The fan must be running for heating or cooling to occur. If Y1 is closed (first stage of cooling is energized), then the unit control will first check the ability to use the economizer. If the economizer can be used, then the unit control will modulate the damper open to maintain the low-load economizer leaving air temperature set point.. An economizer is a type of sub-cooler that uses part of the total refrigerant flow from the condenser to cool the rest of the refrigerant flow (see Figure 10.13). The evaporated refrigerant then enters the compressor at an intermediate pressure level. The cold gas from the economizer can also be used to provide extra cooling for the compressor.
