Re: High back pressure compressors
Hi Lana
high back pressure usually refers to domestic compressors, larger motor for starting.
In screws a different volume ratio is used, and with piston compressors, more valve spring pressure is usually used.
Kind Regards AndyIf you can't fix it leave it that no one else will:rolleyes:

Re: High back pressure compressors
Hi Lana...to repeat what Andy said, HBP is normally a term applied to Domestic/small Commercial (Hermetic) compressors.
They are designed to cope with a higher evaporating temperature and are not so dependant upon the cooling effect from the return suction gas.
You can use a HBP compressor in place of a LBP but not the other way round.
If you look at the specifications you will see the HBP is evaporating at about +7 deg C and the LBP is at -25deg C.
Hope this helps...regards Adrian
