Abstract

The utility model relates to water heating devices and can be used to provide autonomous hot water supply in private houses and apartments that are not connected to centralized hot water supply systems. The technical challenge facing the authors is to provide convenience and reduce consumer costs and the ability to use any coolant or any heating device to provide hot water without sudden changes in water temperature.

This problem is solved by the fact that a heat exchanger is provided in the design of the layer-by-layer heating boiler. The boiler consists of a heat-insulated tank 1, cold water enters it through inlet 3, and hot water enters the consumer through outlet 6, through pipe 4 by means of a circulation pump 2, cold water from the bottom of the tank enters heat exchanger 11, located in the same housing with the tank, through the pipe 5 hot water from the heat exchanger returns to the top of the tank. Through pipes 12 and 13, the heat exchanger is connected to an external source of any coolant.

Description

The utility model relates to water heating devices and can be used to provide autonomous hot water supply in private houses and apartments that are not connected to centralized hot water supply systems.

Devices for producing hot water in the absence of connection to centralized hot water supply systems are known, in particular, instantaneous electric heaters, double-circuit gas boilers, indirect heating boilers connected to single-circuit gas boilers.

The main disadvantage of the known autonomous hot water supply systems is a sharp drop in temperature with an increase in consumption (flow-through electric heaters, double-circuit gas boilers), or a significant increase in capital costs (boilers of indirect heating).

The closest prototype analogue is a layered heating boiler, for example, GALMET FUSION (https://teplohorosho.ru/documentation/Instrukciia-GALMET-FUSION.pdf, 11/22/2017), Vaillant actoSTOR (https://www.vaillant.ru /downloads/documents/instructions/vodonagrevately/0020 184043-01-vih-ql-75b-ba-406122.pdf, 03/15/2018) presented on the market, in which water is arranged in layers - hot at the top, cold at the bottom, due to natural difference in the density of hot and cold water, hot water is supplied to the consumer's taps from the top of the tank, cold water enters the bottom, heating is provided by distillation of water from the bottom to the top through an external heat exchanger - a double-circuit gas boiler. The main disadvantages in this case are the rather high price of double-circuit gas boilers, compared with single-circuit ones, as well as the complexity of installation.

The technical challenge facing the authors is to provide convenience and reduce consumer costs when providing hot water.

This problem is solved by the fact that a heat exchanger is provided in the design of the layer-by-layer heating boiler. The heat exchanger is connected to a source of thermal energy: a boiler (gas, solid fuel or liquid fuel), an air conditioner connected according to the heat pump scheme, a heat pump, etc. In this case, the second circuit of the heat exchanger works to heat water in the layer-by-layer heating boiler.

As a result, along with the main advantage of a layered heating boiler - the absence of hot water temperature drops with an increase in consumption - it turns out to use any source of thermal energy.

The essence of the utility model is illustrated by the drawing.

The drawing shows a diagram of a layered heating boiler with a built-in heat exchanger. The boiler consists of a body (14) with a heat-insulated tank (1), cold water into which enters through the inlet (3), and hot water enters the consumer through the outlet (6), through the branch pipe (4) by means of a circulation pump (2) cold water from the bottom of the tank enters the heat exchanger (11), located in the same housing with the tank, hot water from the heat exchanger returns to the upper part of the tank through the branch pipe (5). Through pipes (12) and (13) the heat exchanger is connected to an external source of thermal energy. Level sensor (7) of water in the tank, non-return valves (8), safety valve (10) and expansion tank (9) are designed to ensure the operation of the device.

Thus, this device provides the possibility of using any source of thermal energy, and also provides hot water supply without changes in water temperature when the flow rate changes.
