Direct-expansion VAV air conditioner experiment rig and its performance experiment

Builds an adjustable air volume direct-expansion refrigeration system experiment rig, solves some problems in the design and constructing process of the experiment rig, determines more stable and perfect control and data acquisition system, and provides an interactive simulation interface. Designs a kind of experimental scheme that can partly validate system performance, tests the ability of frequency conversion compressor dealing with latent heat and sensible heat loads under different conditions, and verifies the various models by experiment. Based on the test results, modifies some models and verifies the accuracy and stability of the system.
