PROCEDURE FOR CONTROL OF REFRIGERATOR AND REFRIGERATOR WITH TIME DELAY OF COMPRESSOR TURNING ON Russian patent published in 2011 - IPC F25B49/02 

FIELD: machine building.

SUBSTANCE: refrigerator consists of compressor (2) with inlet orifice (11) of compressor and outlet orifice (12) of compressor, of evaporator (3) with inlet (13) orifice of evaporator and outlet orifice (14) of evaporator, of valve (4), of connecting pipes (5) and also of control unit (6). Compressor (2) and evaporator (3) are connected by means of connecting pipes (5) for working medium flowing thus forming a circuit of cooling agent, while valve (4) in circuit (7) of cooling agent is positioned between outlet orifice (12) of the compressor and inlet orifice (13) of the evaporator. Compressor (2) and valve (4) are controlled with control unit (6). Control unit (6) has device (8) of delay facilitating compressor (2) switching on only after valve (4) opening with a time delay. The invention also refers to a corresponding procedure of control of refrigerating aggregate (1).

EFFECT: reliable operation of refrigerating aggregate during phase of start up of compressor, high efficiency and power saving.
