Supply heat pump heat exchanger are described in detail

2013-9-5 read:2234

Sewage source heat pump system can be widely used in hotels, shopping malls, office buildings, factories and so on, under normal circumstances can use the life sewage, industrial wastewater, dyeing wastewater, wastewater from coal mine and so on to the heat exchanger, the premise is in sewage source heat pump to add centrifugal sewage heat exchanger. According to the air conditioning big market inquiry investigation, the current international common centrifugal sewage heat exchanger with special internal centrifugal gravity reversed structure and anticorrosive coating can do this, skills present there are not domestic anti infarction and erosion resistant anti fouling can do this.

With direct sewage source heat pump system, direct sewage source heat pump system without infarction, erosion, consistent, multiply microbes can, due to centrifugal sewage heat exchanger with anti infarction, prevent erosion, microorganism on reproduction function.

Direct sewage source heat pump of direct type, complex systems and equipment ( heat exchangers, pumps ), therefore, direct cost of the system than that of direct. According to the refrigeration express reporter investigation, in the same water temperature condition, direct sewage source heat pump evaporation temperature than the direct type high2~ 3, the heating can be same situation, direct sewage source heat pump than the direct type energy saving about 7%.

But in the sewage water heat exchanger in the future, project cost is relative progress some, in the use of the time to give full consideration to this point. According to their surrounding the composition of sewage to be thinking and decision.
