The present disclosure relates to a computer based system for collecting, analyzing and presenting temperature information from sensors associated with an HVAC system. The system makes use of a processor for communicating with the plurality of sensors and obtaining temperature data reported by each of the sensors. A graphical user interface (GUI) module is provided which is embodied in a non-transient medium and configured to run on a computing device having a display screen. The user GUI module uses the temperature data, in real time, to generate a graph on the display screen. The graph includes a plurality of components each having different indicia to indicate groups of sensors that are below a predetermined lower temperature limit, above a predetermined upper temperature limit, and within a predetermined temperature range. Standard deviation information may be supplied with the graph which relates to the maximum standard deviation of those groups of sensors that are reporting temperatures above and below the predetermined temperature range.

System and method for inferring or prompting HVAC actions based on large data standard deviation based metric

A method is disclosed for analyzing performance of a chilled water (CW) system having a plurality of CW components. The method may consider a collection of at least one of allowable operating points, allowable operating ranges or allowable operating conditions, for each one of the CW components. A user set or system measured ambient wet bulb (WB) temperature may be considered for an environment in which at least a subplurality of the CW components are located. Equivalent loop conditions may be calculated for each of the CW components covering a load being thermally managed by the CW system. For each one of the calculated equivalent loop conditions, a processor may generate information for balancing the CW components to meet load requirements, and then analyze and select a balance condition that yields the user preferable optimization.

System and method for energy analysis and predictive modeling of components of a cooling system

A cooling system for an equipment closet in a building has a direct expansion cooling circuit. The cooling system has two basic modes of operation. A first mode where the direct expansion cooling circuit is off and transfer air from an area of the building outside the equipment closet is used to cool the interior of the equipment closet without any cooling provided by the direct expansion cooling circuit and a second mode where the direct expansion cooling circuit is on and provides direct expansion cooling that is used to cool the interior of the equipment closet.

The present disclosure relates to a processor based system for using temperature information being reported by a plurality of sensors present within a predetermined environment and controlling how various ones of the sensors are grouped together into a plurality of groups for monitoring purposes. The system includes a software subsystem that generates an association matrix screen on a display system associated with a computer system being used by a user with receives the temperature information. The association matrix screen enables a user to associate or disassociate specific sensors with selected groups of sensors using selection commands, as well as to provide temperature related information concerning all of the sensors being monitored by the system. Each of the sensors is not limited to being assigned to only a single group of sensors but may instead be assigned to two or more different groups of sensors for purposes of monitoring and/or control.
