The specific embodiment
Following examples will be further described the utility model in conjunction with the accompanying drawings.
Referring to Fig. 1～5, the utility model embodiment is provided with terminal air-conditioning box 1, refrigeration unit 2, heat exchanger 3 and water storage pool 4; Described terminal air-conditioning box 1 is communicated with refrigeration unit 2 by pipeline and the 1st valve S1, and described refrigeration unit 2 is connected with heat exchanger 3 with the 3rd valve S3 by the 2nd valve S2 respectively; Heat exchanger 3 is connected with refrigeration unit 2 with terminal air-conditioning box 1 with the 1st water pump M1 by pipeline, the 4th valve S4, the 5th valve S5, the 6th valve S6; Described water storage pool 4 is connected with heat exchanger 3 with pipeline by the 2nd water pump M2, the 7th valve S7, the 8th valve S8, the 9th valve S9, the 10th valve S10, realizes the heat exchange with refrigeration system.
Terminal air-conditioning box 1 is communicated with refrigeration unit 2 by pipeline, and forms terminal air-conditioning box refrigeration system by water pump and heat exchanger 3 and a plurality of valve.Cold accumulation system is communicated with by pipeline by water storage pool and water pump and valve and forms, by heat exchanger 3 and refrigeration system realization heat exchange.
Four kinds of cooling schemes are described below:
1. the direct terminad air-conditioning unit in refrigeration unit unit cooling
Under the normal cooling operating mode by refrigeration unit 2 direct terminad air-conditioning unit coolings.
Running: as shown in Figure 2, the 1st valve S1 and the 4th valve S4 are opening state, and the 1st water pump M1 opens, and other valves and water pump are closed.Cold water flows out from refrigeration unit 2 under the 1st water pump M1 effect, flow to terminal air-conditioning box 1 through the 1st valve S1, cold water air-conditioning box 1 endways flows to 1st water pump M1 through heat exchange through pipeline with outside air, under the effect of the 1st water pump M1, flow back to refrigeration unit 2 again and freeze, finish a cooling circulation.
2. simultaneously terminad air-conditioning unit and water storage pool cooling of refrigeration unit unit
When the electrical network electricity price is positioned at low ebb, and refrigeration unit 2 is less than meeting when operation, refrigeration unit 2 except terminad air-conditioning cooling also simultaneously to water storage pool 4 coolings, realize water storage pool 4 cold-storages.
Running: as shown in Figure 3, the 1st valve S1, the 2nd valve S2, the 4th valve S4, the 6th valve S6, the 7th valve S7, the 10th valve S10 are opening state, and the 1st water pump M1 and the 2nd water pump M2 open, other valve closings.Cold water flows out from refrigeration unit 2 under the effect of the 1st water pump M1, flows to the 1st valve S1 and the 2nd valve S2 respectively through piping, realizes shunting.The cold water of the 1st valve S1 of flowing through flows back to refrigeration unit 2 through terminal air-conditioning box 1 back by the 4th valve S4, finishes terminad air-conditioning box cooling; The cold water of the 2nd valve S2 of flowing through is undertaken becoming hot water after the heat exchange by heat exchanger 3 hot water with water storage pool 4, flows back to refrigeration unit 2 through the 6th valve S6 and the 4th valve S4, finishes to water storage pool 4 coolings.Water in the water storage pool 4 by flowing to the 10th valve S10 in the pond, flows through the 2nd water pump M2 and the 7th valve S7 under the effect of the 2nd water pump M2, carry out becoming cold water after the heat exchange through heat exchanger 3, flows back to the pond again, finishes a cold-storage circulation of pond cold-storage.
3. water storage pool auxiliary cooling unit freezes
When refrigeration unit 2 start refrigeration unit 2 overload operations, when not wanting to establish unit newly again, water storage pool 4 can freeze by auxiliary cooling unit 2, can avoid like this causing reserve unit frequent start-stop because cooling load changes, and effectively increases unit service life.
