7.1.5 <strong>Compressor</strong> operating fields COMPRESSORS HANDBOOK Chapter RUNNING DATA AND COMPRESSOR CHECKING PROCEDURES Within the minimum and maximum values typical for each model. In the diagrams represented on the following pages, indicated are the limits of evaporating, condensing, ambient and return gas temperatures. The compressor can operate within the limits of evaporating and condensing temperatures defined by the outlined area bordered by a continuous line, at the indicated conditions of ambient and return gas temperature. Outside these operating fields, the system operates at high pressures and high temperatures, and cause early defects in the compressor. The compressor defects caused by applications operating outside the prescribed fields will not be considered under warranty. 7.1.5.1 R22 <strong>Compressor</strong>s operating field The production of R22 compressors was required for the replacement of R12 - R502 refrigerants and the choice has been obliged by the non availability at that moment of other suitable alternative gases. For low and medium temperature R22 cabinets, compressors must be selected according to the limits associated with this type of gas, that was developed for high evaporating temperatures, thus characterized by restrictive limits. 7.1.5.2 R404A - R507 - R600a - R134a - R22 – R290 compressors operating field The working fields represented in this section are related to all model and series of compressors that take the indicated refrigerant. 1 – LBP: R134a – R600a 2 – LBP: R404A – R507 – R290 3 – MBP: R404A – R507 – R290 4 – HBP: R134a – R600a – R 22 5 – LBP: R 22 6 – AC Doc.
