Abstract:
Electrical safety research in industrial chiller plants using ammonia as a refrigerant. To analyze the safety
of the plant's electrical system and evaluating the safety of the electrical systems of factories in the business
group Cold storage factory, Ice plant, Frozen food factory the use of ammonia as a refrigerant in the production
and storage activities by performing data analysis with the general status of the machinery. And factory
personnel who surveyed the safety of the electrical systemn in the factory related to the refrigeration systemn
using ammonia as the refrigerant of satisfaction in various areas using percentage and standard deviation.
Including opinions related to factors contributing to the research. The results of data analysis showed that
the satisfaction of the electrical system operators to the factory electrical system safety. Environment,
engine room, cooling system and the surrounding area has a high level of safety the electrical system in the
control room and the refrigeration system is of a very safe level. Personnel and electrical hazard prevention
of all types of plants are of a very high level of safety. And the satisfaction of the frozen food factory group
was in the highest criteria in all aspects when compared between the cold storage factory. And an
icehouse at a high level but with a lower average Depending on the electrical design Factory condition
Service life and personnel, which results in satisfaction the main factor contributing to the safety of electrical
systems in the refrigeration industry is more efficient. Depending on legal operations Control of machinery,
equipment and protection in various areas to ensure adequate safety."
