The Hisense AN10DBG, AN13DBG, and AN20DBG are standard air conditioners available in 1.5HP and 2.0HP models, utilizing R32 refrigerant. These models provide efficient cooling for residential or commercial spaces. The R32 refrigerant is known for its lower global warming potential compared to older refrigerants, making it an environmentally conscious choice. Key features typically include adjustable fan speeds, temperature control, and various operating modes for customized comfort. The 'Standard' designation suggests a focus on reliable performance and essential cooling functionalities, rather than advanced smart features or energy efficiency technologies found in higher-end models.
