What is the principle of waste heat recovery Good for business

[Why] Air compressors are widely used. During their long-term, continuous operation, electrical energy is converted into mechanical energy and thermal energy according to the principle of energy conservation. Waste heat is lavishly wasted into the environment. Air compressors generate heat energy, which not only has high operating costs, but also has serious environmental pollution. For example, this part of the heat energy is recycled for enterprise heating, industrial water, hot water air-conditioning... so as to solve the considerable economic burden of using hot water for social enterprises.

　　 [Benefits of air compressor heat recovery] ① The operating conditions of the air compressor are significantly improved, the temperature of the air compressor is reduced by 8 to 10°C, and the lubrication life is effectively extended.

　　② The use of waste heat saves energy to the utmost extent and saves unnecessary costs for hot water production.

　　③ Low input cost, high comprehensive recovery rate, safety and reliability, and good economic benefits.

　　【Principle of air compressor heat recovery】① The energy utilization of the air compressor.

　　 Compressed air system is one of the most energy-consuming areas of the factory

Most of the energy consumed by compressor operation is converted into heat energy during the compression process. This heat energy is usually discharged in the cooling process and wasted in typical air cooling methods. 25% of the compressor energy flow is potentially recoverable, but this energy It is still wasted.

　　② Waste heat utilization, heat recovery:

　　 Energy is limited. Instead of wasting it, it is better to recycle this heat, which will not only reduce energy costs, produce economic benefits, but also reduce emissions, which is conducive to environmental protection.

　　③ Heat recovery machine:

In the compressor energy flow, 75% of the energy wasted is equivalent to 1/4 of the input power of the air compressor, and its temperature is usually between 80°C (winter) and 100°C (summer). For example: a 75KW air compressor, the power wasted only by heat energy is 18.75KW, and 13500 kWh of electricity is wasted a month. The heat recovery machine uses this waste heat to exchange cold and heat, and uses this heat to heat domestic or production water.

　　Because it is not a simple and traditional form of heat and cold exchange, the heat exchange effect of the heat recovery machine has been greatly increased to 1.8-2 times, thus ensuring the effect of domestic hot water and production technology, and producing truly calculable economic benefits.
