Description

DESCRIPTION
A DEVICE FOR UNDERGROUND HEATING SYSTEMS
Technical Field
The invention relates to a device that performs the distribution process of hot water obtained from a heat source to the underground piping system installed in closed spaces for heating purposes.
The invention specifically relates to a heating collector that is developed to enable both water heating and hot water distribution processes to be performed using a single device, instead of using any type of boiler/combi/heat pump as a heat source for supplying hot water circulating in the underground piping system installed for heating purposes in closed spaces.
The invention specifically relates to a device that performs the distribution process of hot water to an underground piping in underground heating system that carry out the process of heating the indoor environment, wherein; in order to provide a single device that performs both water heating and distribution of hot water instead of using the boiler/combustion unit/heat pump as one of the heat sources that provide the circulation of hot water through the underground piping in the underground heating system; the device comprises a heating collector having a collector unit and an electric heating unit, wherein: the collector unit is configured to establish a closed-loop water circulation in the underground piping by operating a circulation pump connected to the body via a helix, drawing the circulated water from a distribution tank through a suction pipe, and directing it to a return tank, the electric heating unit is configured to perform indoor environment heating without the need for an external heat source by heating a heating area with a resistor located thereon and sending it through the underground piping via the collector unit.
Prior Art
Underground heating systems are used for heating in closed spaces. Underground heating systems consist of a heat source from any type of boiler/combi/heat pump, underground piping installed in the ground, and two separate collectors that perform both water distribution and return water collection between the underground piping and the heat source.
In the operation of the underground heating system, the water heated in a closed loop through the heat obtained from the heat source circulates in the underground piping by the movement provided by the circulation pump connected to the heat source. The underground piping is laid in the ground, and while the distribution of the heated water is carried out through the distribution collector, the return process of the cooled water circulating in the underground piping is performed through the return collector to redirect it back to the heat source. This process continues in a closed loop, thus heating the closed spaces.
In the prior art, as mentioned above, external heat sources are used in underground heating systems. The heat source can be a boiler running on natural gas/LPG, a solid/liquid fuel boiler, or a heat pump. This situation brings along many drawbacks, such as the cost of the heat source, excessive space requirements due to the size of the heat source, and increased maintenance/repair installation costs depending on the structure of the heat source. The use of two separate collectors in the system also leads to problems such as collector procurement, thus heat loss, and increased installation/mounting costs.
Furthermore, the operation of the system requires high pressure for combi boilers and heat pumps, and when there is no pressure, the heat source cannot perform the closed-loop water heating process. In the case of a solid/liquid fuel boiler as the heat source, the installation process of the heat source requires external expansion tanks and piping. There is a risk of explosion due to excessive heat rise during the operation of the heat source resulting in pressure.
In order to eliminate the drawbacks associated with the use of two separate collectors in the prior art underground heating systems, we have developed a utility model with the number TR2021/015195 titled 'STRUCTURE OF THE COLLECTOR USED IN UNDERGROUND HEATING SYSTEMS.' The summary section of the mentioned application states the following: “The invention relates to a collector belonging to underground heating systems, which enables the heating of the ambient space through the circulation of heated water in the underground piping, obtained from a heat source that can be any type, such as solid, liquid, gas-fired boiler/combi, solar-powered, or electric, by receiving movement from the circulation pump. The feature of the collector is to perform heat and pressure balancing operations by transmitting heated water to the entire underground piping through the collector, thus improving the operating efficiency of the system and minimizing energy/fuel consumption through the implemented improvements.” Although the requirement for two separate collectors in the underground heating system has been eliminated according to the summary and content of the related application, there is still a need for an external heat source in the system. As mentioned earlier, this situation brings along various drawbacks such as the cost of the heat source, excessive space requirements due to the size of the heat source, and increased maintenance/repair installation costs depending on the structure of the heat source. As a result, due to the drawbacks encountered in the prior art and described above, there is a necessity for further developments in the relevant technical field.

The main inlet connection (1 11 ) is connected to the municipal water supply, and the power cable (250) is connected to the electrical grid.
After the installation of the underground heating system (Y) is completed, water is supplied to the body (1 10) of the heating collector (A) and the underground piping (Y1 ) from the municipal water supply. At this stage, air and pressure adjustments within the underground piping (Y1 ) and the body (1 10) are performed through the safety valve connection (112) connected to the safety valve. The desired room temperature is adjusted using the control buttons (242) on the control board (240) of the electric heating unit (200). As shown in Figures 2, 3, and 4, the circulation pump (121 ) of the heating collector (A), along with the helix (120), takes water from the return tank (1 13) through the water transfer gaps (115) and sends it to the distribution tank (114) through another water transfer gap (115). In this way, the circulating water is directed to the underground piping (Y1 ) through the piping distribution connection (1 17). As mentioned, during the water circulation process, a relatively low pressure of approximately 250 mbar (millibar) is generated in the distribution tank (1 14). As a result of this pressure, the suction pipe (210), which has one end connected to the distribution tank (1 14), takes water from the distribution tank (114) and sends it to the return tank (1 13). The temperature of the water passing through the suction pipe (210) is measured by the heat meter (230).
Since the measured water temperature is lower than the set value, the evaluation unit (243) activates the resistor (220) to heat the suction pipe (210) at the heating area (21 1 ), thereby heating the water passing through the suction pipe (210) and directing it to the return tank (1 13). The heated water from the return tank (1 13) is then directed to the distribution tank (1 14) through the helix (120) and circulation pump (121 ) via the water transfer gaps (115). The water, which is provided in the closed loop as specified, passes through the electric heating unit (200) each time, as indicated above. The water temperature passing through the suction pipe (210) of the electric heating unit (200) is continuously measured by a heat meter (230), and when it reaches the desired level, the evaluation unit (243) deactivates the resistor (220). With this closed-loop water circulation through the heating collector (A) and the underground piping (Y1 ), the space heating process is achieved. If the temperature of the water passing through the suction pipe (210) decreases, the heat meter (230) evaluates the measured temperature value, and the evaluation unit (243) reactivates the resistor (220). This process continues continuously during the operation of the heating collector (A), ensuring the space heating process.
During the initial startup, the resistor (220) consumes continuous energy to bring the room temperature to the desired level. However, once the room temperature reaches the desired level, the frequency of the resistor (220) operation becomes infrequent, resulting in a significantly reduced energy consumption.
The heating collector (A) according to the invention can operate with a preferred voltage of 220 volts, but it can also work with voltages of 110 or 380 volts.
The electric heating unit (200) used in the heating collector (A) can be integrated into the side, bottom, or top sections of the collector unit (100), or it can be produced as an external unit and mounted on the collector unit (100) as required. The operation of the heating collector (A) does not require high-pressure conditions, and there is no need for an external heat source. Therefore, all the drawbacks encountered in the prior art, such as the need for excessive space for installation, the cost of obtaining a heat source, and maintenance/repair costs, are completely eliminated.
