This application relates to air conditioning technology, and more particularly to a vehicle air conditioner. It includes a housing, a return air connection channel, left and right cooling units, and an outlet air connection channel. The housing has a left system air inlet channel and a right system air inlet channel; the first air inlet end of the return air connection channel is connected to the left system air inlet channel, and the second air inlet end is connected to the right system air inlet channel; the air inlet end of the left cooling unit is connected to the first air outlet end of the return air connection channel; the air inlet end of the right cooling unit is connected to the second air outlet end of the return air connection channel; the first air inlet end of the outlet air connection channel is connected to the air outlet end of the left cooling unit, the second air inlet end is connected to the air outlet end of the right cooling unit, the first air outlet end is connected to the left system outlet air channel, and the second air outlet end is connected to the right system outlet air channel. This utility model can not only simultaneously perform independent temperature control on two independent load heat sources, but also achieve redundancy compensation and powerful cooling control functions, improving the reliability of the vehicle air conditioner and its applicability to complex scenarios.

The invention discloses a chair seat with a waist movement function, which comprises a seat support internally provided with a cavity structure for accommodating parts, at least one group of driving assemblies internally mounted in the seat support, a seat plate positioned right above the seat support and operated by the driving assemblies to perform corresponding actions, and a control module internally mounted in the seat support and used for controlling the movement of the waist. The control module is used for controlling the driving assembly to operate according to corresponding settings so as to drive the seat plate to incline to pull the waist to move; the seat plate can be driven by the driving assembly to incline so as to pull the waist to move, and waist discomfort caused by long-time sitting is effectively relieved.
