Review on Hilitand Semiconductor Refrigeration System Radiator by Kory Shelton

Revainrating 5 out of 5

It "CAN " cool or heat, but the device worked as expected to cool the air with running water.

This review is for the six-chip version. I think it's well made with quality components. The fan is a bit noisy, which is my only (though minor) complaint. FYI Peltier devices have a complex relationship between differential temperature and supply current. These devices are not the most efficient at their maximum currents and have many criteria to keep them efficient. With the test rig I built today I believe this unit will do the job for my purpose of cooling 12 35Ah SLA batteries in a barn where the ambient temperature reaches 90 degrees Fahrenheit. without air conditioning. With the Peltier units connected to the 3S2P and about 12V - 18V applied to them, the supply air easily reaches 55 degrees at an ambient temperature of 72 degrees at the radiator. I believe I can achieve a 20 degree difference which will take me below 80 degrees. Power consumption isn't too bad at 80-120W, which is much lower than that of an air conditioner. (I bought another one after a few hours of work.)

Pros
  • Internal components
Cons
  • Questionable purchase for the elderly
