Title:
HEAT SOURCE MACHINE GROUP OPERATION CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2015004500
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat source machine group operation control technology suitable for a case where a cooling load and a heating load exist simultaneously, in a datacenter or the like.SOLUTION: When a heating load in an office room 4 is one unit, units 2A, 2B, 2D, 2E perform cooling operation for supply to a server room 3, and a unit 2C performs heating operation for supply to the office room 4. Consequently, exhaust from an ambient air heat exchange part 2c of the unit 2C becomes lower temperature than ambient air, to discharge it to the outside of a machine. Low-temperature exhaust is short-circuited to be introduced into the ambient air heat exchange parts 2c of the units 2D, 2E, and then subjected to cold recovery by coolant flowing in a heat exchanger 2b. Thus, system efficiency can be improved.
