The 30HP Ice Storage Chiller system (with a cooling capacity of approximately 88kW) has become a popular solution for energy-efficient cooling, particularly in regions with significant price differences between peak and off-peak electricity rates. However, the cooling coverage area is not fixed and varies depending on multiple factors. In this blog, we will discuss the system's estimated cooling capacity, ideal use cases, and strategies to enhance its cost-efficiency.

1. Estimating the Cooling Capacity of a 30HP Ice Storage Chiller System (Approx. 88kW)

The cooling capacity supported by a 30HP ice storage chiller depends on various factors, including building type, insulation, equipment efficiency, and load matching. Here's an estimation based on different applications:
• Office Buildings: For typical office buildings with cooling loads around 100-120W/㎡, the system can cover approximately 730-880㎡.
• Commercial Buildings: In commercial spaces with a cooling load of 150-200W/㎡, the coverage is around 440-580㎡.
• High-Density Spaces (e.g., Data Centers): In environments with higher loads of >500W/㎡, the system can only cover about 175㎡.
The cooling coverage will also be affected by:
• Building Insulation: Better insulation leads to more efficient cooling.
• Equipment Age & Efficiency: Newer, more efficient systems deliver better performance.
• Ice Storage Strategy & Melting Speed: The amount of ice stored and the speed of melting must match peak daytime load demands.
Thus, the 30HP chiller is ideal for cooling spaces ranging from 500 to 800㎡ for regular commercial or office spaces, but precise calculations should be made based on the specific project's cooling load.

2. Ideal Applications for Ice Storage Chiller Systems

While ice storage chillers offer great energy-saving potential, their economic benefits are most pronounced in certain scenarios:
• Regions with Significant Off-Peak Pricing: The presence of a large price differential between peak and off-peak electricity is essential for optimizing savings.
• Short-Duration, High-Cooling Load Scenarios:
o Shopping Malls, Theaters, and Stadiums: These venues often experience high peak cooling loads during business or event hours, coinciding with high electricity prices.
o Office Buildings: Concentrated cooling needs during working hours, especially in the afternoon, can be met by the chiller's ability to supply cooling steadily through ice storage.
o Data Centers: These require continuous cooling year-round, and ice storage can help balance peak daytime loads.
o Hospitals and Laboratories: Certain areas need 24-hour cooling, which the system can provide using ice storage for stable daytime supply.
o Power Capacity Limited Projects: Ice storage can significantly reduce daytime peak power demand, alleviating strain on transformers and saving on capacity expansion costs.
o Critical Facilities with High Cooling Stability Needs: Ice storage can serve as an emergency cooling source, improving the reliability of the system.

Looking ahead, 120°C hot water units have a clear evolution path. They’ll grow more energy-efficient and eco-friendly, integrating better with clean energy sources like solar and geothermal as renewables mature—cutting carbon emissions for sustainability. Smart capabilities will deepen too: via the internet and big data, units will enable remote monitoring, fault (early fault warnings), and automatic operation optimization, delivering more convenient, efficient user experiences. Additionally, miniaturization and modular design will let units adapt flexibly to diverse scales and site conditions.

With current technological breakthroughs, 120°C hot water units already excel in various fields. Following their future evolution path, they’ll play an even more critical role in driving efficient energy use and industrial upgrading—bringing positive impacts to societal development.

In today’s era of pursuing efficient and eco-friendly energy use, the choice of water source is crucial for scroll heat pump units, a key heating and cooling equipment. After comprehensive consideration and practical verification, groundwater is undoubtedly the most ideal water source for these units.

Groundwater boasts stable temperature characteristics. Unlike surface water, which is greatly affected by seasons and climate, groundwater maintains a relatively constant temperature year-round. This is vital for the stable operation of scroll heat pumps. In winter, when surface water temperatures drop sharply, groundwater remains at a suitable level, providing a sufficient and steady heat source for the pump to ensure heating efficiency. In summer, when surface water becomes too warm for cooling, the lower temperature of groundwater helps the unit cool efficiently, reducing energy consumption and boosting overall operational performance.

If you've ever wondered why 18 inch 5 holes forged wheels are so popular, the answer lies in their careful manufacturing process. 

 

These wheels— a common size for many passenger cars and SUV cars— go through a series of precise steps that guarantee quality, strength, and consistency, traits that make them stand out from mass-produced alternatives.

 

The process starts with picking the right materials. Most 18 inch 5 holes forged wheels use high-grade aluminum alloys like 6061, chosen for their great strength-to-weight ratio. First, the aluminum block is heated to a specific temperature to make it malleable, then placed in a forging press that uses thousands of tons of pressure to shape it into a rough wheel blank. This step is critical: it gets rid of air bubbles and lines up the metal’s grain, creating a structure far stronger than cast metal.

 

Next comes heat treatment. The wheel blank goes through solution heat treatment and aging, which strengthens the aluminum by forming tiny precipitates in its microstructure. This ensures the wheel can handle daily driving stresses— from hitting potholes to cornering at high speeds. After heat treatment, the blank moves to machining, where precise tools refine its size, carve out spokes, and drill the 5 bolt holes. Each hole is measured exactly to fit the vehicle's hub perfectly.

 

The wheel is polished, painted, or powder-coated to boost its appearance and protect it from corrosion. This not only makes 18 inch 5 holes forged wheels look great but also extends their lifespan, keeping them in top condition for years. Quality control checks happen at every stage, from material inspection to final assembly, to catch any defects and maintain high standards.

 

The result? A wheel that's not just good-looking but also incredibly durable and reliable. 18 inch 5 holes forged wheels earn their reputation from this strict manufacturing process, which combines advanced technology with skilled craftsmanship. For drivers who want both style and performance, these wheels are proof of how much quality manufacturing makes a difference.

In the production process of corrugated cardboard, sometimes there will be some production problems, if it can not be solved in time, the whole production will be forced to stop.

Belows are some common problems occurs and solutions as your reference:

1. The corrugated is not high enough.

The reason may be the pressure or temperature is too low, or moisture content is too high. And the solution is to adjust the pressure or roll temperature, or reduce the speed to dry.

2. Corrugated height is not uniform, the length of the sheet on both sides that pressed out are different which likes circular sector.

This is due to the corrugated roller parallelism is not good or uneven pressure at both ends. If the left corrugated sheet is shorter than the right, it’s better to raise up the left side of the top corrugated roller,  otherwise to do the reverse adjustment.

3. Corrugated sheet curl like tube shape, the main reason is that the temperature difference between the upper and lower roller is too obvious.

You should check the heating source in the upper and lower rollers. It may be repaired or replaced if one of the heating sources break down.

4. The corrugated sheet is stuck to the surface of the corrugated roller.

The roll surface temperature is too high or the moisture content of raw sheet is too large will occur this situation. At this time, you should adjust the temperature of the roll surface to let the sheet be dry and then crease, if the doctor blade and roll groove is not fit, you should adjust or replace it.
