Currently, hybrid renewable energy systems with thermal energy storage have various advantages and are widely used. This paper investigated the performance of a solar‐assisted air source heat pump system with energy storage (SASHPS‐ES) in Beijing, China, and proposed an optimal operation mode based on economic evaluation. The results indicate that with the optimal heat storage ratio of 50%, the rated capacity of the air source heat pump (ASHP) of the SASHPS‐ES system can be reduced by 16.7%, decreasing its annual total cost by 26.5% under a peak‐valley electricity price policy. The price of 620¥/m2 is critical for the solar collectors. The economics of SASHPS‐ES is better than that of an air source heat pump system with energy storage (ASHPS‐ES) when the price of the selected solar collector units is less than this critical price (without subsidies from the government). In the current local market, the promotion of SASHPS‐ES systems and other solar energy applications requires government subsidies for a period of time. The results can guide the utilization and popularity of SASHPS‐ES in China.

“…To investigate various designs of a district heating pipe network, [23] constructed an objective formula to minimize the annual total energy consumption and costs so as to arrive at the optimal flow rate and supply temperature operating strategy. To achieve comprehensive use of solar energy, [24] designed and constructed an integrated solar house with solar PV system, direct-gain solar system and an advanced building envelope (e.g. Low-E glass window, flat-opening airtight door, doublelayer polyurethane insulation wall, etc.)…”

Based on analysis of construction and operation of micro integrated energy systems (MIES), this paper presents economic optimization for their configuration and sizing. After presenting typical models for MIES, a residential community MIES is developed by analyzing residential direct energy consumption within a general design procedure. Integrating with available current technologies and local resources, the systematic design considers a prime mover, fed by natural gas, with wind power, photovoltaic generation, and two storage devices serving thermal energy and power to satisfy cooling, heating and electricity demands. Control strategies for MIES also are presented in this study. Multi-objective formulas are obtained by analyzing annual cost and dumped renewable energy to achieve optimal coordination of energy supply and demand. According to historical load data and the probability distribution of distributed generation output, clustering methods based on K-means and discretization methods are employed to obtain typical scenarios representative of uncertainties. The modified non-dominated sorting genetic algorithm is applied to find the Pareto frontier of the constructed multi-objective formulas. In addition, aiming to explore the Pareto frontier, the dumped energy cost ratio is defined to check the energy balance in different MIES designs and provide decision support for the investors. Finally, simulations and comparision show the appropriateness of the developed model and the applicability of the adopted optimization algorithm.

“…Studies involving thermal parameters for solar heating have drawn much attention [16][17][18]. Zhai et al compared the thermal comfort and ventilation effect of the solar house between two different roof collectors, which indicates that a double-pass roof solar collector is superior to the single pass model from the points of view of both space heating and natural ventilation [19].…”

Passive and active solar heating systems have drawn much attention and are widely used in residence buildings in the Qinghai-Tibetan plateau due to its high radiation intensity. In fact, there is still lack of quantitative evaluation of the passive and active heating effect, especially for residential building in the Qinghai-Tibetan plateau areas. In this study, three kinds of heating strategies, including reference condition, passive solar heating condition and active solar heating condition, were tested in one demonstration residential building. The hourly air temperatures of each room under different conditions were obtained and analyzed. The results show the indoor air temperature in the living room and bedrooms (core zones) was much higher than that of other rooms under both passive and active solar heating conditions. In addition, the heating effect with different strategies for core zones of the building was evaluated by the ratio of indoor and outdoor degree hour, which indicates that solar heating could effectively reduce the traditional energy consumption and improve the indoor thermal environment. The passive solar heating could contribute 49.8% degree hours for heating under an evaluation criterion of 14 • C and the active solar heating could contribute 75% degree hours for heating under evaluation criterion of 18 • C, which indicated that solar heating could effectively reduce the traditional energy consumption and improve the indoor thermal environment in this area. These findings could provide reference for the design and application of solar heating in similar climate areas.
