Small and medium-sized large temperature difference dual-working condition dynamic fluid ice storage air conditioner

Abstract

The invention discloses a medium- and small-sized high-temperature-difference double-working-condition dynamic ice-slurry cold storage air conditioner. A refrigerating circulating device comprises a water cooling type evaporator and ice crystal devices, an air conditioning circulating device comprises an ice storage tank, and a water outlet of the bottom end of the ice storage tank is communicated with an ice making circulating pump and a flow meter sequentially; a pipeline of a water outlet of the flow meter is divided into two branches, water outlets of the upper ends of the ice crystal devices are communicated with the ice storage tank via first water outlet pipelines, a water outlet of the water cooling type evaporator is communicated with a water inlet of the ice storage tank via a second water outlet pipeline, one end of an ice melting circulating pipeline is communicated with an inlet of a sprayer, and the other end of the ice melting circulating pipeline is communicated with a second water outlet of the ice storage tank via a secondary heat exchanger. One end of an air-conditioner water inlet pipe is communicated with a third water outlet of the ice storage tank, and the other end of the same is communicated with a water inlet of an air-conditioner tail-end heat exchanger. One end of an air-conditioner water outlet pipe is communicated with a water outlet of the air-conditioner tail-end heat exchanger. The medium- and small-sized high-temperature-difference double-working-condition dynamic ice-slurry cold storage air conditioner can manufacture ice slurry for ice cold storage and can be used as a common air conditioner.

Description

technical field [0001] The invention relates to a new type of dynamic fluid ice storage air conditioner with large temperature difference and dual working conditions, in particular to a latent heat energy storage air conditioning system for producing frozen water and fluid ice, storing and melting ice. Background technique [0002] With the warming of the climate and the improvement of living standards, people's requirements for the summer environment are getting higher and higher, and the use of air conditioners is increasing, especially with the process of urbanization, the amount of air conditioners in large commercial facilities has increased dramatically. In the traditional central air-conditioning system, the chilled water of about 7°C is taken by the refrigeration machine and sent to the air-conditioning terminal equipment to enter the air-conditioning. This method is mature, simple and easy to implement, but this aspect is real-time refrigeration and air conditioning...

Problems solved by technology

Increasing the efficiency means that the energy storage density decreases; on the contrary, increasing the ice storage density can increase the efficiency, but it will cause a huge energy storage space

Second, because the stored ice is relatively large and hard, it is difficult to melt the ice quickly when needed.

Although this method has a high ice-making efficiency, the ice produced needs to be frozen in the ice storage tank, and the generated ice is very easy to form large ice cubes, and there is also an inherent weakness of poor ice-melting response

Furthermore, although it is dynamic ice making, its ice formation is static, so it cannot be directly used in air conditioning ducts

It is difficult to achieve large temperature difference air conditioning
