Publication number: 20200393170Abstract: A chiller plant is disclosed. The chiller plant includes a chiller circuit including a chiller, a first process fluid circuit, and a first heat exchanger. The chiller is configured to provide a first process fluid at a first temperature. The chiller plant also includes an air handling circuit including a plurality of ice storage tanks and an air handling unit. The chiller plant further includes a terminal cooling circuit including a plurality of terminals, the terminal cooling circuit providing a second process fluid to the plurality of terminals at a second temperature that is different from the first temperature. The terminal cooling circuit is fluidly separate from, but thermally communicates with, the chiller circuit via the first heat exchanger.Type: ApplicationFiled: August 31, 2020Publication date: December 17, 2020Inventors: John Arthur Murphy, Susanna S. Hanson, Kevin P. Bradley, Anthony Wayne Bruno

Patent number: 10495358Abstract: A multi-mode, bi-directional cascade heat pump system, according to some examples, includes at least two chillers each being part of a unidirectional refrigerant circuit. The system includes heat exchangers each of which are dedicated to operate as just a condenser or as just an evaporator, regardless of the system's operating mode. In some modes, a secondary fluid transfers heat between the condenser of one chiller and the evaporator of another chiller before the fluid returns to a secondary fluid source such as, for example, a geothermal borefield or a conventional water source. In some embodiments, fluid is withdrawn from a borefield by way of a pump having a speed that varies to maintain a desired fluid temperature and/or a desired heat transfer rate at the borefield. The heat pump system includes means for minimizing flow through the borefield and for minimizing unnecessary mixing of relatively high and low temperature fluid.Type: GrantFiled: August 22, 2016Date of Patent: December 3, 2019Assignee: TRANE INTERNATIONAL INC.Inventors: Lee R. Cline, Michael C. A. Schwedler, Susanna S. Hanson, Brian J. Fiegen
