In this paper, a purposely designed code for the performance analysis of the Water Loop Heat Pump (WLHP) systems is presented. Hourly, daily and seasonal energy system consumptions, operating economic costs and environmental impact assessments are dealt with. For the scope of comparison, the...

Conducting energy-efficient designs on building window can be a solution to relieving the pressure caused by growing building energy consumption. In this paper, a series of simulation studies were carried out to evaluate the performance of several popular energy-efficient window designs in...

The thermal performance of building envelopes is the determinant factor of building energy consumption, and especially envelope retrofitting is an effective way of reducing energy consumptions in existing building. For different climates, there may exist different optimal retrofitting schemes....

Due to its high thermal performance, ground source heat pump systems (GSHPs) have been introduced as an alternative to reduce energy consumption of heating and cooling systems. The thermal performance of GSHPs strongly depends on ground temperature and energy demand for heating and cooling...

If buildings can change “clothes” according to seasons like human being, the energy consumption for their space heating or cooling will be saved greatly. For this purpose, the thermophysical properties of building external wall should be self-adjusted according to outdoor temperature. In...

Today, green roofs are a building system which provides interesting benefits over traditional roof solutions. The most important advantages are the reduction of surface runoff in cities, improvement of the urban climate, biodiversity support, improvement of the durability of roofing materials,...

Thermal properties of materials used in building envelopes must be analysed in order to evaluate the thermal response of the constructive system. This thermal characterisation is a key point during the design phase of a building. However, thermal characterisation of constructive systems at...

The present paper is aimed at putting forward a two-dimensional model for thermoelectric cells. The energy conservation equation was formulated in order to account for the Fourier (heat) conduction, the Thomson (thermoelectric) effect, and the Joule heating on the temperature distribution. The...

This study presents a detailed kinetic mechanism conducted by CHEMKIN for the homogeneous decomposition of SO3–H2O vapor in the sulfur–iodine cycle. The kinetic mechanism involving 27 reactions and 11 species was validated by experimental results. The effects of temperature, SO3/H2O ratio,...

Underwater compressed air energy storage (UWCAES) is founded on mature concepts, many of them sourced from underground compressed air energy storage technology. A fundamental difference between the two systems is the way in which air is stored. UWCAES utilizes distensible boundary, submerged air...
