Patent number: 9746197Abstract: A bathroom air-conditioner includes a refrigerant circuit in which a compressor, a radiator, a decompressing mechanism and a heat absorber are connected with one another through a pipe, a circulating air-course, and a ventilating air-course. In the circulating air-course, the radiator and a circulating fan for circulating the air of the bathroom are placed. In the ventilating air-course, the heat absorber and a ventilating fan for discharging the air from the bathroom to the outside are placed. The heat absorber makes the refrigerant absorb heat from the air of the bathroom, and the radiator makes the refrigerant dissipate heat to the air of the bathroom for heating the bathroom. During the heating of the bathroom, when a temperature of the bathroom becomes higher than a given temperature, a controller reduces an air-blow amount from the ventilating fan.Type: GrantFiled: January 29, 2008Date of Patent: August 29, 2017Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Yoshimasa Katsumi, Yoshihiro Nishizuru, Kazuhiro Saitou, Mitunori Matubara, Masafumi Tsubouchi, Yuuji Sugata, Hiroshi Tsuihiji

Patent number: 8539788Abstract: An ventilating and air conditioning apparatus includes a circulating fan for sucking air from a sucking port open to a first indoor space and blowing the air through a blowout port into the first indoor space, a ventilating fan for sucking air from an exhausting port open to a second indoor space and evacuating the air to the outdoors for ventilation, and a refrigerant circuit formed of a compressor for compressing a refrigerant, a first heat exchanger for exchanging heat of air blown into the first indoor space by the circulating fan with the refrigerant, an expanding mechanism for expanding the refrigerant, and a second heat exchanger for exchanging heat of air blown into the second indoor space by the ventilating fan with the refrigerant. The compressor, first heat exchanger, expanding mechanism, and second heat exchanger are coupled together with pipes for the refrigerant to circulate therethrough in this order.Type: GrantFiled: July 10, 2007Date of Patent: September 24, 2013Assignee: Panasonic CorporationInventors: Yoshimasa Katsumi, Hiroyuki Kondou, Mitunori Matubara, Masafumi Tsubouchi

Publication number: 20110100043Abstract: The ventilating air-conditioning system includes an air supply fan; an exhaust fan; a compressor; a first heat exchanger heat-exchanging between outdoor air sent from the air supply fan and a refrigerant; an expansion mechanism; a second heat exchanger heat-exchanging between air in a sanitary space sent by the exhaust fan and a refrigerant; and a refrigerant circuit piped so that a refrigerant circulates in order of the compressor, first heat exchanger, expansion mechanism, and second heat exchanger, or in order of the compressor, second heat exchanger, expansion mechanism, and first heat exchanger. The system heats or cools an indoor space while ventilating a sanitary space by transferring heat between the first heat exchanger and second heat exchanger through a refrigerant.Type: ApplicationFiled: August 28, 2008Publication date: May 5, 2011Applicant: Panasonic CorporationInventors: Mitunori Matubara, Yuuji Sugata, Masafumi Tsubouchi, Kei Takeshita, Yoshimasa Katsumi, Yoshihiro Nishizuru, Kazuhiro Saitou
