Introduction
The 802 unit is constructed from components that are required to install a 2.54 cubic metre (75 cubic feet) chill room operating at. -1/+2ºC (30/25ºF.)
This unit quickly enables the student engineer to learn how the basic principles of the VapourCompression Cycle, are applied in practical refrigeration, and provides valuable ‘Hands-On’ experience in:
Fault diagnosis and correction
Refrigerant recovery and recycling
Changing components
Evacuation and Charging
Electrical work
All exercises with the 802 relate directly to installations that students will encounter later in their work as a service and installation engineers.
Description
Model 802 is one of a range of trainers designed to provide practical training in the fields of Refrigeration and Air Conditioning.
Each trainer has been carefully designed to provide instruction in specific topic areas that trainees are required to study as part of most Refrigeration and Air Conditioning courses.
The unit is mounted on a steel frame with stainless steel panels and comprises an hermetic type compressor, air cooled condenser and a forced air evaporator inside an insulated cabinet.
The layout of the system components is exactly the same as fitted to a full size chill room and the unit is designed as an introduction to “real” refrigeration systems. The training objectives of the 802 link directly to the Basic Installation Training Package 803 for a comprehensive range of practical skills training.
A comparison between the student built 803 and 802 clearly establishes whether installation skill and competences are sufficiently developed or if further training and practice are required. A standard Student Tool Kit, Test and Service Equipment Package and Maintenance and Student Practice Package are available as optional items.
