Refrigeration Heating Air Conditioning la

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.

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.
