Brief introduction to the cooling system
1. Both the HVW18 series are in-direct cooling single-system wine coolers.
2. A semi-conductor type cooling system is built into the unit. This system is also called
“Thermo-electric” cooling system; or “Peltier” system.
3. The core element in the system is a piece of special semi-conductor module. When a
direct current passing through this semi-conductor module, one surface of the conductor
becomes cold while another surface become hot.
4. General speaking, the temperature difference (the temperature ratio) between the 2
surfaces of the semi-conductor is a constant value. When the temperature on 1 surface
is changed, the temperature on another surface is changed respectively.
5. When the “semi-conductor” cooling element is applied onto the wine cooler, the cold
surface will be located inside the cavity of the cooler, and the hot surface will be located
at outside.
6. Both the “cold” side and the “hot” side of the semi-conductor equipped with a aluminium
radiator and a fan. Inside the cavity, the fans can help to provide a better air circulation
and to bring the air to draw the “cold” from the radiator. And; on outside, the fan can
help to diffuse or evaporate the heat on the “hot” aluminium radiator..
