摘要:
An air conditioner system including an indoor unit and an outdoor unit. The outdoor unit includes a condenser, a temperature sensor, a pressure sensor, and a controller. The controller detects a fault with at least one of the temperature sensor or the pressure sensor and adjusts a speed of the condensing fan according to the pressure identified by the pressure sensor when the pressure sensor is operating normally. The controller adjusts the speed of the condensing fan according to the sensed temperature sensor when the pressure experiences a fault and the temperature sensor is operating normally. The controller controls the speed of the condensing fan according to default values when both the pressure sensor and the temperature sensor experience a fault.

An integrated quiet and energy efficient modes of operation for an air-cooled condenser according to the present disclosure can allow a user to select operation along a continuum that extends from a relatively more efficient mode of operation to a relatively more quiet mode of operation. The user-selected mode allows a user to select a compromise between efficient operation and quiet operation so that a desired operation of a cooling system having the air-cooled condenser is realized. The speed of a fan which induces an airflow across a condenser can be adjusted based on the user-selected operating mode.

A flight control system includes a primary flight display having a hover display which facilitates operations in DVE conditions. The hover display includes a radar altitude display, heading drift symbology and lateral drift symbology which assists pilots in the detection of drift, which is common in DVE situations and to provide the pilot with a salient cue pertinent to the approach to hover and landing.

Method and apparatus for finding the focus of a document. A semantic network includes a plurality of nodes, each representing a concept, and links, connecting the nodes, representing relations between the concepts is used. The method including: providing a list of terms in an input document which match concepts represented by the semantic network, and a frequency value for each matched term indicating the number of times the term appears in the document; mapping each matched term to a referent node or to a plurality of possible referent nodes in the semantic network, and assigning weights to nodes.

Methods, systems, and gateways are disclosed for automatically setting up a redirector of domain name system (DNS) name requests. A DNS setup packet is transmitted to a remote gateway via a tunnel of a virtual private network (VPN). The setup packet comprises a global name of a home network and a private address of a DNS server in the home network. A DNS setup reply packet is received from the remote gateway via the tunnel. The reply packet comprises a global name of another home network and a private address of a DNS server in the other home network. An application level gateway of the DNS server (DNS-ALG) in the home network is configured dependent upon the DNS setup reply packet to redirect DNS name requests for the global name of the other network to the DNS server in the other network. Methods, systems, and gateways are also disclosed for resolving a domain name request in a DNS.

A chiller system includes a refrigerant loop, the refrigerant loop further including a compressor, an air-cooled condenser arrangement and an evaporator arrangement connected in a first closed refrigerant loop. A motor is connected to the compressor to drive the compressor, a drive is connected to the motor to power the motor and a power/control panel controls the refrigerant loop. The power/control panel and the condenser arrangement are connected in a second closed coolant loop. The second closed coolant loop provides cooling to the enclosure and/or components within the enclosure disposed on a chill plate. Condensation is substantially prevented from forming inside the enclosure, despite the enclosure lacking a humidity control device.

A system and method are provided for variable speed operation of a screw compressor to obtain increased capacity and efficiency. The screw compressor is connected to an induction motor driven by a variable speed drive, wherein the screw compressor has a variable output capacity that is dependent on the output speed of the motor. To obtain increased capacity and efficiency, the screw compressor is operated at a speed greater than the screw compressor's rated speed and does not include a slide valve. The maximum operating speed of the screw compressor, which speed is greater than the rated speed, is related to the maximum operating speed of the motor when operated at a voltage and frequency provided by the variable speed drive that is greater than the motor's rated voltage and frequency in a constant flux or constant volts/Hz mode.
