초록 ▼

The invention concerns a method for speed control of a compressor, particularly a refrigeration compressor, and a control arrangement using this method. The speed control is effected in that a control arrangement varies the speed of an electric motor in dependence of simple ON/OFF signals from a thermostat placed in the surroundings to be cooled. The method according to the invention is characterized in that the starting speed of the compressor in a following ON period is reduced in relation to the final speed in the previous ON period. A continuous reduction of the starting speed of each ON period results in a self-regulating control giving long compressor operation times and an averagely low speed resulting in energy savings. A control arrangement using this method is also described.

대표청구항 ▼

[ What is claimed is:] [1.] Method for controlling motor speed in a compressor used in cooling an area such as a room, the compressor having an electronic control arrangement, which, from a thermostat having ON and OFF states, receives a signal depending on the temperature in the room to be cooled, and the compressor having a variable starting speed, the method comprising the steps of reducing the starting speed in a subsequent ON period in relation to the final speed in a previous ON period by making the control arrangement subtract a predetermined speed from the final speed in the previous ON period and using the result of this calculation as the starting speed in the subsequent ON period, and during the ON period either increasing or keeping the speed constant.
