During scorching summers or freezing winters, air conditioners have become an indispensable “air manager” in modern homes. Yet, while enjoying heating and cooling, many users are plagued by two persistent pain points: soaring electricity bills and uneven, drafty comfort—commonly known as the chronic issues of “high energy consumption” and “low comfort” inherent in traditional air conditioning systems.
To address this industry-wide challenge, huawa has innovatively launched its Coupled Radiant HVAC System, which seamlessly integrates a standard split-type air conditioner with a newly developed smart module called the Air Conditioner Companion. This integration significantly reduces annual operating energy use while delivering the quiet, uniform, draft-free comfort typically associated with “Five-Constant” (Wu-Heng) environments. This is not a simple stacking of two systems—it’s a true system-level re-engineering.
Why Are Traditional Air Conditioners “Energy-Hungry and Uncomfortable”?
Conventional split air conditioners (VRF systems) rely on forced convection via fans for heat exchange. While they offer rapid cooling or heating, they suffer from clear drawbacks:
- High energy consumption: Single evaporator/condenser designs lose efficiency under extreme weather, causing compressors to cycle frequently or run overloaded.
- Poor comfort: Direct cold airflow creates uncomfortable head-cool/feet-warm imbalances and large vertical temperature gradients, often leading to “air conditioner sickness.”
- Weak stability: In low-temperature heating, issues like refrigerant flooding or flash gas can compromise reliability and lifespan.
These limitations have long hindered the evolution of residential air conditioning toward higher quality.
huawa’s Answer: Give Your Air Conditioner a Smart Partner
The core of huawa’s solution lies in introducing an intelligent auxiliary module—the Air Conditioner Companion. It’s not a standalone unit but a deeply integrated “second heat exchange engine” that works in harmony with your existing air conditioner.
In winter heating mode, high-temperature refrigerant first flows through the plate heat exchanger inside the Air Conditioner Companion, transferring part of its heat to a water loop, which then circulates through PE pipes embedded in the floor for gentle radiant heating. The remaining heat is released by the indoor unit, creating a dual-mode output of “radiant + convective” warmth. This two-stage condensation design significantly increases subcooling, enhancing low-temperature heating performance while reducing compressor load.
In summer cooling mode, the process reverses: refrigerant first absorbs the bulk of indoor heat in the indoor unit, then enters the Air Conditioner Companion for secondary evaporation, using the floor to dissipate residual cooling capacity. This ensures stable superheat at compressor return, safer operation, and eliminates direct drafts—creating an ideal microclimate with cooler upper zones and warmer lower zones.
Throughout this process, the air conditioner remains the primary control center, while the Air Conditioner Companion acts like a responsive co-pilot, dynamically adjusting water flow to balance heat distribution and keep the system operating in its optimal efficiency range.
Real User Benefits: Measurable Savings, Tangible Comfort
- 15%–25% higher annual energy efficiency: Thanks to optimized two-stage heat exchange, the system delivers superior COP values in both summer and winter.
- Draft-free, silent radiant cooling/heating: Say goodbye to headaches from direct airflow—ideal for children and the elderly.
- Reliable performance in extreme conditions: Stable heating down to -15°C and cooling up to 45°C without performance drop or shutdown.
- Flexible installation and easy retrofit: No need to replace your existing air conditioner—just add the Air Conditioner Companion and underground piping for an instant upgrade.
Real-world data from a Beijing household shows that with identical usage patterns, families using huawa’s coupled system reduced winter heating electricity costs by nearly 30% compared to standard air-source heat pumps, while maintaining indoor temperature variations within ±0.5°C.
Conclusion: Evolution, Not Revolution
huawa doesn’t discard the mature split air conditioning architecture. Instead, it breathes new life into conventional air conditioners by adding the intelligent “soul” of radiant systems through the Air Conditioner Companion. This is a smart upgrade—“lightweight in modification, heavyweight in experience”—retaining familiar user controls while quietly resolving the fundamental trade-off between energy efficiency and comfort.
The future is here. With huawa’s Coupled Radiant HVAC System, perfect indoor air isn’t a luxury—it’s simply well-engineered.
