ThermoAnalytics is a global pioneer in the effective simulation of human thermal comfort. Our human thermal simulation technology is an advanced plug-in for analyzing human comfort within complex environments: indoor, outdoor, and in transportation systems. This technology allows users to place virtual test dummies into these environments, and compute comfort indices. Full radiant, convective and conductive heat transfer is accounted for, including localized thermoregulatory response such as perspiration, respiration, and blood flow changes.
The virtual dummy is composed of individual body segments that allow the user to define separate layers of clothing and other local effects. The methods employed were developed by Dr. Dusan Fiala, widely considered a world leader in human thermal comfort studies. The environmental models support full weather inputs, solar models, transparent glass with greenhouse effects, and all other significant thermal variables. Multiple human dummies can be placed into realistic systems and the human metabolic loads included as part of the total system energy load, if needed.
The Berkeley Comfort Model provides localized sensation and comfort results for each body segment computed from temperatures predicted by our Human Comfort Module. The Berkeley Comfort Model was developed at the University of California-Berkeley’s Center for the Built Environment. It is an advanced design tool for assessment of localized thermal comfort designs and functions as a module in our software.
The Berkeley Comfort Model enables an engineer to study, for example, how comfortable a passenger’s feet or hands would be in an aircraft or vehicle and determine cost/benefit to a design change in ECS or HVAC.
ThermoAnalytics Human Simulation Module provides a full transient analysis of human comfort within complex asymmetrical environments. Because our software predicts a full multimode heat transfer solution, the mechanisms behind human comfort are also studied and new designs can be quickly performed for cost-benefit optimization analysis.
The Human Simulation Module accurately assigns thermal and mass resistances to each layer of clothing and connects it to the skin beneath. While clothing resistances to both heat transfer and diffusion of moisture can be defined by the user, a full library—including over 100 standard articles of clothing—is provided.
Our research engineers can deliver a fully positioned and clothed virtual dummy placed into your environment. User routines to tailor the comfort metrics or implement feedback control systems can also be delivered with full engineering reports and analyses.
