Heat Transfer in a Refrigeration System- Engineering Lab Training Systems.
Technical Description
Refrigeration systems and
heat pumps are similar in design, the former is used for cooling while
the latter is used for heating. The compact and clearly laid out
benchtop unit is a fully functional example of a typical refrigeration
system or heat pump. It has a water-cooled condenser and a water-heated
evaporator. The refrigerant is compressed and then transfers heat to the
cooling water flowing through the condenser. The refrigerant is
expanded via the expansion valve and absorbs heat from hot water pumped
through the evaporator. The hot water is heated electrically in a
collector. The heat transferred from and to the water circuits can be
determined with the aid of temperature and flow rate measuring devices.
The unit requires a supply of cooling water.
