What do the numbers mean in TEC1-12706?
The “1” after TEC or TES indicates the number of stages in the device – 99% of all TECs are 1 or single stage. A two stage device would obviously have a “2”. The first three numbers after the dash are the number of Couples, such as “127” or “031”.
How do I choose a Peltier module?
- Draw horizontal line at 20 W on lower vertical axis which represents the power transferred through the Peltier module.
- Draw vertical line at 20°C on lower horizontal axis which represents the temperature difference maintained across the Peltier module.
How do you calculate Peltier efficiency?
Peltier cooling efficiency calculations
- input energy = 49.8 joules/second * 3600 seconds = 179,280 joules.
- energy used for cooling = 3.465 BTU * 1055 joules/BTU = 3655.58 joules.
- efficiency = 3655.58 / 179,280 = 0.02039 = 2%
Which is the hot side of a Peltier?
The object is cooled down to -5 °C in this case, by the cold side of the Peltier element. The hot side of the Peltier element is at 35 °C. The heat sink dissipates the heat to the surrounding air, which is at 25 °C.
What is a Peltier module?
Peltier module (thermoelectric module) is a thermal control module that has both “warming” and “cooling” effects. By passing an electric current through the module, it is possible to change the surface temperature and keep it at the target temperature.
What is the best Peltier module?

Why Peltier is not efficient?
Disadvantages of Peltier Systems Can’t provide low temperatures (below 10°C) Not very energy-efficient compared to compressor-based systems (although control technology means cooling can be more accurately measured than with a compressor, so these systems can be energy-efficient for small temperature gradients)
How long does a Peltier module last?
As discussed previously, the accepted industry standard for thermoelectric module MTBF is 200,000 hours minimum.
Can you make AC with Peltier?
Introduction: Mini Peltier Air Conditioner (Plans) This Instructable will show you how to make a environmental friendly portable air conditioner. This machine uses a Peltier Module as a cooling mechanism and some cooling fans for blowing air.
