High-Pressure Atomization Cooling System: Evaporative Cooling Outdoor Environment Regulation Technical Guide

I. System Overview The High-Pressure Micro-Mist Evaporative Cooling System is an evaporative cooling technology specifically designed for outdoor open spaces. It uses a high-pressure pump to atomize water into ultra-fine mist droplets (Dv50 ≤ 4μm), absorbing heat through the latent heat of water evaporation to achieve local temperature reduction of 3–8°C while creating attractive landscape effects. It is suitable for semi-open spaces such as commercial plazas, stadiums, and theme parks. It serves as an ideal alternative to traditional air conditioning, which suffers from high energy consumption and limited coverage. The system integrates multi-parameter sensors and can dynamically adjust misting strategies based on dry-bulb/wet-bulb temperature, wind speed, and solar intensity, achieving sensible heat reduction of 3–8°C. The complete technical solution is provided by Taining Kechuang. It has been successfully applied in multiple domestic stadiums, commercial plazas, and parks, and has served the thermal comfort needs of the Chinese Super League and international events. Typical Application Scenarios: Commercial plazas and pedestrian streets Urban parks and green spaces Stadiums and spectator stands Tourist attractions and theme parks High-end hotels and resorts High-temperature, dry, or tropical regions II. Evaporative Cooling Principle Ultra-fine mist droplets are sprayed into the air, absorbing latent heat of vaporization (≈2260 kJ/kg) through evaporation and lowering the dry-bulb air temperature. The theoretical cooling limit is the wet-bulb temperature of the air. Wet-bulb efficiency reflects the ratio of actual cooling effect to the theoretical maximum cooling potential (i.e., the dry-bulb/wet-bulb temperature difference). Higher efficiency means the misting system is closer to the ideal evaporative cooling state. Key factors affecting evaporative cooling performance include: ambient dry-bulb temperature, relative humidity, droplet size, spray velocity, and air velocity. Parameter Influence Relationship Typical Range Dry-bulb Temperature (°C) Higher = greater cooling potential 30–45 Relative Humidity (%) Lower = more significant cooling effect 20–80 Droplet Size (μm) Smaller = faster evaporation rate ≤4 Spray Velocity (m/s) Affects air mixing 15–25 Air Velocity (m/s) Affects residence time 0.5–3 Typical Conditions: Dry-bulb 35°C, 45% RH, ≤4μm droplets → local cooling of 5–8°C within 3 minutes. 2.1 Comparison of Outdoor Cooling Methods Comparison Dimension High-Pressure Misting System Compressor Air Conditioning Evaporative Air Cooler Energy Efficiency Ratio (EER) ≥20 2.5–3.5 8–12 Cooling Capacity per Unit Area (W/m²) 150–250 200–300 80–120 Application Range Open spaces Enclosed spaces Local Initial Investment (USD/m²) 10–15 35–60 4–6 III.

High-Load Ceramic Silica Sand Permeable Pavers: -40°C Freeze-Resistant, No Waterlogging in Heavy Rain, 50-Year Lifespan Sponge City Pavement

I. Overview Ceramic silica sand permeable pavers are high-load permeable paving materials specifically designed for sponge cities and extreme climate conditions. Imagine this: after a heavy rainstorm, there is no standing water on the pavement — rainwater quickly infiltrates into the ground. At noon in summer, the ground temperature is more than 20°C lower than adjacent asphalt roads, and you can walk barefoot without burning your feet. This is not science fiction — it is the “breathing pavement” being implemented in more and more cities worldwide. The core material is ceramic silica sand permeable pavers. Core Performance: Compressive strength ≥ 45 MPa Permeability rate: 20 mm/s No damage after 25 freeze-thaw cycles at -40°C Surface temperature 20–25°C lower than asphalt Runoff control rate ≥ 85% under 50-year storm events Service life exceeding 50 years As one of the earliest companies in China engaged in permeable paving R&D, we have discovered through 20 years of practice that good permeable pavers must not only “permeate water” but also “withstand” extreme weather. From severe cold and freeze-thaw in the north, to heavy rain and waterlogging in the south, and arid heat in the Middle East — we have seen too many cement-based permeable pavers fail after just a few years. These hard lessons led us to turn to high-temperature sintered ceramic materials. The Permeable Ecological Ground System, with high-load ceramic silica sand permeable pavers as its core product, follows the principles of “infiltrate, retain, store, and purify.” It