Из уровня техники известна система нагрева и охлаждения воды, по заявке на патент US 2009/0113898 [опубл. 07.05.2009, приор. 02.11.2007, МПК F25B 21/02, заявитель Rocky Research Corp]. Указанная система включает в себя емкость для нагрева, емкость для охлаждения, расположенный между двумя емкостями блок нагрева и охлаждения и дополнительный конденсатор, снабженный вентилятором для охлаждения. Емкости состоят из двух замкнутых резервуаров с изоляцией, в которые вставляются бутылки с исходной жидкостью. Блок нагрева и охлаждения состоит из конденсатора, нагревателя и расположенного между ними термоэлектрического преобразователя, где нагреватель соединен с поверхностью нагрева термоэлектрического преобразователя, а конденсатор - с поверхностью охлаждения. Внутри конденсатора и нагревателя находится хладагент. Емкость для охлаждения через трубку присоединена к конденсатору.

The prior art known system for heating and cooling water, according to patent application US 2009/0113898 [publ. 05/07/2009, prior. 11/02/2007, IPC F25B 21/02, Applicant Rocky Research Corp]. This system includes a heating tank, a cooling tank, a heating and cooling unit located between the two tanks, and an additional condenser equipped with a fan for cooling. The tanks consist of two closed tanks with insulation, into which bottles with the original liquid are inserted. The heating and cooling unit consists of a condenser, a heater and a thermoelectric converter located between them, where the heater is connected to the heating surface of the thermoelectric converter, and the condenser is connected to the cooling surface.

Система нагрева и охлаждения воды по патенту US 2009/0113898 работает следующим образом. В емкости для нагрева и для охлаждения устанавливают бутылки с исходной водой, после чего включают системы. При работе термоэлектрического преобразователя от поверхности нагрева тепло передается к нагревателю, где находится хладагент, который при этом разогревается и превращается в пар. Пар через трубку поступает в емкость для нагрева, где происходит передача тепла от хладагента через стенки бутылки к воде, которая нагревается, при этом хладагент конденсируется и по той же трубке, по которой проходит пар, через дополнительный конденсатор, который охлаждается вентилятором, возвращается обратно в нагреватель. Параллельно процессу нагрева происходит процесс охлаждения воды. При работе термоэлектрического преобразователя происходит охлаждение хладагента в конденсаторе. Хладагент поступает в емкость для охлаждения, где через стенки бутылки происходит передача тепла от воды к хладагенту, при этом вода охлаждается. При достижении заданной температуры одна из бутылок или обе бутылки извлекаются потребителем из емкости для нагрева или для охлаждения. Основным недостатком системы по патенту US 2009/0113898 является то, что, нагрев и охлаждение происходит через хладагент, что приводит к потере энергии и снижению эффективности, кроме того использования хладагента неэкологично. The water heating and cooling system according to US 2009/0113898 works as follows. Bottles with source water are installed in the heating and cooling tanks, after which the systems are turned on. During operation of the thermoelectric converter, heat is transferred from the heating surface to the heater, where the refrigerant is located, which is then heated and turns into steam. The steam through the tube enters the heating tank, where heat is transferred from the refrigerant through the walls of the bottle to the water, which is heated, while the refrigerant condenses and, through the same tube through which the steam passes, through an additional condenser, which is cooled by a fan, returns to the heater. In parallel with the heating process, the water is being cooled. When the thermoelectric converter is operating, the refrigerant in the condenser is cooled. The refrigerant enters the cooling tank, where heat is transferred from the water to the refrigerant through the walls of the bottle, while the water is cooled. When the set temperature is reached, one of the bottles or both bottles are removed by the consumer from the tank for heating or for cooling. The main disadvantage of the system according to US 2009/0113898 is that, heating and cooling occurs through the refrigerant, which leads to energy loss and reduced efficiency, in addition, the use of the refrigerant is not environmentally friendly.
