What is an Evaporator Coil? 

Evaporator Coil is a significant device used in the low-pressure side of a refrigeration. The fluid refrigerant from the valve goes into the evaporator and changes into vapor. Evaporator coil retains the warmth from the encompassing and is cooled by the methods for refrigerant. The temperature of boiling refrigerant in the evaporator should be less than that of the surrounding medium. The evaporator gets cold and stays cold because of the accompanying two reasons.

  • The temperature of the evaporator coil is low because of the low temperature of the refrigerant inside the loop.
  • The low temperature of the refrigerant stays unaltered in light of the fact that any warmth it retains is changed over to the inactive warmth as bubbling continues.

Evaporator Coil

Type of Evaporators

The evaporators are named per their determinations like development, heat move, working conditions and so forth. We should talk about different kinds of evaporators now.

According to the type of construction

  • Bare tube coil evaporator
  • Finner tube evaporator
  • Plate evaporator
  • Shell and tube evaporator
  • Shell and coil evaporator
  • Tube in tube evaporator

According to the manner in which liquid refrigerant is fed

  • Flooded evaporator
  • Dry expansion evaporator

According to the mode of heat transfer

  • Natural convection evaporator
  • Forced convection evaporator

According to the operating conditions

  • Frosting evaporator
  • Non-Frosting evaporator
  • Defrosting evaporator

Capacity of an evaporator

The measure of warmth consumed by evaporator over a fixed time frame is known as the Capacity of an evaporator. capacity of an evaporator. It is given by 

Q = UA(T2 – T1)   W or J/s


Factors Affecting Heat Transfer Capacity of an Evaporator

The presentation of evaporators relies on numerous components given underneath.

  • The material utilized for construction of evaporators
  • Temperature contrast between the refrigerant
  • Speed of refrigerant
  • Thickness of  coil
  • Contact surface zone
