Educational Advantages

Trainer has all major components required for an automotive air conditioning system using the H-Block TXV system.

Fully operational with typical component layout and organization.

Clear sight glasses provide clear understanding of the H-Block (TXV) air conditioning refrigeration cycle.

Allows student observation of refrigerant changes of state (liquid/vapor) at the receiver/drier, evaporator and condenser.

Trainer can be connected to any A/C Recycling/Recovery equipment using R134a service ports.

Allows visual inspection of the role and operation of the H-Block (TXV) and receiver/drier.

Provides pressure and temperature measurement displays of evaporator and condenser.

Allows the introduction of system restrictions and blockages for diagnostic learning.

Adjustable fan speeds for demonstrations of typical performance problems for evaporator and condenser.

Removable magnetic component identification labels and refrigerant flow arrows for student learning.

Equipped with high pressure cut-out switch, evaporator deicing switch and internal compressor protection.

High and low side ball valves can be adjusted to demonstrate various system restrictions resulting in abnormal operation.

Trainers condenser, evaporator and compressor cycling switches can be adjusted to demonstrate various abnormal symptoms.
