The test equipment is suitable for the performance test of household indoor unit within 3HP (including 3HP). The detection system is equipped with a computer host (main control computer system), which manages n (n ≤ 60) data acquisition systems (detection station system). The main control computer system sets and manages the whole test process and test steps, and sends the test process and test steps to the detection station system through the network. The test station system responds to the host command through network communication and feeds back the test process data. The main control computer system manages and monitors the test process of each test station, collects and saves the test data of each air conditioner; reads the test data of each test station and saves the data, reads the product barcode of the electrical safety performance test station, and communicates with the safety performance tester to read and save the data.
