Title : The use of waste heat from cooling milk for heating a rural residential building
Key words : waste heat, milk, heat pump, heat demand of a building, investment costs, exploitation costs
Summary :

The paper presents a theoretical discussion on the use of waste heat from cooling milk for heating purposes compared to the selected conventional technologies of producing heat in a rural residential building. Moreover, the article presents approximate results of the investment and exploitation costs account. The use of waste heat from technological processes is one of the elements of limiting the fuel consumption, which becomes more and more expensive with every year and in a wider perspective it influences the improvement of the natural environment condition through decrease of CO 2 emission to atmosphere. Waste heat from the process of cooling milk constitutes a significant source of thermal energy in the energy balance of farms, where diary cattle is bred. For many years on the national market there have been systems enabling recovery of thermal energy collected from the cooled milk and used for preparation of warm utility water, which may be used for production purposes in a cowshed or in a farm, depending on its amount and demand. Whereas, as it results from the literature review, there are no further information on the use of waste heat from cooling milk in installations of the central heating. Therefore, the purpose of the article is to complement knowledge in this scope.
