Abstract

A fan assembly is described comprising a refrigeration system, an airflow generator and a condensation collector. The refrigeration system comprises a first heat exchanger and a second heat exchanger. The airflow generator is for generating an airflow over the second heat exchanger, and the condensation collector is for collecting condensate that forms on the second heat exchanger.

First claim

1 . A fan assembly comprising:
a refrigeration system comprising a first heat exchanger and a second heat exchanger, the second heat exchanger being located above the first heat exchanger; an airflow generator for generating an airflow over the second heat exchanger; and a condensation collector for collecting condensate that forms on the second heat exchanger, wherein the condensation collector comprises a tray located between the first heat exchanger and the second heat exchanger.

2 . The fan assembly as claimed in claim 1 , wherein the tray is removable from the fan assembly.

3 . The fan assembly as claimed in claim 1 , wherein the condensation collector further comprises a bottle, and the tray comprises a drain through which condensate collected by the tray drains into the bottle.

4 . The fan assembly as claimed in claim 3 , wherein the tray and the bottle are each removable from the fan assembly.

5 . The fan assembly as claimed in claim 3 , wherein the first heat exchanger is annular in shape and comprises a gap within which the bottle is located.

6 . The fan assembly as claimed in claim 1 , wherein the second heat exchanger is annular in shape.

7 . The fan assembly as claimed in claim 1 , wherein the fan assembly comprises a filter assembly for filtering the airflow, and the filter assembly surrounds the second heat exchanger.

8 . The fan assembly as claimed in claim 7 , wherein:
the fan assembly comprises a main body; the filter assembly comprises a seal for sealing the filter assembly against the main body; the tray is located downstream of the seal; and the tray is removable from the main body by first removing at least a part of the filter assembly from the main body.

9 . The fan assembly as claimed in claim 7 , wherein:
the fan assembly comprises a main body; the filter assembly comprises a first seal for sealing the filter assembly against the main body; the tray comprises a second seal for sealing the tray against the main body; and the tray is removable from the main body independently of the filter assembly.

10 . The fan assembly as claimed in claim 1 , wherein the condensation collector has a capacity of greater than 200 ml.

11 . The fan assembly as claimed in claim 1 , wherein the second heat exchanger surrounds a major portion of the airflow generator.

12 . The fan assembly as claimed in claim 1 , wherein the fan assembly comprises a thermal store, and the first heat exchanger is configured to exchange heat with the thermal store.

13 . The fan assembly as claimed in claim 1 , wherein the first heat exchanger and second heat exchanger are cylindrical in shape.

14 . The fan assembly as claimed in claim 1 , wherein the refrigeration system comprises a compressor, and the first heat exchanger surrounds a major portion of the compressor.

15 . The fan assembly as claimed in claim 1 , wherein the fan assembly comprises a compressor for moving a refrigerant between the first heat exchanger and the second heat exchanger, and a metering device for reducing a pressure of the refrigerant.

16 . A fan assembly comprising:
a refrigeration system comprising a first heat exchanger and a second heat exchanger; an airflow generator for generating an airflow over the second heat exchanger; and a condensation collector for collecting condensate that forms on the second heat exchanger, wherein the condensation collector comprises a bottle, and the first heat exchanger is annular in shape and comprises a gap within which the bottle is located.

17 . The fan assembly as claimed in claim 16 , wherein the bottle is removable from the fan assembly.

18 . The fan assembly as claimed in claim 16 , wherein the second heat exchanger is located above the first heat exchanger.

19 . The fan assembly as claimed in claim 16 , wherein the condensation collector further comprises a tray located beneath the second heat exchanger, and the tray comprises a drain through which condensate collected by the tray drains into the bottle.

20 . The fan assembly as claimed in claim 19 , wherein the tray and the bottle are each removable from the fan assembly.
