Description
Technical field
The present invention relates to a kind of urban original wastewater that utilizes as cold and heat source, to building heat, the source of sewage dedicated for heat pump unit and the system thereof of air-conditioning.
Background technology
Utilizing urban original wastewater as heat pump low level Cooling and Heat Source, for the building heating air-conditioner has the important energy saving and the value of environmental protection, be alleviation energy resource consumption anxiety, alleviate one of effective way of environmental pollution, but contain a large amount of dirty foreign material in the native sewage water, as under the situation of any processing, directly enter source pump and carry out heat exchange, its evaporimeter or condenser are easy to blocked, and unit can't normally move.
In addition, contain materials such as a large amount of hairs, fiber, silt in the urban original wastewater, these materials are often less than filtering mesh diameter, behind system's long-play, also many by hair, the fiber of screen pack, enter evaporimeter or condenser after, just be trapped in the influent side of heat transmission equipment, stop up heat exchanger tube, running time is long more, stops up serious more.
If add heat transmission equipment in the middle of adopting, be that sewage and intermediary's water carry out heat exchange (intermediary's hydromining system's demineralized water), intermediary's water enters source pump again and carries out heat exchange, owing to increased by a cover heat exchange system, temperature after summer intermediary's water and the native sewage water heat exchange will exceed about about 5 ℃ of native sewage water, temperature after winter intermediary's water and the native sewage water heat exchange will be lower than about about 5 ℃ of native sewage water, directly advancing source pump with native sewage water carries out heat exchange and compares, the efficient of source pump is relatively low, in addition, intermediary's water and sewage carry out heat exchange, intermediary's water-circulating pump and middle heat transmission equipment have been increased, this also is initial cost and the operating cost that has increased whole heat pump, and the floor space of machine room is also bigger.
Summary of the invention
For solve native sewage water directly advances evaporimeter or condenser stops up easily, middle heat exchange influence source pump efficient and evaporimeter, when summer in condenser winter, pipeline switched, pollution the invention provides a kind of source of sewage dedicated for heat pump unit and system thereof mutually.
