The paper outlines the design concept of the condensing boiler and its application in domestic heating systems and discusses the energy savings, investment opportunities and other benefits that can be realised. It also examines the potential market for condensing boilers and some initiatives that are aimed at promoting them in regard to both the end user and the heating designer and installer.
Several case studies from the Iowa State University Extension show that carbon monoxide hazards exist even with new gas appliances. Proper installation and analysis are key to avoiding or solving these problems.
In this paper, theoretic review of a heat pump use and operation is given. Further, the possibilities of a heat pump use in heating and air-conditioning is analysed, especially considering the tourist and catering facilities. The economic and environment protecting effects of a heat pump use as an energy source (conditionally speaking) in the air-conditioning process is pointed out. It is shown that these effect make a heat pump use justifiably attractive.
The belief that the addition of mass to a building will reduce its energy requirement is now widespread. Fiona Cousins and Bob long investigate how this principle, often observed in the coolness of cathedrals, castles and caves during summer, can be applied to modern buildings
The primary objective of this study was to evaluate the effectiveness of different commercially available portable indoor air cleaning technologies in removing dust particulates from the indoor air. Suspended respirable particles are of great concern and often identified as important source of indoor air quality problems. The concentrations of particulate and gaseous pollutants encountered in the indoor environment frequently exceed those found outdoors by factor ranging from 2 to 20.
