Abstract:
This study presents an innovative concept of a compact integrated solar-thermoelectric module that can form part of the building envelope. The heating/cooling modes use the photovoltaic electrical current to power the heat pump. The experimental analysis was carried out and the results of coefficient of performance were in the range 0.5–1 and 2.6–5 for cooling and heating functions, respectively. The study demonstrates that thermoelectric cooler can effectively be used for heating, ventilation, and air conditioning applications by integrating with solar panels especially in cooling applications. The system is environmentally friendly and can contribute in the implementation of zero energy buildings concept. Practical application: In order to help address the challenge of climate change and associated environmental effects, there is continuous demand for new technologies and applications that can be readily integrated into day-to-day life as a means of reducing anthropogenic impact. Heating, ventilation, and air conditioning, as one of the largest energy consumers in buildings, is the focus of many researchers seeking to reduce building energy use and environmental impact. This article proposes using facades and windows that have an integrated modules of solar photovoltaic cells and thermoelectric devices that are able to work together to achieve heating and cooling effects as required by the building without requiring any external operational power.

Abstract:
This study takes the ventilation into consideration, making the active building envelope (ABE) system more close to the realistic application conditions. The ABE system is comprised of a photovoltaic unit (PV unit) and a thermoelectric heat pump unit (TE unit). The PV unit consists of photovoltaic cells, which convert solar radiation energy into electrical energy. The TE unit consists of thermoelectric heaters/coolers (referred to here onwards as TE coolers), which convert electrical energy into thermal energy, or the reverse. The PV and the TE units are integrated within the overall ABE enclosure. The new mechanism of a hybrid system was proposed. A ducted wind turine will be integrated with the ABE system becoming dual core. Then the analytic model of original ABE system has to be revised and analytic solution will be resulted and verified by the numerical solution of CFD. The ducted wind mill will provide air conditioning and power the ABE system, to higher the thermal efficiency of the heat sinks of TE system. Numerical and experimental works will be investigated. a building installed the ABE system wind, solar driven, bypass the windmill flow as a air flow, ambient temperature, To is equal to 35 oC and indoor temperature, Ti is 28 oC. Numerical results show the Ti will decrease 2 oC when the ABE operating with heat sinks, without fan. As fan is opened, strong convective heat transfer, Ti will decrease approximately 4 to 5 oC. We hope findings of this study can make the dream of healthy living comfortable room come true.

Abstract:
A thermoelectric module is a device that converts electrical energy into thermal energy through a mechanism known as the Peltier effect. A Peltier device has hot and cold sides/substrates, and heat can be pumped from the cold side to the hot side under a given voltage. By applying it in buildings and attaching it to building envelope components, such as walls, as a heating and cooling device, the heating and cooling requirements can be met by reversing the voltage applied on these two sides/substrates. In this paper, we describe a novel, panelized, ground source, radiant system design for space heating and cooling in buildings by utilizing the Peltier effect. The system is equipped with water pipes that are attached to one side of the panel and connected with a ground loop to exchange heat between the cold/hot sides of the thermoelectric module and the underground region. The ground loop is inserted in boreholes, similar to those used for a vertical closed-loop Ground Source Heat Pump (GSHP) system, which could be more than a hundred meters deep. Experiments were conducted to evaluate the feasibility of the developed panel system applied in buildings. The results show that: (1) the average cooling Coefficients Of Performance (COP) of the system are low (0.6 or less) even though the ground is used as a heat sink, and thus additional studies are needed to improve it in the future, such as to arrange the thermoelectric modules in cascade and/or develop a new thermoelectric material that has a large Seebeck coefficient; and (2) the developed system using the underground region as the heat source has the potential of meeting heating loads of a building while maintaining at a higher system coefficient of performance (up to ~3.0) for space heating, compared to conventional heating devices, such as furnaces or boilers, especially in a region with mild winters and relatively warm ground.

Abstract:
Heating, ventilation, and air conditioning (HVAC) accounts for 40% to 60% of residential and commercial building energy consumption, making this a critical component of energy usage in the face of rising energy prices. Building-integrated thermoelectrics (BITE) may provide a step towards adaptive homes and buildings that offer significantly improved efficiency and comfort. Integrating thermoelectrics into thermal mass and resistance (insulation) wall systems presents a fundamental shift from optimizing heating and cooling source efficiencies and minimizing building-envelope energy losses to a new regime where an active envelope is optimized to most efficiently eliminate those losses. This approach not only offers improved energy efficiency, but improves the uniformity and consistency of temperature, eliminates the need for all other heating and air conditioning equipment including thermal energy transport, and provides the platform for adaptive zone heating and cooling which can provide additional efficiency gains. Because of the solid-state nature of thermoelectrics, such a system would be reliable, low maintenance, silent, and clean. This paper examines various wall configurations and sizing for thermal mass, resistance, and thermoelectric components. A dynamic simulation is used to demonstrate how proper system design of thermal resistance and capacitance elements with existing thermoelectric materials may improve the typically low coefficient of performance of thermoelectric devices, making it competitive with traditional building systems. The results for different wall configurations are shown as a basis for future configuration design and optimization.

