RU65623U1 - HOT WATER SUPPLY SYSTEM WITH REDUCED ENERGY CARRIER CONSUMPTION - Google Patents

Abstract

The utility model relates to the field of thermal power, is used in combination with boiler houses operating on any type of fuel or electricity. EFFECT: reduction of greenhouse gas emissions into the atmosphere, saving of fuel consumption (for electric boiler rooms - energy saving) in the process of heating water or generating steam for domestic, industrial and other needs. Fuel economy is achieved by pre-heating cold water in the solar collector, before it is finally heated in the boiler room. At the same time re-equipment of a boiler room is not required. Under some conditions, fuel economy can reach several tens of percent.

Description

The utility model relates to the field of energy and is used in combination with boiler houses operating on any type of fuel or electricity.

EFFECT: reduction of greenhouse gas emissions into the atmosphere, saving of fuel consumption (for electric boiler rooms - energy saving) in the process of heating water or generating steam for domestic, industrial and other needs.

The prior art hot water supply system, where, using the heat of combustion of the coolant, or the use of electricity, is the heating of cold water to the required temperature. The described system has greater efficiency due to the preheating of cold water in the solar collector.

The hot water supply system uses pre-heating of cold water in a flat or any other solar heat exchanger (solar collector) and its subsequent supply to the boiler room. Depending on the area of the solar collector, the consumption of hot water, weather conditions and time of day, time of year, the heating of water in the solar collector ranges from fractions of a degree to several tens of degrees. In figure 1, cold water from a well (1) or water supply (2), through an open valve (4), valve (5) is closed, enters the solar collector (3), where under the influence of energy emitted by the sun (6) Heats up. Further, the pre-heated water through the supply system (7) enters the boiler room (8), where it is heated to the required temperature, at the outlet of the boiler room (9), hot water is supplied to the consumer. The sensor (10) controls the ambient temperature and the amount of energy emitted by the sun and in the case when the energy emitted by the sun is not enough to increase the temperature of cold water - the automation system (11) opens the valve (5) and closes the valve (4) to prevent water cooling in solar collector. When the ambient temperature drops below the cold water temperature at the inlet of the solar collector, the automation system shunts the solar collector and drains the water from the solar collector to prevent it from defrosting. In the southern latitudes and regions with greater solar activity, the operation of the invention will be most effective.

Implementation of the described system is possible by supplementing the usual boiler room with a solar collector, a system for transporting preheated water from the collector to the boiler room, and a group of valves with an automation system. At the same time, re-equipment of the boiler house itself is not required. The solar collector can be located on the roof of the boiler room, the surrounding area or in others. Depending on the geographical latitude surrounding the building, the solar collector should be positioned so that its efficiency is maximum.
