  This paper is devoted to the investigation of the monotonicity of parabolic
frequency functional under conformal Ricci flow defined on a closed Riemannian
manifold of constant scalar curvature and dimension not less than 3. Parabolic
frequency functional for solutions of certain linear heat equation coupled with
conformal pressure is defined and its monotonicity under the conformal Ricci
flow is proved by applying Bakry-Emery Ricci curvature bounds. Some
consequences of the monotonicity are also presented.
