Main regulating object adjusts GV01 for temperature occurred frequently using flue gas triple valve, and low hair temperature uses jacket water triple valve GV02 tune
It is whole.The adjustment of flue gas triple valve is better than jacket water triple valve.
More specifically, after 100 full-load run of internal combustion engine generator, cylinder sleeve coolant-temperature gage such as (is less than flue gas at 95 DEG C or so
452 DEG C of temperature), the refrigeration energy to lithium bromide refrigerator 200 can only be adjusted as the auxiliary thermal source of lithium bromide refrigerator 200
Power influences less but can influence the stable operation of internal combustion engine generator 100, so its triple valve GV02 apertures are preferentially adjusted to maximum,
As stablize heat source and do not allow its participate in 100 refrigerating capacity of internal combustion engine generator regulation and control.
Wherein, flue gas is supplied as 100 main heating source of internal combustion engine generator, reaches rated value in 100 power of internal combustion engine generator
Afterwards, the regulation performance of triple valve (GV01) determines the refrigeration stability of lithium bromide refrigerator 200.It is set in one-key start scheme
During meter, the pid parameter of flue gas triple valve is continued to optimize, regulating power can match the cold negative of lithium bromide refrigerator 200
Lotus changes.It should be noted that flue gas triple valve GV01 buying when must have regulation performance, and use be arranged vertically for
Preferably, it must assure that the useful space is left at its top in design process.
Specifically, cooling load controls auxiliary regulating object that reduction generator load, application of load may be employed for load shedding
It may be employed and improve afterburning valve increasing firing optimization.Auxiliary therrmodynamic system is led in internal combustion engine generator 100 and lithium bromide refrigerator 200
