AIR CONDITIONER AND ITS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an air conditioner with improved energy-saving properties and its control method that can reduce operation power, while securing sufficient cooling capacity, and hence can improve operation efficiency drastically. SOLUTION: The operation of a refrigeration cycle and that of a cooling water circulation cycle are controlled to a state for obtaining the maximum cooling capacity, when an indoor temperature is equal to or more than a specific value. The operation of the refrigeration cycle and that of the cooling water circulation cycle are controlled to a state for obtaining a required cooling capacity with a very small operation power, when the indoor temperature is less than the specific value.
