2. Structural Features and Working Principle
2.1 Main Functions
SIC-A-R2 series are applicable for cooling molds to reduce products molding
cycle, also they are available in the cooling of equipments in order to maintain a
normal temperature. Besides, they are suitable for other industries with the
need of cooling.
2.1.1 Working Principle
Picture 2-1: Working Principle Diagram
When the SIC-A-R2 air-cooled water chiller starting up, compressor starts
working. Refrigerant is compressed into high temperature high pressure gas in
the process from B to C, and then be cooled when passing through the
condenser and changed into liquid. Heat is taken away by the cooling air. In the
process from C to D to E and F, the liquid refrigerant is dried and filtered by the
dry filter. After that, it passes through the solenoid valve, level sensor and then
reaches the expansion valve. In the process from F to G, the high pressure
liquid refrigerant is throttled and depressurized by the heat expansion valve and
the temperature goes down. In the process of G to A, chilled water absorbs the
heat of process water in the evaporator and returns back to the compressor.
This heat exchange process repeats until process water is cooled down to
required temperature.
18(96)
Hot-air bypass function: the compressor continues working when the process
water is cooled down to the required temperature, then the hot-air bypass valve
opens as the temperature drops to its set value. A part of the refrigerant from
the compressor passes through the bypass valve and then reach the
evaporator, balancing out part of the machine refrigerating capacity and then
goes back to the compressor without passing through the condenser. With the
help of hot-air bypass valve, the system can stay in an balanced condition and
meanwhile can keep the control accuracy at ±1℃ .

6.2 Components Maintenance
6.2.1 Condenser
SIC-A-R2 series water chiller use the air cooled fin style condenser which
installed openly, in the using time, it is hard to avoid any dust and sundries,
which will influence the heat emission effect, so it is necessary to clean the
condenser at fixed periods in order to keep its working performance. Use brush,
dust catcher or compressed air to clean the wings and copper pipe. Then use
the low pressure water to cascade the tray pipe. Note: do not let the water to
cascade on the surface of the fan motor.
94(96)
Attention!
Do the cleaning work every half-year in the environment with little dust,
but you must do the work every month in the environment with a great
deal of dusts, and under the severe environment you had better see the
situation to do the work.
6.2.2 Evaporator
The inner flank of the heat emission pipe will pile up a great deal of water
incrustation after a long time use of the evaporator, which will influence the heat
emission effect, so it is necessary to clean the evaporator at fixed periods in
order to keep its working performance. If the circulation has been under water
treatment, it is advised that firstly use hydrogen peroxide to kill bacteria and
then use a high pressure water rifle to flush it, at last check whether there is still
incrustation scale. If the circulation is not processed under water treatment,
clean it with citric acid and sulfamic acid along with inhibiter, and then flush it
with a high pressure water rifle. Passivation is need after acid washing, and the
dirt will be diacharged from the water outfall.
Attention!
Drain the water inside the evaporator and the condenser away when the
machine stop running under 0℃.
