Abstract
A medium supply apparatus includes: a storage part storing, in advance, information indicating a relation between a change in the amount of medium supplied by a medium drive part and a change in a frequency obtained by conversion in an inverter in accordance with a pipe resistance in a state that an electric motor is operated in a given condition; a frequency detection part detecting the frequency of the inverter in a case that the electric motor is operated in the given condition; a medium amount calculation part, on the basis of the frequency detected by the frequency detection part and the information stored in the storage part, calculating the amount of medium to be supplied by the medium drive part; a setup part setting up a necessary amount for the medium; and a frequency control part, on the basis of the necessary amount of medium set up by the setup part, the detected frequency, and the calculated medium amount, controlling the frequency to be obtained by conversion in the inverter.
