Globally optimal control of hybrid chilled water plants integrated

The integration of thermal energy storage in chilled water systems is an effective way to improve energy efficiency and is essential for achieving carbon emission reduction. However, the commonly used large-scale thermal energy storage needs significantly larger space, which hinders the wide application of thermal storage in large number of existing buildings.

:,,, Abstract: Energy storage is one of the critical supporting technologies to achieve the "dual carbon" goal. As a result of its ability to store and release energy and significantly increase energy utilization efficiency, phase-change energy storage is an essential tool for addressing the imbalance between energy supply and demand.

Air Conditioning Clinic

This fluid is pumped through one or more ice storage tanks, where heat is transferred from the water inside the tank to the heat-transfer fluid. This causes the water inside the tank to freeze. When the thermal energy is needed at a later time, the heat-transfer fluid is again pumped through the storage tank, but now at a temperature above the
