Abstract
A chiller system is provided. The chiller system may include a plurality of chillers, each of which may include a compressor, a condenser, and an evaporator, and a controller that controls the plurality of chillers. The controller may determine an expected load and a chiller to be operated of the plurality of chillers on the basis of the determined expected load to operate the determined chiller.
Claims28
A chiller system, comprising:
- a plurality of chillers, each of which comprises a compressor, a condenser, and an evaporator;
- and
- a controller that controls the plurality of chillers, wherein the controller determines an expected load and a chiller of the plurality of chillers to be operated on the basis of the determined expected load, and operates the determined chiller.
A chiller system, comprising:
- a first chiller comprising a first compressor;
- a second chiller comprising a second compressor having a capacity greater than a capacity of the first compressor;
- and
- a controller to control the first and second chillers, wherein, when it is determined that an operation starting command is input, the controller determines a chiller to be operated of the first and second chillers and operates the determined chiller.
1 more element
A chiller system, comprising:
- a first chiller comprising a first compressor;
- a second chiller comprising a second compressor having a capacity greater than a capacity of the first compressor;
- and
- a controller to control the first and second chillers, wherein, when it is determined that an operation method change is needed while at least one of the first chiller or the second chiller operates, the controller stops the operating chiller and operates the other chiller, or stops one chiller module while all of the chillers operate, or additionally operates the other chiller while the one chiller operates.
1 more element
A chiller system, comprising:
- a plurality of chillers, each of which comprises a compressor, a condenser, and an evaporator;
- and
- a controller that controls the plurality of chillers, wherein the controller determines an expected load and a chiller or chillers of the plurality of chillers to be operated on the basis of the determined expected load, and operates the determined chiller or chillers, wherein the controller determines the expected load on the basis of an expected load factor and an expected head factor of an operating chiller, wherein the expected load factor is determined on the basis of a temperature of cold water introduced into the evaporator of the operating chiller and a target cold water outflow temperature, and wherein the expected head factor is determined on the basis of a temperature of cooling water introduced into the condenser of the operating chiller and the target cold water outflow temperature.
