The conventional preheating method of dynamic ice cold-storage is that ice making pump discharge Duan Yin mono-road frozen water and cooling water carry out heat exchange in preheating heat exchanger, the frozen water being warmed after heat exchange flows back to ice making pump intake end again to be mixed with main pipeline frozen water, by the mode of this preheating, eliminate the ice crystal in water, the water of assurance low temperature does not contain ice crystal while entering heat-exchangers of the plate type.This preheating method is discharged in cooling water system the cold of frozen water when preheating, then is lost to atmosphere from cooling tower, and the cold of preheating is not directly utilized, and causes the loss of cold.
Utility model content
The purpose of this utility model, is to provide a kind of dynamic ice cold storage system of two kinds of preheating modes.
The solution that the utility model solves its technical problem is: the dynamic ice cold storage system of two kinds of preheating modes, it comprises cooling water pre-heating system, described cooling water pre-heating system comprises ice making pump, Ice Storage Tank, preheating heat exchanger, ice making unit, refrigeration host computer, chilled water pump, cooling tower, heat-riser valve and the first motor-driven valve, between the subcooled water conveyance conduit of described ice making pump and the cooling water pipe of refrigeration host computer, is provided with chilled water pre-heating system.
Further improvement as technique scheme, described chilled water pre-heating system comprises the second motor-driven valve being arranged between chilled water return pipe and preheating heat exchanger, be arranged on the triple valve between cooling water pipe, chilled water flow pipe and the preheating heat exchanger of refrigeration host computer, described triple valve import is connected with preheating heat exchanger, triple valve outlet is connected with cooling water pipe, and triple valve commutation mouthful is connected with the flow pipe of air conditioning water.
Further improvement as technique scheme, also comprises a controller, and the action of described heat-riser valve, the first motor-driven valve, triple valve and the second motor-driven valve is controlled by controller.
The beneficial effects of the utility model are: the utility model is by chilled water pre-heating system, directly utilize the frozen water of air-conditioning backwater and preheating to carry out heat exchange, system can regulate the flow of air-conditioning backwater for preheating according to the valve opening of the effect automatic regulating electromagnetic valve of preheating, thereby obtains the temperature of idle call cold water.The chilled water system that this preheating method directly uses air-conditioning the frozen water cold of preheating is used, and while having avoided carrying out preheating with cooling water, produces loss of refrigeration capacity, reaches energy-conservation effect.Pre-heating system can switch in cooling water pre-heating system and chilled water pre-heating system, if end air-conditioning is not used when ice-reserving, just switches to conventional cooling water preheating method.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe application of the present utility model in detail.
With reference to Fig. 1, the dynamic ice cold storage system of two kinds of preheating modes, it comprises cooling water pre-heating system, described cooling water pre-heating system comprises ice making pump 1, Ice Storage Tank 2, preheating heat exchanger 3, ice making unit 4, refrigeration host computer 5, chilled water pump 6, cooling water pump 8, cooling tower 9, heat-riser valve 10 and the first motor-driven valve 11, be provided with chilled water pre-heating system between the subcooled water conveyance conduit of described ice making pump 1 and the cooling water pipe of refrigeration host computer 5, and described chilled water pre-heating system comprises the second motor-driven valve 12 being arranged between return pipe and heat exchanger, be arranged on the cooling water pipe of refrigeration host computer 5, triple valve 13 between chilled water flow pipe and preheating heat exchanger 3, the import of described triple valve 13 is connected with preheating heat exchanger 3, the outlet of triple valve 13 is connected with cooling water pump 8, the commutation mouth of triple valve 13 is connected with cooling water pipe with preheating, also comprise a controller (not indicating in figure), described heat-riser valve 10, the first motor-driven valve 11, the action of triple valve 13 and the second motor-driven valve 12 is controlled by controller.
During the work of cooling water pre-heating system, in ice making operation process when the frozen water temperature that enters ice machine is lower than can eliminate the temperature of ice crystal time, heat-riser valve 10, the first motor-driven valve 11 is opened under the control of controller, system enters preheating operation, the cooling water that cooling tower 9 flows out enters preheating heat exchanger 3 through cooling water pump 8 pressurization rear portions, in preheating heat exchanger, carry out heat exchange with the low temperature frozen water that enters preheating heat exchanger through ice making pump 1 part, preheating backwater after heat exchange mixes with the entrance frozen water of ice making pump 1, reach preheating and eliminate the temperature of ice crystal, cooling water access coolant pump 8 inlet end of being lowered the temperature after heat exchange are mixed with supervisor's cooling water.The frozen water cold of this mode regenerator section is not directly utilized, but is discharged in cooling water system, causes loss of refrigeration capacity.
