YK 120 S additional is an innovative designed air conditioning device developed for air
conditioning minibuses up to 15 seats.
The easy-to-install unit includes an evaporator. These units must be mounted on the roof
of the vehicle and connected to the compressor via hoses circulating R134a refrigerant.
It can operate in outdoor conditions at 45°. The air conditioner, which has a cooling
capacity of 9-12 kW, can have a heating function with the heat exchanger device. Your
air conditioner makes the waste heat generated in your vehicle's engine usable and can
provide heating power to your air conditioner with its current design. In this way, the
cooling of your engine is more effective, while your vehicle warms up.
YK 120 S is universal, compact and economical with all its features.
2. Definition and Technical Information
2.1 What is YK 120 S Additional?
2.2 How does it work?
Vehicle roof air conditioners are heat machines that provide passenger thermal comfort
by taking the heat inside the vehicle.
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. While the ambient air passed over the
evaporator heats the fluid in the evaporator and causes it to evaporate, it cools the
environment and provides thermal comfort to the passenger cabin.
