    TX-2002A7-type Inverter air conditioner cooling heating

    comprehensive experimental equipment (seventh



     Seventh-generation cooling heating laboratory equipment using frequency conversion techniques, first single-phase AC power supply through the rectifier bridge rectifier into DC, but also by the three-phase inverter bridge to DC "inverter" into the three-phase AC adjustable frequency of random, Automatic compressor speed to achieve energy-saving purposes. Also new to add other types of air-conditioning, refrigerator system and the circuit more than a dozen models will help

    students to better grasp the cooling system of heating technology. Split air-conditioning for the three-dimensional structure of the simulation in front of indoor unit, the rear for the simulation of outdoor units, indoor units to improve as a true air-conditioning components, air-conditioning fully transparent shell jacket really.

     Refrigerator also has been improved, before and after the cell separation: in front of the freezer, followed by the refrigerator compressor, studio, and installation of the temperature regulator.

     In addition, in order to overcome the refrigerator, air-conditioning temperature display problems, seventh-generation products has increased the detection circuit digital temperature display system, can be visually observed cooling and heating system, the temperature of each key point.

     1. Significant features:

    1. The overall structure of inverter air conditioner, line, performance,

    control method and inverter air conditioner on the market entirely


    2. Multiple-point temperature collection, road detection, digital


    3. Pure DC inverter air conditioner uses cutting-edge technology,

    saving energy, the expense of teaching.

    4. The overall design is reasonable, compact, so that laboratories and

    better visibility.

    5. Software and hardware combination can increase the pilot project.

     6, with a pure software simulation of refrigeration, heating the entire process.

     2. Temperature and ground survey system features:

     Temperature Circuit detection system can detect the refrigerators and split air conditioner temperature critical points.

     A. Can detect the key points are:

    1. Normal ambient temperature

    2. Air-conditioning compressor exhaust pipe

    3. Air-conditioning compressor back to the trachea

    4. Air-conditioning condenser air vents

    5. Air-conditioning evaporator air outlet nozzles

    6. Refrigerator Compressor

    7. Refrigerator Condenser

    8. Refrigerator Evaporator

     B. Basic operations:

     Cooling heating system to work, click the "temperature ground survey" unit bottom left of the green indicator light on the button below to make the green indicator light, temperature and ground survey system to start. At this time the key point temperature measurement.

     This system has an automatic reset function, when the testing is completed, after a few seconds delay, the system will automatically reset.

     3. Examination system features:

    1. The computer can monitor 1-126 Taiwan inverter air conditioning

    heating intelligence assessment units.

    2. Have set more than 10 point of failure. (And can extend the

    point of failure)

    3. Has the function of fat volume.

    4. A winding function.

    5. Papers with a single function and all the papers cleared Clear


    6. With auto-detect the inverter air conditioner cooling heating

    intelligent assessment of Taiwan's communications online.

    7. Can generate transcripts of individual students.

    8. Student assessment can be carried out statistical analysis.

    9. Can have access to the system password and change your


     10, with printing functions.
