A lot has been mentioned, on various threads, about the effects of low-side pressure drops.

For example:
1. TXV orifice size;
2. Distributor & capillary tubes;
3. Evaporator;
4. Suction line & fittings.

What effect does the high-side pressure drop (compressor discharge to TXV inlet) have on overall RHVAC system performance?

What are acceptable high-side pressure drops?
