Detailed description of the invention
Below in conjunction with embodiment, the present invention is elaborated.
A kind of negative pressure refrigerating method, it is characterized in that: cold-producing medium is placed in evaporimeter, with a negative pressure pump, gaseous, liquid mix refrigerant is extracted to upper end of evaporator cavity, a cooling reductor is sent after gaseous, liquid mix refrigerant being pressurizeed by negative pressure pump, cooling reductor is to the refrigerant cools of gassiness, and gas is overflowed from liquid state, liquid cold-producing medium sends into evaporimeter by flow-limiting valve.
Figure comprises evaporimeter 1, it is characterized in that: the top of evaporimeter is connected with a tube connector 2, tube connector connects a counnter attack cucurbitula 3, counnter attack cucurbitula connects the input of a liquor pump 5 by pipe 4, liquid delivery side of pump connects reduction cooling bath 6 input, reduction cooling bath output connects a counnter attack cucurbitula 8 by pipe 7, and counnter attack cucurbitula connects flow-limiting valve 10 by pipe 9, and flow-limiting valve connects the jet blower 11 being positioned at base of evaporator.Counnter attack cucurbitula is made up of the tank body 12 closed and turnover two tubes 13,14, and the bottom of inlet pipe is a long tube leading to tank base, goes out the bottom of pipe for being positioned at the short tube on tank body top.Counnter attack cucurbitula is positioned at a bosh 15.Reduction cooling bath is made up of cell body 16 and coil pipe 17 and drain pipe 18, the entrance point of coil pipe connects reduction cooling bath input, the end of coil pipe connects drain pipe, drain pipe lies in a horizontal plane on the bottom surface of cell body, drain pipe is densely covered with small through hole 19, reduction cooling bath output 20 is the long tube that a root bottom part is positioned at bottom cell body.Pipe between counnter attack cucurbitula and liquor pump is serially connected with check valve 21.Pipe between reduction cooling bath output and counnter attack cucurbitula is serially connected with check valve 22.
During work, fill with in bosh and have cooling water, cold-producing medium is marked with in reduction cooling bath, cold-producing medium is filled with in evaporimeter, the cold-producing medium of cold-producing medium alkanes, when liquor pump starts, the gas being positioned at evaporimeter upper space is drawn out of, cold-producing medium will evaporate under the environment of negative pressure, cold-producing medium is once evaporation of expanding, endothermic effect will be produced, the temperature of evaporimeter reduces, the cold-producing medium of the steam state of extracting out when then being started by liquor pump, enter into the long tube of counnter attack cucurbitula, the cold-producing medium of steam state is full of in counnter attack cucurbitula, then namely go out pipe from short tube and enter into liquor pump by pipe and check valve, due to the pressor effect of liquor pump, vapour-liquid mixed state is become after the cold-producing medium of steam state is pressurized, due to producing certain heat after pressurizes refrigerant, the cold-producing medium of the vapour-liquid mixed state after pressurizeing that therefore heats up enters reduction cooling bath, be passed in coil pipe by reduction cooling bath input, the cold-producing medium of vapour-liquid mixed state flows in coils, the refriger-ant section that its heat is reduced in cooling bath absorbs, and the cold-producing medium of vapour-liquid mixed state finally flow in drain pipe, the small through hole that drain pipe gathers is had to flow in reduction cooling bath again, with original refrigerant mixed, because the cold-producing medium of part steam state still contains a small amount of bubble when going out the small through hole of drain pipe, when therefore rising, diffusion heat absorption, so the cold-producing medium in whole reduction cooling bath remains in a cardinal temperature and can not heat up.Become liquid cold-producing medium due to low pressure, therefore it can toward evaporimeter flowing, middle through a counnter attack cucurbitula, then in counnter attack cucurbitula, cold-producing medium has cooling water temperature again, and the jet blower finally flowing into base of evaporator by flow-limiting valve enters in evaporimeter, flow-limiting valve is that the balanced recycle for ensureing cold-producing medium is arranged, to ensure how many cold-producing mediums are flowed out at evaporimeter top, the cold-producing medium with amount is just had to fill into from base of evaporator, to complete the long periodic duty of refrigeration.
