Air Conditioning System Experimental Equipment
The air conditioning systems widely used in various industries and for improving living standards not only maintain comfort in daily life but also refer to the control of industrial process environments. The air conditioning system experimental device EC1501V demonstrates the cooling and dehumidification processes as well as the thermodynamic processes of refrigeration systems. The tabletop experimental device using R134a as the refrigerant is equipped with an evaporator in the center of the open duct, a fan at the right end, and a disk for flow adjustment. The transparent acrylic plate at the front allows for observation of the internal sensors and evaporator. The temperature of the refrigeration system, the temperature and humidity at the duct's inlet and outlet, and the high and low pressures are digitally displayed on the control panel's LCD display. Additionally, using the included VDAS software, various data can be displayed and collected on a PC (sold separately), and p-h diagrams and psychrometric charts can be drawn.
