PURPOSE:To shorten the period of time required to prevent the cold air from blowing-off at heating operation and the rise time at cooling operation by a method wherein a compressor is operated in a rotational frequency higher than the rated rotational frequency at the start of its operation. CONSTITUTION:Because the room temperature is higher than T1+DELTAT1 before starting the operation of the equipment, the rotational frequency (n) of the compressor is its maximum rotational frequency Nmax at its start. Because the room temperature gradually lowers in the meanwhile, the rotational frequency (n) of the compressor lowers and attains its minimum rotational frequency Nmin, which is followed by the standstill of the compressor, in one case or balances with a rotational frequency between the maximum frequency Nmax and mininum frequency Nmin, at which the compressor keeps on running, in the other case. |
