The problem of resource consumption has been restricting the development of many industries, and the air purification engineering industry is no exception. Production enterprises have to consider the importance of energy conservation. In recent years, the energy consumption of clean rooms has attracted much attention. Then, what are the main reasons for the large energy consumption in the purification process of clean rooms, and what energy saving measures should be taken?
The main reasons for the large energy consumption in air purification projects are: general air conditioning, some only the first effect, the first stage filtration, and the higher requirements are the first effect, the middle effect and the two stage filtration treatment. The air purification requires three filters, namely the early, high efficiency filters, or primary, and sub high efficiency filter. At each level of filtration, the air is cleaner, but the cost of filtration is also increased. General central air conditioning only 10 times below /h and ventilation frequency, clean air conditioning system in more than 12 /h, even more than in the general central air conditioning ventilation times, therefore, the energy consumption per square meter of the clean air conditioning system than the general central air conditioning system is 10 ~ 20 times.
Clean room energy-saving measures: the purification operation room constant temperature, clean air conditioning system in operation room should be independent of the cold and heat sources, to avoid excessive seasonal hospital central air conditioning when disabled, clean room temperature is not constant; set one or two air volume, by adjusting the first and two return ratio, two air return system can eradicate the not only eliminates the reheat power consumption, reduce the cold load and playing surface cooler; heat recovery, refrigeration machine is discharged into the waste heat of condensing heat in the atmosphere, through recycling can be used as a good source of reheat. Many enterprises use air cooling machines in their clean rooms, which can be installed and installed to recover heat, which is more economical than electric heating and boiler hot water.
