Abstract

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 m3 of volume. The study proves energy high efficiency and cost effectiveness of suggested system, as it allows to save 2660 m3 of fossil fuel per season. Comparison of data shows that specific cost of seasonal heating, referred to 1m2 of the building is 2.06 times less than for ordinary system.

Highlights

The problem of fossil fuels usage elimination from practice aiming at amelioration of environmental conditions [1] and living standards have been one of main goals of human beings as a mean for growth in prosperity
Detailed studies of well-known heating system’s structures, operation principles, kinds of consumed fuels’, energy and cost effectiveness and other constructive and operational features it is concluded that developed fossil fuels non - consuming heating, ventilation and domestic hot water providing integrated system is publically issued and discussed first time
The critical advantage of developed heat supply integrated system is the prevention of surrounding environment from pollution, because it does not use at all natural fossil fuel

Summary

Introduction

The problem of fossil fuels usage elimination from practice aiming at amelioration of environmental conditions [1] and living standards have been one of main goals of human beings as a mean for growth in prosperity. The authors of this article made efforts to develop new type of heat supplying system, which is named fossil fuels non-consuming heating, ventilating and domestic hot water providing integrated system. 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 exchange with inside air, the compressed refrigerant gas is condensed in pipe type air heater tubes and sequentially passes through throttling valve (8) and heat exchanger (9), where, by absorbing heat from hot water, the liquid refrigerant is evaporated and the compressor (1) sucks the vapor of R-22 for repeating above described processes. The domestic hot water is prepared in heat exchanger (14) which is installed in the basement of the house, and is connected with tap water (16) and domestic hot water (15) supplying pipelines
