H-6730 Environmental Control Trainer for room air conditioning training

The H-6730 is designed to teach the fundamental principles of room air conditioning. It uses a direct expansion coil, a refrigerant-to-air heat exchanger that is located in a lighted duct with a transparent top. This allows students to observe the water vapor condensing on the heat exchanger face. The trainer allows the students to perform the experiments related to Heating air, cooling air, mixing two air streams, conducting heat balance, and determining comfort or discomfort in the controlled space.
