Analysis of the Causes of Poor Refrigeration in Explosion-Proof Air Conditioners

Addressing the inadequate cooling of explosion-proof air conditioners requires a thorough analysis of the causes and the development of strategies for resolution. Explosion-proof air conditioners utilize several cooling methods, with vapor compression refrigeration being the prevalent one. This method, which achieves cooling through liquid evaporation, relies on four main components: a compressor, condenser, throttling device, and evaporator.

Technicians often diagnose various faults in explosion-proof air conditioners based on their experience. However, numerous issues can cause inadequate cooling, necessitating the identification of the underlying causes for effective troubleshooting.

The refrigeration cycle’s effectiveness hinges on the refrigerant state changes within a closed system comprising compression, condensation, throttling, and evaporation processes. Identifying shifts in the refrigerant state is crucial for pinpointing the root cause of cooling inefficiency and establishing reliable fault resolution methods.

Poor cooling can arise from several factors, generally categorized into internal and external aspects. External factors encompass environmental conditions and the machinery, while internal factors primarily involve the refrigerant. Comprehensive diagnostics, including observing operational conditions, sound, temperature, and electrical current, are essential for optimal maintenance outcomes. Monitoring condensation, frosting, and the discharge of condensed water provides insights into the refrigerant’s sufficiency, informing troubleshooting and repair strategies based on the vapor cycle refrigeration principles and refrigerant state changes.
