Variable air -conditioning central air -conditioning system training device

1. VAV is the abbreviation of Variable *r Volume. In the --r adjustment system, in order to cope with the changes in the end load, when the cold/thermal media flow is unchanged, it is necessary to adjust the --r volume to adjust the cold/calories. Transport to meet the needs of changes. VAV (variable --r-conditioning system) is a design standard by changing the amount of --r supply, "Specifications for Heating, Ventilation and *r Regulatory Design" (GBJ19-87-2003).

Overview

 

This device can meet the experiments requirements of "Motor Drag and Speed", "Electrology", "Vit Electric and Control System", "Electromechanical Transmission and Control", "Mechanical and Electrical Integration" and other test outlines requirements. The installation is novel, reasonable, and luxurious in appearance. It is suitable for new or expanded laboratories such as colleges, secondary majors, and vocational and technical colleges to quickly open experimental lessons to provide ideal experimental equipment.

 

1. Strong comprehensive: that is, the speed control control of the DC motor can be completed, and some "microcontrollers" experiments can be completed.

 

2. Strong complete set of completion: From the instrument, special power supply, motor, and other experimental components to the experimental connection line, it is complete.

 

3. The bottom plate of the motor guide r--ls uses a 20mm thick rolling steel plate. The motor runs the noise and never deforms. It ensures the long -term operation of the equipment.

 

4. The supporting small motors are specially designed, and their characteristics and parameters can simulate small and medium -sized motors. Students can deepen their understanding of motor theory through experiments.

 

5. There is a current -type leakage protection, which can be automatically protected by the overload or short -circuit of phase, lines, or short circuit.

 

6. The AC power supply uses an isolated transformer output. The experimental collection waveform is safer and reliable.

 

7. Timer and alarm recorder: It has a setting time, timely alarm, cutting off power, and records of various alarms.

 

1. Technical performance

1. Enter power supply: three -phase and four -line 380V ± 10% 50Hz.

2. Working environment: temperature -10 ℃ ～+40 ℃, relative humidity <85%(25 ℃).

3. Device capacity: <1.5kva.

2. Equipment composition

1. AC power supply (with flow protection measures, isolation transformer output)

Provide a three -phase 0-430V adjustable AC power supply, and at the same time, a single -phase 0 to 250V -adjustable AC power supply (with a three -similarities of the axis linkage device with a power of 1.5kva). The adjustable AC power output place has an overcurrent protection device. When the phase, the over -current between the lines, or the direct short circuit can be alarm and cut off the power. Equipped with three pointer AC voltage tables. By switching switches, the three -phase grid voltage and three -phase voltage voltage output voltage can be indicated, and there are indicator light indicating external power input and working power output. The AC power supply is output through isolation transformers. The tr--ning is safe and reliable to test the waveform.
