Prospects of sustainable photovoltaic powered thermoelectric cooling in zero energy buildings: A review

“…Luo et al 62 studied the building integrated photovoltaics thermoelectric system (BIPV‐TES) with battery system for application in building air‐conditioning and concluded that such system can provide savings by saving 72% to 92% energy in cold region, 88% to 100% in mixed zone, and 100% in cooling dominant zone, compared with a massive wall as a reference. Zhang et al 63 studied standalone PV‐powered TEM system for water heating application for remote houses and concluded that the system is economically feasible with payback of 2.2 years in Lhasa city for operating current of 1.8 A. Garayo et al 64 recently studied the actual application of PV‐TES HVAC system in 74.3 m 2 passive house in Pamplona, Spain and reported a COP of 1 to 2 for heating and 0.5 to 1.7 for cooling. They concluded that although a conventional VCR technology based heat pump (COP of 2.5 to 4.5 for heating and 2.2 to 4 for cooling) provides faster cooling, the PV‐TES system can be economical and viable alternative for low energy demand (10 W/m 2 ) buildings like passive houses, which already incorporate energy efficiency measures.…”

“…This will need devices with sufficient COP of 2 to 3, which fits well in the scope of present TEM research level systems. Even with current technology, recent studies like References [64,65] demonstrate the technical and economic viabilities of such systems in low energy demand buildings, which still rely on conventional air‐conditioning. Recent studies like Reference [66] inspire potential improvement scope in the optimization of the TEM operating parameters for achieving better COP.…”

Efficiency Enhancement Strategies for Water-Source Thermoelectric Heat Pump Modules

“…The device has improved the average COP compared to previous systems and has shown significant energy-saving and emission-reduction benefits.S. Díaz de Garayo 19 proposed a sensible heat recovery HVAC system to further reduce the energy consumption gap with vapor compression heat pumps, and it can be combined with photovoltaic panels to further reduce energy consumption. This indicates that thermoelectric technology has broad prospects for application in passive building HVAC systems.Jiang et al 20 proposed a novel, practical, and commercially valuable integrated water-cooling cycle thermoelectric distiller for alcohol distillation.…”
