The refrigeration units take their power from the locomotive.
To really understand how air conditioner removes heat? You have to know thermodynamics second law: " heat always flows from a material at a high temperature to a material at a low temperature." There're so much to it! AC condenser unit is the components that removes the heat in air conditioner. You also have to understand the other AC four basic components to know how and why it removes heat.
