Abstract

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.

Claims

1. An air conditioner comprising:

a compressor having sucking and discharging ports;

a condenser of the air cooling type having an inlet port connected to the discharging port of the compressor, an outlet port, and an air inlet side;

a condenser of the water cooling type having an inlet port connected to the outlet port of the condenser of the air cooling type and an outlet port;

a regulator connected to the outlet port of the condenser of the water cooling type;

an evaporator connected between the regulator and the sucking port of the compressor and having an air inlet side, the evaporator being located adjacent to the condenser of the air cooling type;

two independent air passages each having an opening through which air is taken in, the condensers of the air and water cooling types located adjacent tot he openings of the air passages, respectively; and

an air filter detachably arranged to cover the air inlet sides of the air cooling type condenser and the evaporator.

2. The air conditioner according to claim 1, further comprising a drain pan located under the evaporator and having a peripheral wall and air filter guides protruding outward from the peripheral wall, the air filter being positioned by the air filter guides.

3. The air conditioner according to claim 1, further comprising:

a body of the air conditioner;

a motor housed in the body and having a rotating shaft directed in the vertical direction;

a fan of the centrifugal multi-blade type attached to the rotating shaft of the motor; and

a casing enclosing the fan and having a sucking opening in the axial direction thereof and a blowing opening in the circumferential direction thereof,

the vertical dimension of the blowing opening of the casing being smaller than that of the fan and the transverse dimension thereof being larger than the diameter of the fan but smaller than the width of the air conditioner body.

4. The air conditioner according to claim 1, further comprising:

a sprinkler means for sprinkling water over the water cooling type condenser;

a drain hose connected to the sprinkler means to drain outside the air conditioner body water collected in the sprinkler means; and

a drain hose housing section formed integral to the rear side of the air conditioner body and enabling the open front end portion of the drain hose to be fitted into the section while keeping the drain hose bent upward on the way of it.

5. The air conditioner according to claim 4, wherein the drain hose housing section includes a cut-away portion extending from a lower edge of the rear side of the air conditioner body to a certain height, and plural curved pieces formed on the top of the cut-away portion, projecting alternately forward and backward, and wherein each of these curved pieces is made semi-circular and when the adjacent ones projected forward and backward are combined with each other, they form a circle.

6. An air conditioner comprising:

a compressor for compressing and circulating a coolant in a cooling circuit;

a condenser of the air cooling type for cooling and condensing the compressed coolant and having an air inlet side;

a condenser of the water cooling type for further cooling and condensing the coolant which has been cooled and condensed by the air cooling type condenser.

7. The air conditioner according to claim 6, further comprising a drain pan located under the evaporator and having a peripheral wall and air filter guides being protruding outward from the peripheral wall, the air filter being positioned by the air filter guides.

8. The air conditioner according to claim 6, further comprising:

a body of the air conditioner;

a motor housed in the body and having a rotating shaft directed in the vertical direction;

a fan of the centrifugal multi-blade type attached to the rotating shaft of the motor; and

a casing enclosing the fan and having a sucking opening in the axial direction thereof and a blowing opening in the circumferential direction thereof,

the vertical dimension of the blowing opening of the casing being smaller than that of the fan and the transverse dimension thereof being larger than the diameter of the fan but smaller than the width of the air condition body.

9. The air conditioner according to claim 6, further comprising:

a sprinkler means for sprinkling water over the water cooling condenser;

a drain hose connected to the sprinkler means to drain outside the air conditioner body water collected in the sprinkler means; and

a drain hose housing section formed integral to the rear side of the air conditioner body and enabling the open front end portion of the drain hose to be detachably fitted into the drain hose housing section while keeping the drain hose bent upward on the way of it.

10. The air conditioner according to claim 9, wherein the drain hose housing section includes a cut-away portion extending from a lower edge of the rear side of the air conditioner body to a certain height, and plural curved pieces formed on the top of the cut-away portion, projecting alternately forward and backward, and wherein each of these curved pieces is made semi-circular and when the adjacent one projected forward and backward are combined with each other, they form a circle.

11. An air conditioner comprising:

a compressor having sucking and discharging ports;

a condenser of the air cooling type having an inlet port connected to the discharging port of the compressor and an outlet port;

a condenser of the water cooling type having an inlet port connected to the outlet port of the condenser of the air cooling type and an outlet port;

a regulator connected to the outlet port of the condenser of the water cooling type;

an evaporator connected between the regulator and the sucking port of the compressor;

an air conditioner body housed the compressor, the air and water cooling type condensers, the regulator and the evaporator,

a sprinkler for sprinkling water over the water cooling type condenser;

a drain hose having an open front end portion, connected to the sprinkler to drain outside the air conditioner body water collected in the sprinkler; and

a drain hose housing section formed integral tot eh rear side of the air conditioner body and enabling the open front end portion of the drain hose to be fitted into the section while keeping the drain hose bent upward, the drain hose housing section including a cut-away portion extending from a lower edge of the rear side of the air conditioner body, and plural curved pieces formed on the top of the cut-away portion, projecting alternately forward and backward, and wherein each of these curved pieces is semi-circular and form a circle when the adjacent ones projected forward and backward are combined with each other.

12. An air conditioner comprising:

a compressor for compressing and circulating a coolant in a 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 cooled and condensed by the air cooling type condenser;