restores the soil-atmosphere-vegetation water cycle while meeting load-bearing requirements. This system is suitable for sidewalks, plazas, parking lots, and residential communities, and can operate stably under extreme climatic conditions — this is what sets it apart from ordinary permeable paving. II. Core Technical Principles 2.1 Why Choose Sintered Ceramics? A Lesson from the North Ten years ago, we used cement permeable pavers for the first time on a northern project. That winter was exceptionally cold. When we returned the following spring, we found large areas of the pavement had freeze-cracked — some bricks had even shattered into pieces. The owner asked us: “You said it was permeable, but you didn’t say it would freeze and break.” That lesson taught us that permeability and durability must be solved simultaneously. Back in the laboratory, we began studying the closed-pore structure of sintered ceramics. The secret of this structure is that after sintering at 1200–1300°C, the material forms a large number of closed pores inside. Water molecules cannot enter, so there is no place for freeze-expansion stress to act, and thus no damage occurs. Based on this discovery, we spent five years optimizing raw material ratios and sintering processes to create today’s ceramic silica sand permeable pavers. Materials and Process Selected ceramic raw materials and silica sand are used. After particle screening, grading, 1600-ton high-pressure molding, and high-temperature sintering (1200–1300°C for 8–12 hours). The sintering process adopts a stepped heating curve, with a 1–2 hour hold at 800–900°C to fully burn out the pore-forming agents, ultimately forming a mullite phase crystal bridge connection structure. Permeation Mechanism: How to Achieve “Permeable Yet Non-Absorbent”? This may sound contradictory, but the principle is simple. Permeability relies on open pores (commonly known as “water channels”). With an open porosity of 20%–25% and pore diameters of 50–200 μm, rainwater quickly infiltrates through these channels. Durability relies on closed pores (the “waterproof barrier”). Water absorption rate ≤ 0.5%. Since water molecules cannot enter, the material naturally resists freezing damage. One brick with two functions — the key lies in precise control of the sintering temperature. Measured permeability coefficient ≥ 2.0 × 10⁻² cm/s — which translates to 20 mm/s. This means 1 square meter of paver surface can permeate 20 liters of water per second — equivalent to a bucket of water disappearing into the ground in the blink of an eye. Anti-Slip Performance: The Secret to Staying Steady in the Rain We conducted a test: half of the same batch of pavers were polished, the other half left in their original state. After pouring water on them, people walked across. The polished bricks were noticeably slippery, while the original bricks remained stable. The reason is that ceramic silica sand permeable pavers form a micro-rough surface structure through particle grading, and we deliberately avoid glazing. Dry BPN ≥ 70, wet BPN ≥ 60 — these figures mean you can walk as steadily on them in heavy rain as on a sunny day. Freeze-Thaw Resistance: Surviving -40°C Tested according to ASTM C67 standard for 25 freeze-thaw cycles: mass loss ≤ 0.5%, compressive strength retention ≥ 95%. More convincing are the field results. Ten-year tracking observations in Calgary, Canada (-35°C winters) and Harbin, China (-32°C winters) show: no surface cracking or spalling, with permeability retention ≥ 85%. In contrast, cement permeable paver areas on the same streets saw permeability drop by 40%–60% after 10 years. Extreme High Temperatures: Our Comparison with Asphalt Pavement During Beijing’s 40°C+ heatwave in summer 2022, we measured at the Olympic Center area: Asphalt pavement: 65°C Ordinary concrete pavement: 55°C Ceramic silica sand permeable pavers: 35°C Why such a big difference? Three reasons: Continuous evaporative cooling from moisture in the pavers Higher solar reflectance of light-colored surfaces The breathable structure allows cooler air from below to convect upward — like a built-in “air conditioner” for the ground. Extreme Heavy Rain: Standing in the Typhoon at Hongqiao On the day Typhoon Bebinca made landfall in Shanghai in 2024, our engineers stood in the permeable paving area at Hongqiao Business District wearing rain boots. The rain was so heavy the umbrella could barely hold, yet there was never any standing water underfoot. A colleague standing on asphalt nearby reported: water was already above the ankle. When combined with a