Chiller metering device
WebSep 29, 2024 · Centrifugal chillers consist of the usual evaporator, compressor, condenser, and expansion device set-up but with additional rotating impellers which compress the refrigerant and transport it around the system. They are beneficial for medium to large-scale cooling operations (from 150 – 6000 tons of refrigeration). Uses of Industrial Chillers WebJul 27, 2024 · Most “active” metering devices are designed to output a set superheat (or tight range) at the outlet of the evaporator coil if the valve is provided with a full liquid line of a high enough pressure liquid (often at least 100 PSIG higher than the valve outlet/evaporator pressure).

WebAug 20, 2024 · 1. The Compressor. The Compressor can be thought of as the heart of the process. It acts like a pump to create the circulation by compressing the refrigerant gas, creating a pressure difference that drives the refrigerant around the circuit in a continuous cycle. 2. The Condenser. WebJan 25, 2024 · In a boiling pot of water, we create flash gas by increasing the water temperature until it hits the boiling temperature. At atmospheric pressure, that occurs at 212°F, which is the boiling or flashing point we are most familiar with. Inside a refrigeration circuit, we get flash gas when the pressure on the liquid refrigerant drops below the ...
