COOLFREE, a brand under Midea Group focused on more comfortable and energy-efficient air conditioners, was established in 2017. It primarily targets ambitious, self-fulfilling young consumers.
With the brand proposition "Freedom in Every Degree," COOLFREE advocates for individuals to live authentically, freely, and comfortably, easily enjoying their desired living temperature. The brand conveys values of "Vitality, Ease, and Focus" through its products. Through stringent quality standards, user-centric design, smart products, and thoughtful services, COOLFREE provides a fashionable and comfortable new living space for the new generation who prioritize quality of life and personal enjoyment.
While the traditional air conditioning industry remained stuck in expensive, bulky, and energy-consuming patterns, COOLFREE keenly recognized the different needs of new consumer groups and decided to make a change—helping young consumers find their own "wind" with new products, new styles, and new concepts.
In 2017, the COOLFREE brand was established. From 2017 to 2024, COOLFREE focused on residential central air conditioning. In 2025, COOLFREE officially entered the household split air conditioner market, launching the COOLFREE KFR-35GW/KF1-P1 model. This unit features core technologies such as High-Frequency Rapid Cooling/Heating, a robust outdoor unit, Cool Power-Saving Technology, Anti-Direct Blow, and Intelligent Self-Cleaning. This new first-grade energy efficiency air conditioner boasts an APF of up to 5.30, offering both energy savings and comfort.
1 . High-Frequency Rapid Cooling/Heating Technology
①Patent Achievements
Won the China Patent Gold Award (Patent No. ZL201310199863.1). Core technologies include Dual-mode Flux Linkage Observation Algorithm and Two-dimensional Anti-Saturation Vector Control Algorithm.
Received the National Science and Technology Progress Second Prize. Core technology is the Compressor Low-Frequency Vibration Suppression Algorithm.
Midea Group's "High-Frequency Rapid Cooling/Heating" technology demonstrates outstanding strength, having won both the China Patent Gold Award and the National Science and Technology Progress Second Prize.
②Electrical Hardware
Utilizes Dual-mode Flux Linkage Observation Algorithm and Two-dimensional Anti-Saturation Vector Control Algorithm to create a high-frequency startup control system for rapid compressor frequency escalation. Frequency transition rate reaches 9Hz/s, a 9x improvement, achieving the industry's fastest heating and cooling speeds.
③Electrical Software
a. Thousands of performance tests determine optimal control parameters for more stable operation and consistent temperature all night.
b. Precise 0.1Hz compressor frequency adjustment for more accurate temperature control.
c. Load prediction-based energy-saving technology across a wide temperature range (16°C–30°C), ensuring more energy-efficient and comfortable operation.
d. Coordinated fan-frequency control effectively avoids "high frequency, low airflow," enabling higher energy efficiency and uniform indoor temperature distribution.
2 . COOL Power-Saving Algorithm
The COOL Power-Saving Algorithm features three core strengths: superior learning capability, computational power, and adaptability. Leveraging Midea Group's massive big data processing capabilities, it deeply learns user preferences, becoming more energy-efficient with use. AI algorithms dynamically predict indoor temperature changes and perform real-time temperature adjustments, ensuring comfort while enhancing energy savings. It also supports an AI Adaptive Mode, offering 24/7 power savings regardless of duration, temperature setting, or weather conditions (rain or shine).
The COOLFREE "Powerhouse" Split Unit is a high-performance unit delivering rapid cooling/heating and energy savings. It aims to provide users with fast, uniform temperature experiences while ensuring long-term energy efficiency and health benefits.
