The refrigerants which are first cooled by _________ refrigerants and then used for cooling purposes are known as ___________ refrigerants. Correct Answer primary, secondary

Primary refrigerants are the one which takes a direct part in the refrigeration system. By absorbing the latent heat of vaporization effective refrigeration in produced. Whereas, refrigerants used for cooling purpose but firstly cooled by primary refrigerants are secondary refrigerants.
