I have to use this specific heat value to calculate the heat load for designing a machine as refrigerator.
Could you please help me to find accurate value.

ps. This normal saline is used for medication.

It is within a few percent of pure water specific heat, won't it be enough?

Thank you for your attention,Borek.
You mean that I can use the specific heat of Normal Saline as equal as the specific heat of pure water.
and I've seen some website told like this,too. I found some results told that the properties is as same as pure water such as boiling point,melting point,..but
It's necessary to have a evidence to support this issue for my graduating bachelor degree's project.
please,help.

This link provides some data for the properties of saline solutions:

Scroll down for specific heat.

Adding salt to water reduces the specific heat. For the concentration that you have, Borek is right, the spec. ht. for pure water is a conservative number.
