Patent number: 9062890Abstract: An energy recovery heat exchanger (100) includes a housing (102). The housing has a first flowpath (144) from a first inlet (104) to a first outlet (106). The housing has a second flowpath (146) from a second inlet (108) to a second outlet (110). Either of two cores may be in an operative position in the housing. Each core has a number of first passageways having open first and second ends and closed first and second sides. Each core has a number of second such passageways interspersed with the first passageways. The ends of the second passageways are aligned with the sides of the first passageways and vice versa. A number of heat transfer member sections separate adjacent ones of the first and second passageways. An actuator is coupled to the carrier to shift the cores between first and second conditions. In the first condition, the first core (20) is in the operative position and the second core (220) is not. In the second condition, the second core is in the operative position and the first core is not.Type: GrantFiled: July 1, 2009Date of Patent: June 23, 2015Assignee: CARRIER CORPORATIONInventors: Jeffrey T. Benoit, Gregory M. Dobbs, Norberto O. Lemcoff

Patent number: 8795588Abstract: A contaminant removal system is disclosed for selectively removing contaminants from a fluid stream. The contaminant removal system has a catalytic reactor of the type that is susceptible to deactivating agents, and is configured to remove contaminants from a fluid stream. The contaminant removal system has a first adsorbent device positioned upstream, with respect to the fluid stream direction, of the catalytic reactor, that is configured to chemically bind with and remove the deactivating agents from the fluid stream. The contaminant removal system can have a second adsorbent device positioned downstream, with respect to the fluid stream direction, of the catalytic reactor. The second adsorbent device is configured to remove undesirable byproducts that may be generated when the catalytic reactor removes contaminants from the fluid stream.Type: GrantFiled: May 31, 2007Date of Patent: August 5, 2014Assignee: Carrier CorporationInventors: Zissis A.

Publication number: 20120027657Abstract: Ultraviolet photocatalytic oxidation (UV-PCO) air purification system includes controller that coordinates operation of photocatalytic reactor that removes volatile organic compounds from air and a regeneration mode that removes contaminants adsorbed in UV-PCO system. Controller coordinates operation of the regeneration mode and photocatalytic reactor so that when air purification system is turned on, the regeneration mode begins to operate before photocatalytic reactor is activated. The initial operation of the regeneration mode allows contaminants that have adsorbed in UV-PCO system to be removed before controller initiates a normal operation mode by activating photocatalytic reactor to cleanse the air.Type: ApplicationFiled: February 1, 2008Publication date: February 2, 2012Applicant: CARRIER CORPORATIONInventors: Norberto O.

Publication number: 20100254868Abstract: A system and method (60) for a purifying a fluid (such as air or water) containing contaminants includes removing the contaminants from the fluid (70) using a capturing device, such as an adsorbent and/or a particle filter. The contaminants may include volatile organic compounds (VOCs) and microorganisms. The method (60) further includes generating ozone molecules using an ozone generating device (62). An ozone decomposition device is used to decompose at least a portion of the ozone molecules into oxygen and oxygen radicals (68). The captured contaminants (VOCs and microorganisms) react with the oxygen radicals and the ozone molecules to denature the contaminants (72), rendering them less harmful than the original contaminants in the fluid. In some cases, the contaminants may be reduced to carbon dioxide and water.Type: ApplicationFiled: June 22, 2007Publication date: October 7, 2010Applicant: CARRIER CORPORATIONInventors: Timothy N.

Patent number: 7740810Abstract: An air treatment system includes a filter and heating element, a plasma device, and a photocatalyst and UV light that cooperate to purify an air stream flowing through the air treatment system and protect the photocatalyst from passivating effects of certain contaminants. The air treatment system operates in two different modes. In the first mode, the air treatment system primarily draws air from and returns air to a space, and the heating element and plasma device are selectively shut off. In the second mode, the air treatment system regenerates the filter using the heating element to selectively heat the filter and release adsorbed contaminants. The plasma device is selectively turned on and chemically transforms the released contaminants into solid contaminant products. The solid contaminant products are deposited on a biased electrode of the plasma device. The UV light is turned off to ensure that the photocatalyst is inoperable during the release and transformation of the contaminants.Type: GrantFiled: December 14, 2004Date of Patent: June 22, 2010Assignee: Carrier CorporationInventors: Stephen O Hay, Susan D.
