Classification: CPC F | IPC F

Claim 0:
1. An environmental control unit comprising:
a base section;
a mobile section coupled to the base section for movement between a collapsed-storage position arranged substantially within the base section and an expanded-use position extending from the base section; and
a temperature control system coupled to the base section and the mobile section, the temperature control system configured to selectively heat or cool air flowing through the mobile section,
wherein an indoor heat exchanger of the temperature control system is coupled to the mobile section and an outdoor heat exchanger of the temperature control system is coupled to the base section, wherein the indoor heat exchanger is arranged for movement with the mobile section relative to the outdoor heat exchanger between the collapsed-storage and expanded-use positions, and wherein the indoor heat exchanger is arranged substantially within the base section in the collapsed-storage position, and
wherein the air return includes a blower unit coupled to an extendable strut and a flexible shroud coupled to the blower unit and to the carriage, wherein the extendable strut is coupled to the carriage and configured to guide movement of the blower unit relative to the carriage for movement of the air return between the retracted and extended positions, and wherein the blower unit is configured to drive air flow through the indoor heat exchanger to promote heat transfer between the indoor heat exchanger and the air.
