Abstract
This study is aimed at the development and designing of a combined heat exchange installation (generator of an absorption refrigeration machine (AHM)/heat pump condenser) in an air-conditioning complex combining a refrigeration machine, a heat pump, and solar collectors. We propose an original schematic decision ensuring the combination of functioning of the generator, the condenser, and the heat pump in a single complex. Flow diagrams of working regimes of the air-conditioning complex are calculated. The technical aspect of the AHM generator is developed and the method for calculating its thermal and technical characteristic is proposed, which makes it possible to take into account the simultaneously occurring processes of boiling of a dilute lithium bromide solution, steam evaporation, and condensation of superheated freon R600a vapor in a single hydraulic loop of solar collectors and heat pump. This decision allows us to refute traditional multiloop systems in which different working bodies circulate, and the heat-transfer processes are implemented with the help of intermediate devices. As a result, it becomes possible to optimize the mass and size characteristics of the entire complex, to reduce the number of basic devices, and to increase the energy efficiency of the entire air-conditioning system. We propose that one and the same freon R600a (isobutane) be used as the heating agent of the solar power plant, the cooling agent of the heat pump, and the heat-accumulating substance. We report on the results of thermal and checking calculations of the combined heat exchange installation. The sizes of the system and its operation conditions are evaluated; the heat-transfer coefficients, expenditures, and the working parameters of cooling agents as well as the thermal power of the apparatus are determined. The significance of the results lies in the development and formation of the technical aspect of the combined heat exchanger, the proof of its high energy and technological efficiency, and the development of recommendations for its designing in complex systems of centralized air-conditioning.
