[0020] As an improvement, the compressors are arranged on both sides of the evaporator box.

[0021] After the above technical scheme is adopted, the effects of the present application are as follows:

[0023] In summary, the double system air conditioner assembly is adopted, the refrigeration capacity or the heating capacity is greatly increased, the comfortable temperature in the vehicle is quickly achieved, the double system can be used simultaneously or singly, the use reliability is high, and the problem of affecting the use safety and the use life caused by overload operation is solved.

[0024] Due to the condensation water centralized discharge structure includes two bottom plates arranged at the bottom of the evaporator box body, each bottom plate corresponds to a refrigeration core body and a heating core body; the water collecting groove is formed by bending the bottom plate, the first water baffle is formed by bending the bottom plate on one side of the water collecting groove towards the fan, and the second water baffle is formed by bending the bottom plate on the other side of the water collecting groove towards the air outlet chamber; two ends of each water collecting groove are provided with drain pipes, and the two drain pipes at each end are communicated through a three-way pipe, so that the condensation water generated by the refrigeration core body during work is collected through the water collecting groove, and the condensation water is drained to other positions through the communication of the drain pipes and the three-way pipe; since the refrigeration or heating gas is blown by the fan, the condensation water is synchronously taken away, so the first water baffle and the second water baffle are used to prevent the condensation water from being blown into the air outlet chamber and the vehicle.

[0025] Due to the hollow structure of the pad is arranged in the water collecting groove, the bottom of the refrigeration core body abuts against the pad, and the periphery of the pad is provided with a water hole; the medium flow pipe on the refrigeration core body is vertically arranged, so that the condensation water naturally flows downward to the water collecting groove through the vertically arranged medium flow pipe, which is conducive to reducing the probability of synchronous blowing of the condensation water; the water hole on the pad facilitates the flowing water to smoothly enter the water collecting groove for discharge, and the structure is simple, which effectively improves the drainage effect.

[0026] Since the first and second water baffles are both formed by multiple bending, the second water baffle extends obliquely away from the heating core, and the second water baffle is further provided with a baffle that is folded back to the heating core, so that through multiple bending, the structural strength of the bottom plate can be improved, and the coverage area of the bottom plate for receiving condensed water can be increased, thereby further avoiding the problem that condensed water is blown into the air outlet chamber; through the obliquely extended second water baffle, the condensed water blocked by the second water baffle can slide down, and in cooperation with the baffle, the effect of blocking and buffering cold air or hot air is achieved, so that the cold air or hot air can enter the vehicle uniformly and gently, and the comfort is improved.

[0027] Since the positioning plate is arranged on the inner wall of the evaporator box at both ends of each refrigeration core, and the positioning groove for positioning the refrigeration core is arranged on the positioning plate, the mounting plate is arranged on the heating core, the plug-in plate is arranged on the inner wall of the evaporator box at both ends of each heating core, and the plug-in groove for positioning the mounting plate is arranged on the plug-in plate at the position corresponding to the mounting plate, so that the refrigeration core can be plug-in disassembled through the positioning plate with the positioning groove, and the mounting plate on the heating core can be plug-in disassembled through the plug-in plate with the plug-in groove, which is simple in structure and high in disassembly convenience and efficiency.

[0028] Since the bottom of the mounting plate is provided with a bent and formed connecting plate abutting against the bottom plate, and the length of the connecting plate is less than the distance between the two plug-in plates, the backflow groove is arranged on the mounting plate at both ends of the connecting plate, so that the abutment of the connecting plate and the bottom plate improves the stability of the mounting plate and the heating core thereon, and the length of the connecting plate is small, which does not affect the plug-in cooperation of the mounting plate and the plug-in plate; the backflow groove facilitates the flow of the condensed water blocked by the second water baffle to the water collecting groove.

[0029] Since the dust screen is arranged on the inlet and outlet air panel at the position corresponding to the inlet hole, the dust screen filters the gas entering the evaporator box through the inlet hole.

[0030] Since the hanger is arranged inside the shell, and the lifting lug extending to the outside of the shell is arranged on the hanger, the lifting lug and the hanger are cooperated to facilitate lifting during installation and removal of the dual-system air conditioning assembly (because the dual-system air conditioning assembly is heavy), which saves time and effort.

[0031] Since the condensers are arranged downstream of the air outlet chamber and are arranged in sequence, the distribution is reasonable and compact, and the space occupation rate is small.

[0032] Since the compressors are arranged on both sides of the evaporator box, the distribution is symmetrical and reasonable, and the stress is more uniform. BRIEF DESCRIPTION OF DRAWINGS
