Description

HOT WATER SAVING SYSTEM Technical Field:

The presented invention relates to a hot water saving system that minimizes water consumption and facilitates the use of hot water. State of the Art:

People in daily life, cleaning purposes (shower, makeup, hand, face, foot cleaning, ablution and kitchen dishwasher, etc.), used, clean, hot water boiler, water heater, water heater, boiler, floor exchanger, solar energy panel, system and device is supplied from etc. The hot water produced in the device and system is transported by pipes from the production point (heat source) to the consumption point (tap). As soon as the faucet is turned on, the hot water travels a certain distance from its source through pipes and reaches the faucet. When there is no water use, water waits in the pipes, loses its heat and cools down. It pushes the water that has cooled down and reaches the tap, waiting for it to come to the tap from the hot water source earlier. In this case, cold water is not used and goes to the trash. As an example of this situation; when you enter the shower, turn on the faucet and wait for the cold water to run out and the hot water to come in. The amount of wasted water according to this account, the diameter of the pipe from the boiler in the apartment of 70 m² shower mixer o20 mm, the average time for a given distance 10 meters of water wasted while waiting for hot water to arrive for a shower about 5 liters in an apartment of 70 m², two adults and a child use the shower once a day, one of them wastes 1,800 liters of water per 1 year, 150 liters in 30 days, 1,800 liters when showering, and this amount is only for a single-digit house. The utility model application TR201301593 describes the ’’Hot water saving system in homes". Unlike the known bathrooms and sinks, the hot water pipes coming out of the boiler/geyser are extended to the taps as in figure-1 and figure-2, and the taps are connected to the "T" part here to prevent hot water loss. The last point after a hot water pipe boiler/water heater with the cold water mains pipe that feeds the Global three-way electric actuated gate/solenoid valve or a two-way global actuated gate/solenoid valve combined with the controlled closed-loop system by creating a closed-circuit recirculation executed in icens known such as the opening of the faucet in the bathroom water pump boiler/water heater is to run for.

The circulation line in the above-mentioned application is quite long, and the amount of water in it must circulate all the points and come back to the heat source. This, in turn, causes a high amount of water to be heated, increasing energy consumption. In addition, it creates a waste of time because the circulation will be completed in a very long time. There is no safety valve, there may be a risk of explosion in the installation as a result of sudden pressure rises. In addition, in the invention, there is no mechanism to automatically turn off the system in cases where water from the city network is reduced or absent. In case of malfunctions, the system is constantly working and causes serious damage. The heat sensor in the system was preferred as a surface reader over a metal part at the pump outlet and the system was tried to be controlled according to the heat value on the metal. Moreover, the present invention provides for the possibility of use only in residential premises (houses). As a result, a new technology is needed that can overcome the disadvantages mentioned above. Description of the Invention:

The invention relates to the fact that the main purpose of our heating system is to prevent water and energy consumption and to increase the comfort level in terms of the use of hot water. We achieve this goal by means of the circulation panel, solenoid valve and heat sensor located in the system. The invention is designed in such a way that the circulation line in our system is within the standards, the solenoid valve and the immersion ntc (heat sensor) located at each point of use, due to which the circulation system will be activated only for that point if hot water is needed for which point of use, and the system will be turned off when the heat sensor detects hot water. The energy consumption will be lower, the transportation time to hot water will be shorter.

The invention includes a safety valve in our control system in order to prevent damage to the installation as a result of dangerous pressure increases. Automatic evacuation of water is provided after an increase in pressure.

In the invention, due to the pressure sensor located at the inlet of the circulation pump, it detects when there is no water in the city network and the system is disabled.

As mentioned in the invention, the main control panel is programmed for up to 3 minutes via the motherboard and controls every movement of its system with the help of sensors. If the heat source (devices) itself is faulty, it does not heat the water, the cold water will circulate in the circulation and stop the system, when the heat sensor detects the temperature and cannot stop the circulation, the main control module turns off the system on its own when the 3-minute period expires and switches to fault mode. The control panel located at each point of use is also illuminated and gives an audible 10-second cutoff warning. If the city water supply is disconnected from the mains, the pressure sensor detects this situation and does not start the system and notifies of a malfunction in the same way. Solar energy panel in the tank (in the tank) - heated hot water of its own weight and installation (to the point of use) instead of a pressure sensor for coming electronic float reservoir (tank) and the temperature to be controlled water level inside the reservoir (storage) in water temperature and a sufficient level of no value (blank, incomplete, or 35C°below) if you do not run the system, but the failure mode. Freezing in the installation, clogging of the line from corrosion, etc. in case of a malfunction such as circulation is not completed and hot water does not reach the heat sensor, the system switches itself off and goes into fault mode at the end of this time because the motherboard that controls the system is programmed to work for 3 minutes (programmable time). The heat sensor placed next to the 12v solenoid valve (electric on-off valve) located at each point of use directly detects the heat value of the water in the line and ensures that the circulation works only for that point. Pressing the button simultaneously from two separate control panels opens the solenoid valve of the point first pressed to this point circulation begins when the heat sensor detects hot water, closes the solenoid valve, and then opens the solenoid valve at the second point of use pressed to the button circulation continues there and the system turns off when heat is detected.

The subject of the invention, our system is villa, residential, public housing, workplace (hairdresser, gym, hostel, hotel), etc. it is designed to be adapted to all heat sources (devices and systems) such as boiler, geyser, thermosiphon, boiler, floor exchanger, solar energy system in places.

