Haier Air Conditioners: Comfortable Winter Heating Without Temperature Drops Revolutionizing Winter Heating: Haier Air Conditioners' Innovative Defrosting Technology

The cold and dampness of southern winters often turn air conditioning heating into a "hard nut to crack." Even when heating is on, sudden temperature drops occur during defrosting, making the room temperature fluctuate like a roller coaster. Worse, frequent defrosting can lead to shutdowns, leaving users without heat in the depths of winter and shivering with cold. This is a long-standing industry challenge – the issue of air conditioners frosting quickly, performance dropping suddenly, and temperature fluctuations during defrosting in low-temperature and high-humidity environments. Now, Haier air conditioners have cracked this pain point first.

On July 25, 2025, Haier air conditioners, in collaboration with Beijing Institute of Technology and Xi'an Jiaotong University, developed the "Comfortable Defrosting Technology Based on Variable Module Heat Exchanger" and passed the results evaluation meeting organized by the China Association for the Promotion of Industry-University-Research Cooperation, which ultimately recognized the technology as internationally leading.

The core of this innovative technology lies in three major breakthroughs. Firstly, it proposes an integrated variable module new high-efficiency heat exchanger. It uses specially designed valves and分流 technology to make the refrigerant flow more uniform and stable. This innovation, based on the innovation of variable airflow technology, can defrost quickly without causing indoor temperature fluctuations. Secondly, the "Precise Frost Measurement System" developed through microwave induction technology achieves precise prediction based on the frost layer equivalent thickness. Finally, Haier air conditioners have innovatively invented the heating positive cycle partition rapid defrosting technology to address the problem of fast frosting, sudden performance drop, and high energy consumption in low-temperature and high-humidity conditions of heat pump air conditioners. The air conditioner can quickly remove micro-frost in heating, and also continue to heat during defrosting, shortening defrosting time by 18%.

In practical applications, this technology brings significant experience improvement to users. In the cold and damp southern winter environment, Haier air conditioners can maintain heating temperature fluctuations of no more than 0.5℃, far lower than the industry average of 3℃ fluctuations. At the same time, the 24-hour uninterrupted heating capability allows users to no longer endure the heating interruption caused by traditional air conditioners due to defrosting.

Experts pointed out that this technology has solved the industry challenge of air conditioning heating performance decline in low-temperature and high-humidity environments through integrated innovation, and has reached the international leading level in terms of comfort, energy saving, and reliability. This is not only an acknowledgment of Haier air conditioners' technical strength but also points the direction for the product performance improvement of the entire industry under extreme weather conditions.

Starting from the user's experience and tackling technical difficulties, Haier air conditioners' this innovation has not only passed the authority certification but also redefined the comfort standard for winter air conditioning heating. When "no temperature drop during defrosting, no heating shutdown" goes from expectation to reality, perhaps this is the warmest response of technology to life.
