摘要： A superheat sensor (1) for sensing superheat of a fluid flowing in a flow channel (3) is disclosed. The sensor (1) comprises a flexible wall defining an interface between an inner cavity (5) having a charge fluid (6) arranged therein and the flow channel (3). The flexible wall is arranged in the flow channel (3) in thermal contact with the fluid flowing therein, and the flexible wall is adapted to conduct heat between the flow channel (3) and the inner cavity (5). Thereby the temperature of the charge fluid (6) adapts to the temperature of the fluid flowing in the flow channel (3), and the pressure in the inner cavity (5) is determined by this temperature. A first wall part (7, 14) and a second wall part (9, 16) are arranged at a variable distance from each other, said distance being defined by a differential pressure between the pressure of the charge fluid (6) and the pressure of the fluid flowing in the flow channel (3), i.e. depending on the pressure and the temperature of the fluid flowing in the flow channel (3), and thereby the superheat of the fluid. A distance sensor, e.g. comprising a permanent magnet (8) and a Hall sensor (10), measures the distance between the wall parts, and the superheat is calculated from the measured distance. The sensor (1) is suitable for use in a refrigeration system. The sensor (1) is mechanically simple and capable of determining the superheat by measuring only one parameter.

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.

摘要： An air conditioner performs a refrigerant quantity judging operation to judge the refrigerant quantity in a refrigerant circuit, and includes a heat source unit, utilization units, expansion mechanisms, a first refrigerant gas pipe, a second refrigerant gas pipe, a refrigerant liquid pipe, switching mechanisms, temperature detecting means, and a controller. The heat source unit includes a compression means and a heat source side heat exchanger. The first refrigerant gas pipe is connected to the discharge side of the compression means. The switching mechanism can switch between a first state and a second state. The temperature detecting means are mounted on the first refrigerant gas pipe, and configured to detect a refrigerant temperature on the first refrigerant gas pipe side and output a refrigerant temperature detection value. The controller corrects the refrigerant quantity judged by a refrigerant quantity judging operation based on the refrigerant temperature detection value.

摘要： A method for selectively cooling one or more heat-generating electronic components in an enclosure. Air is passed through an enclosure that houses one or more heat-generating components. Heated air is separated into at least first and second parallel airstreams within the enclosure. The first airstream is passed through a first heat exchanger in thermal contact with a first side of a thermoelectric cooling module. The second airstream is passed through a second heat exchanger in thermal contact with a second side of the thermoelectric cooling module. A voltage is applied to the thermoelectric cooling module to cool the first side and heat the second side of the thermoelectric cooling module. A temperature at a location in the enclosure in sensed and the voltage applied to the thermoelectric cooling module is varied in response to the sensed temperature.

摘要： Embodiments include systems and methods for selectively cooling heat-generating electronic components in an enclosure. According to one embodiment, an enclosure houses a plurality of heat-generating electronic components. Air enters the enclosure at the front and is exhausted at the rear. After passing through one or more upstream components, air diverges into at least first and second airstreams within the enclosure. The first airstream is re-cooled by a cooling system having a thermoelectric cooling module. The thermoelectric cooling module is configured such that a first side is cooled and a second side is heated in response to an applied voltage. A voltage regulator may govern the voltage in response to one or more temperatures sensed within the rack system.
