Issues with the air compressor station, thank you for your answer
Thread Content
1. The outlet temperature of the air compressor is around 120 degrees. Why is the inlet temperature only in the 30s degrees when regenerative desiccant drying is initiated for the first time? Our company’s waste heat regeneration system requires an inlet temperature of 85 degrees to operate, and we have to wait for a long time each time. 2. For the circulating cooling water of the air compressor, the manager requires that the inlet be fully open while the outlet should be at half or less capacity – why not have both at full capacity?
I didn’t understand Question 1; I’ll guess at an explanation. After the compressor starts, pressure increases, generating heat; moreover, a certain flow rate is required for the temperature to gradually rise to meet operational requirements. Issue two: Primarily, it is necessary to consider that there is a certain pressure on the water side of the cooler. Return water is used to regulate the cooler’s temperature, thereby preventing the cooling water from taking a shortcut and reducing the heat exchange area... Therefore, during regulation, it is necessary to control the cooling water flow rate at the outlet, adjusting the opening according to temperature changes. For reference.
Thank you for your response. Question 1 is: After the compressor starts, the outlet temperature can reach 115 degrees. However, when the waste heat regeneration system first starts up, the inlet temperature is only in the 30s degrees. The compressed air from the compressor’s outlet goes directly into the waste heat regeneration system—shouldn’t its temperature also be 115 degrees?
Check the location of the measurement points to see if there are any large temperature-control facilities in the middle. It would be best to include a simple diagram for illustration, to facilitate discussion. For reference.
