WebAs seen in Table 1, N-butane has a higher COP than isobutane, if no losses are present in the compressor. However N-butane is more sensitive to clearance volume, suction side … WebThe Global Warming Potential (GWP) was introduced. Carbon dioxide potential is taken as unity, i.e., GWP-CO 2 ≡ 1. The GWP compares the amount of heat that affects global warming that is absorbed by a certain mass of refrigerant (usually 1 kg) with the amount of heat absorbed by the same mass of CO 2 .
Webn-Butane is one of the structural isomers of Butane, an organic compound with the formula C4H10 that is an alkane with four carbon atoms.
