The suction pressure is very low in relation to the expected evaporation pressure of the cooling system VIII

The thermostatic element of the expansion valve is discharged.

Replace the thermostatic element (bulb-capillary-membrane assembly) or completely replace the valve, if the construction of the valve does not allow the replacement of components. Note: The pressure drop through the filters (Dp) can be quantified by applying a pressure gauge at the inlet and another at the filter outlet.
