Abstract
A system for providing heating and cooling to an aircraft has a single compressor for compressing and heating a fluid, a first zone and a second zone. The first zone has a first expansion valve without a condenser and a first heat exchanger removing heat from or adding heat to the first zone. The compressed fluid passes through the first zone and the first expansion valve. The second zone requires cooling and has a second expansion valve without a condenser and a second heat exchanger for removing heat from the zone. The compressed fluid passes through the second expansion valve after going through the first expansion valve and before passing through the second heat exchanger.
