The main composition of KR-201 is a real window type air conditioner just like in our daily life. What makes it special is that students are able to observe the operation of the internal components and the state of the refrigerant while the air conditioner is running.
From the front panel, there are four refrigerant sight glasses, which provide students an excellent opportunity to observe the state of the refrigerant before and after passing through four major elements Compressor, Condenser, Capillary Tube, and evaporator.
Students can also use built-in gauges/meters to draw the Mollier diagram and so as to understand the performance of this air conditioner. Combining the observation of refrigerant state during different phase of the refrigeration cycle, KR-201 helps students to understand the operating principle of the window type air conditioner easier and faster.
