Basic Mechanic Knowledge of Refrigeration Systems
Industrial refrigeration systems often include air handling, condensing, drying, desiccating and chillers. Refrigeration is classified into two types; positive pressure and negative pressure refrigeration. Positive pressure refrigeration pumps circulate heated water through cooled lines while negative pressure pumps circulate cooled or warm air through cooled lines. In the UK, there are two main types of refrigeration including air-source and water-injected chillers. Air-source refrigeration requires an injection of a refrigerant into the lines to chill the air and remove heat. Water-injected chillers are similar but use water instead of air to chill the water.
