2. Definition and Technical Information
The YS 50 refrigerated system is a +4 C° transport cooler. It provides suitable cooling for
volumes between 5 and 13 m³. The maximum cooling capacity is 5 kW.
The easy-to-install unit includes a condenser and an evaporator. These units need to be
mounted on the roof of the vehicle and connected to the compressor via hoses with
R134a refrigerant circulation.
With its aerodynamic design, this unit only increases the height of the vehicle by
approximately 19 cm. Thus, thanks to its design, resistance in air and fuel consumption is
minimized.
YS 50 is universal, compact and economical with all its features.
2.1 What is YS 50?
2.2 How does it work?
YS 50 refrigerated coolers are heat machines that take the heat inside the vehicle and
provide cooling of the products in the refrigerated case.
Vehicle roof air conditioners work with a vapor compression refrigeration cycle in
thermodynamics. There are 4 main parts in this cycle. These are the compressor,
condenser, evaporator and expander valve.
The refrigerant put into the heat machine is first pressurized in the compressor, and the
fluid pressure is increased from approximately 1 bar to 16 bar. Afterwards, the
temperature of the supercompressed and superheated gas in the condenser is taken and
the fluid is liquefied under extreme pressure. The high pressure liquefied fluid coming to
the expansion valve from here passes through the valve to the low pressure region and
evaporates. It needs heat during evaporation. The ambient air passed over the
evaporator heats the fluid in the evaporator and causes it to evaporate, while cooling the
products in the refrigerated case.
