Disclosed in an air conditioner including a control box having a space formed therein, a PCB arranged to form an air circulation passage in the space, the PCB having a plurality of electric components mounted thereto, a cooling module for making a first electric component of the plurality of electric components to heat exchange with refrigerant, and a circulating fan arranged in the air circulation passage to make air to flow to a second electric component of the plurality of electric components after cooled by the cooling module, thereby dissipating heat from an inside of the control box with a mixed cooling system of a refrigerant cooling system and an air cooling system, efficiently.

Air conditioner

The present invention includes a first injection tube for supplying a colloidal medium, a storage part connected to the first injection tube for receiving the colloidal medium through the first injection tube, a second injection tube connected to the storage part for supplying a colloid, a discharge tube connected to both the storage part and the second injection tube for discharging the colloidal medium coming from the storage part and the colloid coming from the second injection tube, and a free surface inversion part for inverting the free surface of the liquid in the second injection tube so as to mix the colloidal medium and the colloid in the discharge tube.

Apparatus for producing a composite material

A capacity-variable air conditioner is capable of controlling capacity and consumed electricity in response to operation mode. The refrigerant compression quantity of a compressor is variably adjusted by control of open/close operation modes via selective combination of open/close valves of bypass pipes and bypass valve of the compressor in response to the operation mode. The capacity-variable air conditioner discharges some of the refrigerant infused into the compressor while the bypass valve of the compressor is opened under energy saving operation mode, such that refrigerant circulation quantity can be adjustably reduced under the energy saving operation mode where load of the compressor is less than that of a normal operation mode, thereby enabling a reduction in the capacity and consumed electricity.

Capacity-variable air conditioner

A heat exchanger of an air conditioner comprising: at least one or more refrigerant inlets for connecting a compressor for compressing refrigerant to an expansion device for expanding condensed refrigerant via a piping and for receiving high temperature/pressure refrigerant coming from the compressor via a four-way valve; at least one or more refrigerant outlets for discharging the refrigerant to the expansion device, wherein the number of the refrigerant outlets is greater than that of the refrigerant inlets, such that same performances can be achieved for both the cooling and heating purposes albeit the heat exchanger being simplified in the structure thereof, and manufacturing cost can be reduced to thereby improve the productivity.

Heat exchanger of air conditioner

A cool air feeding system that senses a temperature of each part of a refrigerator compartment, compares the sensed temperature with a reference temperature, determines which part is to be cooled, and redistributes cool air to better cool a part of the refrigeration having a greater need to be cooled. Cool air redistribution is achieved using a single value having multiple openings. Such a valve can take the form of cylindrical manifold and a corresponding cylindrical, unitary-body flow distributor, for example.
