The invention provides a condenser heat dissipation control method, an automobile air-conditioning system and an automobile. The actual pressure in a high-pressure liquid pipeline correspondingly connected with a condenser is detected in real time; two heat dissipation mechanisms are reasonably controlled in combination with actual pressure; when the actual pressure is greater than or equal to a medium-pressure set value and less than or equal to a high-pressure set upper limit value, the first controllable heat dissipation mechanism is controlled to operate; when the actual pressure is largerthan the high-pressure set upper limit value, the first controllable heat dissipation mechanism and the second controllable heat dissipation mechanism are controlled to operate, the reliability of heat dissipation control over the condenser is improved, the heat exchange effect of the condenser and the refrigeration performance of an air-conditioning system are improved, and the phenomenon that acompressor intermittently works in a high-temperature environment is reduced or avoided.
本发明提供了一种冷凝器散热控制方法、汽车空调系统及车辆,实时检测与冷凝器对应连接的高压液体管路内的实际压力,结合实际压力对两个散热机构进行合理控制,当实际压力大于或者等于中压设定值、且小于或者等于高压设定上限值时,控制第一可控散热机构运行,当实际压力大于高压设定上限值时,控制第一可控散热机构和第二可控散热机构运行,提高了冷凝器散热控制的可靠性,而且提高了冷凝器的换热效果及空调系统的制冷性能,减少或避免了压缩机在高温环境中出现间断性工作的现象。
