The point of the equalizing line is to sense the actual suction pressure At The Bulb Location.

. Lets say the heat pump was set to heating mode and refrigerant was flowing through the indoor air handler at 100F38C. It is the most common and easy access element to adjust the TXV to make sure the bulbs adjustment. The minimum efficiency for modern AC units is 13 SEER. If you are ready to adjust the TXV you must do some preparation before it.

Ive run across a good size 450k BTUh chiller and am puzzled by the placement of the bulbs for the expansion valves Alco THR. TXV Thermostatic Expansion Valve Sensing Bulb PositionThis is about the Thermostatic Expansion Valve TXV Temperature Sensing Bulb Placement. The TXV sensing bulb or sensor on an EEV provides the opening force for.

On a similar chiller the TXV bulbs were located at the lower quadrants of the suction line leaving the evaporator. In this short podcast episode Bryan talks about the placement of the TXV sensing bulb. Before installing the TXV install one O-ring on the Liquid Line Fitting. Danfoss Thermostatic Expansion Valve Installation Instructions.

An opposing pressure in the TXV is suction pressure. Its typically located within six inches of the sensing bulb at the top of the suction line before traps. Bulb Placement Issue. TXV Bulb placement.

It heat soaks long enough to reach this. TXV Sensor Bulb. The sensing bulb of a thermostatic expansion valve that controls the valve clamped to the refrigerant suction line where it monitors. I go over wha.

Item 8 is only used with TMM4 air handler. DO NOT oil threads. The orientation and location of the TXV bulb has a major influence on the system performance. The txv bulb reaches this temperature because it is against the pipe and warpped with insulation.

In addition it should be fixed and strapped correctly and tightly. The bulb should be allocated at the right place. He also explains how it affects the opening force on the TXV. TXV Installation Instructions 6.

On this unit the bulbs are located at the very top of the suction lines. Install the other O-ring. When to Adjust a TXV Valve. For suction lines greater than 2 inches place the sensing bulb at the 4 or 8 oclock position.

So unless there is pressure drop between the equalizing line connect and the sensing bulbs location - anywhere will work OK. If a TXV uses a gas-charged maximum operating pressure MOP power element the sensing bulb needs to be wrapped to ensure it reads true pipe temperature. Never place the sensing bulb at the 6 oclock position. It is recommended that the TXV bulb be installed parallel to the ground on a horizontal plane.

7B-2 shows the recom-mended position for the TXV bulb installation in the. With the bulb properly mounted with copper straps I measured a superheat of 168 F. Danfoss thermostatic expansion valves TXVs are designed to calculate the refrigerant at the correct rate in the cooling coil.
