Abstract
Methods and systems for systems and methods for optimizing usage of a free cooling subsystem are provided. The method includes collecting micro-climate data from one or more sensors surrounding a facility. The method also includes analyzing the micro-climate data and making a determination to operate a free cooling subsystem or a paid cooling subsystem based on the analysis of the micro-climate data.
Claims17
A method comprising:
- collecting micro-climate data from one or more sensors surrounding a facility;
- analyzing the micro-climate data;
- and
- wherein the analyzing the micro-climate data comprises comparing a power required to operate a free cooling subsystem with a power required to operate a paid cooling subsystem;
- making a determination to operate the free cooling subsystem or the paid cooling subsystem based on the analysis of the micro-climate data,
- wherein, in determining when to switch from the free cooling subsystem to the paid cooling subsystem, the analyzing of the micro-climate data further comprises:
- determining a predicted time to switch off the free cooling subsystem;
- and
- comparing the predicted time to switch off the free cooling subsystem with a reaction time to activate the paid cooling subsystem,
- wherein the paid cooling subsystem is activated based on a time difference between the predicted time to switch off the free cooling subsystem and the reaction time to activate the paid cooling subsystem, and
- wherein the predicted time to switch off the free cooling subsystem is based on a change in temperature over a change in time.

A cooling system comprising:
- one or more paid cooling subsystems and one or more free cooling subsystems;
- at least one sensor which monitors a micro-climate in a vicinity of a cooling tower and is configured to collect the micro-climate data;
- and
- at least one component operable to analyze the micro-climate data and determine that free cooling opportunities are available;
- wherein the analyzing the micro-climate data comprises comparing a power required to operate the one or more paid cooling subsystems and a power required to operate the one or more free cooling subsystems,
- wherein, in determining when to switch from the free cooling subsystem to the paid cooling subsystem, the analyzing of the micro-climate data further comprises:
- determining a predicted time to switch off the free cooling subsystem;
- and
- comparing the predicted time to switch off the free cooling subsystem with a reaction time to activate the paid cooling subsystem,
- wherein the paid cooling subsystem is activated based on a time difference between the predicted time to switch off the free cooling subsystem and the reaction time to activate the paid cooling subsystem, and
- wherein the predicted time to switch off the free cooling subsystem is based on a change in temperature over a change in time.
8 more elements
A computer system for optimizing usage of a free cooling subsystem, the system comprising:
- a CPU, a computer readable memory and a computer readable storage media;
- first program instructions to collect micro-climate data from one or more sensors;
- second program instructions to analyze the micro-climate data;
- wherein the analyzing the micro-climate data comprises comparing a power required to operate a free cooling subsystem with a power required to operate a paid cooling subsystem;
- third program instructions to operate the free cooling subsystem based on the analysis of the micro-climate data,
- wherein the first, second, and third program instructions are stored on the computer readable storage media for execution by the CPU via the computer readable memory,
- wherein, in determining when to switch from the free cooling subsystem to the paid cooling subsystem, the analyzing of the micro-climate data further comprises:
- determining a predicted time to switch off the free cooling subsystem;
- and
- comparing the predicted time to switch off the free cooling subsystem with a reaction time to activate the paid cooling subsystem,
- wherein the paid cooling subsystem is activated based on a time difference between the predicted time to switch off the free cooling subsystem and the reaction time to activate the paid cooling subsystem, and
- wherein the predicted time to switch off the free cooling subsystem is based on a change in temperature over a change in time.
