Condensing unit having fluid injection
First Claim
1. A climate control system comprising:
- a compressor;
a first heat exchanger in fluid communication with said compressor;
a second heat exchanger in fluid communication with said compressor and said first heat exchanger;
a third heat exchanger disposed between said first heat exchanger and said second heat exchanger and including an inlet and an outlet;
a conduit fluidly coupled to said third heat exchanger and said compressor and operable to selectively supply fluid to said compressor;
a valve operable to control a volume of fluid supplied to said compressor via said conduit; and
a controller operable to control said valve based on a temperature difference between said outlet of said third heat exchanger and said inlet of said third heat exchanger.

Abstract
A climate control system is provided and may include a compressor, a first heat exchanger in fluid communication with the compressor, a second heat exchanger in fluid communication with the compressor and the first heat exchanger, and a third heat exchanger disposed between the first heat exchanger and the second heat exchanger and including an inlet and an outlet. A conduit may be fluidly coupled to the third heat exchanger and the compressor and may selectively supply fluid to the compressor. A valve may control a volume of fluid supplied to the compressor via the conduit. A controller may control the valve based on a temperature difference between the outlet of the third heat exchanger and the inlet of the third heat exchanger.
