“…Because of compression, the R-22 gas is heated and through the hot R-22 supplying stands (2) of heating system is forced into the hot gas supplying collector (3). From the hot gas-supplying collector (3) the compressed hot gas is distributed among the pipe type air heaters (5), which are hanged on inside walls, on ceiling or stand on the floors of rooms. Because of heat transfer from hot gas of R-22 to inside air of the house, Freon gas condenses and by liquids' stands (6) returns into the liquid's collector (7).…”

Large use of different kinds of fossil fuels in gas, liquid, solid and other forms for heating, ventilating and domestic hot water supplying of houses and heat generation for industrial purposes, in contemporary conditions creates ecological and economical serious problems, contributes to global climate change and requires big efforts and means, as well as long periods, for implementation of expensive conventional heat supply systems. Mentioned problems become even greater because of systematical rise in prices of fossil fuels. The solving of the problem gets harder because of absence of appropriate technology for accomplishing heat generation and its supply without consuming of fossil fuel. The mentioned disadvantages force to develop new generation of heat production and consumption technologies that operate without usage of fossil fuel and simultaneously accomplishes ventilation and domestic hot water supply of houses. For this reason, the authors of this study have decided to develop a new type of heating, ventilation and domestic hot water supplying integrated system, which does not consume at all fossil fuels. The integrated system realized on example of a residential house with 432 m 3 of volume. The study proves energy high efficiency and cost effectiveness of suggested system, as it allows to save 2660 m 3 of fossil fuel per season. Comparison of data shows that specific cost of seasonal heating, referred to 1m 2 of the building is 2.06 times less than for ordinary system.

Abstract:In this article newly developed heating and cooling hybrid system is discussed. The system combines a heat pump, heating boiler and solar air heater. Low temperature source of heat pump is a gas mixture composed of waste warm gases, like inside used ventilation air, flue gases of heating boiler (smock), as well as outside air, heated in solar air heater. The evaporator of heat pump is installed in waste warm gases mixing chamber, aiming at avoiding the main disadvantage of ordinary air sourced heat pump, in case of which the evaporator surface in wintertime is covered with ice crust that obstructs movement of air through the evaporator of heat pump. To solve the problem it is suggested to create a mixture of waste warm gases gathered in a gas mixing chamber and serving as heat source. A method for calculation and design of the new system was developed for both winter heating and summer cooling of a building. The energy and economic investigation based on mathematical model proved rather high cost effectiveness and energy efficiency of developed heating and cooling hybrid system.

Preliminary investigation of the assigned task shows that the energy efficiency of residential houses is conditioned by the quantity of energy, consumed by all internal energy providing systems that serve for creation of comfort microclimate in all rooms of the building. The energy consuming systems of residential houses are: heating, ventilation, air conditioning, domestic hot water providing, tap water supplying systems and other life supporting facilities. If the listed systems consume possibly least quantity of energy or so cold zero net energy, the building can be qualified as energy efficient. The authors of this article try to give right answers how to provide the best, cheapest and ecologically safe solutions of assigned tasks. One of the radical solutions of the problem is the development and use of fossil fuel non-consuming installations of energy production. To overcome of mentioned problems the authors developed new type of thermal and electrical energy generating high efficiency local and central systems. For this reason, the authors of this study decided to develop new generation of heating, ventilation and domestic hot water supplying high efficiency integrated systems.
