The technical solution that the utility model proposes is to adopt the cold storage central air conditioner system of a kind of water, water knockout drum, a plurality of fan coils that link to each other with water knockout drum and the water collector that links to each other with refrigeration unit by return pipe that this system comprises a plurality of refrigeration unit that are arranged in parallel, links to each other with refrigeration unit by chilled water pipe, it is characterized in that: also comprise a water storage container in parallel with described refrigeration unit, this water storage container is a pressure vessel, and its pressure-bearing is greater than the terminal circulating pressure of user; Control the water storage container cold-storage and put cold frequency-converting control device according to user side varying duty demand with one.
In an embodiment of the present utility model, one in the described refrigeration unit for water storage container provides cold, and its water inlet end is provided with the elementary water pump that overcomes refrigeration machine and cold-storage container resistance.Described pressure-bearing water storage container can be vertical or horizontal putting, and inside is provided with water distributor.Described fan coil adopts accurate reverse-flow high-temperature blower coil pipe.
The cold storage central air conditioner system of repeatedly water that the utility model proposes is to be main purpose with the efficient that improves system, has concurrently and shifts the function of peak phase electric power to paddy phase, flat phase.Compare with other energy accumulation air conditioner and to have refrigeration and cold-storage efficient height, move electric weight and the electricity charge are few, reduced investment, occupation of land less, advantage such as operation maintenance is simple.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, wherein:
Fig. 1 is a system schematic of the present utility model.
The specific embodiment
As shown in Figure 1, water knockout drum 2, a plurality of fan coils 3 that link to each other with water knockout drum and the water collector 4 that links to each other with refrigeration unit by return pipe that the cold storage central air conditioner system of repeatedly water that the utility model proposes comprises a plurality of refrigeration unit that are arranged in parallel 1, links to each other with refrigeration unit by chilled water pipe, also comprise a water storage container 5 in parallel with described refrigeration unit 1, this water storage container is a pressure vessel, its pressure-bearing greater than user side circulating pressure and one according to user side varying duty demand control water storage container 5 cold-storages with put cold frequency-converting control device.
In the present embodiment, for user side, refrigeration unit 1 and accumulation of energy (water) container 5 be for being arranged in parallel, and one in the refrigeration unit for water storage container 5 provides cold, and its water inlet end is provided with the elementary water pump 6 that overcomes refrigeration machine and cold-storage container resistance.Water storage container 5 inside are provided with water distributor, and water storage container 5 can be vertical or horizontal placement, and the capacity of water storage container (5) makes the cold of its storage if emitted in one hour, can satisfy more than 30% of maximum load; The secondary water pump 7 of frequency-converting control device control satisfies the varying duty demand of user side.
Repeatedly the cold storage central air conditioner system of water is for the efficient that improves refrigeration machine with improve the accumulation of energy capacity, and its chilled water supply water temperature will be higher than the 3-5 degree of 7 ℃/12 ℃ of tradition, promptly 10 ℃/15 ℃ to 12 ℃/17 ℃ usually.Be the air quality (referring to humiture) after the assurance processing, user side easily adopts accurate reverse-flow high-temperature blower coil pipe or wind cabinet.
The utility model has adopted a pressure-bearing water storage container 5 in central air conditioner system, when the cold power of refrigeration machine was higher than customer charge, unnecessary part entered water storage container; When the cold power of refrigeration machine during less than customer charge, not enough part is replenished by water storage container, and repeat repeatedly every day.Make refrigeration unit have only 100% operation and 0% to shut down two states.So the efficient of central air conditioner system is all keeping efficient in the whole service phase.In addition, more the peak of implementing in conjunction with electrical network in some area, flat, the different charges of paddy electricity price can selectively drive refrigeration machine in flat, paddy phase and store cold, drive refrigeration machine less in the peak phase, not enough part is replenished by the cold in the water storage container 5, reaches the purpose of saving the electricity charge.
The utility model and traditional ice-storage type central air-conditioning are maximum different to be: repeatedly the cold storage central air conditioner system of water is to be main purpose with the efficient that improves the refrigeration system run duration, its operation power consumption is less than conventional air-conditioning, has the function that reduces electricity charge unit price simultaneously concurrently; Traditional ice-storage type, water storage type central air-conditioning are to be purpose to use night electricity to reduce electricity charge unit price, and its operation power consumption is more than conventional air-conditioning.Repeatedly the cold storage central air conditioner system small investment of water, take up an area of less, operational management is simple; Traditional ice-storage type central air-conditioning system investment is many, occupation of land is big, operational management is complicated.
For further system improves refrigeration machine efficient, repeatedly the cold storage central air conditioner system of water has also adopted accurate reverse-flow high-temperature blower coil pipe, make air quality do not change processing when the chilled water temperature that user side provides surpasses 3 ℃-5 ℃ of tradition (7 ℃/12 ℃) after, the thermal capacitance of pressure-bearing water storage container has also improved nearly 1 times.
During work, frequency-converting control device can according to user side varying duty demand control water storage container cold-storage and put cold, mainly contain cooling limit, limit cold-storage, cooling limit, limit put cold, single cold-storage, fully by accumulation of energy (water) container put cold, fully by 5 kinds of operating modes such as refrigeration machine coolings.And, can be according to the repeatedly electricity consumption Pinggu period that occurs in the daytime cold-storage repeatedly, as add electric heating system, can also finish corresponding accumulation of heat heat release function.
The utility model has following main feature when operation:
1. the system effectiveness height of multitime water cold-storage type central air-conditioning is embodied in the following aspects:
