Patent number: 9927160Abstract: An evaporator includes multiple refrigerant tubes, multiple air passages provided between the refrigerant tubes, a cold storage container disposed in the multiple air passages, and a temperature detector. The evaporator further includes a freezing allowable region and a freezing unallowable region that is provided above the freezing allowable region. The cold storage container has a small thickness region and a large thickness region that is positioned above the small thickness region. The large thickness region demarcates a smaller space with the refrigerant tubes than the space demarcated between the small thickness region and the refrigerant tubes. The small thickness region of the cold storage container is positioned within the freezing allowable region, the large thickness region is positioned in the freezing unallowable region, and the temperature detector is disposed in the freezing allowable region.Type: GrantFiled: July 22, 2013Date of Patent: March 27, 2018Assignee: DENSO CORPORATIONInventors: Daisuke Haseba, Toshiya Nagasawa, Eiichi Torigoe, Jun Abei

Patent number: 9863680Abstract: An apparatus includes a refrigerant circuit in which a compressor that compresses a refrigerant, an indoor-side heat exchanger serving as a radiator that exchanges heat between the refrigerant and a heating target, an expansion valve that decompresses the refrigerant by opening-degree adjustment, and an outdoor-side heat exchanger serving as an evaporator that exchanges heat between a heat-exchange target and the refrigerant are connected by pipes. The apparatus includes: an outdoor air temperature sensor that detects a temperature of outdoor air serving as the heat-exchange target; a discharge-side temperature sensor that detects a discharge temperature of the refrigerant discharged by the compressor; and a controller that, when the controller determines that a rotation speed of the compressor is a maximum and the temperature of the heat-exchange target is lower than a preset temperature, controls an opening degree of the expansion valve by using the discharge temperature.Type: GrantFiled: June 20, 2013Date of Patent: January 9, 2018Assignee: Mitsubishi Electric CorporationInventors: Komei Nakajima, Kosuke Tanaka, Hiroaki Makino, Kazuhide Yamamoto

Patent number: 9821630Abstract: A thermal energy storage system of a vehicle is disclosed. The thermal energy storage system includes a refrigerant circuit conveying a refrigerant therethrough. The refrigerant circuit includes an evaporator receives a flow of the refrigerant and a flow of air. The thermal energy storage system also includes a coolant circuit conveying a coolant therethrough. The coolant circuit includes a coolant heat exchanger disposed downstream from the evaporator with respect to a direction of the flow of air through the evaporator and an auxiliary heat exchanger receiving a flow of the coolant. The thermal energy storage system further includes a cold storage device in thermal communication with the coolant circuit and a WCAC in fluid communication with the auxiliary heat exchanger.Type: GrantFiled: September 15, 2014Date of Patent: November 21, 2017Assignee: HANON SYSTEMSInventor: Lakhi Nandlal Goenka

Patent number: 9599382Abstract: An air-conditioning remote controller includes a display section, an operable section, a memory, a transmitter unit, and a processor. The operable section includes a set-temperature increase button and a set-temperature decrease button. In the memory, information designating an upper limit, a lower limit, or both the upper limit and the lower limit as a setting target in setback control is set. The processor makes the display section display a set temperature or temperatures designated by the setting target set in the memory, changes the set temperature or temperatures designated by the setting target on the basis of an operation result of one of or both of the set-temperature increase button and the set-temperature decrease button, and transmits the changed result to the transmitter unit.Type: GrantFiled: August 8, 2012Date of Patent: March 21, 2017Assignee: MITSUBISHI ELECTRIC CORPORATIONInventor: Yoshihiko Higaki
