The invention discloses a heating ventilation air conditioning system which comprises a box body, a PTC control module and an air blower. The PTC control module comprises a heating core body and a control box which are arranged in a separated mode and connected through a wire, the heating core body or the control box is independently taken out by disassembling the wire, and therefore the maintenance cost of the heating ventilation air conditioning system can be effectively reduced. An air return channel of the air blower comprises a first flow channel and a second flow channel which are arranged in a forked mode, the first flow channel is directly communicated with an installation space, where components are installed, in the control box, the second flow channel is directly communicated with a storage space, where a motor is installed, in the air blower, and external air can directly cool the components and the motor along the two flow channels. Compared with the prior art, the PTC control module has the advantages that an additional device for cooling the control box in the prior art can be eliminated, the manufacturing cost is saved, the components in the control box can be quickly cooled, the operation stability of the PTC control module is ensured, the maintenance and manufacturing cost of an automobile is saved, and the use safety of the PTC control module is improved.

    本发明公开了一种暖通空调系统,包括箱体、PTC控制模块和鼓风机。PTC控制模块包括分隔设置并导线连接的发热芯体和控制盒,通过拆卸导线将发热芯体或控制盒独立地取出,从而能有效减少暖通空调系统的维修成本;鼓风机的回风通道包括分岔设置的第一流道和第二流道,第一流道直接与控制盒内装设元器件的安装空间连通,第二流道直接与鼓风机内安装电机的存储空间连通,外界空气能分别沿着两个流道直接对元器件和电机进行冷却降温,不仅能消除现有技术中需额外对控制盒进行散热的装置,节省了制造成本,而且还能使控制盒内的元器件快速散热,保证了PTC控制模块运行稳定性,并节省了汽车的维修制造成本,提升了其使用安全性。
