Technical field
The present invention relates to a kind of high energy efficiency dead-beat sewage source heat pump unit and system thereof, this device is applied to native sewage water
Source heat pump air-conditioning system, using the native sewage water containing the cold and hot energy of certain low level as the Cooling and Heat Source of heat pump, is consumed by compressor
A small amount of power extraction out carries out heating for building, the capital equipment of cooling.
Background technology
The energy is the important substance basis that human society is depended on for existence and development, finds and utilizes the new regenerative resource to be
Solving energy-intensive one effective way, exploitation urban original wastewater, as heat pump low level Cooling and Heat Source, supplies for building
Warm, cooling has the important energy-conservation and value of environmental protection, and to alleviating, energy resource consumption is nervous, it is significant to alleviate environmental pollution.
But containing substantial amounts of dirty foreign material and fiber and hair in native sewage water, as without any process or do not take clogging-preventing measures
In the case of, it is directly entered heat-exchange apparatus and carries out heat exchange, it is easy to blocking heat-exchange apparatus, it is impossible to properly functioning.
At present, the comparison of sewage source heat pump air conditioning system employing indirect type is many, i.e. sewage and clear water passes through sewage heat exchanger
Heat exchange, then entered ordinary hot pump assembly heat exchange by clear water, indirectly utilizing the heat in sewage or cold, this indirect utilization is dirty
The system of water adds Intermediate Heat Exchanger, adds the cost of system and the floor space of equipment；Owing to using indirect heat exchange system
System, necessarily causes the clear water temperature entering unit winter less than sewage temperature, enters the clear water temperature of unit summer higher than sewage
Temperature, and clear water circulation needs water pump as power, so comparing with directly utilizing sewage, supplies equal heat or cold
Amount, the energy of consumption is many, and this most necessarily improves the operating cost of system.
In order to ensure dead-beat sewage source heat pump system can heat supply, also can cooling, sewage is completely isolated with end system,
When needing dead-beat source pump winter, summer switching, using the mode of coolant switching, at present, the small unit of coolant switching is adopted more
With four-way change-over valve, large-scale unit it is difficult with this mode.
It addition, the sewage entering heat exchanger after Guo Lving still contains a small amount of hair, fiber and greasy filth, a small amount of hair,
Fiber easily blocks heat exchanger tube water inlet, and the heat transfer effect causing heat exchanger is bad, and greasy filth then can adsorb at heat exchanger tube inwall, shadow
Ring heat exchange.
Summary of the invention
For solving the dirty foreign material that contain in native sewage water and fiber and hair, as without any process or do not take to prevent
In the case of stifled measure, block heat-exchange apparatus；Indirect heat exchange system investments is high, it is big to take up an area, energy consumption is high；The heat exchanger tube mouth of pipe easily blocks up
Plug, heat exchanger tube inwall absorption greasy filth affect heat exchange, the invention provides one high energy efficiency dead-beat sewage source heat pump unit and
Its system.
