The desiccant channels are configured to channel desiccant from the desiccant inlet to the desiccant outlet in at least one of a counter-flow or cross-flow direction with respect to the direction of the air stream. | 03-24-2016 |
20160084577 | TEMPERATURE-CONTROLLED PORTABLE COOLING UNITS - Portage storage containers including controlled evaporative cooling systems are described herein. In some embodiments, a portable container including an integral controlled evaporative cooling system includes: a storage region, an evaporative region adjacent to the storage region, a desiccant region adjacent to the outside of the container, and an insulation region positioned between the evaporative region and the desiccant region. A vapor conduit with an attached vapor control unit has a first end within the evaporative region and a second end within the desiccant region. In some embodiments, the controlled evaporative cooling systems are positioned in a radial configuration within the portable container. | 03-24-2016 |
20160091214 | Nested Heat Transfer System - A novel nested heat transfer system comprises a plurality of chained enhanced entrochemical cells with nested structures. Each enhanced entrochemical cell includes a first chamber containing desiccant, or a higher concentration solution, and a second chamber containing refrigerant, or a lower concentration solution. Preferably, the first chamber and the second chamber are connected by a conduit. Furthermore, a smaller chamber in an enhanced entrochemical cell is encapsulated by a larger chamber in an adjacent enhanced entrochemical cell, thus forming a nested structure between the two enhanced entrochemical cells. A chain of enhanced entrochemical cells with a plurality of such nested structures is conveniently modular and scalable. For the novel nested heat transfer system, the total systemic thermal gradient is the sum of individual thermal gradients and capacity of individual enhanced entrochemical cells. This design provides highly-versatile and high-capacity refrigeration and thermal transfer systems, while exhibiting an elegant design simplicity. | 03-31-2016 |
20160146479 | DEHUMIDIFICATION DEVICE AND DEHUMIDIFICATION SYSTEM - First and second adsorption heat exchangers are provided for first and second heat exchange chambers, respectively, and each interchangeably function as an evaporator or a condenser. If the first adsorption heat exchanger functions as an evaporator in the first heat exchange chamber, a first adsorption block is arranged at a position downstream of the first adsorption heat exchanger. If the second adsorption heat exchanger functions as an evaporator in the second heat exchange chamber, a second adsorption block is arranged at a position downstream of the second adsorption heat exchanger. | 05-26-2016 |
20160146513 | DESICCANT COOLING SYSTEM - A desiccant cooling system includes a desiccant cooler including a desiccant cooling path through which air introduced from the outside passes, a desiccant dehumidifier on the desiccant cooling path to pass through air and remove humidity of the air, and a water cooling portion cooling cooling water by using the low-humidity air that has passed through the desiccant dehumidifier; and a vapor compression cooling device including a water cooled condenser disposed to be cooled by the cooling water cooled by the water cooling portion so as to condense a refrigerant flowing inside the water cooled condenser, wherein the refrigerant is circulated in the water cooled condenser. | 05-26-2016 |
20160187011 | METHODS AND SYSTEMS FOR MINI-SPLIT LIQUID DESICCANT AIR CONDITIONING - A split liquid desiccant air conditioning system is disclosed for treating an air stream flowing into a space in a building. The split liquid desiccant air-conditioning system is switchable between operating in a warm weather operation mode wherein the system provides cooling and dehumidification, and a cold weather operation mode wherein the system provides heating and humidification, as well as into a mode wherein the system provides heated, dehumidified air to a space. | 06-30-2016 |