Из уровня техники известна система нагрева и охлаждения воды по патенту ЕР 1571121 [опубл. 07.09.2005, приор. 21.05.2005, MIIKB67D 1/08, заявитель Aqua Pyrenees Sas Ste], выбранная заявителем в качестве наиболее близкого аналога. Система состоит из емкости для нагрева, емкости для охлаждения, соединенных трубкой, теплообменника, двух термоэлектрических преобразователей, датчиков температуры и вентилятора. Емкость для нагрева соприкасается с поверхностью нагрева одного из термоэлектрических преобразователей, а его поверхность охлаждения контактирует с теплообменником, который находится в контакте с поверхностью нагрева второго термоэлектрического преобразователя, поверхность охлаждения которого связана с емкостью для охлаждения. Вентилятор охлаждает теплообменник. Комбинация из двух термоэлектрических преобразователей и теплообменника является по своей функции блоком подготовки воды. The prior art system for heating and cooling water according to patent EP 1571121 [publ. 09/07/2005, prior. May 21, 2005, MIIKB67D 1/08, applicant Aqua Pyrenees Sas Ste], selected by the applicant as the closest analogue. The system consists of a heating tank, a cooling tank connected by a tube, a heat exchanger, two thermoelectric converters, temperature sensors and a fan. The heating tank is in contact with the heating surface of one of the thermoelectric converters, and its cooling surface is in contact with the heat exchanger, which is in contact with the heating surface of the second thermoelectric converter, the cooling surface of which is connected to the cooling tank. The fan cools the heat exchanger. The combination of two thermoelectric converters and a heat exchanger is in its function a water treatment unit.
Система нагрева и охлаждения воды по патенту ЕР 1571121 работает следующим образом. В емкость для охлаждения наливают воду, которая по трубке поступает в емкость для нагрева. Таким образом, емкость для охлаждения функционально можно считать линией подачи воды на охлаждение, а емкость для нагрева с трубкой, соединяющей емкости, функционально считать линией подачи воды на нагрев. После заполнения обеих емкостей систему включают. Происходит одновременный процесс нагрева и охлаждения, при этом, за счет теплообменника с вентилятором происходит компенсация разницы температур у поверхностей нагрева и охлаждения у двух термоэлектрических преобразователей. The system for heating and cooling water according to patent EP 1571121 operates as follows. Water is poured into the cooling container, which flows through the tube into the heating container. Thus, the cooling tank can be functionally considered a water supply line for cooling, and the heating tank with a tube connecting the tanks can be functionally considered a water supply line for heating. After filling both containers, the system is switched on. There is a simultaneous process of heating and cooling, while, due to the heat exchanger with a fan, the temperature difference at the heating and cooling surfaces of the two thermoelectric converters is compensated.
Основным недостатком системы нагрева и охлаждения жидкости ЕР 1571121 является наличие емкостей для нагрева и охлаждения. Термоэлектрические преобразователи расположены так, что нагрев или охлаждение воды происходит только в слое у стенки емкости, контактирующей с термоэлектрическим преобразователем, при этом в системе отсутствует какое-либо средство перемешивание воды в емкостях. Таким образом, нагрев и охлаждения происходят неравномерно, поэтому заданная температура воды достигается дольше, по сравнению с равномерным нагревом или охлаждением. Более длительный процесс требует больше энергии, таким образом, система энергетически неэффективна. Длительный процесс нагрева увеличивает время ожидание пользователем воды, что неудобно для пользователя. Кроме того, возможны локальные перегревы или переохлаждение воды, что также неудобно для пользователя и является недостатком системы. The main disadvantage of the EP 1571121 liquid heating and cooling system is the presence of tanks for heating and cooling. Thermoelectric converters are located so that heating or cooling of water occurs only in a layer near the wall of the tank in contact with the thermoelectric converter, while there is no means of mixing water in the tanks in the system. Thus, heating and cooling occur unevenly, so the set water temperature is reached longer than with uniform heating or cooling. A longer process requires more energy, so the system is energy inefficient. A long heating process increases the user's waiting time for water, which is inconvenient for the user. In addition, local overheating or supercooling of water, which is also inconvenient for the user and is a disadvantage of the system.
Задачей изобретения и техническим результатом, достигаемым при его использовании, является разработка новой системы нагрева и охлаждения воды при снижении неравномерности нагрева или охлаждения и сокращении времени ожидания получения пользователем нагретой и/или охлажденной воды. The objective of the invention and the technical result achieved when using it is the development of a new system for heating and cooling water while reducing the unevenness of heating or cooling and reducing the waiting time for the user to receive heated and / or chilled water.
Поставленная задача и требуемый технический результат достигаются тем, что система нагрева и охлаждения воды, включающая линию подачи воды на охлаждение, линию подачи воды на нагрев, которые подключены к блоку подготовки воды, с расположенным в нем термоэлектрическим преобразователем, выполнена с возможностью нагрева и/или охлаждения воды при подаче ее на потребление, при этом блок подготовки воды включает теплообменник для охлаждения воды и теплообменник для нагрева воды, при этом может дополнительно содержать теплообменник для снижения температуры нагретой воды, снабженный средством обдува, и насос. The set task and the required technical result are achieved by the fact that the water heating and cooling system, including the water supply line for cooling, the water supply line for heating, which are connected to the water treatment unit, with a thermoelectric converter located in it, is made with the possibility of heating and / or cooling water when it is supplied for consumption, while the water treatment unit includes a heat exchanger for cooling water and a heat exchanger for heating water, while it may additionally contain a heat exchanger for reducing the temperature of heated water, equipped with a blower, and a pump.
