As shown in Figure 1, also comprise for driving the first Cylinder Plunger device 111 of the first capacity regulating plate 11 movement in cistern 1, for driving the second Cylinder Plunger device 121 of the second capacity regulating plate 12 movement in cistern 1.Also comprise fluid clutch 4, to drive the first Cylinder Plunger device 111 and the second Cylinder Plunger device 121.
Under refrigeration energy storage pattern, the operation principle of the water storage system of the utility model embodiment is:
Cooling stages (such as during low ebb electricity price), accumulation of energy pond cold/heat source equipment 2 can be utilized to freeze to the water in the first sub-tank A1, be specially:
Controller N1 controls accumulation of energy pond cold/heat source equipment 2 and starts, and opens the second magnetic valve V2 and the 4th magnetic valve V4, closes the first magnetic valve V1 and the 3rd magnetic valve V3 closes.This evaporimeter 23 carries out upper water by the first watering pipeline being provided with the second magnetic valve V2 like this, water from the first sub-tank A1; After evaporator 23 cools, then turn back to the first sub-tank A1 by the first water return pipeline being provided with the 4th magnetic valve V4; So just can continue to utilize low ebb rate period by the water refrigeration in the first sub-tank A1 by connecting.Such as, can by the water cooling in the first sub-tank A1 to 5 DEG C.
And letting cool the stage (such as during peak electricity tariff), water in the first sub-tank A1 can let cool as the refrigerant of air-conditioning system 3, be specially:
Controller N1 controls air-conditioning system 3 and starts, and opens the 6th magnetic valve V6 and the 8th magnetic valve V8, closes the 5th magnetic valve V5 and the 7th magnetic valve V7.Now absorb water from the first sub-tank A1 that cold water is housed, then the water heated after refrigeration is transmitted back to the first sub-tank A1 again.When detecting that the return water temperature be provided with in the 6th magnetic valve V6 the 3rd water return pipeline is greater than preset value (such as 10 DEG C), then close the 6th magnetic valve V6 and open the 5th magnetic valve V5, the water of high temperature being transmitted back in the second sub-tank A2.The temperature of cold water rises for filling in the first sub-tank A1 of cold water can being prevented so too fast, improving recycling rate of waterused.
As can be seen from above-mentioned explanation, the utility model embodiment can energy storage in the given time, and exoergic in the given time.Based on identical principle, can also adopt and heat energy storage, and when peak electricity tariff by the pattern of air-conditioning system 3 heat release, not repeat them here.
Owing to letting cool the stage, air-conditioning system 3 can constantly in the first sub-tank A1 water freeze as refrigerant, then the water after temperature rising is transported to the second sub-tank A2.Therefore the water level in the second sub-tank A2 can continue to raise, and the water level in the first sub-tank A1 can continue to reduce.Now can control the first capacity regulating plate 11 by the first Cylinder Plunger device 111 mobile in cistern 1, increase the volume of the second sub-tank A2.Such as, can ensure that liquid level in the second sub-tank A2 and the first sub-tank A1 maintain an equal level.
As shown in Figure 1, the first capacity regulating plate 11 is provided with communicating valve 113, and communicating valve 113 connection control device N1.So just can open communicating valve 113 when needed, to make the aqueous phase intermodulation in the second sub-tank A2 and the 3rd sub-tank B join, balance the volume in the second sub-tank A2.
As shown in Figure 1, the first Cylinder Plunger device 112 drives the first capacity regulating plate 11 to move; Second Cylinder Plunger device 122 drives the second capacity regulating plate 12 to move.
Further, in order to the energy of avoiding waste, roughly can estimate the amount of letting cool required in second day, and determine to need to make how much cold water at cooling stages with this according to the position of building, function, the temperature, historical data etc. of second day in the utility model embodiment; Then drive the second capacity regulating plate 12 mobile in cistern 1, so that the volume of the first sub-tank A1 is adjusted to required cool water quantity by the second Cylinder Plunger device 121.
In the above-described embodiments, be by two capacity regulating plates, cistern is divided in order to three mutually isolated sub-tanks.As can be seen from aforesaid embodiment, the 3rd sub-tank B the 3rd sub-tank B is for regulating the first sub-tank A1 and the second sub-tank A2 institute water requirement to reduce energy waste; First sub-tank A1 and the second sub-tank A2 is for ensureing that the supply and return water temperature of air-conditioning system is in rational scope of design.
Accumulation of energy pond can be separated into multiple sub-tank by capacity regulating plate by the utility model embodiment, with two regions, ensure that the energy of air-conditioning system is supplied as required.Avoid and the water in whole pond is all processed, save the energy; Or, having the occasion in several ponds, avoiding the frequent number switching or increase and decrease pond.A distinguishes and is divided into A1 and A2 district by liquid level adjustable plate, ensure that the supply water temperature of air-conditioning system is all the time in the optimum temperature range of design, ensure that the comfortableness effect of air-conditioning system.Avoid with high investment, the inefficient way that layering dividing plate is set in whole pond.As control system, detection and control point position is few, and control logic is simple, is conducive to promoting the area application of the flat electrovalence policy of peak valley.The utility model is applicable to air conditioner refrigerating operation, heating operation.Also industrial circle or the other field of the energy requirement continuing to have is applicable to.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
