Heat Store

At Stuttgart University, a solar heating system for an office building with laboratories and lecture rooms was installed in 1985. It consists of 211 m2 of unglazed solar collectors, a 1050 m3 water-flooded pebble bed heat store, and a heat pump. Heat can be supplied to the store from the solar collectors or from a power station (as waste heat). The whole system has worked successfully for five years under varied strategies. In the first two heating periods, the heating strategy was aimed to collect as much solar energy as possible. Thus, about 60 percent of the heat demand could be covered by solar energy; but the yearly heat pump coefficient of performance (COP) was only around 2.76. With an improved heat pump, a monthly COP of 3.6 was obtained. Heat losses from the storage amounted to about 20 percent.

And Performance

A detachable, automotive solar system for water and passenger compartment heating is developed. The study shows that an adjustable 1 m2 solar collector is sufficient to satisfy the needs of a small group during a short camping trip in Saudi Arabia desert. Also it is found that an adequate water temperature in the storage tank, due to ambient solar heating, is maintained in all cold months, except December when it is insufficient. Among the advantages of the system is its entire operation on renewable solar energy and its ability to heat the car compartment whenever the heated water reaches the required temperature and solar energy is still available.

The biogas amounts with stable flowing rate require heating in cold weather. This study focuses on using solar energy for heating biogas digester. In this research we used energy plus building energy simulation software and real weather data for simulation the heating of biogas digester with 8760 hours simulation .The research was carried out in two parts: The first one is one biogas digester above ground without heating. The Second part of this study is a simulation of one biogas digester with solar heating by using a new design based on double plastic cover. It has shown that the use of solar energy can achieve the optimum temperature for biogas production process almost the year time. Using double plastic cover is the most suitable method with economic form for heating biogas digester above ground.

Solar energy, as an inexhaustible renewable energy, can be used to produce heat and electricity. It is of great importance to examine the strategy for investment on solar energy technology. In response to varying electricity price in the electricity market, the battery energy storage system (BESS) can be used to get price arbitrage. This paper proposes an optimal configuration model for a photovoltaic (PV) system, solar heating system, and BESS in order to obtain maximum profit for investors. The investment potential of these systems is compared and analyzed based on return on investment (ROI) index which is defined to evaluate economic profitability. A bi-level programming is adopted to optimize the operation strategy of batteries (inner layer), the size of PV system and solar heating system, and the size of batteries (outer layer) including their maximum discharge/charge power and capacity. Sequential quadratic programming (SQP) method and particle swarm optimization (PSO) are used as optimization methods. In the case study, five investment strategies are investigated in order to decide how to invest in PV modules, batteries, and solar thermal collectors. The results show that the BESS may be a preferable choice for the investors if the investment cost of BESS goes down a lot in the future. Investing in solar energy for both heat and power may be not reasonable because the ROI of this strategy is always higher than either investing in heat or in power. The optimal strategy may be changed with the fluctuation of heat and electricity prices.

Passive Solar

A notion ‘passive solar building design’ has been arisen so far. In fact, it means heat flows management using architectural shaping. Architectural shaping is based on logic of heat flows generation and movement. Nowadays, an architectural form has no direct relation to a structure as close as it used to be before. Ways and means of energy supply step forward and become a significant forming factor.It has been analyzed herein how solar energy as an environmental factor affects architectural shaping and design.

It is a collector-tank-double pump cycle of floor heating system, combining solar heating system with solar hot water system. Collectors are concentrating vacuum tube collectors, which can efficiently use solar energy. Combining solar collector with the building integration, we can use solar energy resources, and it can play shading effect.
