1.10 Cooling operation and hydraulic diagrams

1.10.1 YLCA models: cooling only

1 Heat exchange takes place between the heat transfer liquid (water or glycol water) and the coolant

in the plate heat exchanger.

2 Water is cooled, and coolant is evaporated and reheated.
3 Then the Scroll compressor condenses the coolant (gas) until the condensing pressure is reached,

and the coolant goes to the air cooled condenser unit.

4 In the air cooled condenser unit, heat is exchanged between the air and the coolant.
5 The air is heated and evacuated from the cooling unit (heat rejection).
6 The coolant is condensed and sub-cooled.
7 Then the coolant (liquid) goes on to the expansion element where it is expanded until the evaporation

pressure is reached, next it goes to the plate heat exchanger to start a new cooling cycle.
