This is an authentic vehicle air conditioning system mounted on a frame for teaching purposes. It teaches the principles of the refrigeration cycle and the function of the component parts of the system. The unit has switchable faults that simulate actual faults found on vehicle air conditioning systems. This unit is charged with R134a non-ozone depleting refrigerant.
Features
- Complies with City & Guilds 2079
- Industrial components
- Portable design
- Open frame allows easy access to all areas
- Incorporating simulated faults
- Comprehensive experiment manual included
The system is an example of a refrigeration circuit from which the basic vapour-compression cycle can be studied. This process entails the circulation of a refrigerant medium that is forced to change state in the evaporator by expansion from a liquid through to a superheated gas. During this phase of change, large amounts of heat energy are absorbed into the refrigerant, which is then pumped round and rejected to atmosphere through the condenser.
Complete with
- compressor,
- condenser,
- receiver dryer,
- thermal expansion valve (TEV) and
- evaporator,
the unit is pre-installed with R134a type refrigerant which is a HFC non-ozone depleting gas and is in line with global emissions guidelines.
The system is furnished with high and low-side pressure service ports that facilitate easy connection of a gauge set* such as 739005 for pressure measurement* or for the recovery and recharging of refrigerant**. These ports are typical quick coupler type as would be found on modern vehicles.
* Possibility of preassure measurement with gauge only! Gauge set not included!
** Observe your local legal requirements for handling refrigerants!
