AIR CONDITIONING AGING TEST SYSTEM
System Features:
Self-developed multifunctional network data acquisition and control module, combined with virtual instrument LABVIEW software technology. Monitors the working voltage, current, and power of each product, communicating with the products via RS485. Instantly reads the status of air conditioning compressors and fan speeds; these parameters can be set by the upper computer to determine upper and lower limits. Maximum power for refrigeration air conditioning: 220VAC, maximum current 20A, 2500W; DC voltage 48V, maximum DC current 33A. Product aging quantity: 32 products, moved by cart, with a total of 8 mobile carts, each holding 4 products. Each oven has an independent circulation fan, ventilation heating function, one cart corresponds to one oven, and the cart's power supply and communication automatically dock. Test data can be saved on a computer and uploaded to SHOPFLOOR. Displays curves for qualified and unqualified products.
An Air Conditioning Aging Test System is a specialized platform designed to evaluate the long-term performance, reliability, and durability of air conditioning systems under various simulated environmental conditions. This system helps manufacturers ensure that their units can withstand prolonged use and harsh operating environments. Here are the key components and tests typically involved in such a system:
