Industrial Refrigeration Units

Industrial Refrigeration Units

Industrial Refrigeration Units are classified as follows,

  1. Condenser Units
  2. Evaporator Units



The evaporator is to receive low-pressure, low temperature fluid from the expansion valve and to bring it in close thermal contact with the load.

  • The refrigerant takes up its latent heat from the load and leaves the Evaporator as a dry gas.
  • The function of the evaporator will be to cool gas, liquid or other Product loads.
  • In most cases air or a liquid is first cooled, and this is then used to Cool the load. e.g., in a cold-room air is cooled and this air cools the Stored produce and carries away heat leaking through the structure; In a water chiller, water is circulated to cool the load, etc.

Types Of Evaporators

  1. Shell & Tube Evaporators
  2. Brazed plate type Evaporator
  3. Tube Coils / Tube Bundles Evaporator


Condenser is an important component of any refrigeration system. In a typical refrigerant condenser, the refrigerant enters the condenser in a superheated state. It is first de-superheated and then condensed by rejecting heat to an external medium. The refrigerant may leave the condenser as a saturated or a sub- cooled liquid, depending upon the Temperature of the external medium and design of the condenser. Next to compressors, proper design and Selection of condensers and evaporators is very important for satisfactory Performance of any refrigeration system.

Type Of Evaporators

  1. Air Cooled Condenser Coil
  2. Water Cooled Shell & Tube Condenser with Cooling tower Water Circulation.
  3. Evaporative condensers
  4. Heat pump
