In a refrigeration system, why are expansion devices located closer to the evaporator?

In a refrigeration system, why are expansion devices located closer to the evaporator? Correct Answer To minimise the heat gain

Explanation:

Refrigeration system:

A refrigeration system contains a minimum of four key components i.e., compressor, condenser, expansion valve, and evaporator.

Expansion device:

  • The purpose of the expansion device is to rapidly reduce the pressure of the refrigerant in the refrigeration cycle.
  • This allows the refrigerant to rapidly cool before entering the evaporator.
  • Expansion device located closer to the evaporator in order to minimize the heat gain.
  • The most common devices are capillary tube, thermal expansion valve, electronic expansion valve

Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. What inference can be drawn from the above?
