Claim 13:
14. An evaporation unit, comprising:
a secondary evaporator configured to:
receive a flow of refrigerant discharged by a primary condenser disposed external to a housing;
receive a first supply airflow introduced into the housing; and
transfer heat from the first supply airflow to the flow of refrigerant as the first supply airflow passes through the secondary evaporator to generate a second airflow;

a first valve disposed upstream of the secondary evaporator configured to direct at least a first portion of the flow of refrigerant discharged by the primary condenser to the secondary evaporator;
a secondary metering device;
a primary evaporator configured to:
receive the flow of refrigerant from the secondary metering device or the first valve;
receive the second airflow from the secondary evaporator; and
transfer heat from the second airflow to the flow of refrigerant as the second airflow passes through the primary evaporator to generate a third airflow;

a primary metering device disposed upstream of the primary evaporator; and
a secondary condenser configured to:
receive the flow of refrigerant from the secondary evaporator;
receive the third airflow from the primary evaporator; and
transfer heat from the flow of refrigerant to the third airflow as the third airflow passes through the secondary condenser to generate a first output airflow.
