The cooling target includes a cooling target main body part, and a cooling target part which is thermally coupled to the cooling target main body part, and to which the refrigerant is transmitted from the refrigerant sender.

The device and method of the invention are adapted to control temperature and humidity of the air in some defined volume such as a room in a house. The device consists of a quantity of hygroscopic material and means for passing air past or through the material. Direct temperature and humidity control occur when air is conditioned (heated and dried by sorption heating, or cooled and humidified by absorption cooling) and sent inside the room; indirect control is also possible, by affecting the temperature of the walls (the sorption material may occupy channels or spaces within the walls, which are then heated/cooled, indirectly heating/cooling the air in the room by conduction). A fan or blower will allow for forced convection of air in a desired path (e.g from outside the house, over/through the sorption material, and into the house, or in the opposite direction). A second fan and valves allow for more complex operations.

In a method and apparatus for conditioning air for an enclosure, a first ambient airstream is cooled by a cooling coil of a refrigerant cooling system to reduce temperature and humidity, passed through a segment of a rotating desiccant wheel to reduce moisture content and increase temperature, and then supplied to the enclosure. The desiccant wheel is regenerated by a second ambient airstream heated with a condenser coil of the refrigerant system and then passed through a regeneration segment of the desiccant wheel. A bypass plenum allows a third ambient airstream to be selectively heated and cooled independent of the evaporator coil and desiccant wheel in the first plenum. Heated air bypassed from the second ambient airstream or an independent heater can perform the selective heating in the bypass plenum. The airstream in the bypass plenum is then supplied with the air treated in the first plenum to the enclosure.

A method for production of water from air includes cyclically and successively repeating the following two phases: a first phase a), which includes the following steps: a1) taking air from the outside, a2) conveying the air towards an enthalpic exchanger containing an adsorbent material that internally accumulates the moisture that is present in the air, a3) outputting dry air, and a second phase b), which includes the following steps: b1) supplying heat to the enthalpic exchanger by way of a low-temperature heat source, b2) conveying an air flow through the enthalpic exchanger, wherein the air in contact with the enthalpic exchanger is heated and at the same time collects the moisture contained in the adsorbent material, and b3) bringing the heated and humidified air flow to ambient temperature in order to cause the moisture contained therein to condense, thereby obtaining water.

Air conditioning systems and methods for cooling a space that include a chiller, a cooling coil, a heat sink, various water conduits, and a pump. Different modes of operation are used under different conditions and the water is routed differently in different modes. In a first mode, the chiller rejects heat to water returning from the cooling coil, and in a second mode, there are separate loops of chilled and heated water with separate pumps. In a third (economizer) mode of operation, the chiller is off and water from the heat sink is delivered to the cooling coil. Control valves, check valves, or both, are used to direct the flow of water, which are strategically placed in various water conduits.
