The specific embodiment
As shown in Figure 2, but a kind of balance is distributed the direct cool water supply cool-storage air conditioner system of refrigeration host computer and cold-storage groove output cold, comprise refrigeration host computer 1, cold-storage groove 2, air conditioning terminal 3, cold-storage pump 4, the cooling pump 5 of converting operation and electrically operated valve are formed, wherein, the import of refrigeration host computer 1 is connected with the outlet of cold- storage pump 4,1 outlet of refrigeration host computer is divided into two branch roads after connecting motor-driven valve V1, wherein, one the tunnel is the cold-storage branch road: the end of electric control valve V2 connects motor-driven valve V1, the other end is connected with the low import and export of cold-storage groove 2, and cold-storage groove 2 high import and exports are connected with the import of cold-storage pump 4; Another road is the cooling branch road: the two ends of electric control valve V4 are connected between the interface point in the interface point in described cold-storage loop and cooling loop and siphunculus 6 and cooling loop.
The outlet of cooling pump 5 is connected with air conditioning terminal 3, and the other end of air conditioning terminal 3 is connected with the import of cold-storage pump 4; Be provided with a connecting pipe 6 between cooling pump 5 aspiration ports and the air conditioning terminal 3 total return pipes, communicating pipe 6 is provided with electric control valve V3.
The low level of cold-storage groove 2 is imported and exported pipe and is provided with energy controller Q, with the cold of releasing of control, constant cold-storage groove 2, thus the cold preferential operation strategy of realization cold-storage groove 2.Energy controller Q is a cell cube of counting the basis with electronic flow, in good time out temperature that its in good time energy show value is a cold-storage groove 2 poor (Δ T=T2-T1) and the product that passes through cold-storage groove 2 in good time flows.
The principle following (dotted portion is the loop under each operating condition) of system's operation:
Refrigeration host computer cold-storage operating mode as shown in Figure 3, under this operating condition: motor-driven valve V1, electric control valve V2 open, refrigeration host computer 1,4 operations of cold-storage pump.When cold-storage temperature T 2 reached design temperature, cold-storage finished.
The independent cooling operating mode of cold-storage groove as shown in Figure 4, under this operating mode: electric control valve V2 opens, and electric control valve V3 and electric control valve V4 regulate according to cooling temperature T3, to keep constant cooling temperature.Cooling pump 5 always carries out variable frequency adjustment for the pressure reduction of return pipe according to the cooling loop, to reach energy-conservation effect.When putting cold temperature T 1 when reaching the temperature of setting, show that cold-storage groove 2 colds have discharged to finish, this operating mode stops.
The independent cooling operating mode of refrigeration host computer as shown in Figure 5, under this operating mode: motor-driven valve V1, electric control valve V3, V4 open.Refrigeration host computer 1, cold- storage pump 4,5 operations of cooling pump.Refrigeration host computer 1 unloads and loads according to its outlet temperature.
This pattern is equivalent to conventional secondary pump cold supply system, and cold-storage pump 4 is equivalent to backing pump, guarantees the operation of handpiece Water Chilling Units evaporimeter constant flow rate, moves under nominal situation to guarantee cold machine.Cooling pump 5 is equivalent to secondary pump, according to the external load converting operation, promptly always carries out variable frequency adjustment for the pressure reduction of return pipe according to the cooling loop.If cooling pump 5 flows are greater than the flow of cold-storage pump 4, then unnecessary flow is got back to 5 imports of cooling pump without refrigeration host computer 1 by bypass pipe 6.If cooling pump 5 flows are less than cold-storage pump 4, then the unnecessary flow of cold-storage pump 4 is got back to the import of cold-storage pump 4 by bypass pipe 6.
Refrigeration host computer as shown in Figure 6 and cold-storage groove associating cooling operating mode, under this operating mode: motor-driven valve V1 opens, and electric control valve V2, V3, V4 regulate.Refrigeration host computer 1, cold- storage pump 4,5 operations of cooling pump.
This operating mode can be divided into the preferential and two kinds of operation strategies of the preferential cooling of cold-storage groove of refrigeration host computer.
The preferential cooling strategy of refrigeration host computer is meant refrigeration host computer 1 with the external cooling of constant cooling amount, and insufficient section is released cold-patch by cold-storage groove 2 and filled.This operation strategy owing to cold refrigeration host computer 1 constant flow, by the Flow-rate adjustment of electric control valve V3, V4 and cooling pump 5, extracts cold-storage groove 2 inner cold waters in right amount and replenishes as cold, to satisfy the needs of external load down.
The preferential cooling strategy of cold-storage groove is meant the cooling amount Q control electric control valve V2 of cold-storage groove 2, makes the cooling amount of cold-storage groove 2 constant, and refrigeration host computer 1 satisfies the requirement of external load according to automatic unloading of its evaporator outlet temperature and off-load.
Cold-storage limit, refrigeration host computer limit cooling operating mode as shown in Figure 7, under this operating mode: motor-driven valve V1, electric control valve V2 open, and electric control valve V3, V4 regulate according to cooling temperature T3.The cold water part that refrigeration host computer 1 comes out enters cold-storage groove 2 and stores, and a part is carried out cooling through the outside air-conditioning system of cooling pump 5 inputs.This moment, the cooling amount of refrigeration host computer 1 should be greater than external load.
