This Haier series (HSU-10VQB22, HSU-13VQB22, and HSU-19VQB23) offers inverter air conditioners with capacities ranging from 1.0HP to 2.0HP. These units utilize R32 refrigerant, known for its lower environmental impact compared to older refrigerants. The inverter technology ensures energy-efficient cooling by adjusting the compressor speed based on the cooling demand. This results in reduced energy consumption and more consistent temperature control. Designed for residential or small commercial spaces, these models provide cooling solutions while prioritizing energy savings and environmental friendliness.
