As shown in Figure 5, shown in Fig. 5 is that a kind of natural energy that typically can adopt carries out the refrigerating plant cooled, it is a kind of split type structure, wherein, compressor 1, condenser 2, magnetic valve 3, choke valve 4, gas separator 5, refrigerant circulation pump 6, refrigerant reversing valves 7, natural cooler 8 are arranged in same framework, become a main frame.Each phase transformation sweat cooling end 9 is arranged on it independently in framework.Be connected with gas refrigerant pipeline 200 with liquid refrigerant pipeline 100 respectively between main frame and each phase transformation sweat cooling end.
Condenser 2 and natural cooler 8 are all a kind of finned coil heat exchanger be made up of copper pipe and fin, and wherein cold-producing medium is at copper Bottomhole pressure.The first cooling body and the second cooling body are all air.Cooling blower 10 drives between the fin of ambient air outside copper pipe and flows, and the heat of cold-producing medium passes to air in this way, and cold-producing medium is condensed into as liquid.
Compressor 1 adopts the magnetic suspension compressor of non lubricant oil, and cold-producing medium is cold-producing medium like R134a or other kind.
The operational mode of package unit is divided into complete compressor cooling, compressor cooling adds free cooling refrigeration, complete free cooling refrigeration three kinds of mode of operations.
The condition of work of complete compressor cooling mode of operation is that environment temperature is more than or equal to the refrigerant temperature ejected from phase transformation sweat cooling end discharge interface.Now, the passage entered between interface 71 and first row outgoing interface 72 of refrigerant reversing valves is opened, and enters the pathway closure between interface 71 and second row outgoing interface 73.Refrigeration compressor 1 is by the mode of compression, refrigerant compression is become the gaseous state of HTHP, enter in the middle of condenser 2 by refrigeration piping, the gaseous state cold-producing medium of HTHP is in condenser 2, transfer of heat arrived in air, the gas refrigerant condensation of HTHP becomes highly pressurised liquid state.The cold-producing medium of highly pressurised liquid state enters magnetic valve 3 and choke valve 4 by refrigerant tubing, the liquid refrigerant throttling expansion of high pressure becomes gas and the liquid mixture of low-temp low-pressure, the cold-producing medium of the gas liquid admixture of this part low pressure enters gas separator 54 by refrigeration piping, in gas separator 54, gas in cold-producing medium and liquid part separated, wherein gas fraction is discharged from the first row outgoing interface 51 of gas separator 54, by refrigeration piping, come back in the middle of compressor by compressor compresses from compressor refrigerant air entry 12.What the liquid refrigerant in gas separator 54 then entered refrigerant circulation pump 6 enters interface 61, refrigerant circulation pump 6 is by after this liquid refrigerant pressurization, pass through refrigeration piping, enter in 1 or multiple stage phase transformation sweat cooling end 9, the cold-producing medium of liquid condition absorbs the heat of cooled object in phase transformation sweat cooling end 9, evaporation becomes gaseous state cold-producing medium, from the discharge interface of phase transformation sweat cooling end 9, pass through refrigeration piping, passage between the inlet port 71 and first row outgoing interface 72 of refrigerant reversing valves 7, gets back in the middle of gas separator 54.In gas separator 54, this part refrigerant gas and foregoingly to be produced by throttling expansion and the refrigerant gas separated, pass through refrigeration piping together, enter the air entry 12 of compressor, again compressed by compressor, cold-producing medium goes round and begins again circulation like this, carries out the process of freezing.
The condition that compressor cooling adds free cooling refrigeration mode of operation is, environment temperature is less than discharges from phase transformation sweat cooling end 9 refrigerant temperature that interface ejects.Now, the pathway closure entered between interface 71 and first row outgoing interface 72 of refrigerant reversing valves 7, the passage entered between interface 71 and second row outgoing interface 72 is opened.Refrigeration compressor 1 is by the mode of compression, refrigerant compression is become the gaseous state of HTHP, enter in the middle of condenser 2 by refrigeration piping, the gaseous state cold-producing medium of HTHP within the condenser, transfer of heat arrived in the middle of air, the gas refrigerant condensation of HTHP becomes highly pressurised liquid state.The cold-producing medium of highly pressurised liquid state enters magnetic valve 3 and choke valve 4 by refrigerant tubing, the liquid refrigerant throttling expansion of high pressure becomes gas and the liquid mixture of low-temp low-pressure, the cold-producing medium of the gas liquid admixture of this part low pressure enters gas separator 54 by refrigeration piping, in gas separator 54, gas in cold-producing medium and liquid part separated, wherein gas fraction is discharged from the first row outgoing interface 51 of gas separator 54, by refrigeration piping, come back in the middle of compressor by compressor compresses from compressor 1 refrigerant suction mouth 12.What the liquid refrigerant in gas separator 54 then entered refrigerant circulation pump 6 enters interface 61, refrigerant circulation pump is by after this liquid refrigerant pressurization, pass through refrigeration piping, enter 1 or multiple stage phase transformation sweat cooling end 9, the cold-producing medium of liquid condition absorbs the heat of cooled object in phase transformation sweat cooling end 9, evaporation becomes gaseous state cold-producing medium, from the discharge interface of phase transformation sweat cooling end, pass through refrigeration piping, enter the passage between interface 71 and second row outgoing interface 73 from refrigerant reversing valves 7, enter into natural cooling heat exchange device 8.Now, because the temperature of air is lower than the gas refrigerant temperature entered, therefore, the transfer of heat of part gas refrigerant has arrived in the middle of air, be condensed into liquid, together with the gas refrigerant be not condensed, by refrigeration piping, enter interface 54 from second of gas separator 54 and get back in the middle of gas separator 54.In gas separator 54, the cold-producing medium having become liquid condition has been stayed in gas separator 54, cooled dose of circulating pump 7 is transported to phase transformation sweat cooling end 9 again together with other liquid refrigerant, the cold-producing medium of gas fraction is then produced and the refrigerant gas separated by throttling expansion 4 with foregoing, together by refrigeration piping, enter the air entry 12 of compressor 1, again compressed by compressor, cold-producing medium goes round and begins again circulation like this, carries out the process of freezing.Because a part is from phase transformation sweat cooling end 9 gas refrigerant out, in natural cooling heat exchange device, release a part of heat become liquid, therefore compressor needs again the air-breathing of compression cycle to reduce, and namely the live load of compressor reduces because there being free cooling refrigeration.
The condition of complete free cooling refrigeration mode of operation is that environment temperature is less than and discharges from phase transformation sweat cooling end 9 refrigerant temperature that interface ejects equally.Now, the pathway closure entered between interface 71 and first row outgoing interface 72 of refrigerant reversing valves 7, the passage entered between interface 71 and second row outgoing interface 73 is opened.When the ambient temperature is sufficiently low, from the gas refrigerant that phase transformation sweat cooling end is discharged, in natural cooling heat exchange device 8, total condensation becomes liquid condition, therefore, completely no longer needs compressor 1 to work, carries out pressure of inspiration(Pi) contraction SAPMAC method.
The above is the specific embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
