exergetic efficiency

Exergetic method is a universal way of thermodynamic research of various processes of energy transformation in energy technological systems, to which air conditioning system for clean room belongs. Implementation of exergetic analysis for energy technological system makes it possible to determine the influence of various elements of its system on its work and because of this to increase the effectiveness of work of energy technological system in general.

Rising prices for fuel and energy resources make the problem of using alternative energy sources and energy saving relevant not only for the economy of Ukraine, but also for the world economy. One of the ways to reduce energy consumption is the use of air split-conditioner heat pumps in building heating systems, which are using up to 1 kW of electricity from the grid to transport up to 5 kW of heat energy from the outdoor air to the indoor air. The energy perfection of air split-conditioner heat pumps can best be established only on the basis of the analysis of their exergy efficiency.

In the face of growing shortages and rising prices for fuel and energy resources, the problem of energy conservation and the use of alternative energy sources to solve the problem of reducing energy consumption for the Ukrainian economy become very important. Today, the use of air splitconditioner heat pumps in buildings' heating systems is becoming more common.

In the modern air-conditioning systems with air split-conditioners, equipments, refrigeration agents and processes are occupied the important place, the objective assessment of the degree of its energy perfection which could be defined only on the basis of their exergy analysis. The purpose of the work is to establish exergetic efficiency and losses of exergy in separate elements of the refrigeration machines of the split-conditioners of “Daikin” firm of different cooling capacity.
