Experimental performance evaluation of a convective thermoelectric building envelope for building heating and cooling

The thermoelectric building envelope (TBE) integrates materials with the for active space heating and cooling. advantage of TBE cooling includes its significantly low-profile design no refrigerant use. Although there are existing studies evaluating performance, they were based on limited operating conditions. study aims to experimentally evaluate performance a prototype under various was installed between two psychrometric chambers, which simulated indoor outdoor tested at an temperature around 22.35–23.58 °C temperatures from −7.35 16.99 28.36 40.95 cooling, varied power inputs fan maximum coefficient (COP) in mode is 3.2. average COP current 1.5 A four winter scenarios 1.37. 0.3–1.5 12 2.27. system demonstrates better efficiency than auxiliary electric heater heat pump system. experimental results evaluation obtained provide critical guidance deployment applications.
