Economizers
Improving COP in cooler systems
An economizer is a type of subcooler that uses part of the total refrigerant flow from the condenser to cool the rest of the refrigerant flow. 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.
Economizer system
An economizer system and a log P/h diagram. The refrigerant flow is divided after point (b). The smaller flow (m1) is evaporated at an intermediate pressure to cool the main flow (m2). The cold intermediate gas (f) enters the compressor in a special economizer port.
SWEP products that work as economizers
SWEP economizers improve the COP of the system by increasing subcooling from the economizer unit.
