Briefly describe the advantages of direct-heating air compressor water heaters

The air compressor oil and gas residual heat can reach up to 93% of the air compressor shaft power, and the utilization rate is the highest. The energy saving benefit is more than twice that of the plate heat exchanger, and the hot water production is also the most.

2. Major changes in heat exchange technology to address the possible penetration of water/oil.

Heat exchanger oil and gas separation, high temperature oil, gas exchange heat through high thermal conductivity materials, there is no place where the two fluids can penetrate each other, so there is no possibility of oil and water penetration.

3. Solve major technical problems, can easily handle the scale of the heat exchanger.

In the process of manufacturing hot water in air compressor water heater, CaCO3 in the water will be flocculated and deposited in a large amount, resulting in a large amount of scale. It has been used for 1 to 2 years in plate heat exchangers, but it is clean, but the cleaning is complicated. There is oil/water heat exchange in the heat pump. It is impossible to remove and solve the scale problem, and the service life cannot be guaranteed.

The water heater uses its own patented technology, 98% of the scale can be transferred to the water tank, and can be periodically drained by hand. The remaining 2% of the scale cleaning is very simple, and it can be operated manually for 30 minutes in 3 months. After 1-2 years, it can be completed by manually cleaning 3~4.

4. Control the oil temperature and protect the air compressor.

The oil temperature during the operation of the air compressor is between 80 ° C and 90 ° C or even higher. If the oil temperature is too high, the service life of the air compressor will be reduced, and the waste heat recovery of the air compressor will reduce the oil temperature of the air compressor to about 60 °C-65 °C, which is more conducive to the operation of the air compressor, thus making the air compressor life. More than 10 years.

5. Increase the gas production of air compressors by 8~10%.

The gas production of the screw air compressor will decrease as the operating temperature of the unit increases. In actual use, the mechanical efficiency of the air compressor will not stabilize at 80 ° C calibration of the gas production. For every 1 °C increase in temperature, the gas production will decrease by 0.5%, the temperature will increase by 10 °C, and the gas production will decrease by 5%. The air compressors with air-cooling and heat dissipation all operate at 88-96 °C, and the decrease is in 4-8. %, summer is even worse. The air compressor unit of the screw air compressor waste heat recovery system can control the oil temperature of the air compressor to be between 80-86 °C, which can increase the gas production by 8%~10%, and greatly improve the operating efficiency of the air compressor.
