An improved reverse-cycle heat pump system (100) is disclosed that comprises components to improve the efficiency of the system in the cooling mode. Specifically, the invention incorporated a conduit assembly (50) for carryin g refrigerant from one heat exchanger to the other heat exchanger, wherein the heat exchangers (20) are configured to function interchangeably as a condens er and evaporator, depending upon whether the system is operating in cooling mo de or heating mode. The conduit assembly (50) includes a coiled section (53) of tubing disposed near the heat exchanger that functions as an evaporator (20) in cooling mode. This coiled section functions as a reservoir for collecting excess refrigerant liquid from the "evaporator" during operation of the syst em in the cooling mode. Consequently, in cooling mode, heat dissipation via the condenser is thereby increased since less refrigerant liquid is contained therein, resulting in improved cooling of the conditioned area or substance.
