2. Definition and Technical Information
YK 155 MB is an innovative designed air conditioning device developed for air
conditioning minibuses up to 17 seats.
The easy-to-install unit includes a condenser and an evaporator. These units must be
mounted on the roof of the vehicle and connected to the compressor via hoses circulating
R134a refrigerant.
With its aerodynamic design, this unit only increases the height of the vehicle by 22 cm.
Thus, thanks to its design, resistance in air and fuel consumption is minimized.
It can operate in outdoor conditions at 45°. The air conditioner, which has a cooling
capacity of 10-15 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 155 MB is universal, compact and economical with all its features.
2.1 What is YK 155 MB?
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.
