RU2861670C2RU 2861670 C2RU2861670 C2RU 2861670C2RU-2861670-C2

Abstract

FIELD: water supply. SUBSTANCE: invention relates to water supply systems with decentralized water heating and can be used in independent water supply systems both in domestic and field conditions. In the device, a low-power halogen lamp located inside the coil is used as a heating element, located inside the heat exchanger, and a cold water flow control valve at the inlet to the heat exchanger is additionally installed. EFFECT: reduced dimensions of water heater and increased temperature of heated water due to use of two low-power halogen lamps, as well as ensuring its stable operation by using cold water flow control valve at inlet of heat exchanger. 1 cl, 1 dwg

Description

The invention relates to water supply systems with decentralized water heating and can be used in autonomous water supply systems both at home and in the field. Water is extremely important for the human body; a deficiency can lead to deterioration and even disruption of vital functions. In some areas where people live, both permanently and temporarily, such as shift workers, the issue of a constant water supply is acute. Water sources without sufficient reserve capacity cannot provide a continuous supply. In some areas, water supply is intermittent. The creation of reliable and efficient water supply systems at a modern level is a pressing issue for certain areas and a serious problem for many areas of human habitation and for field conditions. From patent sources, an electric flow-through water heater is known according to Russian patent No. 2668680, class. E03B 7/04, 2018, comprising a water supply line from a water reserve tank, wherein the water supply line is provided with a control panel, a water intake means in the form of a pump, a water heating means made in the form of a heat exchanger, water dispensing means, as well as a pressure sensor, a system operation indicator and a temperature sensor, wherein the pump is included in the water supply line between the water reserve tank and the water dispensing means, wherein the pressure sensor, the system operation indicator and the temperature sensor are respectively connected to the input of the control unit, and the output of the control unit is connected to the pump, wherein an electric lamp (primarily a spotlight) is used as a heating element for heating the water in the heat exchanger, and in the water dispensing means, water-saving nozzles are used, installed at the output of the drain pipe of each water dispensing means, limiting the water flow and ensuring a water consumption within 0.3-1 liter per minute. Well-known autonomous water supply systems are designed with the current global standard for tap water flow—6-9 liters per minute (see "Problems of Space Biology," Vol. XXIV: Chizhov S.V., Sinyak Yu.E., Water Supply for Spacecraft Crews, Moscow: Nauka, 1973, pp. 16, 17). Although this is an excessively high water consumption, virtually no water supply system designers have yet addressed the issue of significantly reducing this figure by increasing the efficiency of the water flowing from the tap, approximately 90% of which is not used to wash the object beneath the stream. A well-known instantaneous electric water heater, according to Russian Patent No. 2668680, Class E03B 7/04, 2018, is insufficiently compact due to the use of an electric or floodlight lamp. This means its dimensions preclude its use in some applications, especially since electric or floodlight lamps are insufficiently efficient at heating water. Furthermore, it lacks a cold water flow control valve at the inlet to the heat exchanger, which prevents the water heater from operating reliably. The technical result of this universal energy-efficient electric flow-through water heater is a reduction in the dimensions of the water heater and an increase in the temperature of the heated water due to the use of two low-power halogen lamps, as well as ensuring its stable operation by using a cold water flow control valve at the inlet to the heat exchanger. The said technical result is achieved by the fact that the design of this universal energy-efficient electric flow-through water heater contains a water supply line from a water reserve tank equipped with a control panel, a water intake means in the form of a pump, a water heating means made in the form of a heat exchanger, water dispensing means, as well as a pressure sensor, a system operation indicator and a temperature sensor, wherein the pump is included in the water supply line between the water reserve tank and the water dispensing means, and the pressure sensor, the system operation indicator and the temperature sensor are connected to the input of the control unit, respectively, and the output of the control unit is connected to the pump, wherein an electric lamp is used as a heating element for heating the water in the heat exchanger, and water-saving nozzles (mainly aerator nozzles) are installed at the outlet of the drain pipe of each water dispensing means, limiting the flow of water and ensuring a water consumption within 0.4-1 liter per minute, two halogen lamps are used as a heating element Low-power heaters, each located inside a coil. Both coils, connected in series, are housed inside a heat exchanger. Furthermore, a cold water flow control valve is installed at the inlet to the heat exchanger. The attached drawing shows the electro-hydraulic diagram of the proposed universal energy-efficient electric flow-through water heater. As shown in the drawing, a universal energy-efficient electric flow-through water heater connected to a water storage tank 1 comprises a water supply line 2 controlled by a control panel 3.
