In an electromotive compressor of an air-conditioner for use in an automobile, an interior space of a container of a compressor is divided into a space including a compression mechanism portion and an electric motor portion, and an oil storage space, wherein an oil passage is provided in a lower portion while a partition having a gas passage in an upper portion thereof, and a gas emission pipe is provided in one of the two (2) spaces at the oil storage portion side, being divided by the partition plate, while an oil supply pipe in the other, thereby making an opening of the oil supply pipe dipped within the lubricating oil even when a car declines.

Air-conditioner for use in an automobile

An ice thermal storage type air conditioner includes an outdoor unit,equipped with a compressor,and an outdoor heat exchanger,, an indoor unit,equipped with an indoor heat exchanger,and an expansion valve,, and an ice thermal storage tank,. The ice thermal storage tank is equipped with a heat exchanger exchanger used as a condenser when the accumulated heat is used. The heat exchanger has a pipe-shaped heat transfer tube,and a plate-shaped fin,installed to the heat transfer tube. The fin is installed vertically, and a plurality of rows of the heat transfer tubes and the fins are arranged.

Ice thermal storage type air conditioner and ice thermal storage tank

An ice thermal storage type air-conditioner and an ice thermal storage tank, in which unused portions in the ice thermal storage tank is reduced to enhance an ice filling rate in the ice thermal storage tank or to prevent excessive icing from damaging a heat transfer unit. An ice thermal storage type air-conditioner in which heat exchangers are installed in the ice thermal storage tank 1, the heat exchangers having a heightwise size extending from a bottom of the ice thermal storage tank 1 to near a top of a container, and comprising a plurality of flat-shaped plate-type heat transfer units 14 arranged therein in layered manner in a thicknesswise direction
