Amid the wave of the global energy revolution, ice thermal storage technology is emerging as a powerful enabler of smarter, more sustainable energy use. As a pioneer with decades of experience in the HVAC industry, H.Stars Group is at the forefront of integrating technological innovation with environmental responsibility—and ice storage is at the heart of this transformation.

At its core, ice thermal storage is a poetic reimagining of time and energy. H.Stars’ self-developed intelligent ice storage system operates by taking advantage of off-peak electricity rates during nighttime hours to produce ice, storing the cold energy in specialized tanks. During the day, when electricity costs spike and cooling demand surges, this "frozen energy" melts, delivering chilled water at 0°C to buildings for efficient air conditioning. This method of “shifting peaks and filling valleys” boosts energy utilization by more than 30% and allows HVAC systems to operate with symphonic balance and precision.

At H.Stars, we've gone beyond the basics—ice storage has evolved into a multi-faceted energy ecosystem that addresses diverse challenges with precision and innovation:

• Industrial Applications:

A glycol ice storage system customized for an automotive manufacturing facility maintains consistent cooling water temperature within ±0.5°C, boosting product yield by 12%.

• Commercial Buildings:

In a major commercial complex in Shanghai, our modular ice storage solution reduced air-conditioning season electricity costs by 40%, cutting carbon emissions by 800 tons annually.

• District Cooling:

In a smart park in Southern China, our distributed ice storage stations, integrated with photovoltaic power systems, optimize clean energy usage and reduce reliance on traditional energy sources.
These real-world cases reflect our transformation from a provider of energy-saving tools to a partner delivering end-to-end energy solutions. By incorporating dynamic load forecasting algorithms and intelligent control systems, H.Stars ensures that every cubic meter of ice releases exactly the cooling energy required—delivering truly on-demand performance.
With China’s dual carbon goals (“peak carbon” and “carbon neutrality”) gaining momentum, H.Stars is scaling up the impact of ice thermal storage across new frontiers:

• Energy Integration:

In a northern data center, our ice storage system works in tandem with waste heat recovery, creating a closed-loop tri-generation system (cooling-heating-power).

• Material Innovation:

Our research into phase-change ice storage materials is increasing cold energy density by 50%, while reducing equipment footprint by one-third.
And the future is even more promising: as ice storage intersects with emerging technologies like hydrogen energy and virtual power plants, it’s no longer just a component of HVAC—it’s becoming a key node in the smart city energy grid.
At H.Stars, we see ice storage not only as an engineering breakthrough, but as a testament to nature’s equilibrium. True innovation, we believe, should shine with technological brilliance while honoring ecological harmony. With ice thermal storage at the core, we continue building a more resilient, intelligent energy ecosystem—where every kilowatt contributes to a sustainable balance between technology and the environment.

Breathability is an important indicator for measuring the comfort of textiles, and is particularly suitable for quality control of products such as sportswear, outdoor equipment, and medical textiles. An air permeability tester can scientifically evaluate the ability of air to pass through fabrics to ensure that the product meets industry standards (such as ISO 9237, ASTM D737, etc.). This article will provide a detailed introduction to the use of an air permeability tester to help you obtain accurate and repeatable test data.

1. Equipment and preparation

(1) Composition of an air permeability tester

Test head: Fixed sample, usually with test holes of different diameters (such as 20cm², 38cm², etc.).

Airflow control system: Adjusts and measures air flow (unit: mm/s or cm³/cm²/s).

Pressure sensor: Detects the pressure difference on both sides of the sample (unit: Pa).

Display/software: Displays test data, and some devices support data export.

(2) Calibration and inspection

Calibration: Calibrate the equipment using a standard calibration plate according to the instructions to ensure accurate data.

Air tightness check: Test whether the airflow is stable when unloaded to avoid air leakage affecting the results.

Environmental conditions: It is recommended to test under standard temperature and humidity (such as 20±2℃, 65±4% RH) to avoid interference from environmental factors.

(3) Sample preparation

Cut at least 5 representative samples (such as 20cm×20cm), avoiding fabric edges or obvious defect areas.

If different parts are tested (such as the front chest and back of the garment), samples must be taken and marked separately.

2. Test steps

(1) Install the sample

1. Loosen the test head clamp and place the sample flat on the test area to avoid wrinkles or stretching.

2. Tighten the clamp evenly to ensure that the sample is fixed and there is no air leakage (you can check by lightly pressing the edge with your fingers).

(2) Set parameters

Test standard: Select the applicable standard (such as ISO 9237, GB/T 5453, etc.).

Test area: Select the test hole size according to the thickness of the sample (small holes for thin fabrics and large holes for thick fabrics).

Pressure difference setting: usually 100Pa or 125Pa, adjusted according to the standard requirements.

