At the time of dehumidifying operation, a motor-operated expansion valve is controlled so that evaporation of a refrigerant will be completed in an auxiliary indoor heat exchanger which constitutes an indoor heat exchanger together with a main indoor heat exchanger. A louver is operated to form an air passage through which air discharged from the outlet port of an indoor unit flows to the inlet port. Owing to the formation of such an air passage from the outlet to the inlet port of the indoor unit, dehumidification is performed with outlet air kept from reaching the living space in the room.

Air conditioning apparatus having dehumidifying operation function

The present invention includes fins that are juxtaposed at narrow intervals. One side of the fins serves as an upstream side, and the other side thereof serves as a downstream side. Heat exchange air passes through the fins. A bent portion is provided at a substantially middle portion of the fins in the longitudinal direction of the fins, and the fins are bent at the bent portion at a predetermined angle. Heat exchange pipes are provided to penetrate the fins and are arranged in an upstream-side front row and a downstream-side rear row. U-bend portions are provided to connect end portions of adjacent heat exchange pipes. Passageways for guiding a heat exchange medium are formed by the heat exchange pipes and U-bend portions. The passageways introduce the heat exchange medium from a flow introducing unit provided on the upstream side, guide the heat exchange medium from the upstream side to the downstream side at the bent portion, guide the heat exchange medium again to the upstream side, and discharge the heat exchange medium from a flow discharging unit provided on the downstream side.

Heat exchanger having in fins flow passageways constituted by heat

An air conditioner includes a case assembly having a front portion, a rear portion, and a top portion in which a suction aperture is formed, a heat exchanger, located in the case assembly, for performing heat exchange with respect to an indoor air introduced through the suction aperture. A blower is located in the case assembly, for supplying the indoor air introduced through the suction aperture into the heat exchanger and for expelling the indoor air from the case assembly after the heat exchange by the heat exchanger. And, open-close means are provided for the top portion of the case assembly, for selectively opening or closing the suction aperture.

Air conditioner

A portable air conditioning apparatus includes a refrigerating circuit comprising a variable capacity compressor and a condenser cooled by water fed from a water tank and a flow of air generated by a fan device, an inverter for outputting a variable driving frequency to the compressor, and a control section for controlling the frequency of the inverter in response to an air conditioning load in a defined space. The control section has a frequency control function by which the driving frequency of the inverter is forcibly decreased irrespective of the air conditioning load to reduce the consumption of water at the condenser when an amount of water is detected to be below a prescribed value in the water tank.

Portable type air conditioning apparatus

An air conditioner comprises a compressor for compressing and circulating a coolant in the cooling circuit, a condenser of the air cooling type for cooling and condensing the compressed coolant, a condenser of the water cooling type for further cooling and condensing the coolant which has been condensed by the air cooling condenser, and two independent air passages through which air is supplied to both of the air and water cooling condensers, respectively.
