The A/C Training System with H-Block (TXV) (EM-2000-HB_053094) is a complete air conditioning system trainer designed to enhance the instruction of air conditioning physics. This trainer utilizes the H-Block TXV design for refrigerant flow control and incorporates common automotive components, making it suitable for both classroom and shop environments. It features a hermetically sealed and internally protected compressor and operates on a 120V 15A 60Hz circuit. Students can observe refrigerant state changes through clear sight glasses at the receiver/drier, evaporator, and condenser, while connecting the trainer to any A/C recycling/recovery equipment via R134a service ports. The system allows visual inspection of the H-Block (TXV) and receiver/drier operations, provides pressure and temperature measurements for the evaporator and condenser, and enables the introduction of system restrictions and blockages for diagnostic learning. Adjustable fan speeds demonstrate typical performance issues, and removable magnetic labels aid in component identification and refrigerant flow understanding. Equipped with safety switches and protections, the trainer supports hands-on exploration of abnormal symptoms through adjustable cycling switches and ball valves.
