Abstract
A spill over tank for an evaporator of a HVAC system may be configured to receive a refrigerant spilled over from the evaporator. The spill over tank may be configured to have an outlet that directs the refrigerant in the spill over tank out of the spill over tank. The refrigerant may flow through the outlet back to a compressor of the HVAC system. The spill over tank may be equipped with a refrigerant level sensor configured to measure a refrigerant level in the spill over tank. The measured refrigerant level in the spill over tank may be used to control and/or maintain a refrigerant level in the evaporator, and/or may be used to control a return refrigerant flow into the compressor of the HVAC system so as to manage an oil return to the compressor.