На фигуре 1 представлен пример схемы системы нагрева и охлаждения воды. The figure 1 shows an example of a diagram of a water heating and cooling system.
Заявляемая система нагрева и охлаждения воды в базовом исполнении включает блок подготовки воды (3), линию подачи воды на охлаждение (на фигурах не обозначена) и линию подачи воды на нагрев (на фигурах не обозначена). По своей функции обе указанные линии представляют собой путь воды от источника исходной воды (вход исходной воды) до отбора на потребление нагретой или охлажденной воды соответственно через блок подготовки воды (4). The inventive water heating and cooling system in the basic version includes a water treatment unit (3), a water supply line for cooling (not indicated in the figures) and a water supply line for heating (not indicated in the figures). In their function, both of these lines represent the path of water from the source of source water (source water inlet) to the selection for consumption of heated or chilled water, respectively, through the water treatment unit (4).
Блок подготовки воды (4) включает в себя теплообменник для охлаждения воды (2), теплообменник для нагрева воды (3) и, по меньшей мере, один термоэлектрический преобразователь (1) или комбинацию, по меньшей мере, двух термоэлектрических преобразователей. Теплообменник для охлаждения воды (2) и теплообменник для нагрева воды (3) представляют собой радиаторы из теплопроводного материала, например, но не ограничиваясь перечисленными вариантами, нержавеющей стали, латуни, пластика. Теплообменник для нагрева воды (3) расположен вдоль поверхности нагрева термоэлектрического преобразователя (1). Теплообменник для охлаждения воды (2) расположен вдоль поверхности охлаждения термоэлектрического преобразователя (1). Дополнительно блок подготовки воды (4) может быть снабжен теплоизоляций (на фигуре не представлена). В рамках отличительных признаков система нагрева и охлаждения воды работает следующим образом. Пользователь включает систему на отбор нагретой и/или охлажденной воды. При этом вода от источника по линии подачи воды на нагрев (на фигурах не обозначена) и/или линии подачи воды на охлаждения (на фигурах не обозначена) поступает в блок подготовки воды (4), где проходит через теплообменник для нагрева воды (3) и/или теплообменник для охлаждения воды (2) вдоль поверхности нагрева и/или охлаждения термоэлектрического преобразователя (1), при этом происходит нагрев и/или охлаждение воды. Нагретая и/или охлажденная вода поступают пользователю на потребления. После получения необходимого количества нагретой и/или очищенной воды пользователь выключает систему. При этом, в отличие от наиболее близкого аналога, процесс нагрева и/или охлаждения воды идет предпочтительно параллельно с подачей воды на потребление, пользователю не требуется ждать, пока нагреется и/или охладиться вся вода в емкости для нагрева и/или охлаждения воды. При этом перемещение воды внутри теплообменников происходит в турбулентном потоке, что обеспечивает перемешивание, это приводит к более быстрому распределению температуры в объеме воды. Кроме того, толщина слоя воды в теплообменники для нагрева воды (3) и/или теплообменники для охлаждения воды (2) меньше, чем в соответствующих емкостях наиболее близкого аналога. Таким образом, снижается риск локального перегрева и/или переохлаждения воды. Таким образом, нагрев или охлаждение воды происходит быстрее и равномернее. Таким образом, изобретение решает поставленную задачу и достигается требуемый технический результат. The water treatment unit (4) includes a heat exchanger for cooling water (2), a heat exchanger for heating water (3) and at least one thermoelectric converter (1) or a combination of at least two thermoelectric converters. The heat exchanger for cooling water (2) and the heat exchanger for heating water (3) are radiators made of heat-conducting material, for example, but not limited to the above options, stainless steel, brass, plastic. The heat exchanger for water heating (3) is located along the heating surface of the thermoelectric converter (1). The heat exchanger for water cooling (2) is located along the cooling surface of the thermoelectric converter (1). Additionally, the water treatment unit (4) can be provided with thermal insulation (not shown in the figure). As part of the distinguishing features, the water heating and cooling system operates as follows. The user turns on the system for the extraction of heated and / or chilled water. In this case, water from the source through the water supply line for heating (not indicated in the figures) and / or the water supply line for cooling (not indicated in the figures) enters the water treatment unit (4), where it passes through a heat exchanger for heating water (3) and/or a heat exchanger for cooling water (2) along the heating and/or cooling surface of the thermoelectric converter (1), whereby water is heated and/or cooled. Heated and/or chilled water is supplied to the user for consumption. After receiving the required amount of heated and / or purified water, the user turns off the system. At the same time, unlike the closest analogue, the process of heating and/or cooling water is preferably carried out in parallel with the supply of water for consumption, the user does not need to wait until all the water in the tank for heating and/or cooling water is heated and/or cooled. At the same time, the movement of water inside the heat exchangers occurs in a turbulent flow, which ensures mixing, which leads to a faster temperature distribution in the volume of water. In addition, the thickness of the water layer in the heat exchangers for heating water (3) and/or heat exchangers for cooling water (2) is less than in the corresponding tanks of the closest analogue. Thus, the risk of local overheating and/or hypothermia of water is reduced. Thus, heating or cooling of water occurs faster and more evenly. Thus, the invention solves the problem and achieves the desired technical result.
