Working at higher Temperatures of the Evaporator
Table 3.2 shows the change of the cooling capacity, power consumption and power consumption for a particular system vapour compression with evaporator, the refrigerant temperature of the gas. It can be seen that the higher the temperature, the higher the power, the higher the energy consumption and reduce the specific power consumption (kW/TR). This clearly indicates that the cooling effect increases in a larger proportion than energy consumption, thereby system will cool faster and off.
A rough rule of thumb is that for every 1C above the temperature of the evaporator, the specific energy consumption to decline by approximately 2%to 3%.
The Temperature increase of the cooling Water set Point
Rationale temperature settings for technological applications need to be revised, while maintaining the existing high energy costs in the field of view. The aim is to avoid unnecessary exposure to cold, without prejudice to the production, quality and safety.
Rising energy prices have forced many industries to experiment and stabilization work at high temperatures.
Improve the Distribution of air in the cold storage Warehouses
In refrigeration units, one large coil can result in uneven temperature in a cold room, which in turn leads to lower temperature settings. Replacement of one large coil-fan diffuser units (for better air distribution) less, wall or ceiling mounted small fan-coil units can help reduce the temperature parameters (compressor) and significant energy savings.
Improving the Dissemination and Circulation Air in air-Conditioned Rooms, some air-conditioning systems, lower than the temperature set on the problems of poor air distribution; making changes in the ducts can be a more economical solution than ever pay more for electricity. In rooms with air conditioning, the use of ventilation fans can provide obviously, comfort and help raise the room temperature settings about 26C instead of 24C. Quiet fans may be hidden behind the suspended grid to make sure that the design is not affected. Reduction of electricity consumption in the refrigeration machine will be much greater than that consumed circulation fans...
