Core Concepts
The author introduces innovative thermal comfort control techniques focusing on personalized comfort and energy efficiency through the "Humans-in-the-Building" approach.
Abstract
The content discusses redefining indoor temperature design by prioritizing personalized comfort over traditional temperature-centric approaches. It emphasizes the importance of considering individual preferences to minimize discomfort and reduce building energy consumption. The paper proposes a novel method to determine optimal indoor temperature ranges based on user diversity, aiming to enhance overall comfort and productivity while reducing energy costs. By integrating user perceptions into energy management systems, the approach seeks to balance energy consumption reduction with enhanced user comfort. The simulations conducted using Matlab validate the efficacy of the proposed thermal comfort control approach.
Stats
"Given the significant rise in energy costs within the industry and service sectors, the consideration of both reducing energy consumption and individual comfort emerges as a goal with mutual benefits."
"For instance, consider a room with 4 users, assuming the users’ ideal room temperature set is T ∗ = [17, 18, 19.5, 20], and the comfort tolerance set is ∆i = [2, 2, 3, 1.5]."
"With the variation of indoor temperature, the sum of discomfort signals for all users can be obtained."
"When users have a thermal comfort tolerance of 3, their acceptable temperature range expands, leading to a broader optimal indoor temperature range [17, 20] where the sum of discomfort signals is zero."
"In cases where ∆i = ∆ = 0 and ∆i = ∆ = 1, h ≠ g when h = 0."
