Abstract:
PROBLEM TO BE SOLVED: To provide a temperature sensor fixation device capable of fixing stably a temperature sensor in an installation position, by simple structure, and capable of enhancing efficiency of installation work, and an air conditioner equipped therewith. SOLUTION: This temperature sensor fixation device of the present invention includes a sensor holder 30 for storing the temperature sensor 40, and a fixing member 50 inserted into the sensor holder 30 to fix the temperature sensor 40 to the sensor holder 30, and the fixing member 50 includes the first locking part 60 for preventing the fixing member 50 from coming off along an insertion direction, from the sensor holder 30, a close contact part 70 for pressing the temperature sensor 40 onto the sensor holder 30, and the second locking part 80 for preventing the fixing member 50 from coming off along a direction reverse to the insertion direction, from the sensor holder 30, by being deformed elastically when inserted into the sensor holder 30 and by being restored elastically to an original state when projected from the sensor holder 30.

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.

Abstract:
The invention relates to a sensor (110) comprising at least one measuring sensor (124, 140) for detecting at least one measurement variable. The sensor (110) further comprises a sensor body (112) for mounting the measuring sensor (124, 140). The measuring sensor (124, 140) comprises at least one connecting line (212). The sensor (110) has a modular design and comprises a contacting module (210) for the electrical contacting of the measuring sensor (124, 240), said module being configured separately from the sensor body (112). The contacting module (210) comprises at least one connecting element (228) and at least one plug-type contact pin (220), wherein the plug-type contact pin (220) is surrounded in at least one connecting region (232) by the connecting element (228). The plug-type contact pin (220) is electrically connected to the connecting line (212).

Abstract:
Eine Vorrichtung und ein Verfahren durch Erfassung von Raumklimagrössen in einem Gebäuderaum (R) umfasst ein Basisgerät (1) und ein von diesem in einem Abstand (L) angeordnetes Hilfsgerät (2). Vom Basisgerät ausgesendete Schallwellen (A1) werden vom Hilfsgerät (2) detektiert. Über einen Signalisierungskanal (S) wird vom Hilfsgerät (2) der Zeitpunkt des Eintreffens der Schallwellen (A1) an das Basisgerät (1) übermittelt. In einer vorteilhaften Variante der Vorrichtung weist auch das Hilfsgerät (2) einen Schallsender (25) auf. Im Basisgerät (1) sind reflektierte oder vom Hilfsgerät (2) ausgesendete Schallwellen (A2) detektierbar. Aus einer Differenz zwischen richtungsabhängigen Laufzeiten der Schallwellen (A1 und A2) ist eine Luftbewegung (W) im Gebäuderaum (R) erfassbar. Mit Hilfe der Laufzeit der Schallwellen (A1 oder A2) ist auch eine mittlere Temperatur (T) im Gebäuderaum messbar.
