Description

RATIO INDICATOR SUPPLIED BY ELECTRIC ENERGY
Technical field
The technical solution relates to a ratio indicator supplied by electric energy for distribution of costs of heating of rooms by radiators, consisting of a compact part and a separate temperature sensor.
Background of the invention
At present, many different types of indicators intended for distribution of costs of heating of rooms by radiators are known, based on various principles. For example, these include control of evaporating liquid, control of change of colour of an optical element, etc. There are also electricity-powered indicators operating based on the below-mentioned indication methods.
One-sensor method uses one temperature sensor. It integrates the surface temperature of the radiator at one point of the construction height of the radiator.
Two-sensor method uses two temperature sensors. One sensor integrates the surface, temperature of the radiator; the other sensor integrates the temperature of the heated space, or another temperature, which is in a defined relation to this temperature. Method of middle logarithmic temperature difference with three temperature sensors: i.e. input and output temperature of the heat-carrying substance, and the temperature of the heated space.
A drawback of one-sensor and two-sensor indicators is the large measurement error, caused by a shift of the geometrical place of the middle temperature of the radiator due to operational regulation of radiators in the range 50% to 100% of the construction height of the radiator. Another drawback is the fixed determined beginning of registration for so-called winter and summer operation, which is another source of measurement error, especially in regulated flow rates in individual radiators.
A drawback of indicators using the method of middle logarithmic difference with three indicators is a complicated construction requiring mounting of sensors at the input and output of the heat-carrying substance, which is to the detriment of indicator compactness and increases its price.
A drawback of all electricity-powered and evaporation indicators mounted to radiators is the problematic advance of heat from the heat-carrying substance to the temperature sensor of the indicator or the measuring liquid in case of evaporation indicators. This so-called "C" constant is significantly connected with the indication accuracy. Summary of the invention
The above-mentioned drawbacks are eliminated to a great extent by a ratio indicator supplied by electric energy for determination of payments for heating of rooms by radiators, consisting of a compact part and a separate temperature sensor, pursuant to this technical solution. Its substance is the fact that the compact part is furnished with instruments for its location away from the radiator. The separate temperature sensor is connected to the return pipe in immediate proximity of the radiator output and/or to the radiator in immediate proximity to its output.
The compact part is conveniently furnished with a source of electric power and electric circuits of a microcomputer with a display, which are connected with a switch and an interface. In the convenient version, the compact part is furnished with another temperature sensor. The compact part can be also equipped with a communication element for remote transfer of data.
The devices for location of the compact part away from the radiator allow placing the compact part to a suitable place in the room in such way, that data could be easily read from the device, and at the same time, it did not have disturbing effects from the esthetical point of view. Location of the separate temperature sensor minimizes indication inaccuracies.
The source of electric power guarantees a trouble- free operation of the indicator, and the display with a switch allows easy operation of the indicator. The interface serves for setting of the parameters necessary for exact measurement.
Another temperature sensor increases the measurement accuracy, and at the same time it can serve for a quick determination of temperature in the room. The communication parts for remote data transfer allow measuring of data for determination of payment for heating of rooms by radiators from an area outside the room as well.
A substantial advantage of the ratio indicator pursuant to this technical solution is the new method of acquisition of information serving for proportional distribution of costs of heating of rooms by radiators, which is based on the temperature of the return pipe of the radiator, and on the information of the second sensor of the room temperature, if applicable. It is thus not burdened with errors caused by a shift of the place of middle temperature of the radiator due to regulation of its output.
Detailed description of the invention
Example 1
The ratio indicator consists of a compact part, furnished with clips for placement on a wall of the room, and containing a display, an electronic part with a microcomputer, an energy source and a button switch. The separate temperature sensor is mounted to the return pipe of the radiator in immediate proximity of its output. The operating mode of this indicator allows distinguishing of summer and winter seasons, displays the day of reading, the count on the day of reading derived from the temperature of the return pipe of the radiator, and the current count. Individual readings can be retrieved on the display by repeated pressing of the button switch.
Example 2 The ratio indicator consists of a compact part, which can be placed on a wall of the room, containing a temperature sensor for sensing of the room temperature, a display, an electronic part with microcomputer, a source of energy and a button switch. The separate temperature sensor is located on the return pipe of the radiator in immediate proximity of its output. The operating mode of such indicator allows distinguishing of summer and winter seasons, displays the day of reading, the count on the day of reading derived from the temperature of the return pipe of the radiator, the current count, room temperature, middle temperature of the room as on the day of reading, the current degree of utilization of the output of the radiator. The microcomputer memory contains information on the nominal output of the radiator or the floor area of the heated room, and the code identification of the ratio indicator for its identification. The compact part contains an interface for entry of information regarding the radiator output or the size of the rooms, and a communication part for remote transfer of data, which allows reading without entrance to the flat. Individual data are shown on the display using the button switch. Industrial application
The ratio indicator pursuant to this invention is suitable for determination of proportional payments for heating belonging to individual rooms as a portion of the total amount charged to the accounting unit by the heat supplier.
