LoginIn this paper, three methods of recovering sensible heat during heating and ventilation process of heat pump have been studied experimentally.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
Experimental study of sensible heat recovery of heat pump during heating and ventilation | | English
In order to investigate the difference between mixing (MV) and displacement ventilation (DV) under different boundary conditions, a numerical simulation with a validated CFD model of several types of buildings was used.
A numerical simulation with a validated CFD model of several types of buildings was used to investigate the difference between mixing (MV) and displacement ventilation (DV) under different boundary conditions.The second part of that study deals
To study the microenvironment around human body with personalized ventilation system, a seated computational thermal manikin is used.
Using the same system for natural ventilation and smoke control is the examined possibility of that study. In that aim a prototype building is proposed : it is an eight-storey building with a solar chimney located on top of the atrium.
The aim of that study is to model and evaluate the performance of several ventilation methods in pollutant removal from indoor environments. 3 different ventilation methods are examined : a displacement ventilation and two mixing systems.
For that study, measurements were carried out in an office-type experimental room to investigate the distribution of airflow velocity and air temperature.
For the characterization of PM (particulate matter) indoor/outdoor relationships for wind induced naturally ventilated residences in taiwan region, a simple size-dependent indoor air quality model was applied in association with measured outdoo
This paper summarizes key results of ASHRAE Research project RP-1137, which sought to quantify the benefits and longevity of the recommissioning process on variable air volume (VAV) systems that incorporate direct digital control (DDC).
This paper proposes an intelligent controller for an air-handling unit to control the temperature while limiting the humidity below 70%. The proposed scheme is based on the back-propagation-through-time approach.
This study aims at developing a radiant floor cooling system using the existing Ondol (radiant floor heating system). It was found that the proposed system could provide cooling for thermal comfort with higher energy efficiency.
This paper present a survey technique for rating HVAC systems. System components are grouped into categories.
The objective of this investigation was to evaluate the field performance of room air distribution in two rooms of a high performance home (low heating and cooling load).
The laboratory air-handling unit (LAHU) system is designed to improve building energy performance and indoor air quality (IAQ) in laboratory buildings.
Local airflow gives different sensations at different locations on a human body as the thickness of natural convection is not equal over the body surface.
In a local exhaust ventilation system, the exhaust air velocity decreases very rapidly with distance from the exhaust inlet.One possible way of maintaining a high capture velocity far from the exhaust inlet is the use of vortex flow, usually calle
Relative humidity sensors are common components in building heating, ventilating and air-conditioning (HVAC) systems, and their performance can significantly impact energy use in these systems.
This paper compares two models that were developed independently for predicting the particle separation efficiency of a vane-induced uniflow cyclone. The Zhang model was based on indirect analysis.
A mathematical formulation was developed including an objective function that minimizes the cumulative exposure of occupants to pollutants under the constraints of pollutant dispersion pattern, evacuation paths, and their capacities.
This paper discusses the development of a methodology to quantify the impact of fenestration systems on human thermal comfort with a representative case study.
