Methodological aspects of optimization of energy consump-tion costs of low-rise buildings with a built-in air heat pump

Abstract

Objective. The rational use of fuel and energy resources is one of the urgent problems. One of the promising ways to solve this problem is the use of environmentally friendly energy-saving air source heat pumps based on the use of non-traditional energy sources. The use of such innovative energy-saving technologies requires not only modern architectural and planning, design and engineering solutions, but also sound methodological recommendations for as-sessing their energy efficiency and feasibility. The article presents a methodology for calculating the consumed electrical energy and heat generation, as well as the seasonal indicator of energy efficiency in the operation of an air source heat pump.Method. The technique takes into account, as input data, experimental data from tests of high-voltage heat pumps in terms of heat output depending on the change in the temperature of the source of low-grade heat and the temperature regime of the coolant.Result. The need to develop a methodology is due to the shortcomings in the regulatory documents of the methodological basis for optimizing energy costs and heat generation by heat pumps. The accuracy of calculating the operating costs that will occur during the heating period of the air source heat pump (AHP) depends on the correct accounting of the required heat load of a low-rise building and the consumption of electricity to ensure it.Conclusion. This technique can be applied not only to calculate the annual operating costs of using a heat pump and determine the structure of energy consumption (thermal and electrical), but also to optimize the energy parameters of HHP with an assessment of the energy efficiency of different options for their configurations.
