    • Apparatus, systems, methods, and related computer program products for generating and implementing thermodynamic models of a structure. Thermostats disclosed herein are operable to control an HVAC system. In controlling the HVAC system, a need to determine an expected indoor temperature profile for a particular schedule of setpoint temperatures may arise. To make such a determination, a thermodynamic model of the structure may be used. The thermodynamic model may be generated by fitting weighting factors of a set of basis functions to a variety of historical data including time information, temperature information, and HVAC actuation state information. The set of basis functions characterize an indoor temperature trajectory of the structure in response to a change in HVAC actuation state, and include an inertial carryover component that characterizes a carryover of a rate of indoor temperature change that was occurring immediately prior to the change in actuation state.
    • 用于生成和实施结构的热力学模型的装置,系统,方法和相关的计算机程序产品。 本文公开的温控器可操作以控制HVAC系统。 在控制HVAC系统时,可能需要确定特定设定值温度的预期室内温度曲线。 为了做出这样的决定,可以使用该结构的热力学模型。 可以通过将一组基础函数的加权因子拟合到包括时间信息,温度信息和HVAC致动状态信息的各种历史数据来生成热力学模型。 一组基础功能表征了响应于HVAC致动状态变化的结构的室内温度轨迹,并且包括表征在致动变化之前发生的室内温度变化率的惯性携带部件 州。
