Product Name: Heat Exchangers in the Refrigeration 

                            Circuit - Education Simulator

Model Name: YESR-E3450

Features and Description

• Heat exchangers are an elementary part of refrigeration systems

• During cooling, they are used to absorb the energy of the 

   refrigerant by evaporation

• During heating, they discharge the energy set free during

   the condensation of the refrigerant

• They are also used for internal energy transfer during

   superheating or supercoiling of the refrigerant

• Dependent on the media, a difference is made between air / 

   refrigerant, water / refrigerant and refrigerant / refrigerant heat exchangers

• Dependent on the constructive design, 

   a difference is also made between coaxial, finned tube, 

   plate or shell & tube heat exchangers

• The refrigeration circuit includes as evaporator an air cooling finned

   tube heat exchanger and a water-heated plate heat exchanger,

   as superheater a tubular heat exchanger, and

   as condenser a water-cooled coaxial coil heat exchanger

• These heat exchangers are the ones used most commonly in refrigeration

   and fulfil different functions dependent on the system type.

   A finned tube heat exchanger can e.g. also be used as a condenser

• The components are arranged clearly at the front

• By measuring the mass flow rates and the inlet and outlet temperatures,

   the transferred energy fluxes can be determined
