摘要： A multi-mode, bi-directional cascade heat pump system, according to some examples, includes at least two chillers each being part of a unidirectional refrigerant circuit. The system includes heat exchangers each of which are dedicated to operate as just a condenser or as just an evaporator, regardless of the system's operating mode. In some modes, a secondary fluid transfers heat between the condenser of one chiller and the evaporator of another chiller before the fluid returns to a secondary fluid source such as, for example, a geothermal borefield or a conventional water source. In some embodiments, fluid is withdrawn from a borefield by way of a pump having a speed that varies to maintain a desired fluid temperature and/or a desired heat transfer rate at the borefield. The heat pump system includes means for minimizing flow through the borefield and for minimizing unnecessary mixing of relatively high and low temperature fluid.

摘要： A vehicle air conditioning system includes a controller that initially controls operation of a compressor to switch between inactive and active states in response to detecting that an operating condition is equal to or surpasses a first operation threshold. The controller determines a first time delay occurring between initiating the switch from one of the inactive and active states to the other of the compressor, and an actual change in the operating condition. The controller subsequently defines a first limit that is offset from the first operation threshold such that the controller controls the operation of the compressor to subsequently switch from the one of inactive and active states to the other in response to detecting that the operating condition is equal to or surpasses the first limit.

摘要： The invention relates to an absorption air conditioner that comprises a desorber (100), a condenser, an evaporator and an absorber, wherein the absorbing fluid may consist of lithium bromide. The method comprises the following steps: calculating the concentration of the absorbing fluid solution at the outlet of the desorber (100); and comparing the calculated concentration with a predetermined critical value and, if the calculated concentration gets closer to the predetermined critical value, increasing the charge loss in the duct (20) connecting the desorber (100) to the condenser, which interrupts the condensation in the condenser and results in a pressure increase in the desorber that stops the desorption and in a concentration increase, the charge loss being on the other hand reduced for resuming the desorption when the calculated concentration deviates from the predetermined critical value. The invention can be used in automobiles and absorption air-conditioners.

摘要： 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.

摘要： A refreshment bar includes one embodiment of a cooling or heating apparatus for food and/or beverage containers. The apparatus maintains a food or beverage container placed on one of the plates at a desired cold or hot temperature relative to the bar surface temperature and ambient temperature. The apparatus includes thermally conductive plates, for example stainless steel disks, positioned in recesses such that the upper surfaces of the plates are coplanar with the top surface of the bar, thereby providing a level surface. A thermal exchanger system is used to cool or heat the plates. The system includes a reservoir containing a thermal element and a thermal transfer fluid. The reservoir is located adjacent the lower surface of the bar top. The plates are thermally coupled to the thermal transfer fluid and thermal element, thereby cooling or heating the plates.

摘要： 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.

摘要： Systems and methods for controlling a thermoelectric cooler (TEC) in an optical transceiver. A TEC system includes a processor that interacts with a power supply and a TEC controller to prevent inrush current. The power supply is switched by the processor and turned on only at a particular time. The power supply has a relatively large time constant such that it ramps slowly to its full value. In the meantime, the processor and TEC controller cause the temperature to ramp to a target value by repeatedly incrementing or decrementing a target value over time and by controlling when the maximum available voltage can be applied to the TEC.
