Background
In order to make the system work stably in the traditional industrial refrigeration system, a single-body freezing water tank and two sets of water pump double-circulation open-type freezing water systems are generally adopted, the freezing water tank is generally a single space, the freezing water tank returns to the freezing water tank from a refrigeration unit for primary circulation, and the freezing water tank returns to an application end system for secondary circulation.
The traditional heating and water-ventilating air-conditioning system mostly adopts a single-circulation closed water system or a serial-type pressurization secondary circulation closed system, namely only one set of circulating pump and no water tank are adopted or a capacity-increasing closed tank is added, and the serial-type pressurization secondary circulation closed system is used for a high-lift water system without changing the original working property, namely a water pump is connected in series in a pipe network to play a role in segmented pressurization.
The two modes have certain inherent defects, for example, the single freezing water tank in the traditional industrial refrigerating system can cause the temperature of the freezing water supplied to the tail end application system to be higher than the outlet water temperature of the freezing water of the refrigerator, so that the efficiency of a refrigerating unit is influenced, and the defect of high energy consumption of a refrigerating main machine is caused; the open type circulating system can also cause the height difference of a circulating water pump to increase the pump head energy consumption of the water pump, and in addition, most of water can flow back to the water tank after the open type system pump stops working, so that the requirement on the volume of the water tank is higher; because of the adoption of a larger open water tank, a large amount of water resources and cold energy are wasted when equipment is maintained or is stopped for a long time.
The single-circulation closed system adopted by the traditional heating, ventilating and water-conditioning system ensures that the temperature of the water outlet of the unit is the temperature of the water for the tail end application system, and avoids unnecessary energy consumption of a host of the open system; meanwhile, because closed circulation is adopted, the circulating water pump does not need to consider the lift increased by the height difference, and the energy consumption of the pump is saved; the closed circulation does not need to consider the problem of water backflow after the water pump stops working; however, the traditional single-circulation closed system has a fatal weakness, the requirement on the load dosage constancy of the system is high, and if fluctuation occurs, the water flow of a host return machine is changed, so that the stability and the service life of a unit are influenced. In addition, the total water quantity in the system is small, the energy storage capacity is poor, the unit is easy to start frequently, the single-circulation water pump cannot synchronize the change of the tail end application system due to the influence of the operation of the main unit, the variable adjustment is not suitable, and certain waste is caused.
