About embodiment 9,
Figure 11 will possess the pie graph of the freeze cycle under the situation that gas-liquid separation device of the present invention is used for freeze cycle.
According to Figure 11, the formation of first freeze cycle under the situation that above-mentioned gas-liquid separation device 1 is used for freeze cycle is described.In freeze cycle pie graph shown in Figure 11,, marked necessary fundamental for present embodiment is described.
Promptly, compressor 20 has first cylinder 21 and second cylinder 22, the vapor phase refrigerant of the low-temp low-pressure that is sucked by compressor is by first cylinder 21 and 22 fens two stages of compression of second cylinder, become the HTHP vapor phase refrigerant, through cold-producing medium efferent duct 23, by condenser 24 heat release in the air of carrying with pressure fan 25 by condenser, become the high pressure liquid cold-producing medium.The liquid cold-producing medium is by 26 decompressions of first pressure reducer, become two-phase flow, flow into gas-liquid separation device 1 from two-phase flow inlet tube 9, after liquid phase refrigerant comes out from liquid phase outlet 7, enter into second pressure reducer 27, from by capturing heat the air of evaporimeter with pressure fan 29 conveyings, become the vapor phase refrigerant of low-temp low-pressure, and be inhaled into compressor 20.
On the other hand, because the vapor phase refrigerant of being separated by gas-liquid separation device 1 is inhaled into second cylinder 22 from gaseous phase outlet pipe 8, so, need not compress by the vapor phase refrigerant that does not help to evaporate that gas-liquid separation device 1 separates by first cylinder 21, compression power can be saved, high efficiency running can be carried out.
About embodiment 10,
Figure 12 will possess the second freeze cycle pie graph that gas-liquid separation device of the present invention is used for the freeze cycle different with Figure 11.
