摘要： A valve for regulating fluid flow and associated method of use. The valve includes a stepper motor (16), a first valve portion (54) having an inlet port (46) for receiving fluid into the valve, a second valve portion (56) having an outlet port (48) for dispensing fluid from the valve, a third valve portion (50) located between the first valve portion (54) and the second valve portion (56), a first member (12) that is rotatable and operatively attached to the stepper motor (16), and a second member, having a first portion (9) and a second portion (11), which engages the first member (12) for linear movement of the second member between a first position and a second position when the first member is rotated by the stepper motor (16) to block fluid flow when the second member is located in the first position and allow fluid flow when the second member is located in the second position.

摘要： A wide input voltage range relay drive circuit allowing a more than 2:1 input voltage variation is provided. The circuit utilizes a scaled and rectified bulk voltage to drive the relay coil. As the monitored bulk voltage increases beyond the relay coil rated voltage, the circuit pulse width multiplexes this bulk voltage to protect the relay coil. The bulk voltage switching does not begin, however, until the relay energizes. To reduce the power dissipation during the PWM switching, of the relay coil, a power dissipating switch is included and held on during the PWM switching events. To further increase relay life, the circuit controls the energizing of the relay coil to actuate the contacts of the relay at or near a zero cross of the power switched thereby.

摘要： To provide a solenoid valve allowing to feed different evaporators either individually or simultaneously there is proposed a multi-state solenoid valve using a core element (10) having a coil (12) for magnetisation of the core element. Further, a member (14) with at least one permanent magnet (16) is arranged with respect to the core element (10) such that a relative movement between a member (14) with the permanent magnet (16) and the core element (10) is possible. In addition, the solenoid valve comprises stopper means (18, 20) for limiting the relative movement of the core element (10) and the member (14) between a first and a second limit stop position. According to the present invention the core element (10) only can be energized to move the element (14) with the at least one permanent magnet (16).

摘要： A controller (1) for controlling the temperature in a food compartment of a refrigerator switches on the compressor (6) of the refrigerator when the actual temperature exceeds a cut-in temperature threshold (T on ) and switches off the compressor when the evaporator temperature falls below a cut-out temperature threshold (T off ). The controller (1) detects a thermal dispersion of the refrigerator for compensating the influence of the ambient temperature on the temperature inside the refrigerator. The cut-in temperature (T on ) and/or the cut-out temperature (T off ) are adjusted in accordance with a thermal dispersion ratio based on a ratio of a rate of fall of evaporator temperature when the compressor is on, to a rate of rise of temperature when said compressor is off.

摘要： The present invention relates to a controller and a method of controlling a defrost operation in a refrigerator. The duration of a refrigeration period is determined by the amount of time needed for defrosting the evaporator of the refrigerator. If the defrost duration deviates from a target defrost duration, the next refrigeration period is adjusted accordingly, to maintain the actual defrost duration close to the target defrost duration. According to the invention, the target defrost duration is determined based on the detection of a thermal dispersion of the refrigerator. A high ambient temperature results in a reduced target defrost duration while in low ambient temperature conditions the target defrost duration is larger. Preferably, the thermal dispersion is detected based on the ratio of a rate of fall of evaporator temperature when the compressor is on to a rate of rise of evaporator temperature when the compressor is off, on a continuous basis during the refrigeration period.

摘要： The present invention relates to a refrigerator appliance combining a fridge compartment and a freezer compartment. In order to allow an energy efficient operation, the refrigerator appliance comprises a solenoid valve (1) for controlling the flow of cooling liquid in the refrigeration circuit, the solenoid valve (1) having at least three different operating states (S1,S2,S3). Due to the plurality of different operating states, it is possible to achieve an independent operation of each of the evaporators (5a,5b) of the combi-refrigerator appliance, or a simultaneous operation of the evaporators, in accordance with the actual cooling demand in each of the compartments. Also, due to the plurality of operating states it is possible to provide one operating state in which the outlet of the compressor (2) is blocked when the compressor (2) is off, to sustain the pressure in the condensor during periods of compressor inactivity. In this way a cooling overshoot at the end of period of compressor acivity can be shifted to the beginning of each period of compressor activity, this resulting in increased energy efficiency.

摘要： In a dangerous conditions sensing alarm system which includes a plurality of interconnected dangerous condition sensing units (Unit A, Unit B 70, Unit C 71, Unit D 72, Unit E 73), such as smoke detectors, of the general type in which each unit responds to an apparently sensed dangerous condition by issuing an audible alarm and also by transmitting, from an input/output terminal (20 - I/O), a signal to the other units (received as an external alarm signal at corresponding input/output terminals of the other units) so that an alarm condition sensed by any one of the units results in alarms being sounded by all the units, a unit initiating an alarm (which may be false) is marked by an alarm origination circuit. The alarm origination circuit includes a visual indicator such as an LED (61) and a latch device such as an SCR 51 connected in-circuit such that, when the SCR is turned 'on', the LED is activated and remains lit until the SCR is turned 'off'. The SCR is turned 'on' by a signal developed from the audio frequency drive to the unit annunciator (22) unless this action has been earlier inhibited by an electronic switch (52) which, just before the local alarm is sounded, places a virtual ground on the SCR gate (75). The electronic switch is activated by an external alarm signal more quickly than the local unit's audio frequency drive is established. Thus, an external alarm signal will not cause the LED to light at the local unit.
