The specific embodiment
As shown in the figure, a kind of ice cold-storage air-conditioning system, comprise the Double-working-condition unit, eg pump 3, radiation recuperator 2 and Ice Storage Tank 1, described eg pump 3 drives ethylene glycol by the main line pipeline Double-working-condition unit of flowing through successively, return to eg pump 3 after Ice Storage Tank 1 and radiation recuperator 2, also comprise by valve I 8, valve II 9, valve III 10, the control system that valve IV 11 and valve V 12 form, described valve I 8 is arranged on the main line pipeline between Double-working-condition unit and Ice Storage Tank 1, described valve V 12 is arranged on the main line pipeline between radiation recuperator 2 and eg pump 3, the two ends of described valve III 10 are respectively by the main line pipeline communication at bypass line and Double-working-condition unit two ends, one end of described valve IV 11 is by the main line pipeline communication between bypass line and eg pump 3 and valve V 12, the other end is by the main line pipeline communication between bypass line and Ice Storage Tank 1 and radiation recuperator 2, one end of described valve II 9 is by the main line pipeline communication between the bypass line of bypass line and valve I 8 and valve III 10, the bypass line that the other end is connected on the main line pipeline between Ice Storage Tank 1 and radiation recuperator 2 by bypass line and valve IV 11 is communicated with.
The evaporimeter 4 of described Double-working-condition unit is connected into the main line pipeline, and the condenser 5 of Double-working-condition unit is connected in the cooling circuit consisted of cooling water pump 6 and cooling tower 7.
Mode of operation of the present invention has following several:
1) ice-storage mode
When low power consumption, open valve I 8 and valve IV 11, valve-off II 9, valve III 10 and valve V 12, now, ethylene glycol is in the rear release heat cooling of the evaporimeter 4 of the Double-working-condition unit of flowing through, thereby enter the interior absorption heat of Ice Storage Tank 1 again and make the water freezing in Ice Storage Tank 1 after valve I 8, the ethylene glycol after the absorption heat is got back to eg pump 3 after valve IV 11, and again participates in circulation;
2) ice-melt cooling pattern
When peak of power consumption, open valve I 8, valve III 10 and valve V 12, valve-off II 9 and valve IV 11, now, eg pump 3 orders about glycol flow and enters in Ice Storage Tank 1 through valve III 10 and valve I 8, and the ice in Ice Storage Tank 1 dissolves and absorbs heat the ethylene glycol temperature is reduced, and ethylene glycol carries out heat exchange absorption heat temperature with outside air and uprises through radiation recuperator 2 time, thereby room temperature is reduced, then get back to eg pump 3 participation circulations through valve V 12;
