Abstract

A cycle enhancement apparatus is provided. The apparatus has a first side entrance line and exit line, both connected to a first side of a refrigerant line, and a second side entrance line and exit line, both connected to a second side of the refrigerant line. One-way valves prevent flow through the first side entrance line toward the first side, through the first side exit line away from the first side, through the second side entrance line toward the second side, and through the second side exit line away from the second side. The apparatus has a cycle enhancement line. The cycle enhancement line has an entrance portion, connected to the first side entrance line and the second side entrance line, an exit portion, connected to the first side exit line and the second side exit line, and a cycle enhancement between the entrance portion and the exit portion.
