The invention relates to an integral multifunctional electric air conditioning system for a crawler crane. The system comprises a compressor, a four-way reversing valve, an outdoor heat exchanger, anoutdoor fan, an indoor fan, an indoor heat exchanger, a hot water refrigerant heat exchanger, a first electronic expansion valve and a second electronic expansion valve; the second electronic expansion valve and the hot water refrigerant heat exchanger which are connected with each other are connected to two ends of the indoor heat exchanger in parallel, and the hot water refrigerant heat exchanger recovers heat from hot water of the engine compartment to integrally form double-heat-source refrigeration cycle. Compared with the prior art, the air conditioning system has the advantages of beinghigh in energy efficiency, compact in structure, convenient to install, high in system stability, capable of achieving a defrosting mode and an engine cooling mode, large in heating capacity, high ineconomical efficiency and the like, the defects of an existing traditional crawler crane air conditioning system can be well overcome, and the working efficiency of the whole air conditioning systemand a crane is improved.

    本发明涉及一种履带式吊车用整体式多功能电动空调系统,包括压缩机、四通换向阀、室外换热器、室外风机、室内风机、室内换热器、热水‑制冷剂换热器、第一电子膨胀阀、第二电子膨胀阀;相互连接的第二电子膨胀阀和热水‑制冷剂换热器并联于室内换热器两端,所述热水‑制冷剂换热器回收来自发动机舱热水的热量,整体上构成双热源制冷循环。与现有技术相比,本发明具有能效高、结构紧凑、便于安装、系统稳定性高、能够实现化霜模式、冷却发动机模式、制热量大以及经济性高等优点,能够很好的解决目前传统履带式吊车空调系统存在的不足,提升整个空调系统以及吊车的工作效率。
