How to make a 220 v two wire outlet

I am moving back to Washington state from the Philippines and want to bring back some electrical appliances such as refrigerator, keezer, split aircon's that work on 220v two wire system. Our system here in the Philippines is one hot wire that is 220v and one neutral wire a two prong plugin. It's my understanding that in the U.S. a standard 220v line is two 110 lines a neutral and a ground. Is there any way I can bring a line out of the panel that would work with the 220v appliances that we have here? I do have transformers that say they can convert 110v to 220v two wire system but they are expensive to run and I've had them catch on fire so I would like to run it from the panel instead of using the transformer. Thanks

US voltage is 120v/240v not 220. Your refrigerator will probably be okay on 240v. The real question is is it 60 Hz. A quick google says the Philippines are 60 Hz. Verify that is true for your refrigerator and give us the voltage range on the label.

Yes it says 220 to 240 volt 50 or 60 hertz. Can the 240 volt come out on one wire so I have one 240v line, a neutral line and a ground? Most of my newer appliances are "inverter type" so they can run on fluctuating voltage without burning up.

This indicates you have inverter type. They don't use power your your outlet to drive motor/pump directly. Instead, they use inverter circuit to convert to DC then drives the motor/pump at variable speed with PWM. Therefore, it doesn't care about frequency of the power supply.
Not all inverter type appliances will support both 50Hz and 60Hz. But, from what google search returns, Philippines is 60Hz.

Can the 240 volt come out on one wire so I have one 240v line, a neutral line and a ground?
Not unless you use transformer to increase the voltage from 120V.
Your appliances will work fine with 2 hots. It will cause a problem only if the chassis is grounded through neutral and this is very rare these and those appliances will require polarized plug.

So when running two hots I would put the other hot where the neutral would be and then make sure everything is grounded?

You would need to install a 240 volt receptacle (NEMA 6-15R) and change the plug to NEMA 6-15P on the refrigerator.

You would install a 2-pole 15 amp breaker in the breaker box.
