Abstract
A method for regulating a fan in a compressor unit which having at least one compressor element, a motor connected to the compressor element, and a cooler including at least one radiator and a fan cooperating therewith; driven by a motor. The motor of the compressor element is driven at a speed varying as a function of it's a load and the number of revolutions of the motor of the fan is regulated as a function of a selected lever of cooling, thereby mitigating condensation of moisture by excessive cooling. The unit includes a speed regulation device connected to the motor of the compressor element.
Claims14
A method for regulating a fan in a compressor unit including a cooling circuit, at least one compressor element connected to the cooling circuit, at least one compressor element motor with electronically adjustable speed settings arranged to drive the compressor element, and at least one cooler connected to the cooling circuit and having at least one radiator and at least one fan cooperating, with the radiator driven by a fan motor, the method comprising the steps of:
- driving the compressor element motor at a speed varying as a function to a load;
- and
- regulating the number of revolutions of the motor of the fan as a function of a predetermined level of cooling in the cooling circuit, thereby mitigating condensation of moisture due to excessive cooling.
A compressor unit comprising;
- at least one compressor element;
- at least one compressor element motor arranged to drive the compressor element and controlled with a speed regulation device arranged to regulate the compressor element motor at a speed varying as a function of load on the compressor element;
- and
- at least one cooler including at least one radiator and at least one fan cooperating with the radiator and driven by a fan motor, controlled with a speed regulation device arranged to regulate the fan motor as a function of a predetermined level of cooling, thereby mitigating condensation of moisture due to excessive cooling.
