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, by refrigeration compressor, condenser, evaporimeter and four basic elements of character of choke valve, formed, the direct current generator that also comprises the motor-driven work of drive compression, between them, with pipeline, connect successively, form an airtight system, cold-producing medium constantly circulates in system, there is state variation, carry out exchange heat with the external world.Its basic principle is after liquid refrigerant absorbs the object heat being cooled in evaporimeter, be vaporized into low-temp low-pressure steam, by compressor, sucked, be compressed into after the steam of high pressure-temperature enter condenser, in condenser to cooling medium (water or air) heat release, the cold-producing medium that is condensed into highly pressurised liquid, is low-pressure low-temperature through choke valve throttling, again enter evaporimeter heat absorption vaporization, reach the object of circularly cooling.Like this, cold-producing medium completes a kind of refrigeration cycle through pervaporation, compression, condensation, four basic processes of throttling in system.
But in prior art, the quantity of the compressor connecting on direct current generator is one, and mode of operation is single, can not be suitable for 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, a kind of energy-saving whole compressor set is provided, this refrigeration compressing apparatus mode of operation variation, applicable various working pattern, is convenient to control, and its good refrigeration effect, energy-saving and cost-reducing in addition.
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, comprise housing, be placed in the direct current generator in housing, described direct current generator main shaft rear and front end correspondence is connected with two compressors, in this two compressor, one of them is the compressor of refrigeration output, another is the compressor of compressed air output, between inlet end corresponding to two compressors, by low-pressure connection tube road is corresponding, connects, and on this low-pressure connection tube road, is provided with some throttle valve components; After connecting by high-pressure connecting pipe between outlet side corresponding to two compressors, be connected with condenser and evaporator bank successively again.
As the further improvement of above-mentioned technology, on described low-pressure connection tube road, throttle valve component is two groups, and described throttle valve component is connected in parallel and is formed by Multi-level throttle valve.Specifically: described throttle valve component comprises one-level choke valve and two-step throttle 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 magnetic valve.
In the present invention, described evaporator bank is connected in parallel by a plurality of evaporimeters, and each magnetic valve correspondence is connected to the inlet end of each evaporimeter.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, like this can be so that the ownership cryogen in refrigeration compressing apparatus all flows by pipeline in the space of a sealing.
The second form is, described housing is semi-enclosed structure, and the housing of this housing and front and back two compressors independently arranges, and is 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 is by the 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, and colleges and universities are energy-conservation;
(2) in the present invention, compressor can be controlled by battery valve, make the flow of refrigerant body in it can do suitable minimizing, thereby reduce the power of compressor, and then the power stage of reduction direct current generator, while making the refrigerating capacity of compressor output equivalent, 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 battery valve, control, can 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 controlled by circuit, make compressor reach the object of optimized energy saving.
