PROCESS COOLING AND AIR CONDITIONING PACKAGE APPARATUS, AND ITS HEAT SOURCE SUPPLY METHOD

摘要

PROBLEM TO BE SOLVED: To provide a process cooling and air conditioning package apparatus which has a multi-function freezing cycle composed of a cooling function comprising an air conditioning cold heat source and 2 to 3 systems of cold heat sources for process cooling of refrigeration and freezing and a heating function, and which employs a natural system primary refrigerant without the feat of environment destruction and a brine system secondary refrigerant, and further to provide a heat source supply method ensuring safe operation of the systems. SOLUTION: A package apparatus for process cooling and air conditioning comprises a multi-function freezing cycle 30 composed of two stage compression one stage expansion type freezing cycle, an air conditioning cold/warm heat circuit 27, and a process cold heat circuit 26.
