  • the condensing device comprises a compressor, a condenser (condensing heat exchanger) and a blower fan, and cools a refrigerant
  • the evaporating device comprises an evaporator (evaporating heat exchanger) , a cooling fan and a capillary tube, and cools room air.
  • Conventional air conditioners have been classified into separated-type air conditioners and integrated-type air conditioners according to the method of combination of the evaporating device and the condensing device.
  • the separated- type air conditioners are realized such that the evaporating device and the condensing device have respective housings. Furthermore, the indoor unit having the evaporating device is installed outdoors, while the outdoor unit having the condensing device is installed indoors. The indoor unit and the outdoor unit are coupled together by means of a refrigerant pipe having a predetermined length.
  • the separated-type air conditioners are advantageous in that, because the unit having the condensing device which generates operational noise, which disturbs people around the device, is installed outdoors, it maintains a silent indoor atmosphere.
  • the separated-type air conditioners are problematic in that users of the air conditioners cannot easily move the indoor units or the outdoor units.
  • the integrated-type air conditioners are realized such that the evaporating device and the condensing device are commonly installed in a single housing.
  • the integrated-type air conditioners are advantageous in that users can easily move the air conditioners.

  • the present invention relates to portable water-cooled air conditioners which are easily movable and provide high cooling efficiency while reducing operational noise.
  • Conventional portable air conditioners have been typically designed as air-cooled air conditioners which are provided with air-cooled condensing devices using a large amount of room air to cool refrigerant.
  • the air-cooled air conditioners are problematic in that, if the amount of room air to be used as cooling air is increased, the energy efficiency of the air-cooled air conditioners is reduced. Therefore, to enhance the energy efficiency of the portable air conditioners, it is required to reduce the amount of room air to be used for cooling the refrigerant.
  • water-cooled condensing devices have been proposed and used. The water-cooled condensing devices are realized such that the devices cool refrigerant using both cooling water and cooling air at the same time, so that the water-cooled condensing devices can reduce the amount of room air to be exhausted to the outside of the housing.

  • the drain pan 117 is installed in the housing 101 so as to only collect water condensed from air at the evaporating device 110, the drain pan 117 does not hermetically divide the interior of the housing 101 into the upper compartment (a) and the lower compartment b. In other words, air can freely flow between the upper compartment (a) and the lower compartment (b) in the conventional portable water-cooled air conditioner 100. However, operational noise generated from the condensing device 130 in the lower compartment (b) is not intercepted by the drain pan 117, but is directly transmitted to the upper compartment (a) .
  • the evaporating device 110 installed in the upper compartment (a) of the housing 101, comprises a longitudinal cooling fan 113, a plurality of evaporating heat exchangers 115 placed around the cooling fan 113, and the drain pan 117 placed below the evaporating heat exchangers 115.

  • the above-mentioned conventional water-cooled condenser 140 is operated through an opposite directional flowing system, in which the cooling water and the cooling air flow in opposite directions. Described in detail, the cooling water flows downwards from a position above the condensing heat exchanger 144, while the cooling air flows upwards from a position below the condensing heat exchanger 144.
  • the opposite directional flow system reduces the heat exchanging efficiency because the hot exhaust air heats the cooling water sprayed from the water sprayer 145 while the exhaust air flows upwards from the position below the condensing heat exchanger 144. Therefore, the amounts of cooling air and cooling water used to cool the condensing heat exchanger 144 are increased.
  • the amount of cooling air used is increased, the amount of room air to be discharged to the outside of the housing 101 through the exhaust hose 148 is increased, thus reducing the energy efficiency of the air conditioner.

Due to the air inlet holes 105, the operational noise generated from both the blower fan 143 and the compressor is transmitted to the room through the air inlet holes 105, thus upsetting those around the air conditioner. Furthermore, in the conventional portable water- cooled air conditioner 100, the exhaust hose 148 and the blower fan 143 are placed adjacent to each other, so that the operational noise of the blower fan 143 is discharged to the outside of the housing 101 along with exhaust air through the exhaust hose 148.
