In the coolant application system, the system is usually determined in the design stage. In the later stage, It is necessary to replace the coolant with different physical properties of the system. there will be some mismatches, and the final result is the reduction of energy efficiency.from the perspective of heat transfer and fluid, It is found that the specific heat and density have a great impact on the system.
The specific heat usually refers to the heat required for 1kg homogeneous material to increase by 1K without phase change and chemical change. Generally, this value will decrease with the decrease of temperature. this parameter is usually used in design calculation, and the density of coolant is calculated jointly with this parameter. it is one-sided to comment on the quality of the coolant by talking about a specific heat.
The specific heat can be combined with the density to calculate the circulating volume of the system. From the perspective of fluid, the circulating volume is directly related to the circulating energy consumption of the coolant. The pump power can be determined by combining the viscosity and flow rate of the coolant. Another is to determine the material and pipe diameter of the circulating system pipeline and its impact on the initial investment of the system. From the perspective of heat transfer, under the unit circulating volume, the larger the volume specific heat is, the greater the heat exchange is, which is more beneficial to the circulation of the system. The efficiency of the heat exchanger is different according to the parameters of the heat exchanger，ε=（t2-t1）/（T1-t1），或ε=（T2-T1）/（T1-t1）.With large volume specific heat, the available temperature difference of T2-T1 will increase, and the heat exchange efficiency ε will improve.
Obtaining a higher volume specific heat can improve the fluid heat transfer efficiency, but it also needs to be combined with the thermal conductivity, kinematic viscosity and Pr number of the coolant. The comprehensive efficiency of these parameters is to finally determine which coolant is more suitable.
