Explore the Safety of Electrical Systems in Factories that are Related to Cooling System that uses Ammonia as a Refrigerant

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 system in the factory related to the refrigeration system 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.
