Abstract
A heating, ventilation and air conditioning (HVAC) system includes a condenser to condense a flow of refrigerant into a liquid state. The system further includes an economizer assembly having at least one separator chamber to separate liquid refrigerant from vapor refrigerant. The economizer assembly shares an upper common wall with at least a portion of the condenser and the flow of refrigerant from the condenser into the economizer assembly proceeds through a flow opening in the upper common wall. A falling film evaporator exchanges thermal energy between the liquid refrigerant and a medium flowed through a plurality of evaporator tubes in the evaporator.

A heating, ventilation and air conditioning (HVAC) system comprising:
- a condenser to condense a flow of refrigerant into a liquid state;
- an economizer assembly including at least one separator chamber to separate liquid refrigerant from vapor refrigerant, the economizer assembly sharing an upper common wall with at least a portion of the condenser and the flow of refrigerant from the condenser into the economizer assembly proceeding through a flow opening in the upper common wall;
- and
- a falling film evaporator to exchange thermal energy between the liquid refrigerant and a medium flowed through a plurality of evaporator tubes in the evaporator.
A method of operating a heating, ventilation and air conditioning (HVAC) system comprising:
- condensing a flow of refrigerant into a liquid state in a condenser;
- flowing the flow of refrigerant from the condenser to an economizer assembly via a flow opening in an upper common wall shared by the condenser and at least a portion of the economizer assembly;
- separating liquid refrigerant from vapor refrigerant in the flow of refrigerant at at least one separator chamber of the economizer assembly;
- and
- flowing the liquid refrigerant into a falling film evaporator to exchange thermal energy between the liquid refrigerant and a medium flowed through a plurality of evaporator tubes in the evaporator.
