Effects of alternative control strategies of water-evaporative cooling systems on energy efficiency and plume control: A case study
TL;DR: In this article, the authors evaluated the plume potential and plume control of a huge chiller plant using water-evaporative cooling towers for heat rejection for a super high-rising commercial office building in a subtropical region of Hong Kong.
Journal ArticleDOI
An improvement to frequency-domain regression method for calculating conduction transfer functions of building walls
TL;DR: In this paper, an improvement for the frequency-domain regression (FDR) method to calculate CTF (conduction transfer function) coefficients of multilayer constructions is proposed, which provides complete CTF coefficients with a unique set of d values.
Journal ArticleDOI
Short time step heat flow calculation of building constructions based on frequency-domain regression method
TL;DR: In this paper, the authors investigated the performance of CTF coefficients at various short time steps based on FDR method, and showed that the calculated heat flows using these coefficients are of high accuracy.
Journal ArticleDOI

Xinhua Xu,Shengwei Wang +1 more
TL;DR: In this paper, a simple time domain calculation method to derive thermal response factors and conduction transfer conduction (CTF) coefficients of finite differential models for estimating transient heat transfer through building structures is presented.
Journal ArticleDOI
Evaluation of alternative arrangements of a heat pump system for plume abatement in a large-scale chiller plant in a subtropical region
TL;DR: In this paper, the authors evaluated the impacts of three arrangements of the heat pump system on the plume control performance and the energy performance in a large-scale chiller plant in Hong Kong.
