1. A climate control system comprising:
a refrigerant circuit configured to route a refrigerant fluid within the climate control system, the refrigerant circuit including a main circuit and a bypass circuit;
the main circuit configured to direct the refrigerant fluid from a compressor to a first heat exchanger, a metering device, a second heat exchanger, and an accumulator;
the bypass circuit configured to selectively direct a portion of the refrigerant fluid from a location between the first and second heat exchangers to a third heat exchanger, the bypass circuit including a bypass control valve and a bypass metering device, the bypass control valve located upstream of the third heat exchanger and configured to control the flow of the portion of the refrigerant fluid to the third heat exchanger, the bypass metering device configured to lower a pressure of the portion of the refrigerant fluid before the portion of the refrigerant fluid enters the third heat exchanger; and
the third heat exchanger, wherein the third heat exchanger is configured to exchange thermal energy between the portion of the refrigerant fluid and the refrigerant fluid in the main circuit while the portion of the refrigerant fluid is flowing in the bypass circuit,
wherein the third heat exchanger is an insulated tube-in-tube heat exchanger that includes an inner fluid channel and an outer fluid channel, and
wherein the third heat exchanger has a helical shape and is wrapped around the accumulator.
