    Abstract: An air conditioning system includes a dehumidifier, a regenerator, and a refrigeration system. The dehumidifier removes water from a first airflow using a liquid desiccant. The regenerator transfers water from the dilute desiccant into a second airflow. The refrigeration system can be selectively used to provide heat to the desiccant in the regenerator to more effectively remove the water from the dilute desiccant. An external heat source can also be used to heat the desiccant in the regenerator to more effectively remove the water from the dilute desiccant. The refrigeration system and the external heat source can each be used separately to heat the desiccant, or the desiccant can be heated by both heat sources simultaneously.

  • Patent number: 8159170
    Abstract: When cooling operation or dehumidifying operation is started, a blower fan for an evaporator and an exhaust fan for a condenser are driven at an initial rotational number. A compressor is driven at a fixed rotational number. Due to load variation, an operating current supplied from a power source is changed. When the operating current exceeds a reference value, the rotational number of the blower fan is gradually reduced. When an endothermic quantity by the evaporator decreases, a temperature of a gas refrigerant flowing through the evaporator is lowered. Since the load applied on the compressor is reduced, the operating current decreases. In this way, when the compressor is loaded, the operating current increased, however, by controlling operation of the fans as described above, it is possible to prevent that the power source is shut off due to overcurrent and operation is stopped.

A housing defines a perimeter of the cell with an inlet and outlet for air passing therethrough. Water outlet nozzles within the housing are preferably supported upon bars which orient the nozzles facing in a direction counter to flow of air through the housing. Each nozzle is coupled to a separate stage with multiple stages of nozzles coupled to separate valves. A controller opens or closes different valves. The controller measures ambient humidity and temperature conditions as well as air flow rates to calculate the amount of water to be added to the air and then opens appropriate numbers of stages of valves so that an appropriate number of nozzles spray water into the air to saturate the air. Flow rate control is thus provided without pressure variations, for optimal nozzle performance.

The coating consists of a porous technical ceramic material, such as a mineral wool.

  • Publication number: 20100275629
    Abstract: A thermally activated air conditioning system is disclosed that both dries and chills the air being conditioned. Drying is by a liquid desiccant subsystem, and chilling is by an absorption chilling subsystem. A very high COP (1.25) is obtainable owing to the use of reject heat from the absorption subsystem to power the desiccant subsystem. The overall system (or cycle) is powered by relatively low temperature input heat (e.g. 245° F.). That heat can be obtained from flat plate or evacuated tube solar collectors, or other sources. The low driving temperature is made possible by the disclosed integration between the two subcycles.

  • Patent number: 7802442
    Abstract: A distribution apparatus, system and method for thermal control whereby a plate of a manifold assembly has predetermined surface features positioned on specific locations on a surface thereof for enhancing the cooling capabilities of the assembly. The predetermined surface features of the plate delay a velocity decay of a fluid impinging the surface of the plate, while also increase the surface area of the plate exposed to the impinging liquid, which in turn, maximize both the reliability and thermal performance of the overall thermal system at a given maximum operating pressure.

  • Patent number: 7775064
    Abstract: The invention relates to an evaporative cooler having two medium circuits which are thermally coupled to one another by a number of heat-conducting vertical walls. These walls and the heat-conducting fins arranged thereon are provided with a hydrophilic, water-buffering covering layer, for example made from Portland cement. A humidification unit for moistening the covering layer is added to the dew point cooler. According to the invention, the humidification unit comprises a releasable cover which forms part of the casing of the dew point cooler and bears at least one sprinkler or nozzle for distributing water over the covering layer.

  • Patent number: 7765827
    Abstract: A multi-stage hybrid evaporative cooling system is described as having a direct evaporative cooling subsystem and an indirect evaporative cooling subsystem having one of a horizontal and a vertical set of heat exchanger channels. The multi-stage hybrid evaporative cooling system with a horizontal set of heat exchanger channels has a portion of the horizontal heat exchanger channels partially extended into a next stage of the multi-stage system. The multi-stage hybrid evaporative cooling system with the vertical set of heat exchanger channels includes a first set of vertical set of heat exchanger channels spanning a substantial vertical height of the stage of the hybrid evaporative cooling system, and a second set spanning approximately half the height of the stage. The multi-stage hybrid evaporative cooling system further includes a refrigeration system for lowering the temperature of the indirect evaporative cooling subsystem air without affecting its pressure flow.

  • Patent number: 7730736
    Abstract: A refrigerant circuit (40) is provided with two adsorption heat exchangers (56, 57) in addition to an outdoor heat exchanger (54) and an indoor heat exchanger (55). The indoor heat exchanger (55) and the two adsorption heat exchangers (56, 57) are disposed in an indoor unit (11), while the outdoor heat exchanger (54) is disposed in an outdoor unit (12). In the adsorption heat exchanger (56, 57) serving as an evaporator, moisture in the air is adsorbed by the adsorbent. In the adsorption heat exchanger (56, 57) serving as a condenser, moisture is desorbed from the adsorbent and then applied to the air. Then, the air dehumidified or humidified by the adsorption heat exchanger (56, 57) is supplied to a room to cope with latent heat load in the room. On the other hand, in the indoor heat exchanger (55), air is cooled or heated. Then, the air cooled or heated by the indoor heat exchanger (55) is supplied to the room to cope with sensible heat load in the room.

  • Patent number: 7698906
    Abstract: An evaporative chiller cooling water to below ambient wet bulb temperature. Sub-wet bulb chilling is achieved by pre-cooling incoming air upstream of the saturator. The incoming air is ambient air at ambient air temperature that is cooled using the coolness of the lower temperature outgoing air exiting the saturator. The pre-cooling lowers the temperature of the incoming air and lowers its wet bulb temperature below that of ambient air. The saturator water is chilled to below the ambient wet bulb temperature. The air in the saturator flows across the water as it gravity drips or flows from the top to the bottom of the saturator. The pre-cooled air flows across the saturator with the coolest air directed across the bottom of the saturator where the coldest water is flowing and with the hottest air directed across the top where the hottest water is flowing to provide gradient chilling.

  • Patent number: 7694432
    Abstract: The present invention concerns a method and apparatus for dehumidifying, drying or the like of different materials. The invention is developed primarily for dehumidification of sewage sludge (7), but it may be utilized for many different materials including foodstuffs as crispbread and pasta. The sludge (7) or other material is dehumidified or dried in a chamber (1) by means of thermal radiation. The thermal radiation is given by means of one or more elements (2) for thermal radiation. The thermal radiation is concentrated to one or more distinct wavelength ranges at which water has peaks for absorption of radiation energy. Air is circulated in the chamber (1), to take up moisture evaporated from the material.
