The system can thus be operated to collect water regardless of whether cooling of the building interior is required at a particular point in time. Use of the same cooling element in each mode provides and use of return air from the building to mix with incoming fresh air and cool the heat dissipating element of the cooling system make for efficient operation. Controls of the system are operable to change a mixture ratio of the fresh atmospheric air and circulating return air.

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.

  • Patent number: 8707719
    Abstract: An air conditioner includes a refrigerant circuit, a switching valve, an outdoor fan and a controller. The refrigerant circuit sequentially circulates refrigerant through a compressor, an indoor heat exchanger, a decompression mechanism and an outdoor heat exchanger during a heating operation. The switching valve is connected to the refrigerant circuit to switch a flow direction of the refrigerant discharged from the compressor. The controller executes a defrosting operation control in which the outdoor fan is deactivated and the switching valve directs refrigerant discharged from the compressor towards the outdoor heat exchanger during a defrosting operation. The controller further maintains the switching valve so refrigerant discharged from the compressor is directed towards the outdoor heat exchanger and executes a fan defrosting operation control in which the outdoor fan is rotated for a predetermined period of time after completion of the defrosting operation when a predetermined condition is satisfied.

  • Patent number: 8701427
    Abstract: A method for controlling a vehicle HVAC system to automatically defog a windshield glass and to prevent fogging or condensation of the windshield glass. In-cabin air temperature and relative humidity are measured and used to determine a dewpoint. Further, ambient or outside temperature is measured. If windshield wipers are being used or if the cabin air temperature is less than a predetermined temperature, the ambient air temperature value is used as a glass temperature, otherwise the glass temperature is determined from the ambient air temperature and vehicle speed. A fog margin, which is a measure of the likelihood of fog formation, is based upon the difference between dewpoint and the windshield glass temperature. The fog margin is used to control the HVAC system to anticipate and respond to potential fogging conditions.

  • Patent number: 8695365
    Abstract: An apparatus for managing operation of refrigerating machines controls defrosting of evaporators of refrigeration cycles. Each of the refrigeration cycles uses a compressor, a condenser, a decompressor, and the evaporator, and is formed for a corresponding one of cooling/heating devices installed in a single store. The apparatus obtains a total estimated power consumption in a case of a pull-down operation using power consumptions necessary for the pull-down operation performed for the cooling/heating devices after defrosting is performed and using a power consumption of the store that includes at least the power consumptions of the refrigeration cycles and that is estimated for each of predetermined time periods. The apparatus changes defrosting start times or defrosting end times of the cooling/heating devices so that the total estimated power consumption does not exceed an upper limit value of a power consumption set in advance by the store.

  • Publication number: 20130340458
    Abstract: Water for data center uses is generated from the ambient air by a water generator that cools air below its dew point, thereby causing the water in such air to precipitate out. The water generator is powered by renewable energy sources that provide a sufficient amount of energy over an extended period of time, despite temporary interruptions. Heated air from the data center is exhausted so as to absorb moisture from the ambient air, with such heated air being capable of holding a greater amount of moisture, and is then directed through the water generator, thereby enabling the water generator to generate a greater amount of water. The level of water available is monitored and the water generator utilizes on-demand power sources to generate a greater amount of water so as to avoid emptying water storage units.

  • Patent number: 8561417
    Abstract: A fluid-sensing switch system that can monitor pre-established threshold fluid levels in the primary drain pan inside an air conditioning unit or other condensate-producing unit, and also in a secondary drain pan positioned under the unit. Once the threaded plug of a sensing probe is connected to the unit's weep hole, it positions a center sensor providing a first power potential through a false-trigger-reducing resilient piece in a position to wait for rising fluid capable of breaching a weep hole dam. A substantially circular sensor is also present provides the second power potential needed for signal generation. A signal-generating member connected to both sensors is electrically connected to the unit to shut it off, and/or activate a pump that removes fluid from the secondary drain pan. The signal-generating member provides the redundant safety alarm capability, when mounted on a secondary drain pan. Anti-microbial elements are optional, but preferred.
