Embodiment Construction

[0025] Such as figure 1 As shown, the cooling system comprises a reciprocating compressor 3 fed by an electrical power network 1 and having an electronic controller 2 able to control the operation of the reciprocating compressor 3 . The reciprocating compressor 3 drives the cooling gas in the gas circulation closed loop circuit 18 , thereby generating a cooling gas flow 78 within the circuit and directing this gas to the condenser 5 . After the condenser 5, the cooling gas passes through a flow cooling device 6, which may be, for example, a capillary tube. The gas is then directed to the evaporator 4 and then returned to the reciprocating compressor 3, restarting the gas circulation loop.

[0026] figure 2 Shows the focus of the subsystems inside the reciprocating compressor 3 formed by the housing 17 , the suspension spring 11 for damping the mechanical vibrations generated by the movement of the mechanical assembly 12 , the mechanical assembly is formed by a motor 9 and ...

Abstract

Control system for hermetic cooling compressor, which includes a reciprocating compressor and an electronic control (2) for the reciprocating compressor (3), the electronic control (2) being configured for, after commanding the turning off of the reciprocating compressor, detecting whether the turn velocity of the turning axle (10) is below a predefined velocity level, and then applying a braking torque that causes deceleration of the turning axle (10) before completing the next turn of the turning axle (10), in case the turn velocity detected is below the velocity level.

Description

technical field [0001] The present invention relates to a system and method enabling control of the stopping (braking) behavior of a reciprocating compressor. Background technique [0002] Reciprocating hermetic compressors include a connecting rod-crank and piston type with reciprocating motion, and are widely used in cooling equipment, domestic and commercial fields. [0003] Reciprocating compressors may be of the constant capacity type, where control of the two constant speed states (ON / OFF) is performed by switching the compressor on at maximum temperature and off at minimum temperature; or variable capacity Compressors, where the control is performed by some electromechanical device or electronic circuit capable of responding to a program dependent on a variable to be controlled (for example, the internal temperature of a compartment) on a cooling device, where The compressor functions in a reciprocating cycle of operation at varying speeds and when stopped. [0004]...
