Summary

Mathematical algorithms have been developed as the foundation of an environmental assessment model for mobile shelters. The assessment model can be used for sizing the heating and cooling equipment and for evaluating the transient thermal responses of shelters under specified initial heat up and cool down conditions. The new shelter environmental assessment model has the ability to predict inside temperature as a function of variations in environmental conditions, HVAC equipment performance, and inside load conditions. The algorithms use a multi-mode lumped-capacity model for the shelter walls, the equipment and the air inside the shelter, since each of these elements has an energy storage capacity. Therefore, radiation shield temperatures are computed from iterative, steady-state energy balances for each time step. The unknown temperatures for the elements with heat capacity are calculated at each point in time using a "step-by-step" solution combined with the radiation shield temperatures. The model is designed to accommodate the energy gains from equipment and personnel, and operational features of HVAC equipment, with weather data for a specific location or from standard outdoor environmental conditions.
