  As technology advances, the cooling systems in shopping malls are constantly being updated. In recent years,   scroll air-cooled chillers   have gained significant attention due to their unique advantages. But is the adoption of scroll air-cooled chillers in shopping malls truly an energy-saving measure, or could it be a waste of resources? Scroll air-cooled chillers offer several benefits in the realm of commercial cooling, particularly for shopping malls. 1. High Efficiency and Energy Saving Scroll air-cooled chillers use scroll compression technology, which is known for its high efficiency and energy-saving characteristics. These chillers are over 20% more efficient than traditional chillers, enabling them to quickly and effectively reduce indoor temperatures and lower energy costs. 2. Easy Maintenance One of the significant advantages of scroll air-cooled chillers is their ease of maintenance. Since they do not require cooling water, there is no need for water replacement and cle

  Ensuring proper water quality and temperature settings is crucial in the operation and maintenance of HVAC chiller systems. This not only guarantees efficient system performance but also extends the equipment's lifespan and reduces operational costs. This article provides an in-depth look into the standards for water quality and temperature settings in chiller system maintenance. 1.Water Quality Standards 1. 1 Total Hardness • Limit: Total hardness should not exceed 300mg/L. • Definition: Total hardness primarily refers to the concentration of calcium ions (Ca²⁺) and magnesium ions (Mg²⁺) in water. • Impacts of Exceeding the Limit: • Pipe Narrowing: High hardness causes mineral deposits on pipe walls, forming scale, which reduces pipe diameter, increases water resistance, decreases chilled water flow, and impairs cooling efficiency. • Increased Energy Consumption: Scale increases water resistance, requiring the chilled water pump to work harder, thus increasing energy consumption

  Industrial chiller units   play a crucial role in various industries, providing chilled water for processes such as plastics manufacturing, electronics production, and pharmaceuticals. However, like any mechanical system, chillers are prone to common problems that can affect their performance. In this blog post, we will discuss these issues and provide practical solutions to keep your industrial chiller running smoothly. Common Problems and Solutions: 1.Insufficient Refrigerant: One common issue with industrial chiller units is insufficient refrigerant. This can lead to decreased cooling capacity and inefficient operation. The solution is simple: supplement the chiller with an adequate amount of refrigerant and maintain the pressure during operation at around 0.5 MPa. 2.High Outdoor Temperatures: During the summer months, excessively high outdoor temperatures can put stress on the chiller's outdoor unit, leading to elevated condensing pressures and temperatures.
