What are things that can cause high recovery discharge pressures?
The three causes for high discharge temperatures are: High condensing temperature. Low evaporator pressures and temperatures. High compression ratios.
What is refrigerant discharge?
Discharge gas lines (often referred to as hot gas lines) allow refrigerant to flow from the discharge of the compressor to the inlet of the condenser. • Undersizing discharge lines will reduce compressor capacity and increase compressor work.
What is the most common problem that enters a refrigerant system?
While there are many different potential causes of compressor failure, high compressor discharge temperatures represent one of the most common problems when it comes to commercial refrigeration.
What causes refrigerant to flow?
When the piston hits the point of maximum downard displacement, it compresses the refrigerant on the upstroke. The refrigerant is pushed through the exhaust valve into the condenser. Both the intake and exhaust valves are designed so that the flow of the refrigerant only travels in one direction through the system.
What causes high discharge?
What causes high discharge temperature? High discharge temperature is the result of temperatures in the compressor head and cylinders becoming so hot that the oil loses its ability to lubricate properly. This causes rings, pistons and cylinders to wear resulting in blow by, leaking valves, and metal debris in the oil.
What causes high discharge temperature?
What does it mean when you have a lot of discharge?
Outlook. Regular vaginal discharge is a sign of a healthy female reproductive system. Normal vaginal discharge contains a mixture of cervical mucus, vaginal fluid, dead cells, and bacteria …
What causes a lot of discharge from the vagina?
Possible causes of abnormal vaginal discharge include: Certain hygiene practices, such as douching or using scented sprays or soaps Only rarely is vaginal discharge a sign of cancer. Causes shown here are commonly associated with this symptom. Work with your doctor or other health care professional for an accurate diagnosis.
What causes the leading cause of discharge delay?
The baseline measurements concluded that the leading cause for the delay was the physician delay in discharge and paperwork.
When to see a doctor about excessive discharge?
It is not always necessary to see a doctor about excessive vaginal discharge. However, a female may want to consider seeing their doctor if their vaginal discharge has an abnormal appearance.
Why do I have more discharge than normal?
Another possible cause is an excessive amount of refrigerant in the system, commonly referred to as an overcharge. This will cause the excess liquid refrigerant to take up condensing space, which will cause less space to condense the refrigerant, leading to an elevated discharge pressure.
What causes high or low discharge line temperature?
On the condenser side, anything that causes high head will also cause high discharge line temperature. Overcharge, low condenser air flow due to improper motor or blade or dirty condenser coils.
What causes high discharge pressure in a refrigeration system?
One common cause of high discharge pressure is the cooling medium (air or water) flowing across the condenser: either there is not enough or the temperature of the cooling medium is too high. Refrigeration systems operating at a higher-than-normal discharge pressure can be the result of several different issues.
What causes an evaporator to have a high discharge?
Other causes of high Discharge Superheat are a kinked or restricted liquid line, a restricted filter drier, a restricted Accurator piston or Accurator strainer or an Electronic Expansion Valve (EEV) under feeding the evaporator. Restricted condenser air flow can also contribute to high Discharge Superheat.
