Evaporation device for recording the amount of heat consumed in heating systems

The invention "relates to an evaporation device for detection of consumption heat quantities in heating systems to share the consumption costs.

So far, a Method used that mix the kegs directly in a device instantly with the respective temperature difference multiplied and thus immediately indicates the consumption value in calories.

With the task of distributing the costs incurred in a heating system for allocation to the consumer such a device must be created for each individual heat consumer. This is in the previous one Form economically unsustainable.

Since only one reading per year at the end of the heating season is required for billing a heating system, it is sufficient to calculate the total amount of water and a mean value for to use the temperature difference over the planned billing period. By an evaporation device after the Invention, this object is achieved expediently and economically.

The evaporation device forming the subject of the invention in the detection of consumption heat quantities in heating systems for the distribution of the consumption costs consists in essential in the fact that the same is provided with two mutually thermally insulated pipe section connections and a Has clear U-shaped tube that on both of its Legs is acted upon by the flow or return line.

Due to the two temperature differences given with the flow and return, the heating of the is different closed tube filled with liquid, e.g. butyl glycol. As a result of the resulting differences Vapor pressure, the liquid evaporates according to the size of the temperature difference in the colder leg, '..:, whereby a measurable value arises. At the same temperatures in the flow and return, there is no change in the measured value a.

Other features relate to the design of the evaporation device. They are shown and below described.

An embodiment of the evaporation device according to the invention is shown schematically in the drawing. Show it:

Fig. 1 the internal arrangement of the evaporation device and Fig. 2 the same in housing design, Fig. 3 the same in a detachable connection in a pipe system.

The evaporator Td "consists essentially of two pieces of pipe a, b and a U-shaped curved glass tube c and a two-part housing d with a suitable closure ♦

The U-shaped bent tube c is filled with a liquid suitable for the respective evaporation period and the expected evaporation size, ie the temperature difference, for example in a vacuum. The two legs c ¹ and c ″ are facing downwards. A ^{scale e is attached to leg e 1} for the return, which corresponds to the evaporation characteristic of the liquid or can be made linear by appropriate shaping.

A conventional water meter WZ is built into a line system made up of the flow line V and the return line R, while the evaporator Vd is connected to both lines V and R,

Using such an evaporation device Vd it is possible with several heat consumers, e.g. A breakdown of the total amount of heat consumed for residents of a Y / ohnblock to be broken down into the respective partial amounts of heat consumed. The values obtained from the evaporation device multiplied by the values of the water meter WZ and the result represents a relative value among the consumers here. However, since the evaporation device according to the invention Vd represents an average value of the temperature difference over the billing period, the result obtained is the actual one the amount of heat consumed proportionally. It can therefore be used directly to divide up the total consumption will.
