Patent number: 12173912Abstract: A ventilation air conditioning structure including a room that has a floor portion to a fourth wall portion, a first wall portion to be a building outer wall in which an air supply opening is formed in a vicinity of a third wall portion, and an air exhaust opening that is formed in a vicinity of the fourth wall portion. The ventilation air conditioning structure also includes an air conditioner that is disposed inside the room and where at least one of air sending openings of a room interior unit is capable of sending air in a direction of a second wall portion, and an external-air conditioner that is disposed outside the room. The external-air conditioner includes heat exchangers that are incorporated in a refrigerant circuit of the air conditioner via a branched pipe that is branched from a refrigerant piping and a casing that houses the heat exchangers.Type: GrantFiled: May 11, 2020Date of Patent: December 24, 2024Assignee: Eco Factory Co., Ltd.Inventor: Takanobu Murakami

Patent number: 11703235Abstract: An external-air conditioning apparatus and a ventilation system are provided, the external-air conditioning apparatus includes a fin tube type heat exchanger and a housing that stores this heat exchanger. The housing includes a base body that serves as a back side of the apparatus body and a cover body that serves as a front side of the apparatus body, and the base body and the cover body are dividable and detachable in structure. The base body has a base portion, a partitioning portion, a connecting pipe portion, a heat-exchanger-holding structure portion, and a water receiving portion. The cover body is a structure in which a front wall portion and a three-side peripheral wall portion are formed integrally with each other, and a part in which the peripheral wall portion is not formed is an inlet for external air.Type: GrantFiled: October 16, 2018Date of Patent: July 18, 2023Assignee: Eco Factory Co., Ltd.Inventor: Takanobu Murakami
