1. Refrigeration System Design

Energy optimization – Rules of thumb

1K higher condensing temperature

1% less cooling capacity

3% higher power consumption

1K lower evaporating temperature

5 to 8% less cooling capacity

3% lower COP

3. Heat Recovery Solutions

• Using Desuperheaters for hot water production;

• Using Heat Recovery Solution for compressor oil cooling

• Heat Pump Solution


Heat Recovery - Desuperheater


Heat energy sourced from cooling tower / dry cooler using heat rejection from existing refrigeration plant

Cascade exchanger system

Remember:

Additional savings on water consumption and fan power

Heat Pump Solution


Use The Energy Twice – Heat Pump Solution


4. Some Additional Value Engineering Products

• Economizer

• Air Purger

• Water, Dirt and Oil Purifier (WDO Unit)

• Condenser Pressure Optimizer (CPO)

Optional – adding Economizer

- Adds value at large differential pressures- Frequently used for low temperature applications- Considerable increased capacity- Significant improved efficiency


Automatic air purger GP2Improves performance and reduces operating costs of industrial ammonia refrigeration equipment

The presence of non-condensable gasses in the condenser leads to poorer heat transmission between refrigerant vapour and cooling water, and this reduces the condenser capacity.


Water, Dirt & Oil PurifierKeep your plant clean and save money

1% water content in ammonia

2% less cooling capacity

2% higher power consumption


SABROE CP Optimiser™Automatic device for balancing R717 condensing pressure against compressor efficiency

The CP Optimiser automatically calculates energy balancebetween compressor energy consumption and the energyrequired to reduce condensing pressure, taking intoaccount changing loads and conditions. This paves theway to considerable savings on energy bills, which meansthe CP Optimiser normally pays for itself within a matterof months.


5. Qualified Operation & Maintenance and using genuine spare parts

• Genuine parts result in lower energy consumption;

• Qualified service helps to maintain plant in optimal condition;

• Optimization of plant operation;

It is important to optimise the operation continuously, as this will secure that the

plant is adjusted to the optimal actual operation

conditions. This gives lowest possibly energy

consumption
