B

As the summer comes, the exhausted consumers start paying attention to the latest cooling devices(仪器)in the market. With the competition rising ,buying an air conditioner (AC) is no longer a big deal; moreover the easy finance schemes make it a device for every life.

Design

Though it carries the standard design for AC, yet it looks elegant(优雅的) when fixed on your wall. As AC is exposed to exterior(外部的)climate, it is bound to get damaged and bring maintenance cost if not taken proper care of. But Haier has solved this problem by providing an anti-corrosion(抗腐蚀的)body to all its AC. It has a remote control which provides you with ultimate flexibility and you can operate it from every corner of your room.

Key Features

It’s proved that this AC steals the show by offering 1tonne cooling capacity at the EER of 9.47. This means it operates at low power and thus helps you save great energy, and consequently it wins popularity with customers. The rotary compressor(旋转式压缩机)is the secret behind its smooth and silent operation, which makes it suitable for public and silent areas.

Core Information

Advantages and Disadvantages

When compared to other famous brands such as Samsung, Onida, and LG, it offers great functions at a very friendly price. However, it lacks some additional filters which are seen in other expensive brands like Electrolux EA12SCRLA1.
