Saving Effect

Abstract This paper analyzes the energy saving effect and optimal operation of the integrated park type energy system. The park type integrated energy system includes photovoltaic power generation system, ground source heat pump system, solar air conditioning system, regenerative electric boiler system and solar hot water system and so on. The energy saving benefit calculation model of each subsystem is established, and according to the operation history data of each subsystem, the calculation results of each subsystem are analyzed. It shows that: The energy saving income of photovoltaic power generation system is 734,200 yuan/year. The main revenue comes from the second and third quarters, during which it should pay attention to the maintenance of photovoltaic modules to ensure the maximum energy saving benefit. The energy saving income of ground source heat pump system in summer is 155,900 yuan/year, and the energy saving effect is not significant. It can cooperate with traditional units for cooling in summer. The heating in winter in the park is provided by ground source heat pump system, regenerative electric boiler system and solar energy air conditioning system. Its energy saving benefit is 3.995 million yuan/year which is the main source of energy saving income in the park, with remarkable energy saving effect.

Nursery Pig

HighlightsAn old nursery pig building was retrofitted to potentially improve envelope insulation capacity.A mathematical theory based on coal consumption was established to evaluate energy efficiency of insulation renovation for a nursery pig building.The heat loss of the nursery pig house with 90-mm-thick extruded polystyrene boards was 60% lower than that without the materials.Ground source heat pump and air source heat pump are economical and environmental-friendly heating systems.Abstract. Appropriate renovation of old buildings is critical for energy-efficient pig production. Currently, energy consumption, especially coal consumption, keeps on rising in the production. Therefore, it is essential to develop energy-saving renovation methods for old nursery pig buildings and use cleaner heating energies. A mathematical theory based on coal consumption was established to evaluate energy efficiency of insulation renovation. Two nursery pig houses were tested in this experiment. One was the retrofitted house with the 90-mm-thick extruded polystyrene boards embedded onto outer walls, and the other one was served as a control house without those insulation materials. The results show that the air temperature and inside surface temperature of the retrofitted house were significantly higher than those of the control house in winter. Therefore, though adding insulation layers to walls, the envelope insulation capacity was improved. Meanwhile, the heat loss of the retrofitted house was 60% lower than that of the control house (11.08 W m-2 vs. 27.93 W m-2), when the theoretical ventilation rate was 1560 m3 h-1. In addition, with the prohibition of the coal usage in forseeable future of China, the ground source heat pump and air source heat pump can be economical solutions for heating systems with clean and renewable energy. Keywords: Air source heat pump, Extruded polystyrene board, Ground source heat pump, Heating, Thermal insulation.

Shallow Geothermal Energy

Ground source heat pump system (GSHPS) takes the advantage of shallow geothermal energy, and it can not only provides heat apply but also provide cold making power in a high efficiency and energy saving way. The GSHPS is a low carbon technology and has applied into use. But in China it is a new technology and lack of application. The paper describes the theory of GSHPS, the advantages of GSHPS, the using feasibility of GSHPS and its limitations. Compared with traditional systems, in consideration of system running conditions, energy consumption and the level of environment pollution, the GSHPS can be more efficient and less ecological disruption. And with the developing of the GSHPS technology, it can have a considerable prospect.
