Abstract: A vapor compression system that includes a baffle that separates a first condenser and a first fan from a second condenser and a second fan. A controller that switches between first and second modes of operation. In the first mode of operation the controller closes a valve to block a flow of a refrigerant through a first condenser and turns off the first fan. In the second mode of operation the controller opens the valve to enable the flow of the refrigerant through the first condenser and turns on the first fan.

Abstract: The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) system that includes a drain pan. The drain pan is configured to collect condensate into a basin of the drain pan from an evaporator of the HVAC system and to direct the condensate from the basin via a drain port of the drain pan. A draining surface is formed in the basin and includes a compound slope including a first slope extending along a length of the drain pan and a second slope extending along a width of the drain pan. A raised surface extends from the draining surface and includes protrusions extending from a spine that extends along a side of the drain pan. The raised surface is configured to support the evaporator of the HVAC system.
