    Keksinnöllä tarkoitetaan menettelyjä ja laitteita kustannustehokkaaseen kostudenhallinta tiloissa joissa ei ole jatkuvia lämitystarpeita. Se tapahtuu väliaikaisissa ljmitysvaiheissa, jotka minimoidaan siihen mitä tarvitaan että suhteellinen kostus pysyy hyväksyttävän alhaisena. Lämpötila tilaan sisällä ja ulkopuolella mitataan jatkuvasti, jos suitsatilla sisälläpuolella on alempi kuin ulkopuolella, ljmitys on päällä. Voit myös mitata suhteellinen kostus RH tilassa ja ottaa sopivan ylilämpötilan uudelleen vaiheissa, jolloin RH olisi muuten liian korkea. Laitteet on tarkoitettu menettelyjen toteuttamiseen joko analogisella tai digitalilla tekniikalla. Niihin kuuluvat ulkolämpötila (21) ja suitsötila (22) ja RH (23) tilan sisällä, ja lisäksi differentialiaalvahvistin (24, 25), kynnysyksikkö (26) ja vertailulaitteet (27) sekä vaikuttavat säätimet (28) jotka toimitta lämity.

    专利说明:

    The present invention relates to methods and devices for cost-effective moisture control in locations that do not need to be kept constantly heated, which are preferably located in climate zones with an annual average temperature below + 15 ° C and where the weather during at least some part of the year varies between stages of low temperatures and mild weather periods with high humidity. Without action, such conditions can lead to moisture precipitation and moisture accumulation, which in turn can lead to mold formation and rot. To avoid this, there are two main methods: air dehumidification and / or heating. For air dehumidification, there are some alternative methods and equipment - based on these available. What they have in common is that condensation water is formed during dehumidification, which in practice makes them unusable at temperatures below 0 ° C. With regard to heating, it is generally known that it has a drying effect, and it works at all current temperatures. In e.g. holiday homes, which are also used occasionally during the winter and are therefore equipped with thermostat-controlled heating devices, are the common method, as in their simplest form it means that the heat is left on even when the house is not in use. A disadvantage that limits its occurrence is the high heating cost. A common way to reduce this is to set the thermostats or preferably a thermostat common to the house for a lower temperature while the house is not inhabited. The choice of this reference temperature must then be a balance between, on the one hand, a low heating cost and, on the other hand, the risk of moisture precipitation under certain weather conditions. A temperature that is often recommended is + 10 ° C. Even in this case, the cost is experienced - annoyingly high. A possible alternative method which, however, has come to very limited use is hygrostat-controlled heating which is in progress in the stages when relative humidity RH, i.e. the ratio between actual and possible dissolved water volume in the air exceeds a predetermined value. Because it will happen with - considerable delay due to the fact that the humid air must first penetrate. via existing air exchange to the measuring point indoors, during that time - i.a. the outer walls and their thermal insulation to be exposed to N unrepaired harmful moisture precipitation and moisture accumulation.
    The object of the present invention is to minimize the heating cost. The method is the same as the one first described above (page 1 line 13), o but instead of a fixed preset reference temperature, a © variable is used which is continuously selected as low as possible with regard to the currently prevailing humidity risk. To determine this, according to the Lr invention, the temperature of the air outside the locality is used as a reference, 0 40 | amply increased by a small temperature margin, which can be fixed and 0 predetermined to typically a few degrees, or be controlled by some other 2 factor t. ex. RH inside the locality. This utilizes the fact that N cooler than required ambient air is required for moisture precipitation. It is now seen to N that such cold surfaces are not provided in the site or its outer walls.
    For a good result, the measurement outside the site should refer to the temperature of the air as such, i.e. be unaffected by disturbing factors such as heating from sunlight. Likewise, the measurement inside the site should refer to the surface of a wall or other solid object that has been chosen to be representative of a surface where moisture loss can primarily be expected. This means e.g. measurement at such a distance from the heat source that direct heating via radiation from it is avoided or where incident sunshine can provide local heating. Such a location means that the temperature measurement is delayed and thus also the end of the heating stages. It provides a temporary extra heating which i.a. penetrates the outer walls and there further counteracts moisture precipitation, which can be especially important when changing from cold to mildly humid weather. To avoid corrosion and mold, RH should not exceed 50 - 70%. | In a locality without heating or other climate-affecting measures, RH is mainly determined by the external air that gradually penetrates into the room via ventilation or penetration, and that air can have RH up to 100%. In a further development of the method of the invention, the comparison of indoor and outdoor temperature is combined with a measurement of RH inside the locality and a comparison of this with a predetermined reference level. Heating then takes place either directly when one of the comparisons indicates the exceeded reference value or indirectly by allowing RH to control the margin (page 1, line 40) that, when necessary, a balanced overtemperature is maintained. By this combination one gains that temperature comparison procedure- | its rapid reactivity compensates for the slowness of the moisture comparison process at e.g. change from cold to mild weather as well as that the latter procedure counteracts the risk that the dew point, i.e. RH = 100% is achieved indoors in the event of sudden changes to cold weather. : Devices for carrying out the methods according to the invention comprise measuring sensors for temperature inside and outside the locality, possibly also - sensors for moisture, and a signal processing unit to which these sensors are connected, and which in turn controls a heating system, which may be a part of the device or consists of an existing facility on the site. The sensors can be made with known technology, e.g. thermistors for the temperature sensors or be capacitive of the polymer type for the humidity sensor and may include electrical; Ronics for converting the measured quantity into a suitable signal form e.g. analog - such as voltage or current level, or as digital. For the sensor outside, N also includes devices to ensure that the temperature of only the air N is measured e.g. fastening devices that minimize heat conduction from the surface where it is <mounted and placement of the measuring sensor itself with substantially free space <Q 40 all around. The signal processing unit can be of e.g. digital or analog 2 type. | in the digital case, it may consist of a microcomputer programmed to perform the methods of the invention. | in the analog case it can = be built up with amplifiers, threshold units which can consist of diodes and> comparators (comparators). S 45 - The methods will be described in more detail here and variants within the scope of the invention are shown by means of algorithms where S N
    A1 Ti = Measured temperature inside the site. Tu = Measured temperature outside the site, preferably outdoors Tr = Reference temperature (eg according to page 1 line 23) Th = Temperature hysteresis, with determined value for control technical stability.

RHm = Measured relative humidity inside the locality RHh = Highest accepted relative humidity inside the locality RHu = Limit below which RH is considered to have no practical significance. K = Conversion constant Definition according to A7 below. As a starting point, thermostatically controlled heating is used here as a reference (page 1 line 19) whose function can be described according to algorithms A2 or A3 below: A2 - (Heating on} OM {Ti <Tr) (Heating off) OM ([Ti> Tr + Th} alternatively (Heat off) if (Ti - Th> Tr 3 Furthermore, any hysteresis that may occur is assumed to be understood, which is marked in case A2 by the following simplified spelling: A3 (Heat) IF {Ti <Tr} The basic procedure according to the invention is described in an analogous manner: A4 (Heat) IF {Ti <Tu} With the addition of a temperature margin obtained: A5 - (Heat) IF ((Ti <Tu + Tm} AND {Tm> 0}} OTHERWISE {Ti <Tu! alternatively :: (Heat) IF {{Ti-Tm <Tu) AND {Tm> 0)} OTHERWISE ([Ti <Tu) - alternatively: N (Heat) OM ((Ti-Tu <Tm} AND {Tm> 0 )} OTHERWISE ABOUT {Ti-Tu <0}
