In a vapour compression refrigeration system, liquid to the suction heat exchanger is used to Correct Answer Sub-cool the liquid refrigerant leaving the condenser

Concept:

Liquid Suction Heat Exchanger
An LSHX is a counter flow heat exchanger installed between the outlet of condenser and inlet of the compressor. In LSHX the hot refrigerant at the outlet of the condenser exchanges heats with the cooled refrigerant at the outlet of the evaporator.

Advantages:

  • Provides subcooling outside the condenser
  • Improves cycle efficiency in some cases
  • Cleans up liquid refrigerant in the suction line
  • Allows use of full evaporator surface for cooling

Concentrated fermentation liquid containing 20% (w/w) gluconic acid from an evaporator has a flow rate of 2000 kg/h and a temperature 90 °C. It needs to be cooled to 6 °C in a heat exchanger with cooling water. The cooling water has a flow rate 2700 kg/h and an initial temperature 2 °C. If the cooling water leaves the heat exchanger at 50 °C, what is the rate of heat loss from gluconic acid solution to the surroundings? Assume the heat capacity of gluconic acid is 0.35 cal/g-°C-1.
