severe, people tend spend more time in an indoor dwelling and, much of summer, choose sit at air-conditioned homes, offices, or travel vehicles. In order reduce occurrence health-care-related diseases, cleaning and disinfecting such environment is critical as polluted air posed threat human wellbeing, reduces life expectancy due cardiovascular...

Currently, a majority of global residential air-conditioning requirements are met using cooling systems based on the vapor compression cycle (VCC). To meet future demand for space and to reduce corresponding environmental impact, there is need alternative which require less resources exhibit higher coefficient performance (COP). One proposed alternatives called hybrid evaporative-vapor (HEVC) c...

Modern inverter-based air-conditioners (IACs) are generally equipped with power-electronic components to achieve higher efficiency and more advanced controllability. Thus, their operating behaviours can be very different from the conventional direct motor connections, new characteristics have not been adequately studied in current literature. hardware experiments conducted extract novel dynamic...
