Publication number: 20230296270Abstract: A method for air conditioning including installing an air conditioning unit at a desired location. The air conditioning unit includes a housing that has air supply inlets and exhaust air outlets. The housing encloses a mode control unit that switches a zone coil associated with a zone from a cooling mode to a heating mode by switching from a cooling medium to a heating medium flowing through the zone coil. The zone coil receives the heating or cooling medium and conditions incoming air from a supply fan to be exhausted in a zone associated with the zone coil. A variable refrigerant flow cooling/heating unit provides a cooling medium or a heating medium at varying rates to control a temperature of a zone.Type: ApplicationFiled: January 16, 2023Publication date: September 21, 2023Applicant: MJC, Inc.Inventors: Edward H. Metzger, Joel John Williams, Charles Thomas Couch, Kelly Gene Sprayberry

Patent number: 10094578Abstract: Apparatus and methods provide for a dual pass air flow configuration in an air conditioning system to improve efficiency and performance of the air conditioning system. An air conditioning device includes a pre-conditioned air passage chamber separated from a post-conditioned air passage chamber by an impermeable partition. A coil system separates the pre-conditioned air passage chamber and the post-conditioned air passage chamber from a partially-conditioned air passage chamber. The coil system is configured to receive air from the pre-conditioned air passage chamber and to condition the air passing through the coil system into the partially-conditioned air passage chamber. The coil system is also configured to receive the air from the partially-conditioned air and further condition the air as it passes through the coil system into the post-conditioned air passage chamber.Type: GrantFiled: February 12, 2015Date of Patent: October 9, 2018Assignee: MJC, Inc.Inventor: Edward H.

Patent number: 9576507Abstract: A placard holder has a clamp member with an enlarged head and an elongated stem. The head defines a narrow slot such that a card containing visually perceptible or machine readable information can be mounted to the head by a friction fit of an edge of the card inserted into the slot. The clamp member attaches to a supporting article such as a display stand by extending the stem through a hole of a thin wall of the support and placing a lock washer over the stem opposite the head. The lock washer is forced along the stem end to compress the wall between it and the head. Compression is maintained by prongs of the lock washer that engage radially protruding teeth disposed along the elongated stem. Paper or plastic placards such as business cards, credit cards, place cards, gift cards can be placed in the placard holder for display.Type: GrantFiled: July 24, 2015Date of Patent: February 21, 2017Assignee: PURR-FECTION BY MJC, INC.Inventors: Craig Stanley Helmholz, Martin Joseph Castro
