Heat pipes thermal performance for a reversible thermoelectric cooler-heat pump for a nZEB

The nZEB standards reduce the energy demand of these buildings to a minimum, obtaining this little energy from renewable resources. Taking these aspect into consideration, a thermoelectric cooler-heat pump is proposed to achieve the comfort temperature along the whole year. The same device can provi...
