Energy storage tube of water cooling system

What is thermal energy storage?

Thermal Energy Storage (TES) is the term used to refer to energy storage that is based on a change in temperature. TES can be hot water or cold water storage where conventional energies, such as natural gas, oil, electricity, etc. are used (when the demand for these energies is low) to either heat or cool the storage water.

How does a cooler supply water temperature work?

In both cases, warm water from cooling loads flows through the tank to melt the ice via direct contact, from outside-in. This permits a cooler supply water temperature to cooling loads and is especially applicable to district cooling applications where the cooler supply temp can reduce distribution pipe size and cost.

How does a cool storage system work?

Typically, a cool storage system uses refrigera- tion equipment at night to create a reservoir of cold material. During the day, the reservoir is tapped to pro- vide cooling capacity. There are many advantages to using a cool TES system.

What is a glycol fluid / chilled water heat exchanger?

A glycol fluid / chilled water heat exchanger will be used to separate the glycol and chilled water loops. The system will be a partial ice storage system. The design day cooling load profile has a cooling peak of 10.500 kW and a night cooling load of 11,000 kW to 1800 kW.

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.

Why is water a good cooling method for vessels?

Water is an ideal cooling method for vessels due to its excellent cooling capacity and space efficiency. “With liquid cooling the waste thermal energy can be reused for heating or transferred to sea water or to raw water system with a heat exchanger”, explains Teemu Alajoki, R&D manager at Adwatec.
