AC Companion Coupled Radiant System: The Ultimate Solution for Future Home Climate Control
In today’s rapidly evolving HVAC technology landscape, we face a core challenge: how to pursue energy efficiency while providing more comfortable and flexible temperature management solutions? Traditional centralized heating and cooling systems are increasingly proving inadequate when addressing diverse and personalized needs. This article delves into an innovative solution—the AC Companion-based coupled radiant air conditioning system—and analyzes why it represents the optimal solution for various scenarios.
Limitations and Challenges of Traditional Climate Control Systems
Traditional temperature regulation systems are mainly divided into two categories: centralized and decentralized. Centralized systems such as central air conditioning and regional boiler heating are suitable for high-density population scenarios but suffer from low efficiency and high costs in situations like rural left-behind households, communities with low occupancy rates, and partial room usage in villas.
Decentralized systems like ordinary split air conditioners address flexibility issues but still suffer from low energy efficiency ratios, poor comfort (strong drafts, uneven temperatures), and weak adaptability to extreme climates. Particularly in high humidity environments in southern China during summer, traditional AC units have poor dehumidification效果, easily causing condensation issues that affect indoor air quality and human comfort.
AC Companion Coupled Radiant System: Working Principles and Innovative Breakthroughs
System Composition and Core Innovation
This system consists of three main modules: traditional split AC system, AC Companion, and radiant terminal system. Its core innovation lies in:
- The AC Companion serves as an incremental device, containing plate heat exchangers, circulating water pumps, and intelligent control units, enabling efficient heat transfer between refrigerant circuits and water circuits.
- The underground PE pipe radiant terminals act as the system’s “energy storage body” and “radiant heat exchange surface,” working in coordination with traditional air conditioning.
Revolutionary Operating Modes
The system implements two efficient operating modes through unique flow design:
Winter Heating Mode: Uses an “A-B-C cycle” path where refrigerant sequentially passes through outdoor unit, AC Companion, and indoor unit. This two-stage condensation design significantly increases effective condensation area, enhancing system subcooling, enabling stable operation even in low-temperature environments.
Summer Cooling Mode: Uses an “A-C-B cycle” path where refrigerant flows through outdoor unit, indoor unit, and AC Companion in sequence. This two-stage evaporation process not only improves system superheat but also combines overhead convective cooling with underfloor radiant cooling, effectively reducing vertical temperature differences and mean radiant temperature indoors.
Comprehensive Comparative Analysis with Traditional Solutions
1. Energy Efficiency Performance
Compared with traditional systems, the AC Companion coupled system significantly improves annual energy efficiency ratio by increasing subcooling and superheat.
- Compared to central AC systems: In partial load situations (using only 1-2 rooms), energy consumption can be reduced by over 40%, solving the energy waste problem of “using a sledgehammer to crack a nut.”
- Compared to ordinary split ACs: Cooling coefficient of performance (COP) increases by approximately 25%, while heating coefficient of performance (COPh) increases by about 30%, with advantages being particularly evident at very low external temperatures.
2. Comfort Experience
The system integrates both convective and radiant heat transfer methods, creating a draft-free comfortable environment:
- Vertical temperature difference control: Compared with traditional AC, indoor vertical temperature differences can be controlled within 2°C, far below the 4-5°C differences of traditional systems.
- Humidity regulation: By precisely controlling radiant panel surface temperature, it effectively prevents condensation, maintains suitable humidity, solving the floor condensation problem during rainy seasons in southern regions.
- Uniform temperature field: Radiant cooling and heating create more uniform temperature distribution, avoiding “hot and cold spots” common with traditional AC systems.
3. Adaptability and Flexibility
The AC Companion coupled system perfectly addresses flexibility needs across different usage scenarios:
- Partial space usage: For rural left-behind households or partial room usage in villas, the system provides climate control only for occupied rooms, avoiding energy waste from running entire central systems.
- Retrofit adaptability: In existing building renovations, no large-scale piping work is required—only installation of AC Companion and radiant terminals, significantly reducing renovation difficulty and cost.
- Expandability: The system supports modular expansion, allowing gradual increase of radiant terminal coverage according to needs.
4. Economic Analysis
From a full lifecycle cost perspective, the AC Companion coupled system demonstrates significant advantages:
- Initial investment: Lower than traditional central AC + radiant floor heating systems, comparable to high-end multi-split systems.
- Operating costs: 30-40% lower than traditional split AC systems, over 50% lower than central AC systems under partial load conditions.
- Maintenance costs: Modular design simplifies system maintenance, with local failures not affecting overall operation.
Optimal Solution Analysis for Different Scenarios
Urban Residential Scenarios
For urban apartments and ordinary residences, the AC Companion coupled system provides solutions with high space utilization and convenient installation. Particularly for finished luxury apartments, the system can be installed simultaneously with decoration, achieving the comfortable experience of “Five Constant Systems” (constant temperature, humidity, oxygen, cleanliness, and quietness).
Rural and Low-Density Residential Scenarios
For rural left-behind households and communities with low occupancy rates, the system perfectly addresses the economic inefficiency of traditional centralized heating. Residents only pay for the spaces they actually use, avoiding energy waste while enjoying high-quality climate control experience.
Special Climate Regions
In high humidity areas, the system precisely controls radiant surface temperature while incorporating independent dehumidification systems, effectively preventing condensation and solving the technical bottleneck of traditional radiant cooling systems in hot and humid regions.
Future Trends and Sustainable Development
Integration with New Energy Power Generation
As nuclear power generation and new energy power generation costs continue to decline, future electricity supply will become cheaper and more abundant. The AC Companion coupled system, as a fully electric-driven solution, will directly benefit from this trend. The system can also integrate phase change materials (PCM) as energy storage media to further improve system efficiency.

Refrigerant Transition Opportunity
Facing the global transition trend toward A2L refrigerants, the AC Companion coupled system design can adapt to new environmentally friendly refrigerants, making future upgrades more convenient and avoiding technical obsolescence risks of traditional systems.
Conclusion: Optimal Choice in Gradual Transition
In the long river of climate control technology development, various solutions will inevitably coexist for a long time, just as smartphone photography has become ubiquitous while traditional cameras remain in professional use. However, for most application scenarios, the AC Companion coupled radiant system truly represents the optimal solution under current technological conditions.
It has not only achieved breakthrough progress in energy efficiency, comfort and flexibility, but also demonstrates significant advantages in economy and adaptability. Particularly with the declining costs of new energy power generation and maturation of artificial intelligence technology, the system’s development prospects are even broader.
The AC Companion coupled system successfully solves the industry challenge of “partial space usage,” providing perfect solutions for scenarios like rural left-behind households, communities with low occupancy rates, and partial room usage in villas, achieving the ideal goal of “energy supply on demand,” representing an important milestone toward sustainable development and personalized comfort.
