Title:
COMPRESSOR CONTROL DEVICE FOR COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/111579
Kind Code:
A1
Abstract:
A compressor control device (19) for a cooling device, wherein a fixed rotational frequency is set for each set rotational frequency (rpm) for a compressor (10) for a cooling device corresponding to each temperature range (ΔD1, ΔD2, ΔD3, ΔD4) assigned until a target temperature (DEG0) is reached, and the set rotational frequency (rpm) is incrementally lowered in a pull-down process for cooling to the target temperature. In addition, at least one of the temperature ranges (ΔD1, ΔD2, ΔD3, ΔD4) is assigned by means of a function that is formed on the basis of the ratios (Rab, Rbc, Rcd) of cooling performance parameters (Va, Vb, Vc, Vd) corresponding to each set rotational frequency (rpm).