Дополнительно к базовой схеме система нагрева и охлаждения воды может включать теплообменник для снижения температуры нагретой воды (5), снабженный средством обдува (6), и насос (8). Теплообменник для снижения температуры нагретой воды (5) выполнен в виде радиатора из теплопроводного материала, например, но не ограничиваясь перечисленными вариантами, нержавеющей стали, латуни, пластика. Средство обдува (6) выполнено в виде, например, вентилятора или компрессора. В случае, когда пользователь отбирает на потребление охлажденной воды больше, чем нагретой, указанные элементы являются дополнительной защитой пользователя. Нагретая вода из блока подготовки воды (4) поступает в теплообменник для снижения температуры нагретой воды (5), где за счет обдува воздухом при помощи средства обдува (6) снижается температура воды, после чего за счет насоса (8) вода возвращается в блок подготовки воды (1), где смешивается с исходной водой. In addition to the basic scheme, the water heating and cooling system may include a heat exchanger to reduce the temperature of the heated water (5), equipped with a blower (6), and a pump (8). The heat exchanger for reducing the temperature of heated water (5) is made in the form of a heat-conducting material radiator, for example, but not limited to the above options, stainless steel, brass, plastic. The blowing means (6) is made in the form of, for example, a fan or a compressor. In the event that the user takes more chilled water than heated water, these elements are additional protection for the user. The heated water from the water treatment unit (4) enters the heat exchanger to reduce the temperature of the heated water (5), where, due to air blowing, the water temperature decreases with the help of the blower (6), after which the water returns to the treatment unit due to the pump (8). water (1), where it is mixed with the source water.
Дополнительно система может быть снабжена, по меньшей мере, одним датчиком температуры (7), позволяющим пользователю получать информацию о температуре воды. Дополнительно система может содержать контроллер (на фигурах не представлен), который регулирует подачу воды от источника воды и/или работу насоса (8), ориентируясь на показания датчика температуры. Additionally, the system can be equipped with at least one temperature sensor (7) that allows the user to receive information about the water temperature. Additionally, the system may contain a controller (not shown in the figures), which regulates the water supply from the water source and/or the operation of the pump (8), focusing on the readings of the temperature sensor.
Дополнительно система может содержать клапан нагретой воды (10) и/или клапан охлажденной воды (12). Указанные клапаны позволяют регулировать поток воды на потребление. Additionally, the system may include a hot water valve (10) and/or a chilled water valve (12). These valves allow you to regulate the flow of water for consumption.
Дополнительно система может содержать, по меньшей мере, один обратный клапан (9), исключающие течение нагретой воды в противотоке к источнику воду. Данные клапаны (9) необходимы в случае, когда требуется защита источника воды от попадания нагретой воды. Например, в случае, когда система нагрева и охлаждения воды является частью системы водоподготовки или системы приготовления напитков, при этом источником воды для системы нагрева и охлаждения воды является система очистки воды. Additionally, the system may contain at least one check valve (9), which excludes the flow of heated water in countercurrent to the water source. These valves (9) are required when it is necessary to protect the water source from the ingress of heated water. For example, in the case where the water heating and cooling system is part of a water treatment system or a beverage preparation system, the water source for the water heating and cooling system is a water purification system.
Дополнительно система может содержать проточный нагреватель (11), предназначенный для дополнительного нагрева нагретой воды. Например, в случае, когда система нагрева и охлаждения воды является частью системы приготовления напитков, например кофеварки. В этом случае, поскольку комфортная для потребления температура нагретой воды ниже температуры, требуемой для приготовления кофе, проточный нагреватель (11) дополнительно нагревает воды до температуры, необходимой для приготовления напитка. Additionally, the system may contain a flow heater (11) designed for additional heating of heated water. For example, in the case where the water heating and cooling system is part of a beverage preparation system, such as a coffee maker. In this case, since the temperature of the heated water that is comfortable for consumption is lower than the temperature required for making coffee, the flow heater (11) additionally heats the water to the temperature required for making a drink.
