Introduction

Nestled in the heart of Wenzhou, China, the Zhongjinhui Club stands as a testament to modern engineering and sustainable luxury. This 600 m² high-end venue—featuring executive offices, suites, a grand lobby, and a wine cellar—faces a unique challenge: its floor-to-ceiling glass façade, while stunning, creates significant thermal and humidity control hurdles. Enter Menred’s Five Constants System —a radiant cooling & heating, ERV system, and indoor air quality solutions. In this deep dive, we explore how Menred’s innovation overcame architectural complexities to deliver constant temperature, humidity, oxygen, quietness, and cleanliness —all while slashing energy use by 30%.

1. The Challenge: Glass Walls, Extreme Loads, and Demanding Clients

The Zhongjinhui Club’s all-glass design, spanning four sides of the 11th floor, created a “greenhouse effect,” with solar heat gain and humidity fluctuations threatening comfort. Traditional HVAC systems would have struggled with:

- High Cooling Loads: 160 W/m² due to solar radiation.
- Humidity Control: Wenzhou’s subtropical climate (70–80% RH).
- Aesthetic Constraints: Bulky ducts or visible units clashing with luxury interiors.

Menred’s Five Constants System: A Holistic Solution for Ultimate Indoor Comfort
In today’s pursuit of a healthier and more comfortable living environment, traditional air conditioning and ventilation systems often fall short of addressing all essential indoor climate factors. Menred’s Five Constants System goes beyond conventional solutions by integrating temperature, humidity, CO₂ levels, clean air, and quietness, ensuring a balanced and harmonious indoor atmosphere for modern homes and commercial spaces.

2. System Breakdown: Engineering Excellence Meets Silent Comfort

2.1 Radiant Cooling & Heating: The Silent Powerhouse

Key Components:
- 350 m² Radiant Panels: Embedded in ceilings, these panels circulate chilled water (9°C below room temperature) to absorb heat via thermal radiation, achieving   35 kW cooling capacity   with zero noise.
- 470 m² Floor Conditioning: PEX-A 10mm pipes (5cm spacing) provide supplemental cooling/heating, ensuring even surface temperatures.

Solved Pain Points:
- Noise Elimination: No fans or compressors, keep silent.
- Aesthetic Freedom: Panels blend seamlessly into ceilings, preserving the club’s minimalist design.

2.2 Hybrid Air Source Heat Pumps: Efficiency in Extremes

Innovations:
- Full Inverter Technology: Adjusts output based on real-time demand, reducing energy use by 15% vs. traditional systems.
- Ultra-Low Temperature Operation: -35°C capability ensures reliability in winter.

Performance:
- 160 W/m² Load Mastery: Handled the glass façade’s extreme solar gain.
- Smart Defrosting: AI algorithms prevent ice buildup without interrupting heating.

2.3 AI-Driven Ventilation: Fresh Air, Zero CompromiseBreakthroughs:
- Zoned Pressure Control:
1) Positive Pressure in offices/lobbies: Fresh air inflow.
2) Negative Pressure in kitchens/bathrooms: Odor extraction.
- Intelligent Humidity Control: 70% enthalpy recovery, supporting isothermal/heating/cooling /dehumidification modes.

Outcome: CO₂ levels ≤ 700 ppm,HCHO ≤ 0.07 mg/m³—exceeding WHO standards.

3.Five Constants Achieved: A New Benchmark in Indoor Excellence

Menred’s Five Constants System indoor comfort indicators:

- Temperature:22-26℃

- Humidity:35%-65%

- Oxygen: CO2≤700ppm,HCHO≤0.07mg/m³

- Clean: PM2.5≤25ug/m³,energy recovery ventilator

- Quiet: 35dB(A), Silent and windless air-conditioning panels

The Five Constants are not just abstract notions, they are grounded in national standards and international benchmarks like ISO7730.Using standards as the design foundation, quantifiable standards, and verifiable results.

Metric	Performance	Industry Standard
Temperature	±0.5°C fluctuation (A+ level)	±2.0°C (Typical HVAC)
Humidity	35–65% RH, Automatic Isothermal Dehumidification	30–70% RH (Conventional)
Air Quality	PM2.5 ≤25 μg/m³, CO₂ ≤700 ppm	PM2.5 ≤75 μg/m³ (EPA)
Noise	35 dB(A) (Fanless Silent air conditioning Panels)	50–60 dB(A) (Traditional AC)
Energy Use	≤900 kWh/month (100 m² Benchmark)	1,200–1,500 kWh/month

4. Smart Controls: One Pad to Rule Them AllFeatures:

- Adaptive Algorithms:Adjusts water temperatures based on dew points, preventing condensation.
- Remote Management: GPRS/ModBus integration allows real-time monitoring via mobile apps.
- Peak Shaving: Stores “coolth” overnight in thermal mass, cutting daytime energy costs by 25%.

5. Why This Project Matters: A Blueprint for Sustainable Luxury

- Architectural Integration: Curved panels in the lobby showcase how HVAC can enhance aesthetics.
- Energy Efficiency Leadership: Achieved 30% energy savings through advanced heat pumps and AI optimization.
- Scalability: Solutions adaptable to smart homes, offices, and hotels.
