  • Patent number: 11162739
    Abstract: An air-conditioning apparatus using a heat pipe is provided, where the state of the outside air is compared with the state of set supply air. The heat exchange and mixed supply of outside air and ventilation air are effectively performed by changing the passage of the ventilation air and the outside air through the selective opening/shutting of dampers, cooling the outside air through latent heat by spraying mist, and by controlling supply air in a set state through the cooling and humidification of the supply air. Accordingly, energy efficiency can be improved and the energy necessary for the air-conditioning apparatus can be reduced using the evaporation latent heat of water. Furthermore, operation costs can be reduced and financial gains can be obtained because an efficient operation can be performed in response to the state of a measured outside air.

  • Patent number: 8726539
    Abstract: A gas heater with specialized controls allows an operator to deploy a single device to heat and to dry when extracting moisture from a structure. The heater has a fan in a blow thru arrangement ahead of a burner. The burner uses either natural gas or liquefied petroleum gas. The heater has air flow, fan motor, temperature, and ignition controls and sensors. The heater delivers high temperature air to the structure that hastens evaporation as the heated air absorbs great concentrations of water vapor. Then the moisture laden heated air exits the building as the heater draws in fresh air, ducts it into a structure, and pressurizes the structure. This moisture laden air then leaks from the building through select windows using the energy imparted from the fan and then exhausts the moisture to the atmosphere, drying the structure.

  • Publication number: 20140027523
    Abstract: A transportation trailer having a moving floor including a plurality of reciprocating slats for loading/unloading materials into the trailer. The trailer includes a system for warming the moving floor when the materials transported in the trailer freeze on the slats in cold weather. Using the pre-existing hollow structure of the slats, a stream of hot fluid or a hot fluid pipe is run inside the slats for thawing the frozen materials for unloading the trailer. The hot fluid may be provided from a hot fluid source on board of the trailer, for thawing the frozen materials while the trailer is on its way to the unloading site, or may be provided separately at the unloading site.

  • Patent number: 8544454
    Abstract: The invention relates to a heat exchanger (or a motor vehicle, comprising a first flow path (1) with a number of flow conduits (6) for conducting a fluid to be cooled, a deflection region (13), situated downstream of the first flow path (1) and a second flow path (2), situated downstream ol the deflection region (13). According to the invention, the flow conduits (6) of the first flow path (1) continue in the deflection region (13) and the second (low path (2) as continuous separate flow conduits (6). The invention also relates to a flow conduit (41, 41?, 61, 61?, 71, 71?, 81, 81?, 91, 91?) for a heat exchanger (30,40) for exchanging heat between a first fluid (31) and a second fluid (33). The aim of the invention is to guarantee an improved transfer of heat with a simultaneous acceptable pressure drop, whilst reducing the blocking risk.

  • Patent number: 8534346
    Abstract: A modular, water-to-air heat exchanger with flexible tubes is adjustable in length to conform to different size cooling coils and thus provides an inexpensive, retro-fittable run-around heat recovery for pre-existing air handling systems. The heat exchanger comprises multiple heat exchange tubes formed of flexible material in a shape that permits them to be lengthened or shortened by simply moving the headers toward or away from each other. Preferably, the tubes are formed of a flexible, non-resilient material such as copper, and are shaped in a serpentine or helical manner. In this way, the tubes can be drawn out to elongate the heat exchanger or compressed to shorten it, depending on the dimension of the cooling coil in the air handler. One convenient way to control the length of the flexible tubes is to support the headers on one or more adjustment bars, each having a threaded adjustment mechanism.

  • Patent number: 8505614
    Abstract: The present invention relates to a measure for minimizing an undesired passage of fluid from a first sector (1) to a second sector (2) separated by a non-fluid-tight separation (3), wherein a first pressure (P1-1) prevails in the first sector (1) and a lower second pressure (P2-1) than the first pressure (P1-1) prevails in the second sector (2). An intermediate chamber (4) which separates the two sectors (1, 2) from one another is arranged at the separation (3). A conveyor mechanism (5) is further provided which is designed to convey fluid from the intermediate chamber (4) to the first sector (1).

  • Patent number: 8453720
    Abstract: A condensing type dryer uses a heat exchanger in which condensed water can be smoothly discharged through a water-discharging slot formed in a rear end portion of a rear cover of the heat exchanger. The water-discharging slot prevents an air flowing resistance which can be caused by condensed water pooling at the rear end portion of the rear cover. Also, leakage-preventing walls enhance the heat exchanging function by ensuring a uniform flow of cold external air through the heat changer. The leakage-preventing walls prevent external air from leaking around the lateral edges of the heat exchanger.
