|
| Low Running cost
on cheap fuels like |
: |
High Running Cost
due to Electricity as Energy Input. |
| - Agrofuels |
: |
|
| - Furnace Oil |
: |
|
| - Waste Heat |
: |
|
|
------------------- |
| Very low
maintenance costs due to no reciprocating parts having
high wear & tear. |
: |
High maintenance
cost. |
|
------------------- |
| High plant
availability due to no reciprocating parts (only one
Centrifugal pump is moving part which has standby) |
: |
Frequent outage
on plant needs standby compressor. |
|
------------------- |
| No loss of
efficiency at part load. Efficiency improves at part load |
: |
Loss of
efficiency at part load due to fixed mechanical losses
& motor electrical losses. |
|
------------------- |
| No fouling of
Evaporator surfaces due to lubricating oil. |
: |
Possibility of
fouling due to lube oil on evaporator surfaces. |
|
------------------- |
| Small size
standby D.G. Set is sufficient. |
: |
Large D.G. Set
needed on standby. |
|
------------------- |
| Outdoor
installation, hence low civil & structural
costs. |
: |
Indoor
installation is needed due to electrical systems. |
|
------------------- |
| Low foundations
costs due to no reciprocating parts |
: |
High foundation
costs due to reciprocating compressors. |
|
------------------- |
| Long life of
plant of atleast 25 years |
: |
Low life of
Compressor |
|
-------------------
|
| No loss of
efficiency with usage |
: |
Loss of
efficiency with usage due to compressor parts wear &
tear. |
