  They’re really moving refrigerant. It’s just that the refrigerant keeps changing temperature (heating up at one end of the journey and cooling down at the other end).

    More specifically, we force it to undergo phase changes under different pressures, and in doing so it absorbs/releases latent heat in the air. It’s converting latent heat to sensible heat.
