WebOct 23, 2014 · Q = m x C x ΔT. Q = Heat Load (BTU/hr) m = Mass of fluid being cooled. C = Specific heat of fluid (BTU/lb-°F) ΔT = Change in fluid temperature. Since we know that … WebA chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. A vapor-compression chiller uses a refrigerant internally … WebThe plant parameters for an air-cooled chiller must be specified as follows. Chiller performance maps: Qcmpr (kBtu/h) = fc(ρs, Ps, Pd, Sc) and Ecmpr (kW) = fp(ρs, Ps, Pd, Sc) where ρs = suction density, Ps, Pd = suction and discharge pressures, and Sc = compressor shaft speed.
