  • Patent number: 11339980
    Abstract: A dehumidifier has a main body and a main tank. The main body has a secondary tank, a pump, and a retracting mechanism. A conduit portion of the retracting mechanism is mounted through and into the main tank, so the pump can draw water from the secondary tank and into the main tank. The main tank is mounted beside the main body and can be drawn upward to separate from the main body. The main tank has a first inclined surface. When the main tank is moved upward, the first inclined surface pushes the retracting mechanism, so the conduit portion retracts and is moved away from a moving path of the main tank when the main tank is being drawn upward. With the main tank mounted beside the main body, the main tank facilitates water pouring.

  • Patent number: 11320172
    Abstract: An air conditioner shut-off system includes an overflow conduit that is coupled, at one end, to the drainage system of an air handler unit of the air conditioner system. The opposite end of the overflow conduit is positioned over an overflow container, which is suspended by a harness at the lower end of the harness. The upper end of the harness being operably coupled to the breaker throw of the main breaker, which is provided on or proximate to the air handler unit. If the drainage system becomes obstructed, water will flow into the overflow container through the conduit, and eventually the mass of the water accumulated in the overflow container will produce enough force acting on the breaker throw through the harness to flip the breaker throw to the OFF position and shut off the air conditioner system.

  • Patent number: 8875528
    Abstract: A test chamber that is capable of operating in a mode where the temperature of the chamber is efficiently cooled without removing a substantial amount of moisture from the air. In one aspect, the test chamber includes a structure defining a work space having air, and a temperature control system (e.g., a refrigeration system having a compressor, a condenser, and an evaporator valve). The temperature control system includes a heat exchanger (e.g., an evaporator) positioned to communicate with the air in the work space, a source of cold fluid (e.g., a compressed, condensed, and throttled refrigerant) coupled to the heat exchanger, a source of hot fluid (e.g., compressed refrigerant gas) coupled to the heat exchanger, and a controller for controlling a mixture of cold fluid and hot fluid entering the heat exchanger (e.g., by adjusting a cold fluid valve and/or a hot fluid valve).

  • Patent number: 8840729
    Abstract: An air conditioning drain cleaning system with an automated blow-out cycle to clean out an evaporator pan drain pipe. The system has a pneumatic valve assembly, a controller, a float level switch assembly and a plurality of air lines in a manifold for actuating the pneumatic valve assembly and blowing out the drain pipe. The controller directs the system to initiate or repeat a blow-out cycle until the drain pipe is clear. The pneumatic valve assembly bisects the drain pipe to selectively close the pipe for cleaning with a pair of high pressure air shots, one shot toward each pipe end to dislodge a clog. The float level switch assembly signals the controller if the condensate level in the drain pan drops. If the condensate level does not drop, the controller initiates a further blow-out cycle at increased pressures until the line is clear.

  • Publication number: 20140260360
    Abstract: A refrigerated merchandiser includes a sensor coupled to a case adjacent an air inlet. The sensor is in communication with a portion of a refrigerated airflow passing through the air inlet to sense a temperature of the airflow and to generate a signal indicative of an air return temperature. The merchandiser also includes a controller in communication with the sensor to receive the signal indicative of the air return temperature, the controller further in communication with a conductive film on a door and programmed to initiate a clearing interval to clear condensation from the door in response to the signal indicative of the air return temperature reaching a first predetermined temperature threshold.

    Abstract: An automatic climate controller device may be configured to perform operations including identifying, by an automatic climate controller device, an operating zone of the climate control system according to at least two input factors; identifying a discharge temperature of the climate control system; determining, based on the operating zone and the discharge temperature, whether to perform at least one override action to override a climate control system setting to reduce the possibility of evaporator core icing; and adjusting an evaporator set point according to the at least one override action to reduce the discharge temperature. The input factors may include evaporator temperature and cabin relative humidity. The actions may include to increase blower speed and to increase use of recirculated air.

  • Patent number: 8794018
    Abstract: A system for preventing icing in a conduit, as can occur in an aircraft's air conditioning system, includes at least one sensor for acquiring mechanical oscillations of the conduits, an electronic evaluation unit and an electronic control unit. The sensor is connected to the electronic evaluation unit, which knows characteristics relating to the oscillation behavior of the conduit and is equipped to compare the measured conduit oscillations with these characteristics, and through correlation to interpret them as conduit icing, and in the case of conduit icing to emit a signal to the control unit. If the operation-associated oscillations are inadequate, oscillations can be generated or amplified through an actuator. With this system an icing state within the conduit can be detected without the use of sensors located in the interior cross section of the conduit, which itself serves as a sensitive element.

    Abstract: A conduit (51) for a condensate removal pump is disclosed comprising a tubular member (47) having a profiled rim (53, 54) at a distal end, profiled such that only a portion of the rim lies in a plane located at the extreme distal end of the tubular member perpendicular to the axis of the tubular. A resilient membrane (52) which has a slit extends across the interior of the tubular member and is arranged to open, to allow water to pass, when water is drawn through the conduit. A combined sensor and suction tube assembly (50) is also disclosed comprising a tube (55), a self heating thermistor (56) coupled to the tube, and a relay means (69) to relay an operational parameter of the self heating thermistor, indicative of the presence of water, to a condensate removal pump. The combined sensor and suction tube assembly is sized to fit within a pipe having an inner diameter of 20 mm.

  • Patent number: 8783049
    Abstract: A cooling system for a data center in which equipment racks are disposed has a cooling unit and a controller coupled to the cooling unit. The cooling system includes temperature sensors at or near the cooling unit's air return inlet, at or near the cooling unit's air supply outlet, and at or near the equipment racks air inlet(s). The controller measures these temperatures. A relative humidity sensor is located at or near the air return inlet of the cooling unit. The relative humidity where the relative humidity sensor is located is measured by the controller using the relative humidity sensor. The controller calculates the dew point temperature from the temperature sensor and relative humidity. Using this dew point, which is essentially constant throughout the space being conditioned, and the temperatures from the other locations, the controller then calculates the relative humidity at each location.

    Abstract: An in-vehicle absorption heat pump device comprises a regenerator; an in-vehicle heat source heating absorbent in the regenerator; a gas-liquid separator; a condenser condensing gas phase separated from the absorbent; an evaporator evaporating a condensate to form vapor; an absorber for bringing the relatively concentrated absorbent in liquid phase in contact with the gas phase to cause the absorbent to absorb the gas phase and be relatively diluted; an absorbent circulation source circulating the absorbent; a bypass passage connecting a liquid-phase storing portion of the gas-liquid separator and the regenerator while bypassing the absorber; and a bypass transfer source in the bypass passage returning the absorbent in the gas-liquid separator to the regenerator. To dilute absorbent in the absorber, a diluent passage allows the condenser and the absorber to communicate and the condensate in the condenser to be supplied to the absorber through the diluent passage by a dilution element.
