On a scorching summer day, have you ever felt a sudden chill when entering an air-conditioned room, forcing you to wrap yourself in a blanket? During bitter winter cold, have you suffered from dry skin and throat irritation caused by direct hot air? These discomforts, commonly known as “air conditioner sickness,” have long plagued countless households. Today, huawa’s revolutionary product—the coupling-based radiant air conditioning system centered on the “AC companion”—quietly transforms this situation, offering us an unprecedented “imperceptible” comfort experience.

From “Perceptible” to “Imperceptible”: A Quantum Leap in Comfort

Traditional air conditioners rely on forced convection, blowing cold/hot air directly onto the human body, resulting in locally over-cooled or over-heated areas, difficulty maintaining room humidity, and significant temperature fluctuations. Our ABC coupling radiant air conditioning system achieves perfect integration between traditional cooling/heating and floor radiation through the innovative combination of “air conditioner + AC companion.” It transfers cold/hot energy gently into the indoor space via radiation, eliminating the sensation of strong air currents and the annoying noise of traditional air conditioners.

Ms. Wang is among the first users of this system. She tells us: “In the past, during summer with traditional air conditioning, I always had to cover myself with a blanket while watching TV, and my children often caught colds from the AC. Since installing this new air conditioning system with the radiant cooling from the AC companion, the indoor temperature is uniform without perceptible drafts, and my children can play on the floor without catching colds. Most surprisingly, I no longer wake up with a dry mouth and that uncomfortable tight feeling on my skin.”

The AC Companion: The Key to the Comfort Revolution

In this system, the “AC companion” plays an indispensable role. It is not simply a basic auxiliary device but, through ingenious thermodynamic design, optimizes the single-stage heat exchange process of traditional air conditioners into a two-stage serial heat exchange. When the air conditioner operates, the plate heat exchanger and circulation pump inside the AC companion work together to evenly distribute cold/heat through the underground PE pipe network, ensuring a homogeneous temperature throughout the house.

In summer, the air conditioner first absorbs room heat to provide basic cooling, while simultaneously the AC companion utilizes the remaining cooling capacity of the refrigerant to dissipate heat through water circulation to the underground PE pipes, achieving radiant floor cooling. This cooperative “cool above and cool below” operational mode creates a more uniform temperature distribution in the room, avoiding the problem of vertical temperature gradients in traditional air conditioners where the upper area is warm and the lower area is cold.

In winter, the functionality is even more remarkable. When outdoor temperatures suddenly drop below zero, traditional air conditioners often fail, while our air conditioning system together with the AC companion, through a two-stage condensation process, not only improves heating efficiency but also discreetly radiates heat through the floor, creating the healthy temperature gradient of “warm feet, cool head.” This allows you to walk barefoot and feel the warmth of your home even during the coldest seasons.

Health and Energy Efficiency: Dual Added Value

Studies show that human perception of radiant temperature is much stronger than that of air temperature. Our AC companion system is precisely based on this principle—by controlling the temperatures of radiant surfaces, it allows the human body to feel cool at higher air temperatures (summer) or warm at lower air temperatures (winter). This not only significantly improves comfort but also brings important energy savings—the ambient temperature can be set closer to the human comfort range, reducing unnecessary energy consumption.

“Mr. Li from Shanghai shares: “After installing this system, my electricity bill has dropped by about 30% compared to the same period last year. Even more surprisingly, my family’s allergic symptoms have significantly improved. My doctor explained to me that traditional air conditioners easily disperse allergens in the air, while the radiant heat exchange of the AC companion creates almost no air movement, substantially reducing the transmission of allergens.”

Redefining Residential Comfort Standards

Huawa’s coupling-based radiant air conditioning system is far more than just a technological innovation—it redefines residential comfort standards. It transforms complex thermodynamic principles into intuitive comfort experiences, enabling technology to truly serve humanity.

When the air conditioner and AC companion work in perfect harmony, they create together not simply a cold or warm environment, but a healthy space with uniform temperature, appropriate humidity, no draft sensation, and low noise levels. Here, you won’t feel the presence of the air conditioner—you will only experience meticulously calibrated comfort—that is the essence of “imperceptible” comfort.

Say goodbye to air conditioner sickness and no longer endure the agony of dry cold and humid heat. Huawa’s AC companion coupling system quietly transforms our relationship with indoor climate, making comfort a daily reality that needs no explanation.
