Full textAs a result of the EU's environmental 2020 goal, the Swedish government and municipal boards has put up internal goals to reduce energy consumption. EU 2020 goal aims to reduce energy consumption in Europe by 20 percent by the year 2020 from that the target was set in 2010. At the municipal level, this has meant that private but mainly public housing properties have been required to review their energy use. The work in this report is based on one of the savings measures that have been taken, which is to supplement existing district heating systems with exhaust air heat pumps. The project aims to develop a calculation model for evaluation and computation for this type of system. To create a reliable basis for decisions, efforts were made to produce just calculations. Existing computational models are focused on economic factors and thus takes little consideration of technological aspects and environmental factors. The aim of the work has been to create a computational model which more closely reflects the real situation and demonstrates a more informative decision basis. The work began with a literature review which included relevant research and basic facts about exhaust air heat pumps and district heating systems. The calculation model has been developed continuously during the project in which new functions and new information constantly has been added. The project has resulted in a working computational model which includes many more parameters than previous reviewed models. Together with the client three sub goals were set up for the model, these were: To intuitively present information and data. To create a transparent structure which is simple to follow. To create a flow through the model, which follows a desired work process. These goals are considered to have been fulfilled in the developed calculation model, however, it's possible to further develop this model. The model could, for example, be supplemented with more automated optimization calculations and be adjusted to handle other kinds of heating systems.

Resumo: O leite é um dos mais importantes produtos da agropecuária nacional, com cerca de 2/3 das propriedades rurais do país destinando-se à pecuária leiteira e com um dos maiores rebanhos do mundo. Apesar da grandiosidade, o setor ainda sofre com a baixa produtividade, os altos custos e a defasagem tecnológica. Como conseqüência, muitos produtores abandonaram suas atividades diante deste novo cenário competitivo. Atualmente, assuntos como uso racional de energia e aplicação intensiva de tecnologia tem sido intensamente discutidos e abordados, e indicados como aspectos importantes para a obtenção de ganhos de produtividade. Desta forma, visou-se neste trabalho avaliar o uso de energia no processamento de leite de três propriedades (leite pasteurizado tipo ¿A¿ e leite cru refrigerado), bem como, a representatividade dos diversos processos no consumo total, assunto este, ainda pouco conhecido e abordado no país. Objetivando ainda, promover a racionalização energética, avaliaram-se os potenciais de aproveitamento de calor de condensação de sistemas de refrigeração existentes para o aquecimento de água de limpeza e higienização, bem como, avaliou-se a viabilidade técnica e econômica da adequação dos sistemas (operação segundo um bomba de calor com geração simultânea de duas fontes térmicas) em substituição ao uso de resistências elétricas. Dentre as proposta, avaliou-se a adequação realizada em um planta piloto em operação. Com o uso de bomba de calor, a redução no consumo total de energia elétrica foi de até 15% com tempos de retorno dos investimentos variando entre 1,3 e 3,7 anos
Abstract: Milk is one of the most important products of Brazilian agriculture, with about 2/3 of the rural properties dedicated to the milkmaid cattle breeding and with one of the largest flocks of the world. In spite of its size, the sector still suffers of low productivity, high costs and tecnological delay. As a consequence, many producers have abandoned its activities before this new competitive technology were introduced. Now, subjects as, the use rational of energy and intensive application of technology has been discussed intensely resulting in productivity gains. In this work , it was seek to evaluate the use of energy for milk processing in three different properties (pasteurized milk type " A " and refrigerated raw milk). It was also evaluated how representativive the several processes in the total consumption were, a problem, still not very well-known and trated in Brazil. To promote the energy rationalization, the potential use of condensation heat of refrigeration systems was evaluated for the cleaning water heating, as well as, the technical and economic viability of the adaptation of the systems was evaluated (operation according to a heat pump with simultaneous generation of cold and heat) in substitution to the use of electric resistances. In the midst of proposals, an adaptation was evaluated in a pilot plant in operation. With the use of heat pumps, there was a decreasing of 15% in the consumption of eletric energy with payback between 1,3 and 3,7 years

Full textDistrict heating is the dominant heating method for apartment buildings in Sweden, and its competitor is the heat pumps that have become increasingly efficient and have a better impact on the market. At the same time, the government has set the 2020 targets in order to reduce and improve Sweden's energy use. As the housing sector accounts for almost 40 percent of Sweden's total energy use, the report's purpose is to study how energy consumption for older homes can be reduced by changing energy systems or by maintaining an existing district heating system, but performing energy efficiency measures. The energy systems studied in this report are district heating, geothermal heat and air-water heat pump. The data used in the report has been largely collected from a apartment building located in Vingåker, owned by Sjötorps hus AB. In order for the results to be more general, two example houses have also been studied; A small house and a larger apartment building. The result of the study shows that the biggest cost of district heating is in operation, and thus this option is also the most expensive for the two major houses. However, both investment costs and maintenance costs are significantly higher for heat pumps and vary depending on where in the country they are to be installed, unexpected downtime and breakdowns. The result also shows that it is not profitable for a small house to switch from an existing district heating system to a heat pump. The conclusion is that energy efficiency should be the first option to reduce the energy consumption of a property, especially as the stock of older houses will increase. No matter how little the energy consumption for the newly built houses are, the older houses will be the largest part of Sweden's total housing stock. The fact that the heat pump uses less energy is no long-term solution to energy efficiency. Instead, energy efficiency actions should be the first option when the desire is reduced energy consumption.
