Abstract

The invention discloses a refrigerant filling method for a thermosyphon oil cooling refrigeration system. The thermosyphon oil cooling refrigeration system is filled with a refrigerant by adopting filling equipment mainly composed of a refrigerant container, a distribution station, a main pipeline and three distribution pipelines; a refrigerant inlet valve is arranged on the main pipeline, and thedistribution station is provided with a first refrigerant outlet valve, a second refrigerant outlet valve, a third refrigerant outlet valve and a pressure gauge; the first refrigerant outlet valve, the second refrigerant outlet valve and the third refrigerant outlet valve are sequentially connected to a pipeline between an evaporator and a low-pressure circulating liquid storage device, a pipeline between a condenser and a thermosyphon liquid storage device, and a pipeline between a high-pressure liquid storage device and a throttle valve through the three distribution pipelines correspondingly; and one end of the main pipeline is connected to the refrigerant container, and the other end of the main pipeline is connected with the distribution station. The refrigerant filling method has the advantages that the filling equipment which is simple in structure and convenient to operate is adopted, safety and reliability are achieved, the procedure is clear, and the filling efficiency is high.

Description

technical field [0001] The invention relates to the technology in the field of refrigeration systems, in particular to a refrigerant charging method for a thermosiphon oil cooling refrigeration system. Background technique [0002] At present, refrigeration systems are generally divided into thermosiphon oil cooling and water cooling. Thermosiphon oil cooling uses the pressure difference formed by the difference in density between liquid and gas to circulate, without pumps and other conveying equipment. Compared with water cooling, thermosiphon oil cooling can save water source, and can avoid fouling in the heat exchanger and affect heat transfer, so it is widely used. [0003] Such as figure 1 As shown, the thermosiphon oil cooling refrigeration system 5 includes a condenser 501, a thermosiphon liquid reservoir 502, a high-pressure liquid reservoir 503, a throttle valve 504, a low-pressure circulating liquid reservoir 505, a refrigerant pump 506, an evaporator 507, a compr...
