High back pressure compressors

[lana]

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.

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.
