ZM6152 Heat Exchangers in the Refrigeration Circuit Refrigeration
Training Equipment
1. Overview
* Typical heat exchangers from refrigeration1
* Different media: air / refrigerant,refrigerant / refrigerant and
water / refrigerant1
* Effect of superheating and supercooling of the refrigerant on the
cyclic process
2. Technical 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
supercooling 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 of the trainer 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.
The well-structured instructional material sets out the
fundamentals and
provides a step-by-step guide through the experiments.
