The optimal cooling channel structure parameters S, H, L, and Q were determined to be 3 mm, 42 mm, 26 mm, and 0.04 kg/s, respectively. Compared to the original channel structure, this optimized structure resulted in a reduction of 13.7 % in T m and 20.3 % in ΔT m, significantly improving cooling performance.
To further enhance the cooling channel structure, an orthogonal experimental design was formulated based on the aforementioned research. Through the multi-objective optimization approach, the optimal combination of parameters is derived. 2. Numerical modeling
Thermal Energy Storage (TES) for space cooling, also known as cool storage, chill storage, or cool thermal storage, is a cost saving technique for allowing energy-intensive, electrically driven cooling equipment to be predominantly operated during off-peak hours when electricity rates are lower.
The batteries are arranged in the cooling channel, the spacing between adjacent batteries is set to 3.5 mm, the spacing between the channel wall and batteries is fixed at 4 mm, the size of the channel is 112 × 90.5 × 73 mm, and the inlet and outlet diameters, as illustrated in Fig. 1(b), (c), are both set to 6 mm.
Cool storage systems are inherently more complicated than non-storage systems and extra time will be required to determine the optimum system for a given application. In conventional air conditioning system design, cooling loads are measured in terms of "Tons of Refrigeration" (or kW’s) required, or more simply "Tons”.
Cool storage will reduce the average cost of energy consumed and can potentially reduce the energy consumption and initial capital cost of a cooling system compared to a conventional cooling system without cool storage.
