Refrigerator energy storage ice crystals

How ice crystals are made in a refrigerator?

In the process of making ice crystals, the refrigerator cools secondary refrigerant ethylene glycol to below 0 centigrade and then it is pumped to subcooler. The water at 0 centigrade is also pumped from ice- storage tank to subcooler after filtration and makes heat transfer with it.

What is ice crystal cool-storage air-conditioning system?

For ice crystal cool-storage air-conditioning system, because the ice crystal which produced in the ice-storage tank is very small and uniform with the diameter of about 100μm and can be directly pumped to participate in the refrigeration cycle at the load end, the system eliminates the need for secondary cooling medium and heat exchanger.

What is ice-storage air-conditioning technology?

Ice-storage air-conditioning technology is a kind of phase change energy storage. It makes use of the valley load electricity to make ice to storage cool at night and melt ice into water during daytime peak hours. It can release the amount of cool stored in the ice and supply cooling capacity to the load end with refrigeration unit.

What are the advantages of ice-crystal type ice storage air-conditioning system?

Ice-crystal type ice-storage air-conditioning system not only has the advantages of stable ice making and ice melting process and large energy-storage density, but also can save the storage space of the system and have a strong adaptability.It has good energy saving effect and economic benefit.

Why is ice storage important?

The ice storage provides the energy management ability to shift energy use to lower cost periods of time. Heat exchangers, located at each building, are often used to separate the distribution fluid from the build cooling loop.

How do ice storage systems work?

Like conventional chilled water systems, there may be seasonal changes initiated by a monthly date or ambient temperature. The ice storage control system may be interconnected to other large electric energy using equipment to provide energy management beyond just the HVAC components.
