The invention provides a vehicle heat management carbon dioxide heat pump air conditioner heat exchanger giving consideration to refrigeration and heating, a system and a control method.According to heat exchange, n on-off adjusting structures are arranged in a first main collecting pipe and a second main collecting pipe correspondingly, and by controlling the on-off states of the 2n on-off adjusting structures, the on-off states of the 2n on-off adjusting structures are adjusted to be the same as the on-off states of the 2n on-off adjusting structures; the 2n + 1 areas of the heat exchange channel can be in a series connection circulation state or a parallel connection circulation state, so that the circulation distance of a refrigerant in the heat exchanger can be changed, and the circulation distance of the refrigerant in the heat exchanger can be changed according to refrigerating and heating working conditions; the requirement for the heat exchanger structure in order to achieve better performance under the refrigerating and heating working conditions can be considered at the same time, the refrigerating performance of the heat exchanger under the refrigerating working condition is improved, and meanwhile the heating performance under the heating working condition is improved.
本发明提供一种兼顾制冷制热的车辆热管理用二氧化碳热泵空调换热器、系统及控制方法,所述换热,在第一主集流管和第二主集流管中分别设置n个通断调节结构,通过控制2n个通断调节结构的通断状态,能够使换热通道的2n+1个区域为串联流通状态或并联流通状态,从而能改变制冷剂在换热器中流通的距离,进而能根据制冷制热工况改变制冷剂在换热器中流通的距离,能同时兼顾制冷制热工况下为达到更加优良的性能对换热器结构的要求,提升在制冷工况下换热器制冷性能,同时提高在制热工况下的制热性能。
