Description

one

The invention relates to the field of refrigeration and mechanical engineering and concerns compressors chillers ic and cold cooling of a condenser.

There are known methods of operation of refrigeration compressors for heating the refrigerant iB receiver to prevent (lowering the pressure of the three I134 condensation at their circulating air).

The aim of the invention is to increase the efficiency of the method of operation of the commission chiller.

This is achieved by the fact that the water heaters are heated: they are supplied from the compressor discharge line to the coil placed in the receiver, after which the pairs return to the refrigeration cycle on the suction side of the compressor.

In the drawing, the scheme of a press compressor chiller working but proposed method is punished.

The machine contains a compressor 1, a condenser 2, an evaporator 3. Between the condenser 2 and the evaporator 3, a reverse clan 4, a receiver 5 and a throttle device 6 are installed. In the receiver 5 a coil 7 is connected, connected by a conduit 5 with a solenoid valve 9 installed on it to the compressor compressor line /, and pipe 10 - to the suction side of the compressor /.

When the ambient air temperature is low, the solenoid-fan 9 opens and hot refrigerant vapors flow through pipe 8 into coil 7, causing an increase in pressure inside the receiver 5. The return valve KH 4 also lays in the flow of liquid refrigerant iB from the receiver to the 5 pressure coidensacin does not cause great pressure in receiver 5.

With this method of operation of the integrated cooling machine, there is no need for an additional energy source for heating the refrigerant in the receiver and the stability of the cold machine operation is increased due to the non-release of a part of the refrigerant. LOMP1MO evaporator IB (compressor lrn increased productivity of the latter.

Subject matter

The method of operation of the compressive cooling mannina when the coolant is heated in the receiver, characterized in that, in order to save energy, the heating is carried out with hot bunks placed in the receiver of the KOMHpeccojia injection line in the 1K kite placed in the receiver, in the receiver, in the receiver, after the pressure in the KOMHpeccojia injection line in the 1K, placed in the receiver, in the receiver, after the rest of the pressure line in the KOMHpeccojia injection line in the receiver, in the receiver, in the receiver, in the receiver, after the cooling line in the KOMHpeccoia injection line in the 1K, placed in the receiver, in the receiver, after the rest, after the cooling line . Cycle to the suction side of the compressor.
