A SOLAR ENERGY SYSTEM WITH A DUAL-SOURCE HEAT PUMP AND LONG-TERM STORAGE

At agricultural facilities, the main attention is paid to the formation and maintenance of their microclimate parameters, and mechanization of storage processes. As world experience shows, it is necessary to develop and implement energy-saving systems and the use of renewable energy sources. The authors have developed energy-saving systems based on the heat pump, with upgraded electrical regulators. The developed system (patent 100873), uses thermoelectric elements and a low-potential energy source, to effectively maintain the temperature parameters of the microclimate during long-term storage of potatoes, but it requires a large amount of electricity consumption (30 to 35 kW), so the authors have developed an energy-saving system based on a heat pump (patent 123909). The temperature regime is achieved by using a thermoelectric cooler-heater and an electric heater. The humidifier allows for maintaining the necessary relative air humidity.

The Scottish Government’s commitment for 100% of electricity consumed in Scotland to be from renewable, zero-carbon sources by 2020 continues to drive change in the energy system alongside European and UK targets. The growth of renewables in Scotland is being seen at many scales including industrial, domestic and community generation. In these latter two cases, a transition from the current ‘top down’ energy distribution system to a newer approach is emerging. The work of this paper will look at a ‘bottom up’ view that sees community led distributed energy at its centre. This paper uses the modelling tool HESA to investigate high penetrations of distributed generation in the Angus Region of Scotland. Installations of distributed generation will follow Thousand Flowers transition pathway trajectory, which sees more than 50% of electricity demand being supplied by distributed generation by 2050. From this, insights around the technological and socio-political feasibility, consequences and implications of high penetrations of distributed generation in the UK energy system are presented. Results demonstrate the influence that system change will have on regional and local emission levels under four separate scenarios. It is shown that the penetration of distributed generation requires supplementary installations of reliable and long-term storage alongside utilisation of transmission and transportation infrastructures to maximise the potential of distributed generation and maximise whole system benefits. Importantly, there must be a level of co-ordination and support to realise a shift to a highly distributed energy future to ensure there is a strong economic case with a reliable policy backing.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.
