The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of cooling cycle system of automatic adjusting cold energy output, comprise compressor 1, condenser 8, reservoir 12 and at least one evaporimeter 11, the escape pipe 5 of described compressor 1 is connected with the air inlet pipe of described condenser 8, the drain pipe of described condenser 8 is connected with the input port of described reservoir 12, and the drain pipe 13 of described reservoir 12 is connected with the feed tube of described evaporimeter 11 by evaporimeter front end expansion valve 10; The escape pipe of described evaporimeter 11 is connected with the air intake duct 3 of described compressor 1, also comprises plate type heat exchanger 7, the first magnetic valve 4, the second magnetic valve 9 and the first expansion valve 6; The drain pipe 13 of described reservoir 12 is divided into two-way, wherein a road is connected with the first passage input port of plate type heat exchanger 7 with described the first expansion valve 6 through described the first magnetic valve 4, and described plate type heat exchanger 7 first passage delivery outlets are connected with the air intake duct 3 of described compressor 1; The blast pipe 5 of described compressor 1 is divided into two-way, and wherein a road is connected with the second channel input port of plate type heat exchanger 7 through described the second magnetic valve 9, and the second channel delivery outlet of described plate type heat exchanger 7 is connected with the input port of described reservoir 12.
Further, also can comprise control system, described control system can comprise pressure switch, described pressure switch detects air intake duct 3 internal pressures of compressor, when pressure switch action described in pressure of inspiration(Pi) is during lower than some setting values, send the first magnetic valve 4 and described the second magnetic valve 9 work described in signal controlling.
Workflow of the present utility model and operation principle:
Compressor head 2), the capital equipment such as condenser 8, reservoir 12, many evaporimeters the kind of refrigeration cycle of actual " drag many " comprises that (its nucleus equipment is compressor 1:, form a total cooling cycle system.Wherein each evaporimeter 11 is born respectively the refrigeration cool-down of a refrigeration space.Total refrigerating capacity of the refrigerating capacity of compressor 1 and many evaporimeters 11 matches.
The workflow of above-mentioned refrigeration system:
Refrigeration working medium (freon) gas enters condenser 8 by compressor exhaust pipe 5 after compressor 1 compresses, in condenser 8, refrigeration working medium is condensed into highly pressurised liquid and flows to reservoir 12 and stores, refrigeration working medium liquid in reservoir 12 carries out evaporative cooling through drain pipe 13, many evaporimeters 11 sent into respectively in different refrigerators by evaporimeter front end expansion valve 10 decompression, air intake duct 3 from evaporimeter 11 refrigeration working medium (having become low-pressure gas) out through compressor 1 is sucked and compresses by compressor 1, forms thus kind of refrigeration cycle process.
The utility model is on the basis of above-mentioned refrigeration system, set up 7 one of plate type heat exchangers, from reservoir 12 drain pipe 13 Shang Fen mono-road feed flow arms, the side that the first magnetic valve 4 through newly establishing and the first expansion valve 6 decompressions are supplied with in plate type heat exchanger 7 is carried out evaporative cooling, the refrigeration working medium gas after evaporating be connected to the air intake duct 3 of compressor 1, by compressor 1, sucked compression; Compressor exhaust pipe 5 Shang Fen mono-road exhaust branch pipes from compressor 1, the second magnetic valve 9 through setting up enters the opposite side in plate type heat exchanger 7, by the above-mentioned cooling of the feed flow from reservoir 12, be condensed into liquid, this liquid is connected to the input port of reservoir 12 and stores.
Like this, when refrigeration system is normally moved, be that between compressor 1 and evaporimeter 11, refrigerating capacity matches, two of connecting plate type heat exchanger 7 the first magnetic valves 4 of setting up and the second magnetic valve 9 are in closed condition, and this energy output self-checking device is not worked.
After refrigeration system operation certain phase, further minimizing along with refrigerator refrigeration duty, be that between compressor 1 and evaporimeter 11, refrigerating capacity does not match, there will be some situations, such as, the pressure of inspiration(Pi) of refrigeration unit is during lower than some setting values, pressure of inspiration(Pi) controller (pressure switch) can move, it controls two the first magnetic valves 4 of setting up and the second magnetic valve 9 energisings are opened, plate type heat exchanger 7 puts into operation, self-checking device is started working, make an energy part for compressor 1 output export to evaporimeter 11, and the automatic regulation output of another part energy is to plate type heat exchanger 7, when the pressure of inspiration(Pi) of refrigeration unit is during higher than some setting values, pressure of inspiration(Pi) controller (pressure switch) can move, and two the first magnetic valves 4 of setting up and the second magnetic valve 9 power-off are closed, and plate type heat exchanger is out of service, realize that between compressor 1 and evaporimeter 11, remain can amount phase equilibrium, solved above-mentioned compressor 1 because of the too low protectiveness autostop of pressure of inspiration(Pi), can make refrigeration system move continuously, make all refrigeration spaces can reach design temperature, meet the requirement of expection.