(3) Start the test

1. Start the equipment, the system will automatically apply a stable airflow and measure the air permeability.

2. After the value stabilizes (usually 10-30 seconds), record the data (unit: mm/s or L/m²/s).

(4) Repeat the test

Each sample should be tested at least 3 times, and the average value should be taken as the final result.

If the data difference is too large (>10%), it is necessary to check whether the sample is improperly fixed or the equipment is abnormal.

3. Data interpretation and reporting

(1) Common air permeability units

mm/s (millimeter/second): The speed of air flow passing through the fabric vertically.

L/m²/s (liter/square meter/second): The amount of air flow passing through a unit area per unit time.

cfm (cubic feet/minute): Used in some European and American standards.

Summary

Textile air permeability tester is an indispensable tool in research and development, quality inspection and trade. Correct use of equipment and standardized operating procedures can ensure the reliability and comparability of test data. Whether it is product development or acceptance inspection, scientific air permeability evaluation can provide strong support for quality control.

Preparation

1. Check the equipment

① Confirm that all parts of the tensile machine (clamp, handle, dial, etc.) are intact.

② Ensure that the clamp is clean and free of oil or residue to avoid affecting the test results.

2. Calibrate the equipment (first use or regular calibration)

Adjust the pointer to zero according to the manual, or use a standard weight to verify the accuracy of the reading.

3. Prepare the sample

(1) Sew the button to be tested on the standard fabric (or keep the button on the original garment), ensuring that the seam is firm.

(2) Cut the fabric and leave enough area around the button (usually ≥5cm×5cm) for clamping.

Test steps

1. Fix the sample

Upper clamp: clamp the fabric (avoid the seam) and ensure that the fabric is flat and does not slide.

Lower clamp: Clamp the button (if it is a four-hole button, it needs to be fixed with a special clamp or hook).

Note: The direction of the clamp must be consistent with the force direction of the button (such as vertical or horizontal stretching).

2. Start the test

(1) Slowly turn the handle or pull the lever to apply tension at a constant speed (usually the speed recommended is 10-15cm/min).

(2) Observe the connection between the button and the fabric until the button falls off or the stitching breaks.

3. Record data

(1) Read the maximum tension value indicated by the pointer (usually in Newtons N or pounds-force lbf).

(2) Record the damage form when the button falls off (such as stitching breakage, button fragmentation, etc.).

Post-test operation

1. Reset the equipment

(1) Loosen the clamp, remove the sample, and return the handle of the tensile machine to its original position.

(2) Clean the thread or fabric fragments remaining in the clamp.

2. Data analysis

I. Instrument overview

The manual rubbing color fastness tester is used to evaluate the color transfer degree of textiles, leather, coated fabrics and other materials under dry or wet rubbing conditions. The equipment is easy to operate and is suitable for rapid color fastness testing in laboratories or factories. It complies with relevant standards (such as GB/T 3920, ISO 105-X12, AATCC 8, etc.).

II. Test principle

By manually operating the friction device, the standard friction cloth is rubbed back and forth on the surface of the sample with the specified pressure and number of frictions, and the color staining of the friction cloth is observed and compared with the standard grayscale sample card for rating.

III. Operation steps

1. Preparation

Sample preparation:

Cut the sample to be tested with a size of ≥20cm×5cm (adjusted according to the standard), ensuring that the surface is flat, wrinkle-free and stain-free.

Rubbing cloth cutting: Use standard bleached cotton cloth (as specified in GB/T 7568) and cut it into a 5cm×5cm square.

Wet friction test: The friction cloth needs to be soaked with distilled water, and the moisture content is controlled at 100±5% (the moisture can be controlled by wringing).

2. Install the friction cloth

Wrap the friction cloth flatly on the friction head (usually a round friction head with a diameter of 16mm) and fix it with a rubber band or a fixing clip to ensure that there is no looseness or wrinkles.

3. Fix the sample

Spread the sample to be tested flat on the test bench or flat table and fix it with a clamp to prevent movement.

4. Manual friction test

Dry friction test:

1. Press the friction head wrapped with the friction cloth vertically on the surface of the sample.

2. Apply standard pressure (usually 9N or as required by the standard).

3. Rub back and forth 10 times at a uniform speed in the straight direction (one way is about 10cm, speed is about 1 time/second).

Wet friction test:

1. After the friction cloth is soaked, gently squeeze out excess water (avoid dripping).

2. Perform the test according to the dry friction steps. After the friction is completed, remove the friction cloth and dry it immediately.

5. Result evaluation

After the friction cloth is dry (wet friction needs to be dried naturally), compare it with the standard staining gray scale sample card (such as ISO 105-A03) and evaluate the staining level (level 5 is the best and level 1 is the worst).

Record the test results of dry friction and wet friction, and use the lower level as the final evaluation.