Abstract:
Active Building Envelope (ABE) systems represent a new thermal control technology that actively uses solar energy to compensate for passive heat losses or gains in building envelopes or other enclosures. This paper introduces the first steps in exposing the community to this new technology, and explores an optimization based design strategy for its feasible application. The overall system is discussed, while this paper also gives particular focus to the design of a key constituent component. Namely, the collection of thermoelectric heat pumps; or, the TE unit. The latter becomes an integral part of the generic enclosure, and is a collection of thermoelectric coolers, or heaters. As a critical component of the optimization based design strategy, select computationally inexpensive approximate analytical models of generic TE coolers/heaters (TE Cooler) are developed. The optimization technique is implemented to evaluate different design configurations of the TE unit. The preliminary results indicate that the total input power required to operate the TE unit decreases as the distribution density of the TE coolers increases. In addition, the thermal resistance of the heat sink (attached to the TE cooler) plays a key role in determining the number of TE coolers required. These preliminary findings may have practical implications regarding the implementation of the ABE system.

Abstract:
Abstract Buildings are known as one of the foremost energy consumer sectors in the world with a share of nearly 40% and hence the design and development of clean and energy efficient building energy systems is an important step towards a sustainable future. Cooling and air conditioning systems, as an essential component for occupants’ comfort, are among the largest energy end-users in buildings. Additionally, most air conditioning systems rely on using refrigerants that are harmful for the environment with considerable potential for ozone depletion and global warming. Solid-state cooling technologies that do not require refrigerant are therefore of interest to eliminate these environmental concerns. Thermoelectric (TE) modules, as a solid-state cooling technology, when supplied by DC electricity, produce a temperature gradient through the Peltier effect that can be used for cooling purposes. Due to the attractive characteristics that TE technology offers, mainly high controllability, lack of refrigerant and large moving parts, quiet operation, promising efficiency and requiring minimum maintenance required, TE-based systems are becoming an emerging technology for building cooling applications. TE-based cooling technologies have been developed and tested through integrated and non-integrated systems in the building envelope. In the present paper, the design of a TE-based radiant cooling ceiling panel is investigated through numerical modeling and parametric study. The system can be incorporated in the ceiling and will maintain a reduced ceiling temperature to provide cooling through radiation and convection for the occupants. COMSOL Multiphysics is used for modeling and simulation purposes and the performance of the system under various configurations is assessed. The effect of number and placement of TE modules for a given size of ceiling panel are investigated using several simulations in COMSOL to achieve a desired and uniform surface temperature in the minimum amount of time. The impact of incorporating various amounts of phase change material (PCM) in the ceiling panel is also assessed. PCM allows the ceiling panel to maintain the desired temperature for an extended amount of time, but it also increases the time that it takes for the panel to reach the desired temperature. Transient thermal simulations are performed for both start up and shut down scenarios and the amount of time that it takes for the ceiling temperature to cool down to the desired level (on-mode) or heat up (off-mode) to the temperature at which it has to turn back on again are calculated for various system configurations. The results from this study can be used for optimal design of TE-based radiant cooling ceiling panels to achieve high energy efficiency and low operating cost while maintaining occupants’ comfort in the buildings.

Abstract:
Active Building Envelope (ABE) systems are a new enclosure technology which integrate photovoltaic (PV) and thermoelectric (TE) technologies. In ABE systems, a PV system is used to transfer solar energy directly into electrical energy, which is used to power a TE heat-pump system for space cooling or heating. In this study, we have built a computational model to predict the indoor temperature of an outdoor testing room and its integrated ABE system. The computational model uses the finite differential method, and includes the computation of solar radiation, heat transfer through the testing room surfaces and the ABE-window, and a model for the indoor air. We have verified the model’s accuracy by comparing the simulation results of this model with actual temperature data. We have found that there was good correlation between the model’s prediction for indoor temperature, and the actual temperature measurements for our testing room. The model will be used in further studies to assess the effectiveness of the ABE system.
