Description
Technical field
The invention belongs to refrigeration air-conditioner and ice storage technology field, relate in particular to a kind of structural design of ice smelting and cold storage device in parallel mono heat exchanger.
Background technology
Ice-chilling air conditioning system is to utilize electrical network cheap electric power such as the night electricity of low-load period, and the cold of refrigeration system being produced by refrigerating medium (being generally glycol water) is stored in the water, water congeals into ice; And, the cold in the ice is discharged to the air-conditioning system cooling, thereby reduce the electrical network high load capacity phase to the demand of electric power, the air-conditioning system of realization power system " peak load shifting " on the electrical network high load capacity phase such as the daytime of electricity price costliness.In the area of power shortage, ice-storage system even can realize " load shift "---the refrigeration duty of time period of unregulated power supply is transferred to the supply of electric power period, improved the scope of application of refrigerated air-conditioning system.Therefore this technology has been subjected to the support energetically of the electric power policy of user's welcome and power department, is developed rapidly at home.
Interior ice melting system is a kind of of ice-storage system form.In the process of cool of interior ice-melt cold accumulation system, the low temperature refrigerating medium enters in Ice storage coiled pipe or the ice hockey jar, draw the heat of water in the outer or ice hockey of coil pipe and improve self temperature and flow out hold-over coil or ice hockey jar, simultaneously, coil pipe survey outward or ice hockey in the water release heat and be condensed into ice.In the cold process of getting of interior ice-melt cold accumulation system, the refrigerating medium of high temperature enters in the coil pipe or the frozen water release heat of ice hockey jar in the coil pipe outside or ice hockey, becomes the low temperature refrigerating medium and flows out Ice Storage Tank; Simultaneously, the ice draw heat thawing that coil pipe is outer or ice hockey is interior is water.Interior ice melting system is because storage density of cold is big, and control method is simple, and factors such as security of system height are occupied significant proportion in all ice cold-storages are used.
In the prior art, interior ice melting system is divided into the different of heat exchanger quantity according to the type of attachment and the coolant pump of ice groove and cold machine: the single pump (Fig. 1) of contacting, polyphone double pump (Fig. 2), mono heat exchanger in parallel (Fig. 3) and double heat exchanger in parallel system forms such as (Fig. 4).
The polyphone single-pump system since the restriction of system performance can't be implemented in the process of cool simultaneously by cold machine provide little load cooling requirement (if by force during the cold-storage to outside cooling, because entering the heat exchanger refrigerant temperature is lower than 0 ℃, and flow is uncontrollable, so the coil pipe bursting by freezing takes place easily), promptly can't realize the operating mode of confession while holding.Therefore, provide the system of cold if desired during cold-storage, then need to be provided with separately the cold machine of base load to meet the demands, this will largely reduce the investment yield of system in the very little system of base load load.In addition, adopt in the ice-storage system of the single pump of polyphone, refrigerating medium still needs the refrigeration unit of flowing through when the independent cooling operating mode of ice groove, and this has increased the energy consumption of coolant pump system to a certain extent.But this system form is still recommended and is extensive use of in actual engineering, chief reason is: in existing in the ice melting system form, minimum (1 (group) pump of auxiliary element in this system, 2 (group) magnetic valves, 2 (group) motor-driven valves), system cost reduces relatively, and causes control method simple relatively thus.
Polyphone double pump system form is the improvement to the polyphone single-pump system.By increase by one (group) at the heat exchanger loop thus coolant pump and a bypass line are realized the confession operating mode while holding.Refrigerating medium has increased the resistance of system still by cold machine when cold but this system gets separately at the ice groove.In addition, owing on the bypass line magnetic valve or motor-driven valve are not set, increase the difficulty that system regulates and controls, and might cause the direct bypass of system's cold water, caused waste.Simultaneously, owing to increased (group) pump in the system, increased the initial cost and the operating cost of system to a certain extent.Therefore, this kind system form uses seldom in the practical application.
Comparatively speaking, parallel system can realize that all cold accumulation system comprises 5 kinds of operating conditions of the confession while holding.The system of parallel connection double heat exchanger system adopts the ice groove to get cold loop and the cold loop separated structures of cold mechanism, though make the control of cold accumulation system become relatively simply clear, but it has increased complexity and system's initial cost of system pipeline greatly, so less use in the actual engineering.Mono heat exchanger system in parallel causes unit operation when different mode owing to adopt polyphone double pump structure, and every responsible resistance object of pump all changes, and causes great difficulty for the control of cold accumulation system, has reduced the stability of control system simultaneously; Simultaneously, if the resistance of system has bigger variation under the different mode, then need to adopt speed-variable pump, this has improved the initial cost of system again.Based on this, the also less in practice use of existing mono heat exchanger system in parallel.
Summary of the invention
Purpose of the present invention and task are on the basis that keeps former mono heat exchanger system advantage in parallel, a kind of novel ice smelting and cold storage device in parallel mono heat exchanger is provided, unite cooling, supply 5 kinds of operating modes while holding to realize cold-storage, ice groove cooling, cold machine cooling, the cold machine of ice groove, simplify mono heat exchanger system control method in parallel simultaneously, improve the stability of control system; Further reduce system cost and energy consumption thereof.
