Climate control systems that include a refrigerant leak sensor are disclosed. Embodiments may include control logic, a voltage source coupled to a switch and configured to output a constant AC voltage. The switch may be coupled to a first line input and a sensor may be coupled to the switch. The first line input may be coupled to the control logic and a blower control circuit may be coupled to the control logic. In operation, the switch may receive a signal from the sensor and the signal may indicate presence of a refrigerant in the vicinity of the sensor. Thereafter, the switch may operate to electrically couple the first line input to the voltage source. The control logic may detect the constant AC voltage at the line input and cause the blower control circuit to operate a blower to disperse the leaked refrigerant.

Systems and methods for vapor compression systems having at least one multi-circuit heat exchanger and a distributor designed to receive multi-phase refrigerant from an expansion valve and evenly distribute the multi-phase refrigerant using the distributor have been developed for improved efficiency and reduced cost. The distributor may be positioned in close proximity to the expansion valve and may be oriented with respect to an output of the expansion valve to cause the refrigerant flow to impact the distributor and enhance turbulent flow to facilitate mixing of the liquid and vapor refrigerant. Channels extending from the distributor may be positioned with respect to the output of the expansion valve to facilitate even distribution of the multi-phase refrigerant flow. With each circuit of the multi-circuit heat exchanger supplied with evenly distributed multi-phase refrigerant, efficiency will be improved.
