Abstract:
A method is described for a medium-long term meteorological forecast starting from the meteorological parameters of a large-scale geographical area (SG) having a predefined extent. The method comprises the following phases: decomposing the meteorological parameters of the large-scale geographical area (SG) into a base component and a part which arises as a variation on a regional scale (SR), wherein the variation on a regional scale (SR) is defined as the difference between the large-scale geographical area (SG) and the base area; determining the temperature close to the surface of the base area, starting from the parameters available on the large- scale geographical area (SG), using an empirical- statistical model (statistical down-scaling); determining the deviation in the meteorological parameters on a regional scale (SR), starting from the parameters available on the large-scale geographical area (SG), using a dynamic numerical model (dynamic down-scaling); effecting the combination (ensemble down-scaling), through an applicative model, of the empirical-statistical model (statistical down-scaling) and the dynamic numerical model (dynamic down-scaling) to obtain the medium and long-term temperature forecast.
Abstract:
Hourly CO 2 concentration, amount of solar radiation, and plant distribution information are calculated through observation from predetermined satellites. A concentration of CO 2 absorbed by plant-chlorophyll per each time unit is calculated. By adding up the CO 2 concentration on the earth and the concentration of CO 2 absorbed by the plant-chlorophyll, a CO 2 concentration obtained provided that no plant-chlorophyll exist is calculated for a certain period. Thereafter, a mean concentration of CO 2 that is absorbed according to changes in the distribution of plant-chlorophyll is calculated on the basis of a monthly mean solar radiation amount and plant-chlorophyll distribution information. By subtracting the CO 2 concentration, which is a mean, from the total CO 2 concentration, a CO 2 concentration, which is a normal, is calculated.
Abstract:
A cover for the bulb of a thermal expansion valve is comprised of two halves of an insulative body that are wrapped around the bulb and associated outlet types in clamshell fashion to encapsulate the combination. Internal and external flaps are hingedly connected along their longitudinal edges to permit access for inspection purposes, and the external flap is secured to the internal flap by Velcro. A tongue structure on the outer surface of the body fits into grooves on the inner surface of the outer flap to seal the cover against the entry of moisture. The two halves are secured in place at their ends by way of bands.

The temperature sensor 3 is fixed such that the soldered portion 8 is soldered to a surface of the printed board 2, the covered wire 3a is inserted through the hole 5 and engaged with the cut 7 to be fixed, and the temperature detection portion 3b is located near an inner surface of the upper case 1 a.
Abstract:
Es werden ein Verfahren und eine Vorrichtung zur Detektion der Kennlinie f (ϑ) eines Messfühlers (2) für zeitlich veränderliche Temperaturmesswerte, die in Heizungs- oder Klimaanlagen oder deren Regelungen verwendet werden, vorgeschlagen, bei denen eine Messwertfolge des Messfühlers (2) und eine Messwertfolge eines Referenzmessfühlers (4) mit bekannter Kennlinie erfasst und die einzelnen Messwerte des Messfühlers (2) in Relation zu den Messwerten des Referenzmessfühlers (4) gesetzt werden. Um auch in nichtstationären Zuständen eine Kennliniendetektion zu ermöglichen wird vorgeschlagen, dass bei einer nichtstationären Messwertfolge ein möglicher Zeitversatz (Δ T R , Rohsignale ,Δ T R,Filt ) zwischen einer Messwertfolge des Messfühlers (2) und einer Messwertfolge des Referenzmessfühler (4) ermittelt und korrigiert wird.

Abstract:
A system and method for evaluating parameters for a refrigeration system having a variable speed compressor is provided. A compressor is connected to a condenser and an evaporator. A condenser sensor and an evaporator sensor are provided. An inverter drive modulates a frequency of electric power delivered to the compressor to modulate a speed of the compressor. A monitor module receives compressor power data and compressor speed data from the inverter drive, determines a measured condenser temperature based on the condenser signal, determines a measured evaporator temperature based on the evaporator signal, calculates a first derived condenser temperature based on the compressor power data and the compressor speed data, calculates a second derived condenser temperature based on the measured evaporator temperature, the compressor power data and the compressor speed data, and compares the measured condenser temperature with the first and second derived condenser temperatures to determine whether any of the measured condenser temperature and the first and second derived condenser temperatures are inaccurate.
