Thermal systems with adsorber charge are completely insensitive to effects of temperature on the capillary tube and valve head. It reacts only according to the temperature of the bulb. Thus, Honeywell TMV valves with combi adsorber charge work absolutely reliable, even in icy condition or while defrosting using hot gas.

Superheat Adjustment In general the Honeywell valves should be installed with the factory setting for the used refrigerant unaltered. At combi adsorber valves the label on the capillary tube indicates how to adjust the adjusting spindle (with arrow for direction), depending on the refrigerant used. This correction of the adjustment is essential to ensure that the control performance of the valve is correct. The refrigerant used must be marked on the label. This superheat adjustment is calibrated for lowest superheating and optimum evaporator utilisation. [. . . ] This superheat adjustment is calibrated for lowest superheating and optimum evaporator utilisation. However, should it be necessary to adjust the superheat, turn the adjusting spindle as follows: Turning clockwise Turning counterclockwise = = reduced refrigerant mass flow, increase of superheat increased refrigerant mass flow, decrease of superheat One turn of adjusting spindle alters superheat setting by approx.
