DLZL-AC05 Advanced Computerized Air Conditioning Cycle Test Bench

1. Overview

At present, the training device can carry out the actual hands-on operation of the electrical control circuits listed in the textbooks of “Elementary Maintenance Electric Refrigeration Technology” and “Intermediate Maintenance Electrician Technology”, so that after the operation training, the students have been improved in the following skills:

(1) Familiar with the structure, principle, installation, and use of common low-voltage electrical appliances;

(2) Understand how to use graphic symbols and text symbols in circuit diagrams, and be able to follow the physical layout,

(3) Master and use the professional knowledge learned in books to independently complete the detection and debugging of circuits

2. Componenets

1. The training device is built around an aluminum profile frame that includes a silk-screened panel to mount the components and a profiled base plate for easy installation.

The equipment chassis is equipped with castors with brake locks. Each system is fully installed with plumbing and electrical connections so that it is ready to operate.

Components are clearly laid out and labeled for easy identification, and refrigeration schematics and circuit schematics are provided to guide teaching.
The refrigeration pipeline is color-coded in red and blue. Red represents high pressure, and blue represents low pressure to indicate the state of the refrigerant. There is also a sight glass to monitor the cooling state of the refrigerant at this position. Refrigerant: R22 or equivalent.
