Students of refrigeration and air conditioning rarely get to watch a vapour-compression cycle at work, because commercial window units hide every component behind a sealed casing. This paper describes the design of a compact, open-frame window air-conditioner setup built to remedy that for HVAC teaching and laboratory demonstration. The proposed unit contains a hermetic compressor, an air-cooled condenser, an expansion device, an evaporator, an indoor blower, a condenser fan, copper piping, an electrical panel and planned instrumentation, all arranged so that each part can be seen, reached and measured. The arrangement was developed through a literature survey, component selection, three-dimensional CAD modelling and a pre-fabrication review of layout, clearances and expected operating sequence. Temperature, pressure and airflow measurement points are fixed in the design, and space is kept for a later data-acquisition system. A steady-state energy-balance model is presented for computing cooling capacity, compressor work, heat rejection and coefficient of performance once the unit is tested. No measured data or solved state-point values exist at this stage, so the paper makes no numerical performance claims. It offers a reviewed design basis for fabrication, experimental validation and later work on digital monitoring.
KEYWORDS
A compact window air-conditioner setup based on the vapour-compression cycle has been designed and reviewed as a platform for HVAC teaching. Its open layout keeps the compressor, condenser, expansion device, evaporator, fans, piping and instrument points visible and accessible, and CAD modelling allowed placement, clearances and safety to be examined before anything is built. The main contribution at this stage is a design framework and an evaluation method that treat visibility, access and measurability as design goals. Because no measured data or solved state-point values exist, the paper reports no cooling-capacity or COP figures, and those will have to come from the fabricated and tested unit. The setup is intended for laboratory demonstration and experiment and gives a base for fabrication, data acquisition and further study.
