Calculation of cooling area of sampling cooler

铂莱娱乐场1: If the sample flow rate, cooling water temperature, and initial conditions of the sample are known, then the cooling surface required for the sampling cooler

The product can be obtained from equation (A1):

A=f • 1.0029/3600 Δ Tm • U (A1)

Equation - A - required cooling area, m2;

F - Sample flow rate, L/h;

铂莱娱乐场Δ Tm - average temperature difference, ℃;

铂莱娱乐场U - Overall heat exchange coefficient (U=200 for double-layer spiral tubes and immersion coolers).

铂莱娱乐场When the sample is superheated steam, for every 100 ℃ superheat, the cooling area calculated by equation (A1) should be based on

On the basis of this, it will increase by 12.6%.

铂莱娱乐场2: The average temperature difference can be obtained from equation (A2):

Δ Tm=[(t1-T2) - (t2-T1)]/[L (t1-T2)/(t2-T1)] (A2)

Equation-

铂莱娱乐场Δ Tm - average temperature difference, ℃;

铂莱娱乐场T1- cooler sample temperature, ℃;

T2- cooler sample temperature, ℃;

T1- cooler - cooling water temperature, ℃;

铂莱娱乐场T2- Cooling water temperature at the outlet of the cooler, ℃.

3: The spiral tube of the cooler can be composed of a continuous coil with the required cooling area, or it can be arranged inside and outside of two sets of spiral tubes.
