High back pressure compressors

Hi everybody,
Can someone explain the 'High back pressure compressors"? What is the difference and how is the compressor construction?

Cheers.:)

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 Andy:)

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

Hi, guys! I convince "HBP" equal to "high evaporate pressure", but I don't consider "HBP" can be applied to "Domestic" range. Their application is different. And can a HBP be instead of a LBP??? It's impossible in most cases.