permeable base (permeable concrete + graded gravel), ceramic silica sand permeable pavers achieve a runoff control rate of 85%–90% under a 50-year storm (90 mm/h), with peak delay of 15–30 minutes. This not only prevents waterlogging on the surface but also gives the municipal drainage system a breather. Arid Conditions: What Happens After 90 Days Without Watering? We conducted an extreme drying test: pavers were placed in a 70°C oven for 90 consecutive days. Upon removal, there was no cracking or deformation. The structural stability of sintered ceramics makes them resistant to drying shrinkage — especially important in arid and semi-arid regions where cement-based materials easily crack after long-term drying. Tropical High-Humidity: A “Forbidden Zone” for Mold and Algae In 2023, we received feedback from a project in Singapore: after three years, the permeable paver surface showed no algae or mold growth. In contrast, the adjacent cement permeable paver area had already turned green. The reason is simple: ceramic surfaces fired at 1200°C contain no nutrients. Mold and algae have nowhere to take hold. Comparative tests show cement permeable pavers develop noticeable algae in 3–6 months, while ceramic permeable pavers remain clean even after 12 months. Moss Maintenance: Just Sweep Regularly Ceramic silica sand permeable pavers themselves do not grow moss — this is determined by high-temperature sintering. However, accumulated leaves and dust can foster moss in humid conditions if not cleaned. The solution is simple: quarterly sweeping and annual high-pressure washing. Permeability can still remain above 70% after ten years. Source: Leader in Permeable Ecological Ground Systems — Taining Kechuang III. Where Do the Raw Materials Come From? — A Story of “Waste Utilization” Many people ask: Is it true that 75%–85% of your bricks are made from industrial waste? This story begins in 2010. While visiting several ceramic factories in Hebei, we saw mountains of waste blanks, broken bricks, and cutting scraps — “waste” in the ceramic industry, but “treasure” in our eyes. We began researching how to crush, screen, and reuse these materials. After years of effort, the formulation stabilized. Each square meter of paver can consume 120–150 kg of solid waste. For a 100,000 m² project, that means recycling 1.2–1.5 million tons of industrial waste. This is not just business — it is responsibility. Raw Material Composition of Ceramic Silica Sand Permeable Pavers Raw Material Category Main Components Mass Percentage Function Circular Economy Attribute Aggregate Silica sand, ceramic waste, coal gangue 75%–85% Framework & permeable channels Industrial solid waste utilization Binder Kaolin, bentonite 10%–15% Melt sintering & forming Natural minerals Flux Feldspar, talc 3%–5% Lower sintering temperature Energy saving Pore-forming Agent Carbon powder, wood chips 1%–2% Adjust porosity Biomass waste Colorant Inorganic pigments 0.5%–2% Stable color Non-toxic & eco-friendly Note: Ceramic waste refers to green body scraps, fired rejects, and cutting scraps from architectural ceramics, crushed and screened to 0.5–3 mm particle size for continuous grading with silica sand. Process Flow: Raw material screening → Batching & mixing → High-pressure forming → Drying → High-temperature sintering (1200–1300°C) → Final inspection Lifecycle Carbon Footprint: With a 50-year service life, annual carbon emissions ≤ 4.0 kg CO₂e / m² / year — lower than cement permeable pavers and permeable asphalt. Source: Leader in Permeable Ecological Ground Systems — Taining Kechuang IV. System Structure and Construction Key Points 4.1 Structure (Top to Bottom) Surface layer: Ceramic silica sand permeable pavers (50–60 mm) Leveling layer: Coarse sand / stone chips (30–50 mm) Base layer: Permeable concrete or graded gravel (150–300 mm) Sub-base: Permeable crushed stone (100–200 mm) Geotextile protection + compacted subgrade ≥ 93% 4.2 Construction and Maintenance Key Points A well-leveled and compacted base is critical — we have seen too many projects fail due to poor base preparation, leading to settlement after just a few years. It is better to spend two extra days ensuring a solid base than to cut corners. After laying, use fine sand for joint filling and adopt interlocking patterns. Maintenance is straightforward: regularly sweep leaves and dust, clean oil stains with detergent, treat rust with oxalic acid, then rinse with high-pressure water. V. Typical Application Cases Case Area Key Indicators Site Story Beijing Olympic Center Plaza 50,000 m² Stormwater ponding ≤ 5 