Abstract: In this paper,a new type of translucent photovoltaic thermoelectric refrigeration radiant window（STPV-TE-RCW）was studied on its thermoelectric performance through experimental and numerical simulation methods,and a CALCULATION model of STPV-TE-RCW was established to verify its accuracy. The different arrangement forms,radiation plate size and heat dissipation form of thermoelectric module in STPV-TE-RCW are optimized and analyzed. On the basis of considering the relationship between power generation and power consumption of the structure,through analyzing COP and power consumption of the refrigeration system,it is considered that the arrangement form of thermoelectric modules with 5 thermoelectric plates in series and 2 branches in parallel,the size of radiation plate with a height of 1 m and the heat dissipation form of forced convection are better. In this case,the ratio of power consumption to power generation of STPV-TE-RCW is 0.83,and the cooling capacity can bear 60% of the cooling load generated by the structure. The cooling capacity provided by the radiant aluminum plate is 63.4 W/m2,and the COP of the thermoelectric module is 1.41.
