The invention relates to a beehive according to the preamble of claim 1.

The main costume is the spring and early summer costume. For a profitable beekeeper already in early May strong peoples must be present. The development of a people must be promoted especially in early spring. In addition to the gross activity itself, above all, it is necessary to maintain a tightly limited microclimate in the breast nest.

The nesting parameters are:

-Brutennesttemperatur = 35 ° C at a

relative humidity of = 40%

The energy required to regulate this small climate is considerable and is influenced both by the constructive structure of the apiary and by the outside climate. If this energy expenditure is high, then only a small brood nest can be maintained. Therefore, the minimization of this energy expenditure is an essential prerequisite for a large-scale breeding and thus for an increased development of the people in the spring.

From the breeding nest, with its nesting temperature of 35 ° C, a temperature gradient across the perimeter walls to the outside air is created and thus an energy loss. On the basis of the thermodynamic laws of humid air, cooling changes the air parameters. The dependencies are documented in the Molier-h, x diagram for moist air. Based on the initial state of 3B ° C and a relative humidity of 40%, when it cools below this temperature, the relative humidity increases and at about 19 ° C air temperature reaches its 100% saturation, ie the dew point.

At a further temperature reduction occurs a water vapor excretion. The water vapor content at the above-mentioned dew point is about 14 g / kg dry air. At about 14 ° C only 10g / kg of dry air can be bound.

Does this temperature come with the edge honeycomb and with the inner surfaces de. Bienenwohnungswände in contact, are excreted on these cold objects inevitably 4g of water vapor per 1 kg dry air as condensation.

In the nest of broods (at a constant nesting temperature t = J5 ° C), this water vapor discharge leads to a decrease in the relative humidity of 40% to less than 30%. This condition causes the bees to enter water. In addition to the required performance on the part of the bees, the sometimes unfavorable weather conditions during this activity must be taken into account, which lead to bee losses as well as significant heat losses in the nest.

During the Trachtzeiten occurs at extremely high outside temperatures, a nesting nest temperature increase. Ventilation of the bee's house is achieved by the so-called "Fanning." Also, the entry of water and its distribution on the honeycomb leads to a reduction in temperature.With good costume conditions, highly water-containing nectar is registered.

During treatment, there is an increase in the relative humidity. By "fan" aeration and removal of water vapor can be achieved.

Regardless of the operating mode (top, rear treatment and magazines), beehives with single and / or double-walled enclosing walls are known. In addition, artificial hives are offered in materials with low thermal conductivities. (So we imkern in the Segeberger plastic magazine booty, publishing house Werner Schandau, Kuhholz, 2347 Nottfeld)

Aeration of the bee's dwelling is achieved by placing a hole (top flight hole) in the middle front wall of the beehive or the lid. This hole connects the upper room of the beehive with the outside air (ibid. Page 17, 18)

Further ventilation is achieved by the arrangement of a wire base, (ibid. Page 20-22) A device for heating a hive should reduce the energy loss and thus relieve the regulatory performance, (German Auslezschrift 2626260).

De: constructive construction of the enclosure walls of the beehive - even with the plastic prey - does not prevent the formation of condensation. An elimination of the condensation was sought by aeration.

The means used (top flight hole and wire bottom) lead to increased energy losses, since the top flight hole does not remove the air from the coldest point in the upper room of the bee house.

The wire bottom leads to increased cooling with a poor efficiency of ventilation, since the density difference of the moist air above and below the wire bottom is low. The floor heating only affects the temperature and ignores the influence of the relative humidity - the second main premise of the microclimate.

In addition, the heating is dependent on a foreign energy feed, which is not available on every apiary. The adaptation of the electrical heat to the changing heat demand of the micro-climate is unsatisfactory.

The invention has for its object to reduce the energy performance of the bees to regulate the microclimate and release it for brood care.

This object is achieved in that the enclosing walls of the beehive allow only those heat losses that prevent dew point and thus the formation of condensation. The thermal conductivity of the insulating material used as well as the material and insulating strength determine the structure of the enclosing walls as a function of the unfavorable external climate factors.

The energy-controllable ventilation of the beehive is inventively achieved in that a plurality of ventilation openings are arranged with the same and / or different opening cross sections in the upper, outer interior of Bienenwohnun ^ or the front of the lid, which connect the upper outer space of the beehive with the outside air. In this interior area, the lowest temperature with the lowest enthalpy (Wärmeinha! :) of the indoor air occurs.

This reduces the energy losses.

The strength of the ventilation is determined by the climatic and altitude difference between the vent hole and the ventilation openings and the opening cross-sections. Since the first two factors do not change in a prewardened condition

can be achieved by closing or opening the individual opening cross-sections, the regulation of ventilation.

The discharge of the condensation from the beehive is carried out according to the invention in that the water can drain over the chamfered and / or rounded lower, inner edges of the parting line (inner wall) and on the slope outwardly salaried legs of the parting line.

During the cold season, according to the invention, condensation is carried out by introducing a sheet of heat-conductive material (e.g. The sheet takes in the bee house about the outside temperature. If this temperature is below the dew point, a condensation occurs, which is discharged through the slope to the outside.

The advantages achieved by the invention are, in particular, that the bees relieved of benefits for the regulation of micro-climate and released for other work. These benefits lead to the formation of a larger nest of brood and thus to a good spring development. In addition, improve the hygienic conditions within the hive itself, as a mold is excluded. The success is reflected in an increase in honey yields, especially from the spring and early summer costume. Last but not least, a lower consumption (feed requirement) is to be expected.

An embodiment of the invention is shown in Figures 1 and 2 and is described below:

In Figure 1, the front view of the beehive in training 2 is shown schematically the section through the parting line.

The example represents a magazine loot.

Shown are the front wall 1, the bottom 2, the lid 3, the flight hole 4 and the parting line 5. The ventilation openings 6 in the lid 3 connect the outer, upper interior of the beehive with the outside air.

There is an opening 6 on both sides, but chosen with different opening cross-sections. The openings 6 are closed by plugs. The degree of ventilation is controlled by the partial or total removal of the plugs.

In the flight hole 4, a plate 7 is mounted with a slope to the outside. Part of this sheet 7 enters the magazine loot.
