摘要 The influence of the recycle effect on cool-thermal discharge systems in a parallel-plate channel with one side cooled by melting ice and the other side insulated is studied theoretically. The mathematical formulations are developed with moving boundary and the theoretical predictions are calculated using the integral boundary layer to estimate the required air mass flow and outlet chilled air temperature. Theoretical results show that the recycle operation can effectively enhance the heat transfer efficiency compared with that in the device without external refluxes. Numerical examples of inlet ambient air temperatures varied with time are illustrated to simulate practical systems from sunrise to sunset. The power consumption increment is also discussed.
