Method for controlling reciprocating piston compressor of refrigeration system, involves controlling temperature of cooling location, and converting manipulated variable into switching signal for clocked opening and closing of valves

摘要

The method involves measuring and evaluating temperature in a compressor (1). Temperature of a cooling location (6) is controlled by switching on and switching off operation of a motor when temperature in the compressor exceeds an upper temperature threshold. The temperature of the cooling location is controlled by a continuously switching on operation of the motor when the motor is cooled up to a lower temperature threshold. A manipulated variable is converted into a switching signal for clocked opening and closing of valves (7) by a controller. An independent claim is also included for a refrigeration system.
