How to calculate time required for cooling

WebThe heat, Q, required to change the phase of a sample of mass m is Q = m L f (for melting/freezing), Q = m L v (for vaporization/condensation), where L f is the latent heat of fusion, and L v is the latent heat of vaporization. The latent heat of fusion is the amount of heat needed to cause a phase change between solid and liquid. Web19 okt. 2024 · The following formula is used to calculate a cooling capacity of a chiller. Q = m' * Cp * ΔT Q = m′ ∗ Cp ∗ ΔT Where Q is the cooling capacity (kW) m’ is the mass flow rate of the chilled water (kg/s) Cp is the specific heat of the water (kJ/kg/K) ΔT is the change in temperature of the water at the inlet and outlet (K or C)
