Abstract

A portable air-conditioner includes a compressor, a condenser, and an evaporator located inside a housing. The air-conditioner further includes an element, such as an electronic box, located in the air-flow path inside the portable air-conditioner between the evaporator to an axial fan. The element can be wider at its lower section than at its upper section to enhance an upwards air-flow in the air conditioner.

First claim

The invention claimed is:

1. A portable air-conditioner comprising:
a housing;
a compressor located inside the housing;
a three-row cylindrical condenser located inside the housing;
an evaporator located inside the housing;
an axial fan located inside the housing;
an airflow path located inside the housing and extending from the evaporator to the axial fan;
an element located in the airflow path between the evaporator and the axial fan;
a cool air outlet at the end of the airflow path; and
a warm air outlet,
wherein the three-row cylindrical condenser is configured to include two passes of a refrigerant stream in two inner rows of the three rows and one common pass of the refrigerant stream in an outer row of the three rows.

2. The portable air-conditioner according to claim 1 , wherein the housing is configured to rest on a horizontal surface during operation, and the element is wider at a lower section thereof than in an upper section thereof.

3. The portable air-conditioner according to claim 1 , wherein the element is conical.

4. The portable air-conditioner according to claim 1 , wherein the element houses an electronic box.

5. The portable air-conditioner according to claim 1 , wherein the housing is configured to rest on a horizontal surface during operation with the cool air outlet located at a top end of the housing, and the cool air outlet comprises an air diffuser having a first element and a second element that is separate from the first element, the air diffuser being configured to provide an air outflow in both an upwards direction and a lateral direction.

6. The portable air-conditioner according to claim 5 , wherein the first element is ring shaped and encloses an outer perimeter of the axial fan.

7. The portable air-conditioner according to claim 6 , wherein the second element comprises an inverted conical surface located radially within at least a portion of the first element.

8. The portable air-conditioner according to claim 7 , wherein the second element is configured to direct all of the upward air-stream in a direction deviating from the direction of the upward air-stream.

9. The portable air-conditioner according to claim 1 , wherein the condenser has 8 or 12 pipes per row.

10. The portable air-conditioner according to claim 9 , wherein the pipes have a diameter between 5-6 mm.

11. The portable air-conditioner according to claim 1 , wherein the condenser comprises fins having circular or elliptical holes.

12. The portable air-conditioner according to claim 1 , wherein the portable air-conditioner comprises a condenser radial fan, the radial fan comprising a housing having sealing elements provided inside the housing.

13. The portable air-conditioner according to claim 12 , wherein the sealing elements are configured to reduce a clearance distance between the radial fan and the housing.

14. A portable air-conditioner comprising:
a housing;
a compressor located inside the housing;
a three-row cylindrical condenser located inside the housing;
an evaporator located inside the housing;
a cool air outlet; and
a warm air outlet
wherein the housing is configured to rest on a horizontal surface during operation with the cool air outlet at a top end of the housing, and the cool air outlet comprises an air diffuser having a first element and a second element that is separate from the first element, the air diffuser being configured to provide an air outflow in both an upwards direction and a lateral direction; and
wherein the three-row cylindrical condenser is configured to include two passes of a refrigerant stream in two inner rows of the three rows and one common pass of the refrigerant stream in an outer row of the three rows.

15. The portable air-conditioner according to claim 14 wherein the first element is ring shaped and encloses an outside of a fan configured to draw air across the evaporator.

16. The portable air-conditioner according to claim 14 , wherein the second element is adapted to allow an upward air stream and to direct at some of the upward air-stream in direction deviating from the upward direction of the upward air-stream.

17. The portable air-conditioner according to claim 16 , wherein the second element is configured to direct all of the upward air-stream in direction deviating from the direction of the upward air-stream.

18. A portable air-conditioner comprising:
a housing;
a compressor located inside the housing;
a three row cylindrical condenser located inside the housing;
an evaporator located inside the housing;
a cool air outlet;
an element located in the housing between the evaporator and the cool air outlet; and
a warm air outlet,
wherein the three-row cylindrical condenser is configured to include two passes of a refrigerant stream in two inner rows of the three rows and one common pass of the refrigerant stream in an outer row of the three rows.

19. The portable air-conditioner according to claim 18 , wherein the condenser has 8 or 12 pipes per row.

20. The portable air-conditioner according to claim 19 , wherein the pipes have a diameter between 5-6 mm.

21. The portable air-conditioner according to claim 18 , wherein the condenser comprises fins having circular or elliptical holes.
