Laboratory installation for the study of refrigeration machine with automatic control and measurement system (PAHP-HM-SAU)

Designed to obtain practical skills in operation and maintenance of refrigeration plants with the possibility of modelling faults in the supply of refrigerant to the evaporator and in electrical circuits. List of works to be performed on the training stand: - Studying the peculiarities of the device and principle of operation of refrigeration plants. - Building and analysing the operating cycles of refrigeration machines and installations. - Testing of the refrigeration plant in different operating modes. Investigation of the influence of the coolant temperature on the operating parameters of the vapour-compression refrigeration plant. - Studying the device of refrigeration compressors and determining the parameters of the reciprocating compressor. - Familiarisation with the design, purpose and adjustment of automation devices. - Drawing up the electrical circuit of the freon refrigeration plant. Determination of electrical circuit faults
