So as Fig. 4, from refrigeration system schematic diagram of the present invention as can be known, this Crew Cooling System is divided into two and overlaps independently system, single cover system kind of refrigeration cycle is as follows: compressor sucks gaseous refrigerant at the low-temp low-pressure state from gas-liquid separator, through overcompression, then high pressure-temperature gas is delivered to condenser by blast pipe, here, because pressure condition, cold-producing medium is release heat towards periphery, becomes liquid state from gaseous state.Cold-producing medium leaves condenser with high-pressure liquid subsequently, through after liquid pipe magnetic valve, the device for drying and filtering drying to expansion valve.Expansion valve makes the high pressure phase of cold-producing medium to reducing, and has also reduced temperature simultaneously.Cold-producing medium draw heat the air in car, and then become gaseous state from liquid state again, get back to gas-liquid separator.Like this, kind of refrigeration cycle is promptly finished, will begin again to circulate from compressor next time.
After adopting the refrigeration system scheme in the foregoing description, integral trolley air conditioner of the present invention possesses following functional characteristics:
1) air vent mode:
Have only the ventilation blower running under this pattern, ventilation blower is provided with high and low two grades of wind speed, the size that can regulate the air-out air quantity as required.
2) refrigeration mode:
Under this pattern, air in a car compartment is sucked the air-conditioning unit by ventilation blower after the filter of return air inlet filters, finish refrigeration cool-down by evaporimeter, then, by ventilation blower treated air main air duct in car is sent to the guest room by air outlet again, the guest room is carried out air conditioning.
3) heating mode:
Under this pattern, air in a car compartment is sucked the air-conditioning unit by ventilation blower after the filter of return air inlet filters, and after the electric heater heating, sends to the guest room by ventilation blower again, and the guest room is carried out air conditioning.Temperature heats during for T-1 and opens, and temperature heats during for T+1 and closes.
4) new wind pattern:
New wind switch is divided into new wind, circulated air and automatic third gear, and new wind switch is set at " circulated air ", is that new wind closes; New wind switch is set at " new wind ", for new wind is opened; New wind switch is set at " automatically ", for new wind moves (opening 3 minutes in 30 minutes at interval) automatically.
5) fault alarm:
When high and low voltage switch 1 breaks down, close compressor 1 and liquid pipe valve 1, report to the police simultaneously (buzzer rings), and flicker shows failure code EP1.
When high and low voltage switch 2 breaks down, close compressor 2 and liquid pipe valve 2, report to the police simultaneously (buzzer rings), and flicker shows failure code EP2.
When temperature sensor is opened a way, close compressor and liquid pipe valve, and flicker shows failure code SoP.
When the temperature sensor short circuit, report to the police (buzzer rings), and flicker shows failure code SSH.
When dc source voltage is lower than 17V, close evaporation fan, condensation fan, compressor and liquid pipe valve, report to the police (buzzer rings), and flicker shows failure code ULo.
When dc source voltage is higher than 33V, close evaporation fan, condensation fan, compressor and liquid pipe valve, report to the police (buzzer rings), and flicker shows failure code UHI.
6) major loop control:
Two compressors, electrothermal tubes adopt the control mode of air switch (band earth leakage protective), A.C. contactor, thermal protector.Condensation fan, evaporation fan adopt the control mode of air switch (band earth leakage protective), A.C. contactor. Liquid pipe valve 1,2 and high-pressure side capacity control drive 1,2, low-pressure side capacity control drive 1,2, by-passing valve 1,2 is directly controlled by control panel.
