electric cabinet cooling

[Lc_shi]

Hi sirs

How about the application of thermoelectric air conditioner to the cabinet cooling? Is it more reliable than compressor refrigeration system ?

anybody can share me some information here? thanks in advnce

Hi Lc shi
It really depends on the application and load size. Thermoelectric is drastically less efficient than vapour compression. If it is for something like a humidor (small to medium) then it's OK. It is reliable and simple to control with electronics, hence reliable. So for small loads it's cool - but not for bigger loads.

Hi LC SHI ,as tesla says thermoelectric is far less efficient. a good example are the small plug in car fridges, runs 4 amps on 12 volts all day to cool about 10c below ambient where a compressor driven car fridge running 4 amps can cool around four times the space and cycle at 30c below ambient.

thanks for your information. I'll look for the compressor system.

I have worked on plenty of the Rittal units and they are pretty good.

they are very good and so are these http://polak.co.il/_Uploads/269AirAir.pdf

Cabinet coolers use a vortex tube that converts compressed air into cold air to cool.So cooling can be done easily.

A waste of energy.
To receive 1 KW of work from compressed air, you will need 8 KW electricity!!!!

Most electric boards use refrigerants as cooling substance. Mainly R-134a.
