I should have included that tid-bit in my first post. The high side reading corresponds with the 404a at room temperature, but the low side pressure corresponds with the 404a being well below freezing. 1.1 Purpose. The purpose of this standard is to evaluate and accept/reject refrigerants regardless of source ( i.e., new, reclaimed and/or repackaged) for use in new and existing refrigeration and air-conditioning products as required under 40 CFR part 82. 1.1.1 Intent.

Re: 404A head pressure to ambient rule of thumb. Hi m3ae2002, The air cooled condenser TD depends on ambient temperature. Usually, high TD is for colder ambient and low TD is for warmer ambient. In here we take : TD= 5-6°C for very hot areas like ta=50°C. TD=8-10°C for normal mbient ta=42°C. TD=12-15°C for colder areas ta=32°C.Turn on the refrigerator/freezer and wait about 15 seconds. To the conversion valve, attach an air compressor gage that is designed for Freon® systems. It lets you read both air pressure and Freon pressure. (This is like gaging tire pressure for tires.) The pressure on the Freon line should read “0.”1. The pressure-enthalpy diagram. 2 2. The basic cycle. 2 3. Intercoolers & subcoolers. 4 4. The components. 4 4.1.
