The most common causes of damage for reciprocating compressors is caused by high
suction from bad valves. Carbon buildup, and warps in the compressor valve prevents
them from sealing. A common cause is a high compression ration and therefor
high head pressure. Any loss of refrigerant or oil can also cause damage to valves.
If refrigerant migrates or floods parts that can cause corrosion. Undercharged
refrigerant also places a drain on the system. Any Denver air conditioning
parts company would love to help replace a compressor, but compressors are designed
to work for years. Proper care and maintenance can keep you from compressor
repairs.
High
compression
ratio comes from: a combination of high head pressure
and low suction pressure. High ratios result in high discharge temperatures.
The discharge temperature reflects the hottest part of the refrigeration system
and is therefore useful in determining an upper boundary. Denver furnace repair
techs will tell you that the AC compressor is often hotter than a heating element.
Discharge temperature can be measured by a thermistor about 3-4 inches from
the compressor.
Since the compressor's discharge is superheated
coolant, you will want a certified air conditioning repairman to install a special
thermostat. There is no direct temperature pressure relationship, so a cold
weather experienced HVAC tech is a must. The usual limit for heat in a compressor
is 225 degrees F. Prolonged exposure to this type of temperature will lead
to failure. Above this the system may start to fail from worn hoses, acid and oil
breakdown.
Some things your ac repair company can look out for to
minimize air conditioning compressor damage: Restricted liquid lines, undercharged
ac lines, plugged filters, and uninsulated suction lines.
