Publication number: 20140325998Abstract: An improved refrigeration and heating system comprising a thermochemical device, and a mobile service cart. The thermochemical device is capable of refrigerating or cooling the ambient air due to an internal chemical process.

However because the theremochemical device is disposed at the center of the cart, the heat which is generated by the cooling process is retained and utilized to provide a separate heating area within the cart. This allows the current system to operate as a closed loop, meaning that the cart and thermochemical device work in conjunction to form a self-sustaining hot and cold storage area with very little maintenance or input from a user.Type: ApplicationFiled: May 2, 2013Publication date: November 6, 2014Inventors: Charles W.

Publication number: 20130284758Abstract: An automated vending machine that can be selectively configured to include one or several temperature zones. A single refrigeration system and universal interior allows easy and economical assembly into a one, two, or three temperature zone machine. Thermal breaks and dividers are used to partition zones, when needed. The basic vending machine cabinet, dispensers, and controls are not changed between configurations. In one aspect, a universal air duct can be used for all three configurations, with minor changes.Type: ApplicationFiled: July 2, 2013Publication date: October 31, 2013Inventors: Francis A.

Publication number: 20130248164Abstract: In a method for controlling an aircraft air conditioning system, a heating or cooling demand of an aircraft region to be air conditioned is determined. A volume flow of recirculation air discharged from the aircraft region to be air conditioned and a volume flow of compressed air into a mixing chamber of the aircraft air conditioning system is controlled such that the heating or cooling demand of the aircraft region to be air conditioned is met, while the volume flow of compressed air into the mixing chamber of the aircraft air conditioning system is minimized.Type: ApplicationFiled: March 19, 2013Publication date: September 26, 2013Applicant: AIRBUS OPERATIONS GMBHInventors: Jürgen KELNHOFER, Dariusz KRAKOWSKI

Publication number: 20130240176Abstract: A heat pump is provided. The heat pump that may include an outdoor heat exchanger, in which a refrigerant may be condensed by being heat-exchanged with outdoor air in a cooling operation, and evaporated by being heat-exchanged with the outdoor air in a heating operation, and an outdoor fan that allows the outdoor air to be moved to the outdoor heat exchanger. The outdoor heat exchanger may include a front-row heat exchange device, through which the outdoor air moved by the outdoor fan may pass, and a rear-row heat exchange device, through which the outdoor air having passed through the front-row heat exchange device may pass; a water-repellent coating layer formed on a surface of the front-row heat exchange device, which the outdoor air contacts; and a hydrophilic coating layer formed on a surface of the rear-row heat exchange device, which the outdoor air contacts.Type: ApplicationFiled: February 8, 2013Publication date: September 19, 2013Inventors: Sangyeul LEE, Hongseong Kim, Juhyok Kim, Hanchoon Lee

Publication number: 20130228323Abstract: A substrate processing apparatus includes: a processing chamber; a support base; an electrostatic chuck; a chiller; a first channel; a second channel; a bypass channel; and a flow rate control valve. The first channel connects the chiller and a coolant entrance of the support base and the second channel connects the chiller and a coolant exit of the support base. The bypass channel branches from a midway of the first channel and is connected to a midway of the second channel. The flow rate control valve controls a flow rate of coolant flowing through the bypass channel.Type: ApplicationFiled: February 21, 2013Publication date: September 5, 2013Applicant: TOKYO ELECTRON LIMITEDInventors: Toshiyuki MAKABE, Taketoshi OKAJO

Publication number: 20130186593Abstract: A split-air arrangement for cooling and dehumidifying air in an indoor conditioned space includes separate first and second courses created from an entering air stream. The first course passes through a desiccant device to remove humidity from the air, the air leaving the desiccant device passing through a first cooling coil to cool the air and the air leaving the first cooling coil entering a supply air plenum. The second course is directed through a first side of a heat exchanger, the air leaving the heat exchanger being heated by a heater element prior to picking up moisture from the desiccant device. Air leaving the desiccant device passes through a second side of the heat exchanger, and subsequently passes through a second cooling coil to cool and dehumidify the air in the second course. Exiting air is mixed with the first course air and returned to the conditioned space in which the process air flow is maximized relative to the regenerative air flow while still permitting effective latent cooling.Type: ApplicationFiled: January 18, 2013Publication date: July 25, 2013Applicant: Synairco, Inc.Inventor: Synairco, Inc.

Patent number: 8459569Abstract: An integrated heating unit operates in a first heating mode, in which the heat of combustion gases is transferred to return air, and a second heat recovery mode, in which the heat of exhaust air is transferred to fresh air. The heating unit of the present invention utilizes the same heat exchanging unit and fans to transfer the heat from the combustion gases to the return air and to transfer heat from the exhaust air to the fresh air. The exhaust air is recovered from a select group of rooms, e.g. kitchens and bathrooms. A secondary heater can also be provided in the integrated unit in the form of a fireplace for providing an alternate or an additional source of the combustion gases.Type: GrantFiled: February 4, 2009Date of Patent: June 11, 2013Assignee: Nu-Air Ventilation Systems Inc.Inventors: Brian Gibbon, Matthew Romanow
