Description

A New Dynamic Ice Storage Air Conditioning System

technical field

The utility model belongs to the technical field of refrigeration, and in particular relates to a heat-absorbing refrigeration technology in which a refrigeration working substance is directly sprayed into water.

Background technique

With social progress and economic development, air conditioners have become an indispensable household appliance in people's lives. Especially in hot summer, air conditioners have become a necessity for people to improve their livable and comfortable environment. Therefore, air conditioners have also become the most power-consuming devices in families. With the popularization and use of air conditioners, the pressure on the national grid is increasing year by year. In order to alleviate the peak pressure of electricity consumption, the national power department has introduced and formulated peak and valley electricity prices and tiered electricity prices, but the results have been minimal. Peak electricity consumption has repeatedly hit records, and electricity supply and demand are tight. The situation is getting worse.

In order to realize the "peak shifting and valley filling" of the power grid and increase the load rate of the power grid, many experts and scholars have proposed ice storage air-conditioning systems. There are two main methods for ice storage air conditioning system to store ice and release cooling. One is to use static ice storage and indirect cooling technology. The air conditioning system has the advantages of stable cooling, simple structure, and low cost. Cold will not only cause energy waste, but also cause the refrigerant or refrigerant to freeze and expand to destroy the evaporator and the refrigerant. The other air-conditioning system adopts dynamic flow ice storage and direct release of cooling technology, which adopts dynamic flow ice energy storage and direct release of cooling technology, which has high stability, good cooling effect and excellent cooling efficiency, but the system design is complicated, the equipment requirements are high, and the investment cost High, suitable for large-scale cooling projects, such as large shopping malls, hospitals, schools, office buildings and other large centralized cooling buildings. Compared with ordinary compressed steam refrigeration and air-conditioning systems, the cooling efficiency of ice-storage air-conditioning systems is about 30% lower. Therefore, improving the cooling efficiency of ice-storage air-conditioning systems has become a research focus.

Contents of the invention

In order to solve the technical problem of low cooling efficiency of the ice storage air conditioning system, to improve the cooling efficiency of the ice storage air conditioning system and reduce investment and maintenance costs, and to ensure that the system can operate independently and stably, the utility model provides a new type of dynamic ice storage air conditioner system.

In order to improve the efficiency of ice-storage air-conditioning and reduce investment and maintenance costs, the technical solution of the utility model is to separate the dual-working unit of the traditional ice-storage air-conditioning system into a chiller cycle and a dynamic ice-making cycle with direct injection of working fluid. In order to improve refrigeration ice storage efficiency and save system investment and operation costs, the main innovation of this utility model is to integrate the evaporator of the chiller cycle, the condenser of the working medium direct injection dynamic ice-making cycle and the jet ice-making nozzle into the same water tank. It achieves high integration of cold water circulation cooling, direct injection of working fluid, dynamic ice making and user-side cooling.

A new type of dynamic ice storage air conditioning system provided by the utility model is mainly composed of a chiller cycle, a working fluid direct injection dynamic ice making cycle and a user-side cooling cycle. The chiller cycle includes a compressor 1, a gas-liquid separator 2, a condenser device 3, liquid storage device 4, electromagnetic valve 5, throttle valve 6, evaporator 7 and gas-liquid separator 8, and the working medium direct injection dynamic ice making cycle includes compressor 9, gas-liquid separator 10, condenser 11, Throttle valve 12, ice making nozzle 24 and gas-liquid separator 13, user side cooling cycle includes water pump 17, solenoid valve 18, check valve 19, proportional regulating valve 20, air conditioner 21, proportional regulating valve 22, solenoid valve 23 and The return water nozzle 25, the evaporator 7 of the chiller cycle is immersed in the cold storage tank 14 to produce cold water for cooling the user side and also for cooling the condenser 11 of the direct-injection dynamic ice-making cycle of the working medium. The condenser 11 of the direct-injection dynamic ice-making cycle of the working medium is also immersed in the ice storage bucket to absorb the cold produced by the circulating evaporator 7 of the chiller to reduce the pressure and temperature of the injected working medium. The ice-making nozzle 24 of the ice cycle is integrated in the cold storage tank 14 to be used for spraying, vaporizing, and absorbing heat of the refrigerant in the cold storage tank for refrigeration.

The beneficial effects of the utility model are: separating the traditional ice-storage dual-working condition unit into a chiller circulation and working medium direct injection dynamic ice-making cycle, so that the efficiency of cold water production and ice-making efficiency can reach the maximum at the same time, and the evaporation of the chiller circulation can be reduced. The condenser and the condenser and the nozzle of the direct injection dynamic ice-making cycle of the working medium are integrated in the cold storage box, which further improves the energy exchange efficiency and improves the ice-making efficiency, and also saves the cold water circulation pump and connecting pipes and other systems used for cold water transportation. components, reducing investment, operation and maintenance costs.
