The direct mixing heating unit is to increase the water mixing pipeline on the basis of the direct supply system, and is the heating unit that will mix the primary network high-temperature water with the second water return. It has been widely used in China and abroad in recent years, with the gradual maturity and improvement of the automatic control system, the direct mixing heating unit has overcome the disadvantages such as strong heat source dependence, the primary and secondary system pressure non-isolation, and the balancing difficulty of the thermal network, has a wide application prospect,

The Advantages of Direct Mixing Unit:

Less building investment

Because do not need board change, water supply system, softening water system and so on, the floor area is small, and the construction investment is reduced by 20% to 30%.

       Strong energy-saving potentiality

With a large range of water temperature, it can be used for low quality heat of power plant, which can greatly reduce the cost of heat source. The primary and secondary test of the indirect system will consume 0.1-0.15mpa pressure and increase the power loss. The heat loss of the indirect system is high and the direct mixing system has no heat loss. After the actual operation, the direct mixing unit can save 15% to 30% energy.

        Easy maintenance

The equipment maintenance is greatly facilitated by avoiding the washing and cleaning of the plate and softening water system.
