Abstract

An air conditioner may include a heat exchanger having a first cooling coil and a second cooling coil inclined toward each other, an inlet formed between a lower end of the first cooling coil and a lower end of the second cooling coil to allow air to pass through, an inside air duct through which air introduced to the inlet flows, an air supply duct through which the air passing through the heat exchanger flows, a fan causing air passing through the heat exchanger to flow, and a temperature sensor sensing a temperature of the air introduced into the heat exchanger. The heat exchanger includes a plate positioned between the first cooling coil and the second cooling coil. The plate may have a sensor insertion hole into which the temperature sensing device is inserted. By measuring the temperature of the air introduced into the heat exchanger, more accurate control information may be provided.

First claim

What is claimed is:

1. An air conditioner, comprising:
a heat exchanger including:
a first cooling coil arranged along a first plane that is inclined;
a second cooling coil arranged along a second plane and is inclined, wherein refrigerant flows through the first and second cooling coils;
an inlet formed between a lower end of the first cooling coil and a lower end of the second cooling coil through which air passes; and
a plate extending between the first and second cooling coils, the plate having a first hole;

a first air duct through which air introduced to the inlet flows;
a second air duct through which air passing through the heat exchanger flows;
a fan configured to guide air through the heat exchanger;
a temperature sensor configured to be inserted through the first hole to sense a temperature of the air introduced into the heat exchange; and
a case provided between the first cooling coil and the second cooling coil, the case having a passage through which air flows wherein the temperature sensor is configured to be inserted through the case and at least partially provided in the passage.

2. The air conditioner of claim 1 , wherein the first hole is formed on a lower portion of the plate to be spaced apart from the first cooling coil and the second cooling coil.

3. The air conditioner of claim 1 , wherein the heat exchanger further includes a first bushing provided in the first hole, the first bushing being configured to maintain a position of the temperature sensor in the first hole.

4. The air conditioner of claim 1 , wherein the case is coupled to the plate.

5. The air conditioner of claim 4 , wherein the plate is formed with at least one second hole, and the case is formed with at least one hook configured to engage with the at least one second hole to secure the case to the plate.

6. The air conditioner of claim 5 , wherein the case includes a support provided in the passage and configured to support the temperature sensor at an upper side and a lower side of the temperature sensor.

7. The air conditioner of claim 1 , wherein at least one leg extends from a lower surface of the case.

8. The air conditioner of claim 7 , wherein the at least one leg includes a plurality of legs spaced apart from each other on the lower surface of the case, and the lower surface includes an opening communicating with the passage such that air is configured to flow between the plurality of the legs, into the opening, and through the passage.

9. The air conditioner of claim 1 , wherein a rear surface of the case includes a third hole through which the temperature sensor is configured to be inserted, and a second bushing is provided in the third hole, the second bushing being configured to maintain a position of the temperature sensor in the third hole.

10. The air conditioner of claim 1 , wherein the temperature sensor is provided in the passage of the case and spaced apart from an inner surface of the case.

11. The air conditioner of claim 1 , wherein the case is made of an insulating material.

12. The air conditioner of claim 1 , wherein the first and second planes are inclined toward each other, and side edges of the plate are inclined such that the plate fits between the first and second cooling coils.

13. The air conditioner of claim 1 , further comprising a gas furnace provided under the heat exchanger and configured to provide hot air.

14. An air conditioner, comprising:
an A-coil heat exchanger having an A-shaped plate and an inlet formed at a bottom rough which air passes, the plate having a first hole;
a first air duct through which air introduced to the inlet flows;
a second air duct through which air passing through the heat exchanger flows;
a fan configured to guide air through the heat exchanger;
a temperature sensor configured to be inserted through the first hole to sense a temperature of the air introduced into the heat exchanger; and
a sensor support provided inside of the A-coil heat exchanger, the sensor support having a passage through which air flows, wherein the temperature sensor is configured to be inserted through the sensor support and at least partially provided in the passage.

15. The air conditioner of claim 14 , wherein the sensor support is formed with at least one hook, and the plate is formed with at least one second hole configured to receive the at least one hook.

16. The air conditioner of claim 14 , wherein the sensor support includes a third hole through which the temperature sensor is configured to be inserted, the third hole configured to align with the first hole when the support is coupled to the plate.

17. The air conditioner of claim 14 , further comprising a compressor, a condenser, and an expansion valve which are controlled based on a sensing by the temperature sensor.

18. A heat-exchanger, comprising:
a first cooling coil arranged along a first plane that is inclined;
a second cooling coil arranged along a second plane and is inclined, wherein refrigerant flows through the first and second cooling coils;
an inlet formed between a lower end of the first cooling coil and a lower end of the second cooling coil through which air passes;
a plate extending between the first and second cooling coils, the plate having a first hole;
a case provided between the first and second cooling coils and configured to couple to the plate, the case having a passage and a second hole configured to align with the first hole when the case is coupled to the plate; wherein the passage is formed through the case such that air introduced through the inlet is configured to flow through the passage; and
a temperature sensor configured to be inserted through the first and second holes to sense a temperature of air flowing in the passage.

19. An air conditioner including the heat exchanger of claim 18 .