mm, fully infiltrates in 30 min Built in 2008, withstood countless heavy rains with zero ponding Shanghai Hongqiao Business District 80,000 m² Annual rainwater infiltration 60,000 m³ During 2024 Typhoon Bebinca (112 mm/h), no ponding while adjacent asphalt had ankle-deep water Xiong’an New Area Civic Service Center Parking area Runoff control rate 91.5%, summer surface temp 6.2°C lower In Xiong’an’s scorching summers, asphalt can fry eggs while permeable pavers stay cool VI. Global Quick Selection Guide Environment / Requirement Recommended Solution Why Choose It Severe cold regions Ceramic silica sand permeable pavers Closed-pore structure, -40°C freeze-proof, 85% permeability retention after 10 years Extreme high-temperature regions Ceramic silica sand permeable pavers Surface 20–25°C cooler than asphalt, built-in cooling effect Heavy rain-prone regions Ceramic silica sand + permeable base ≥85% runoff control under 50-year storms Arid/semi-arid regions Ceramic silica sand permeable pavers No cracking after 90 days drying (unlike cement) Tropical high-humidity regions Ceramic silica sand permeable pavers No algae/mold after 12 months (cement shows growth in 3–6 months) High-density commercial areas Interlocking ceramic silica sand pavers ≥50 MPa strength, pedestrian + light vehicle suitable Light vehicle lanes Interlocking ceramic silica sand pavers Structural joints allow permeability while maintaining integrity VII. FAQ Q1: Can ceramic silica sand permeable pavers handle vehicles? A: Standard type is suitable for pedestrians. Interlocking type (structural joint permeable pavers) can handle light vehicles and private car parking. For heavy traffic, use permeable concrete or asphalt. We tested with a 3-ton SUV repeatedly driving over interlocking pavers — the bricks remained intact. Q2: What if it gets clogged? A: Quarterly leaf/dust sweeping and annual high-pressure washing. Oil stains can be cleaned with detergent; rust with oxalic acid. Permeability can still exceed 70% after 10 years. One Shanghai project maintained 80% permeability after 8 years. Q3: Can it be used in northern regions? Will it freeze and break? A: We have installations in Calgary (-35°C) and Harbin (-32°C) that have endured 10 winters with no cracking, no spalling, and ≥85% permeability retention. Cement pavers in the same areas lost 40–60% permeability. Q4: Does it get hot underfoot in summer? A: Under direct midday sun, asphalt reaches 65°C, ordinary concrete 55°C, and our pavers only 35°C. We have real measurements from Beijing Olympic Center. Q5: Will it pond during heavy rain? A: With a proper permeable base, it handles 50-year storms (90 mm/h). During Typhoon Bebinca (112 mm/h) in Shanghai Hongqiao, the permeable area had no ponding while adjacent asphalt had 8–12 cm deep water. Q6: Will it crack in arid regions? A: No. Bricks showed no damage after 90 days in a 70°C oven. Sintered ceramics resist drying shrinkage, unlike cement-based materials. Q7: Will it grow algae or mold in tropical regions? A: In Singapore projects after 3 years, surfaces remained clean. Adjacent cement pavers turned green within 3–6 months. Ceramics fired at 1200°C provide no nutrients for mold or algae. Q8: Will moss grow? A: The pavers themselves do not grow moss, but accumulated leaves and dust can in humid conditions. Regular sweeping and high-pressure washing solve this. Q9: How much does it improve thermal comfort? A: Evaporative cooling of 3–8°C, plus surrounding vegetation, improves perceived temperature by 5–10°C. Measurements in Xiong’an confirmed it feels much cooler than asphalt. VIII. Conclusion: One Brick, Twenty Years Core Performance Recap: Compressive strength ≥ 45 MPa, permeability 20 mm/s, no damage after 25 freeze-thaw cycles at -40°C, surface temperature 20–25°C lower than asphalt, ≥85% runoff control under 50-year storms, and a service life exceeding 50 years. From the 50,000 m² installation at Beijing Olympic Center in 2008 to standing up to Typhoon Bebinca in Shanghai Hongqiao in 2024, ceramic silica sand permeable pavers have proven themselves over nearly 20 years across extreme climates. If you are selecting materials for a project, remember these numbers: ≥45 MPa compressive strength — safe for pedestrians and light vehicles 20 mm/s permeability — no waterlogging in storms -40°C freeze resistance — safe for northern regions 20°C cooler than asphalt — comfortable in summer ≥85% permeability retention after 10 years — low maintenance This is not just data — it is the confidence we have gained from laying brick after brick on real project sites.