Our invention can be used by using a valve with a mechanical thermostat on the system at other points of use (in addition to the drain (washing) tap of the toilet bowl and keeping the water temperature constant at 30C°. Solenoid valve, mechanical thermostat valve and control panel can be designed and manufactured as a single unit on a surface or built-in.

The subject of the invention is a system, hot water supply, (C) when there is not enough pressure at the entrance in cold water, hot water supply, (C)the circulation pump (1) from one of the sensors or the system in case of failure of the main control panel closes automatically and the failure mode last (7) comprises. The circulation panels (1) included in the invention operate independently of each other.

Detailed Description of The Invention:

Basically, the invention of the components of the system; the circulation pump (1) Pressure Sensor (2), Temperature Sensor (3), safety valve (4) one-way check valve (5) solenoid valve (6) Main Control Panel (7), circulating panel (8), the circulation Line (9), mechanical thermostatic valve (10) and the control cable (11).

The schematic image of the system subject to the invention is shown in Figure 1. The mentioned hot water supply (C) may belong to any of the devices used for heating cold water, such as combi boiler, water heater, thermosiphon, boiler, floor exchanger.

The working principle of the system in question is as follows; the point of use (faucet, toilet or sink) in the circulation panel (8) and pressing the start button 1 time is left red LED light on the module that belong to that section comes on the solenoid valve (6) to the circulation Line (9) opens and the circulation pump (1) installation of hot water in the cold water source (C) when taking the hot water source, (C) use hot water to the point of 25-35 seconds (which varies according to the length of the line () sends. The heat sensor (3) at the outlet of the solenoid valve (6) located at each point of use detects that hot water has reached the point of use and turns off the system. A sound warning for 5 seconds with a green light on the circulation panel (8) indicates that the hot water is ready for use by giving a warning. As soon as the faucet is turned on, the hot water is ready, now the hot water comes from its own system, that is, from the hot water supply (C), there is no need for circulation. The system remains turned off until the next use. At which point of use the start button is pressed, the circulation works for that point. The pressure sensor (2) located at the cold-water inlet of the devices (boiler, water heater, etc.) does not operate the system when there is not enough pressure in the installation (if the mains water is disconnected). The heat source devices (boiler, geyser, etc.) do not heat the water in case of failure, and the main control panel (7) with a heat sensor that reads that the circulation has been completed (3) and the motherboard that runs the system when hot water does not arrive is programmed for 3 minutes (programmed according to the size of the system). When it cannot detect sufficient heat and turn off the circulation during this time, the system turns itself off after 3 minutes and switches to fault mode, and the red led, green led and buzzer on the circulation panel (8) give a 10-second cut-off light and an audible warning.

Devices such as a boiler and a gas water heater detect the passage of water through a flow sensor inside the device when the hot water tap is turned on and activate the device to heat the water. The circulation pump (1), circulation line (9) > heat sensor (3) > one-way check valve (5) > T pipe are adapted to the cold-water inlet of the hot water supply (C) in the order of the pipe part in our invention system. Thus, the pump that pushes the cold water it draws from the circulation into the device performs a flow inside the device and activates the device to heat the water.

In systems such as thermosiphon, it pre-heats the water in its chambers and hibernates it at 40-60-1001t and above. The circulation pump of the hot water saving system (1) can be connected to the cold-water inlet by the same system as in the boiler and geyser. The central system, such as villas, boarding houses, gyms, boutique hotels, etc., has a circulation line (9) and a circulation pump (1) in the heating system with a boiler, but it works 24/7 without stopping. The boiler circulation pump (1) can be controlled from the hot water saving system and thus saves electricity when the circulation pump (1) does not work when it is not needed.

Floor heat exchangers in large residential buildings of 10 apartments and more, tap water is heated by a heat exchanger from the hot water available in the main column of the central heating system. As with others, the hot water saving system can be easily adapted to the existing system.

Since the fan controls the inlet of cold water in the tank where hot water is hibernated in solar energy panels, the return of circulation is made by an external inlet to the tank. Of the panel in the store solar energy-heated hot water of its own weight and installation (to the point of use) for the pressure sensor (2) electronic level instead of the knob (E) to the reservoir (tank) and the temperature to be controlled water level inside the reservoir (storage) in water temperature and a sufficient level of no value (blank, incomplete, or 35C°below) if you do not run the system, but the failure mode circulating through the panel (8) gives audible and visual warning. If the circulation is not completed and the hot water does not reach the heat sensor (3), the main control panel (7) that controls the system is programmed to work for 3 minutes (programmable time), because at the end of this time, the system turns itself off and goes into fault mode.

The electronic stream motherboard and circulation pump (1), which are the main parts of the system subject to the invention, can be designed as a single module and device manufacturers can adapt it to the device, since it will not take up much space, or a connection to an externally installed system can be made.

The circulation panel (8), which will be positioned at each point of use, can be designed together with normal and built-in (under-plaster) batteries and manufactured as a single unit. Our system, which is the subject of the invention, also provides the use of hot water in toilet bowls. In addition to the system at other points of use, it can be used by adding a mechanical thermostat valve (10) to the toilet seat's drain faucet and keeping it October at 30C°. Solenoid valve (6), mechanical thermostat valve (10) and circulation panel (8) can be designed and manufactured as a single unit on a surface or built in.
