Automatic Frequency thermal air-conditioning cooling system integrated laboratory equipment (computer presentation) with appraisal system

The equipment used variable frequency technology, the first single-phase AC power into DC rectifier bridge rectifier, and the three-phase inverter bridge to DC "inverter" arbitrary frequency-adjustable three-phase alternating current, automatic control of compressor speed, achieve the purpose of energy saving. Another new increase other types of air conditioners, refrigerators systems and more than 10 aircraft of the circuit, is conducive to the students to better grasp refrigeration heating technology. For the three-dimensional structure of the air-conditioning, front unit for indoor simulation, the rear is true outdoor unit, for real improvement of indoor air-conditioning unit components, jackets really transparent shell-wide air conditioning. Refrigerators also was improved, from around Georgia: refrigerated room for the front, behind the refrigerator compressor, studios, install temperature regulator. In order to overcome the refrigerators, air-conditioning temperature display, seventh-generation products has also increased the teachers fault presentation software, roving digital temperature display system testing, can be directly observed cooling and heating systems in the temperature of the key points.
Notable Features
1, lines absolute simulation. (Inverter on the market and the overall structure of air conditioning, performance is exactly the same as)
2, multi-point temperature acquisition, roving detection, digital display.
3, air conditioner - DC inverter using sophisticated technology to save energy, of teaching.
4, the overall design reasonable, compact, more open vision to the laboratory.
5, software and hardware integration, increase pilot project.
6, software-only virtual reality refrigeration, heating the entire process.
Skills Evaluation System Features
1, the computer can control 1-126 appliances intelligent assessment Taiwan
2, has set up more than 20 point of failure.
3, a function of volume
4, a function at volumes
5, a single, and the entire experiment, reset function Taiwan
6, with the automatic detection of communication appliances online assessment Taiwan situation
7, students can generate personal report card
8, student assessment can be conducted on statistical analysis of the
9, has entered the system password, the system can be modified to enter password
10, a printing function
11, a number of restrictions to answer function
Automatic Temperature Detection System
Automatic acquisition, roving detection, digital display)
1, the normal environmental temperature;
2, the compressor exhaust pipe;
3, compressor suction;
4, condenser exhaust port;
5, evaporator outlets;
6, compressor;
7, condenser;
8, evaporator.

New air-conditioning circuit sub-pilot projects Common Faults
First, do not work or work unit is not normal, fault can be demonstrated through the following
1, the microprocessor damage, fault code Q, should be replaced
2, crystal bad, fault code I
3, the CPU work +5 V power loss, fault code G
4, rectifier diodes damaged, not work, fault code F
5, three-terminal regulators 7812 bad, not work, fault code V
6, CPU reset bad, air conditioning did not work, fault code H
Second, indoor air, while the host does not work, through the following means troubleshooting.
1, such as the compressor can not work normally under normal circumstances: capacitance overload protection device circuit, overload protection device capacitance can be replaced
2, such as control orders error, fault code K
3, 12 V power loss, fault code V
Third, the normal work unit, remote control failure, can be demonstrated through the following methods
1, such as remote controls damage, fault code U
2, receiving the first bad, fault code P
3, the CPU bad, fault code P
4. Unit, remote control, healthy, and not faint buzzing sound, the following methods can be demonstrated
1, buzzer bad, fault code W
2,2003 integration damage, fault code X
V. unit, throttle non-action, fault code Y
6. Attention
1, the above fault demonstration by-case basis, demonstrated End should switch reset, the fault indicator light extinguished. Failure to carry out a demonstration.
2, normal, and all demonstrated switch forward (upward)
3, mainframe access, and shut down, time interval to five minutes or so, for a continuous activated easily damaged compressor.
4, the microprocessor installed delay protection three minutes.
5, cooling thermal conversion system downtime required in the state of 3 minutes more.
