Refrigerant compressor driven by variable supply frequency motor |
摘要 |
A refrigerant compressor driven by an electric motor, whose supply frequency is selectively variable between a discrete number of values (f1, f2, fT) as a function of an input signal, uses control means integrated in the compressor to monitor two or more quantities that are variable with time in a mutually independent manner, of which at least one is representative of the actual operating conditions of the appliance. The control means also generates the input signal with a value that corresponds to a pre-established combination of the monitored quantities.
