to turn it into the ejector air conditioning system to validate theoretical results with the experimental study. - Highlights: â€¢ Determination of two-phase ejector dimensions of a bus air-conditioning system. â€¢ Thermodynamic analysis of the two-phase ejector cooling system. â€¢ Experimental study on a midibus
was developed based on numerous experimental test runs at various operating conditions, taking into account energy saving and thermal comfort without sacrificing the proper cycling rate of the system compressor. This paper presents a test method for determination of energy consumption of
operation period. The HVAC unit energy consumption is determined from the unit input power, which is measured under several levels of bus engine speeds and at different levels of testing heat load in the laboratory environment.
