Theoretical study on the nonlinear change characteristics of the glide temperature with the enthalpy and the temperature glide of R236fa/R32 mixed refrigerant which used in variable evaporation temperature refrigeration system; Establish the calculation model and judging method for pinch points and the maximum temperature difference of the mixed refrigerant R236fa/R32 in heat exchanger; Determine...
As an important part of urban public transport, how to reduce energy consumption of rail transit becomes a focused issue. Considered with the operating characteristic of air conditioning in subway station, solution method with large temperature difference and high outlet temperature of 10/17 Celsius in evaporator is put forward. Two condensers and evaporators are linked in series and both of them...
