Can you change the ordinary car air conditioner into home use? How much voltage power do you need, DC or AC? starting circuit ...

I can tell you for sure that it is almost impossible under the current technical conditions. The reason for this is the following：

The refrigeration capacity of automobile air conditioner is very small, which is mainly used for the refrigeration of narrow space in the carriage. Any room in the house is more than 20 square meters, and this amount of cooling capacity doesn't work at all.

The compressor of automobile air conditioner is driven by automobile power, and the compressor of household air conditioner is driven by civil alternating current. Therefore, the automobile air conditioner compressor can't work at home. Of course, you can also use it forcibly, install an AC motor yourself, and drive the motor through household electricity, which will drive the compressor. Barely able to work

The battery power supply used in the blower of automobile air conditioner works at DC voltage of 12- 16V, and the 220V AC power supply on household air conditioner can't drive the blower at all. Of course, you can also forcibly drive it, rectify 220V AC into 12V DC through AC -DC conversion (this is probably the reason why many household air conditioners fool DC inverter air conditioners now) and then drive the blower to work.

The air duct and air conditioning box of the car are designed according to the specific structure of the car body. If used at home, it can be used as a fixed fan and can be ventilated.

The condenser fan of automobile air conditioner is also DC, which is similar to a blower and can't be turned on at home. It is equivalent to the outdoor unit of household air conditioner.
