Description

A utility model relates to devices for changing heat transfer.

A solution is known for heat exchangers and heat transfer devices of OVENTROP company, Germany, comprising a pump, a housing, a thermoelectric heater, a thermostat, connecting elements, mounting clamps, a filling plug, and a safety valve (1).

A mini-module for underfloor water heating systems of small areas is proposed, comprising a pump, module housing, thermoelectric heater, thermostat, connecting elements, mounting clamps, filling plug, safety valve. The mini-module is characterized in that it is made with a built-in heater and an autonomous circulation pump, a temperature sensor is built into the thermoelectric heater, and has a remote thermostat.

The mini-module is shown in the drawings, where FIG. 1 is a circuit diagram, and FIG. 2 is a general view of the module.

The figures show: 1 - circulation pump, 2 - module housing, 3 - thermoelectric heater, 4 - thermostat, 5 - connecting elements, 6 - mounting clamps, 7 - filling plug, 8 - safety valve.

The heat carrier stream (mainly water) coming from the circuits of the underfloor heating system circulating using the built-in circulation pump 1 enters the module 2 housing and is heated using the built-in thermoelectric heater 3, after which it is directed back to the circuits of the underfloor heating system. The heat carrier of the water floor heating circuits transfers heat to the heating panel, and the heating panel, in turn, transfers heat to the air of the premises served.

The heating medium is controlled by a temperature sensor built into the heating element 3, and the on and off control of the heating element is controlled by a remote thermostat 4, designed to set the required temperature mode.

Plug 7 is designed to fill the system with water, as well as to control the presence of fluid in the module.

The safety valve 8 with a pressure limit of 4 bar is designed to protect the system from overpressure.

The mini-module is an autonomous, compact, economical, monoblock unit.

- Autonomy

It is used for autonomous (independent of external heat sources) water floor heating of small areas, preparation and maintenance of the required temperature of the heat carrier (mainly water), distribution of heat carrier between the circuits of the floor water heating system, circulation of the heat carrier in the circuits and safe operation.

- preparation of the required temperature of the coolant is carried out due to direct electrical heating of the coolant by the built-in thermoelectric heater 3 of low power (from 100 to 750 W) by turning it on and off;

- maintaining the set temperature of the coolant for all the circuits of the underfloor heating system connected to the module is carried out by setting the temperature on the thermostat 4 connected to the thermoelectric heater 3. The thermostat is installed next to the module and is included in it, the temperature level control sensor is built into the module together with a thermoelectric heater. The thermostat with the help of a sensor monitors the set temperature and gives a command to turn on (when the temperature drops from the set) or turn off (when the set temperature is reached) the thermoelectric heater;

- the module automatically supports the set parameters of the coolant depending on fluctuations in the temperature of the return coolant, as well as the temperature of the floor surface and / or air served by the room module;

- the coolant can be distributed between the circuits of the underfloor heating system. Each circuit is connected to the module at two points: one at the supply output, the other at the return. For each circuit to be connected, a connector is installed at the connection point. To connect more pipelines of smaller diameter, a distribution manifold (not shown) can be connected. In total, up to three circuits made by pipelines of small diameter can be connected;

- the module has its own built-in circulation pump 1, providing circulation of the coolant in the underfloor heating system with the module.

- the built-in safety valve 8, with a response limit of 4 bar, ensures the safe operation of the module. A special thermoelectric heater is able to work for a long time without liquid, without burning or harming the surrounding equipment and objects.

- compact

The module for small floor water heating systems is small and can be placed in small niches, cabinets, under bathrooms, sinks and sinks.

- Profitability

The design of the module and the principle of its operation allows:

- save the working time of designing organizations. There is no need for separate selection of elements for their hydraulic linkage, as well as connecting the system to various sources of heat supply in order to heat the coolant. In this design, all functions are combined into a single unit.

- save working time of installation organizations. All nodes and mechanisms are assembled in one place, it is enough to install the module and connect the floor heating system circuit and power supply to it.

- reduce the connected electrical load when using floor heating systems in small areas. Floor heating systems using an electric heating cable are known, in which electric energy is converted due to the high resistance of the conductor (electric cable) to heat, then thermal energy is transferred to the heating surface. T.O. for the effective operation of the cable system requires a plug-in electrical load at the rate of 100-150 watts per 1 square. meter of heated surface (for rooms). In the inventive module, an electric heater performs heating directly of the coolant, and the coolant, in turn, gives off heat to the heating surface. T.O. with a built-in heater with a power of 350 W of the unit, it is possible to heat an area of up to 12 sq.m (comfort mode, specific load 30 W / sq. m), while for the same area when using a cable heating system, a connected electrical load of 1200-1800 W will be required.

- Monoblock

Placement of all mechanisms (heating, control, distribution, circulation, protection) assembled (built-in, connected, tested) in the factory allows:

- independently mount a system of water floor heating without resorting to the services of installation, design and operating organizations;

- to achieve the reduction of unauthorized connection of underfloor heating systems to the central heating and hot water supply systems;

- to simplify the maintenance of the water heating system, to reduce the risks of failures of the heating system, and in the event of failures to minimize the consequences and timing of their elimination, all units are concentrated in one place, and the volume of coolant in the entire system is 0.5-2.5 liters.

Preferred version: mini-module for underfloor heating systems for small areas consists of a circulation pump 1, housing 2, a heating element with an integrated temperature sensor 3, a control thermostat 4, docking connectors 5, mounting clamps 6, filling plug 7 and a safety valve 8.

The module for underfloor heating systems of small areas is characterized by the fact that the temperature setting of the supplied coolant is low (up to 45 ° C).

The module is characterized by the fact that it works practically without pressure in the system and does not require the installation of expansion tanks.

The module is characterized by the fact that it is designed to operate floor heating systems in an autonomous year-round mode with low power consumption.

The module is characterized by the fact that it has a built-in low-power heater that can work for a long time without liquid, without burning and without harming the surrounding equipment and objects.

The module is characterized by the fact that it is safe even with increasing pressure in the system; excess pressure is released when the level is 4 bar. The module is characterized by the fact that it can service systems made by pipelines of small diameter (from 12 mm and less).

The module is characterized in that it is capable of supporting the heating system and the room in frost protection mode.

The module differs from standard water heating systems in that it has its own built-in heater and an autonomous circulation pump.

The module differs from standard cable electric heating systems in that it requires a significantly lower plug-in electrical load.
