How is pump down being conducted?
A system pump down utilizes a solenoid valve in the liquid line, when the system set-point temperature has been satisfied, the solenoid valve will close. The compressor will continue to pump refrigerant into the condenser and/or receiver, drawing it from the low side of the system.
What is pump down cycle?
The Pumpdown Cycle
When the desired box temperature is reached in the space, the thermostat will open and de-energize the liquid-line solenoid valve (Figure 1), closing the valve. The compressor will continue to run and will evacuate any refrigerant from the solenoid valve’s outlet, up to and including the compressor.

What is the difference between pump down and pump out?
Pumping down a system to a very low pressure significantly decreases the amount of residual ammonia in the equipment, thus minimizing the amount that could be released during plant tie-in procedures. A dedicated pump-out system allows pressures to be lowered even below normal system operating suction pressure.
When a system pumps down where is the refrigerant stored?
All of the refrigerant is pumped into and stored in the condenser and receiver. The compressor will continue to run, pulling refrigerant out of the cooler until the suction pressure reaches the low pressure cut-out switch setting which is usually set at 2 psig.
What does pump down mean?
Mechanics Engineering. The action or process of reducing the pressure of air or other gas inside an enclosed volume by pumping.

Is the crankcase of the compressor considered to be on the high or low pressure side of the system?
This allows the oil to travel from the oil separator to the compressor’s crankcase. Your oil separator is on the high side of the system, while the compressor crankcase is on the low side. High pressure occurs when the needle valve gets partially stuck open and goes directly into the compressor’s crankcase.
What is the purpose of a pump down AC?
The purpose of a pump down system is to prevent liquid refrigerant from “migrating” back into the compressor during an off-cycle. This prevents catastrophic damage to the compressor when the system starts up.
What will happen if the pump down solenoid is installed backward?
What will happen if the pump down solenoid is installed backward? The system will not pump-down and the compressor will not shut off.

How do you pump down a reefer compressor?
- Open suction and discharge stop valves on compressor.
- Close liquid stop valve after condenser or receiver so that liquid refrigerant can be collected in the tank. …
- Start up the compressor. …
- Keep a close eye on the suction pressure gauge!
Can you pump down a scroll compressor?
The scroll compressor can be used to pump down refrigerant in a unit as long as the pressures remain within the operating envelope. On a 410a compressor, do not allow pressure to go below 36 psi.
