Description
Technical field
The invention belongs to technical field of refrigeration equipment, particularly a kind of energy-saving whole compressor set.
Background technology
At present, energy-saving whole compressor set is to be generally single-stage vapor compression refrigeration system, is by refrigeration compressor, coldFour basic elements of character compositions of condenser, evaporimeter and choke valve, also comprise the direct current generator of the motor-driven work of drive compression, they itBetween connect successively with pipeline, form an airtight system, cold-producing medium constantly circulates in system, generation stateChange, carry out exchange heat with the external world. Its general principle is that liquid refrigerant absorbs the object heat being cooled in evaporimeterAfter amount, be vaporized into the steam of low-temp low-pressure, by compressor suck, be compressed into enter after the steam of high pressure-temperature condenser,In condenser to cooling medium (water or air) heat release, the system that is condensed into highly pressurised liquid, is low-pressure low-temperature through choke valve throttlingCryogen, again enter evaporimeter heat absorption vaporization, reach the object of circularly cooling. Like this, cold-producing medium process in system is steamedSend out, compression, condensation, four basic processes of throttling complete a kind of refrigeration cycle.
But in prior art, the quantity of the compressor connecting on direct current generator is one, and mode of operation is single, Bu NengshiWith the needs of various working pattern etc., practicality is not strong, and power consumption is large, can not accomplish preferably energy-conserving and environment-protective.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of energy-saving whole compressor set, this refrigerant compressionThe variation of device mode of operation, is suitable for various working pattern, is convenient to control, and its good refrigeration effect in addition, energy-saving and cost-reducing.
In order to realize above-mentioned technical purpose, the present invention realizes by following technical scheme:
A kind of energy-saving whole compressor set of the present invention, comprises housing, is placed in the direct current generator in housing, described inDirect current generator main shaft rear and front end correspondence is connected with two compressors, and in this two compressor, one of them is the compression of refrigeration outputMachine, another compressor that is compressed air output, between inlet end corresponding to two compressors by low-pressure connection tube road correspondenceConnect, on this low-pressure connection tube road, be provided with some throttle valve components; Two compressors pass through high pressure between corresponding outlet sideTube connector is connected with condenser and evaporator bank after connecting successively again.
As the further improvement of above-mentioned technology, on described low-pressure connection tube road, throttle valve component is two groups, described choke valveAssembly is connected in parallel and is formed by Multi-level throttle valve. Specifically: described throttle valve component comprises one-level choke valve and secondary jointStream valve, this one-level choke valve and two-step throttle valve are connected in parallel.
As the further improvement of above-mentioned technology, in described condenser and evaporator bank, between each evaporimeter, be all connected with electricityMagnet valve.
In the present invention, described evaporator bank is connected in parallel by multiple evaporimeters, and each magnetic valve correspondence is connected to each evaporimeterInlet end. Specifically, described evaporator bank is connected in parallel and is formed by four evaporimeters.
Described evaporator bank is connected in parallel by four evaporimeters, and magnetic valve correspondence is connected to the inlet end of evaporimeter.
In the present invention, the structure of energy-saving whole compressor set can be following two kinds of versions:
The first form is, described housing is full-enclosed structure, and the housing of this housing and front and back two compressors is in aggregates,Can make like this ownership cryogen in refrigeration compressing apparatus all in the space of a sealing, flow by pipeline.
The second form is, described housing is semi-enclosed structure, and the housing of this housing and front and back two compressors independently arranges,Be applicable to like this need strange land that the situation of compressor, direct current generator is installed.
In addition, in the present invention, described direct current generator is permanent magnet DC motor.
Compared with prior art, the invention has the beneficial effects as follows:
(1) the present invention respectively connects a compressor by the rear and front end of permanent magnet DC motor main shaft, and this two compressor passes throughThe control of magnetic valve, realizes two compressor series, parallel or works alone, and meets the demand of operating mode pattern not of the same race, heightImitate energy-conservation;
(2) in the present invention, compressor can be controlled by magnetic valve, makes the flow of refrigerant body in it can do suitable subtractingFew, thus the power of compressor reduced, and then reduce the power stage of direct current generator, make compressor output equivalentWhen refrigerating capacity, can reach the highest operating efficiency, power saving.
(3) in the present invention, when direct current generator main shaft drives forward and backward two compressor work, by solenoid control, canTo close the air inlet of one of them compressor, it is not worked, thereby reach not dissipation power, during according to the refrigeration of equivalent,Can be by circuit control, make compressor reach the object of optimized energy saving.
