Operation, cooling and hydraulic diagram. Cool only unit YCSA 120/150

Heat exchange takes place between the heat transfer liquid
(water or glycol water) and the refrigerant in the plate heat
exchanger. Water is cooled, and refrigerant is evaporated
and reheated.
Then the Scroll compressor condenses the refrigerant (gas)
until the condensing pressure is reached, and the refriger-
ant goes to the air cooled condensing unit. In the air cooled

condensing unit, heat is exchanged between the air and
the refrigerant. The air is heated and evacuated from the
chiller (heat rejection). The refrigerant is condensed and sub-
cooled. Then the refrigerant (liquid) goes on to the expansion
valve, where it is expanded until the evaporating pressure is
reached, at which time it goes to the evaporating unit to end
the cooling cycle.
