Abstract

An air conditioning module, which can perform cooling and heating through a single module, which is capable of being compact-sized, which can prevent problems caused by condensate water because the condensate water can be easily discharged out, and which can control all of two doors for heating and cooling by a link member and an actuator.

First claim

The invention claimed is:

1. An air conditioning module comprising:
a compressor for inhaling and compressing a refrigerant;
a condenser for condensing the refrigerant compressed in the compressor;
expansion means for throttling the refrigerant condensed in the condenser;
an evaporator, which evaporates the refrigerant supplied through the expansion means, and, of which a certain area is located at an upper part or a lower part in a height direction with respect to the condenser;
a housing;
a first blowing part for blowing air to pass through the condenser to be heated;
a first door for adjusting a flow of the air passing through the condenser;
a second blowing part for blowing air to pass through the evaporator to be cooled; and
a second door for adjusting a flow of the air passing through the evaporator, wherein the air supplied through the first blowing part and the air supplied through the second blowing part by actuations of the first door and the second door is discharged to an interior of a vehicle or to outside of the vehicle, wherein the housing comprises:
a drain passageway formed in a lower space where the evaporator and the compressor are disposed;
a drain part formed at one side of the drain passageway to discharge condensate water; and
a first slope part and a second slope part, which block between the evaporator and the drain passageway and extend inclinedly in a downward direction from both side walls of the housing, and, of which certain areas of lower parts of the first slope part and the second slope part are overlapped with each other.

2. The air conditioning module according to claim 1 , wherein the housing comprises:
a first inflow part hollowed at a certain area of a lower part thereof to transfer the air to the condenser; and
a second inflow part hollowed at a certain area of a side thereof to transfer the air to the evaporator.

3. The air conditioning module according to claim 2 , wherein the housing further comprises:
a first passageway, through which the air passing through the condenser is transferred to the interior of the vehicle, and in which the first blowing part and the first door are mounted; and
a second passageway, through which the air passing through the evaporator is transferred to the interior of the vehicle, and in which the second blowing part and the second door are mounted.

4. The air conditioning module according to claim 3 , wherein the housing further comprises:
a first discharge passageway operable and closable by the first door and extends from a first discharge hole hollowed at a certain area of the first passageway to discharge the air; and
a second discharge passageway operable and closable by the second door and extends from a second discharge hole hollowed at a certain area of the second passageway to discharge the air.

5. The air conditioning module according to claim 4 , wherein the condenser comprises:
a pair of first header tanks spaced apart from each other at a predetermined interval and disposed side by side;
a first tube of which both ends are fixed to the first header tanks to form a refrigerant passageway;
a first pin interposed in the first tube; and
a gas-liquid separator connected to the first header tanks, located at right angles to a direction the first header tanks, the first tube and the first pin are formed to separate a liquid-phase refrigerant from a gas-phase refrigerant, and disposed on the first discharge passageway or the second discharge passageway,

wherein the evaporator comprises:
a pair of second header tanks;
a second tube of which both ends are fixed to the second header tanks; and
a second pin interposed in the second tube, and wherein the first header tanks positioned at a side of the condenser and the second header tanks positioned at a side of the evaporator are respectively located at the upper part or the lower part in the height direction.

6. The air conditioning module according to claim 4 , wherein during heating, the first door closes the first discharge hole and opens the first passageway and the second door closes the second passageway and opens the second discharge hole such that the air heated by passing through the condenser is transferred to the interior of the vehicle through the first passageway and the air cooled by passing through the evaporator is discharged through the second discharge hole and the second discharge passageway, and wherein during cooling, the second door closes the second discharge hole and opens the second passageway and the first door closes the first passageway and opens the first discharge hole such that the air cooled by passing through the evaporator is transferred to the interior of the vehicle through the second passageway and the air heated by passing through the condenser is discharged through the first discharge hole and the first discharge passageway.

7. The air conditioning module according to claim 1 , wherein the condenser and the evaporator are mounted horizontally.

8. The air conditioning module according to claim 1 , wherein the housing further comprises:
a partition part formed for partitioning the drain passageway from a space where the compressor is mounted; and
a hollow part hollowed at a certain area of the partition part.

9. The air conditioning module according to claim 1 , wherein the evaporator is located higher in the height direction than the condenser, and the first slope part and the second slope part are located below the evaporator and at a side of the condenser.

10. The air conditioning module according to claim 9 , wherein the first blowing part is located on an upper part of the condenser and at a side of the evaporator.

11. The air conditioning module according to claim 1 , wherein the air conditioning module has the expansion means of an orifice form of which an inner space, through which the refrigerant passes, decreases gradually and increases gradually and is embedded in the housing.

12. The air conditioning module according to claim 1 , wherein the first blowing part and the second blowing part adopt a cross flow fan type.

13. The air conditioning module according to claim 1 , further comprising actuating means linked with the first door and the second door to open and close the first door and the second door.

14. The air conditioning module according to claim 13 , wherein the actuating means opens the first door and the second door to a predetermined degree.

15. The air conditioning module according to claim 13 , wherein the actuating means comprises:
a link member for connecting the first door and the second door with each other; and
an actuator for actuating the link member.

16. The air conditioning module according to claim 15 , wherein the first door comprises a first rotary shaft and a plate part extending from the first rotary shaft, and wherein the second door comprises a second rotary shaft, a pair of support parts vertically extending in the form of a fan shape of which a center is connected with the second rotary shaft, and a closed part for connecting outer peripheries of the support parts with each other.
