Description
Technical field
This application involves technical field of refrigeration equipment, in particular to the control method and system of a kind of water cooler.
Background technique
In the related technology, two stage centrifugal compressor is widely used in centrifugal water chillers, in this centrifugation cooling-water machine
In group, economizer (or saving function device) is usually provided with after a nuclear one-stage throttling device, refrigerant liquid passes through a nuclear one-stage throttling device
It throttles shwoot (that is: rapid evaporation), gas-liquid two-phase cold-producing medium enters in economizer shell through input pipe, part of refrigerant
Liquid continues to flash in economizer shell, and flash gas enters compressor gas supplementing opening by blowdown pipe, reduces compressor two
Grade gasinlet temperature improves compressor efficiency to increase mass flow.Unevaporated refrigerant liquid is by outlet tube stream
Out, evaporator sweat cooling is entered after second throttle, increases the refrigerating capacity of unit, lower power consumption reaches energy-efficient purpose.
For two stage centrifugal water cooler, since unit efficiency is more sensitive to first order throttling, generally for the machine of raising
Group all the period of time operational energy efficiency, centrifugal chiller lesser for energy generallys use electric expansion valve or analog quantity electric butterfly valve carries out
First order auxiliary adjustment to adjust cold medium flux, and then realizes Load Regulation；For second level throttling usually then using fixation
Orifice plate, reason is primarily to reduce control difficulty, while also in that second level throttling is not so good as the first order to the variation of load
It is sensitive.In unit actual motion, especially under high pressure ratio, the operating condition of Smaller load, second level orifice plate at this time then can be bigger than normal, leads
The pressure of economizer is caused, i.e., superfeed pressure reduces, namely reduces the pressure ratio of the centrifuge first order, increases the centrifuge second level
Pressure ratio；Under normal conditions, for centrifugal compressor, the second level is due to pneumatic design characteristic and second level air flow inlet
It organizes poor, causes air-flow to be easier to flow back in the second level, i.e. compressor surge, to limit the operation model of compressor
It encloses.Therefore, high pressure ratio, in the case where Smaller load, using the form of fixed orifice plate, it will limit the range of operation of compressor.
However, most of centrifugal refrigerating machines are all made of the adjustable throttling of level-one, second level then uses the form of fixed orifice plate.
Second level throttling also adjustable unit is then mostly used using suction superheat as target component, this is for making full use of container
It gets a promotion for ability, but in view of under certain operating conditions, user needs unit work in big compression ratio, small negative
When under conditions of lotus, unit, which is then likely to occur, at this time to unload, or unit operation is expanded by introducing hot-gas bypass
Range, and hot-gas bypass can drastically reduce unit operational energy efficiency.In view of finding in practical applications, for double-stage compressor,
More first there is surge phenomenon (gas flow counterflow) in second level pneumatic structure (second level impeller+diffuser+spiral case), and the first order is pneumatic
Structure (first order impeller+diffuser+return channel etc.) air current composition is also relatively good, at this time if according to liquid level or suction superheat
Spend the control of the electric expansion valve of simple target, the then reality of first order compressor when being likely to occur second level pneumatic structure surge
Running pressure ratio, there are also larger surpluses apart from its surge pressure ratio, and therefore, compressor operating frequency range is restricted, and in part
The small energy consumption of load is higher.
