1 - lack of refrigeration.
2 - compressor works for large periods do not stop.
3 - high temperature compressor, because it depends on the gas cooled in the reflux (decreased if the shipment is received will not be gas cooled)
4 - pressure high temperature lead to decomposition of the oil and the carbon on the valves.
5 - decrease of quality factor COPle coeffiecient de performance
The problems of increasing the shipment is:
1 - lack the level of cooling as part of the evaporator is a submerged fluid.
2 - The ice on the tube reflux.
3 - possible return coolant to the compressor and Beeston broken piston.
4 - compressor consumes more power due
