  Maintaining optimal temperatures in   HVAC chiller system   components is essential for their efficient operation. Abnormal temperature ranges can signal potential issues that need timely analysis and intervention. While precise temperature measurements might be challenging, manual estimation by touch often helps in detecting these anomalies. Here’s an in-depth look at ten critical temperature points for effective chiller maintenance. 1. Discharge Temperature Normal and Abnormal Conditions: • High Discharge Temperature: During summer, the compressor’s discharge temperature is high and untouchable. This may indicate high suction temperatures or excessive condensing temperatures. • Low Discharge Temperature: If the discharge pipe is not hot, it suggests very low suction temperatures or low refrigerant levels, potentially causing valve structure damage or insufficient motor winding cooling. 2. Compressor Shell Temperature Impacts and Causes: • Normal Temperature: The shell...

  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...

  In the process of producing stretch film, the cooling system is very important, which directly affects the quality and output of stretch film. In general, we recommend choosing a chiller model with a cooling capacity slightly larger than the flow rate required for cooling, so as to ensure that the temperature and water flow rate can be kept within the required range under long-term stable operation. When choosing a water chiller system for your stretch film machine and film blowing machine, there are several factors to consider: Cooling Capacity: Determine the cooling capacity required for your machines based on their heat load. Consider factors such as the machine size, material type, production rate, and ambient temperature. Temperature Control: Assess the temperature control requirements of your machines. Depending on the application, you may need precise temperature control to achieve optimal production conditions. Chiller Type: Select a chiller type that suits your specific ...

  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.
