Abstract
An HVAC system includes a refrigerant liquid-gas separator. The liquid-gas separator is thermally coupled to electronics to transfer heat away from the electronics, and assist in vaporizing liquid refrigerant. The liquid-gas separator device includes a refrigeration section configured to couple to a refrigeration loop, and electronics thermally coupled to the refrigeration section. The refrigeration section includes: (a) a refrigerant inlet configured to receive refrigerant from the refrigeration loop; (b) a refrigerant outlet configured to release vapor refrigerant to the refrigeration loop; and (c) a cavity coupled to the refrigerant inlet and the refrigerant outlet, the cavity configured to separate liquid refrigerant from vapor refrigerant. During use of the HVAC system, heat from the electronics board is transferred to the refrigerant. The liquid-gas separator includes a check valve configured to inhibit flow of refrigerant into the liquid-gas separator device via the refrigerant outlet.
