Problems solved by technology

[0002] Using sewage as a heat source is very energy-saving, but the biggest technical problem of heat recovery from sewage is: because sewage is used, waste heat recovery from sewage in cold areas will inevitably cause blockage, corrosion, and scaling of heat exchangers, resulting in frequent maintenance, Short life, low heat exchange efficiency and other problems, the use effect is not good. At the same time, the waste heat recovery system of bath sewage contains multiple subsystems, such as heat pump unit system, heat source indirect heat exchange system, fan coil unit, hot water supply system, etc., electromechanical equipment The number is large and scattered, and the temperature, flow and liquid level of multiple measuring points on the hot water loop, brine loop and sewage loop need to be measured at the same time. If the method of decentralized management and local control of measurement is adopted, it will lead to operational management work. The amount is large and the efficiency is low, and the waste heat recovery effect of sewage is not good
