Background technology
At present directly the brand-new wind air-treatment of vaporation-type unit adopts air as cold (heat) source more, and its major defect is, the unit refrigeration efficiency is lower than EER (heating performance coefficient COP), utilizes the low level heat energy ability, and energy utilization rate is low, and operating cost is higher.Especially, also there is the problem of defrosting in unit under heating condition.These are all limiting the brand-new wind air-treatment of direct vaporation-type unit applying in civilian and similar applications building to a certain extent.
In family life, high-temperature domestic wastewater, as shower waste, directly discharging causes energy dissipation on the one hand under higher temperature, on the other hand environment is caused thermal pollution.
Summary of the invention
Problem to be solved by this invention is to overcome the defective that prior art exists, and a kind of brand-new air processing system of direct vaporation-type with high-temperature domestic wastewater as cold cold (heat) source is provided.Utilize the heat energy of family's high-temperature domestic wastewater, improve self operating mode, improve the operational efficiency of new blower fan group; Can also make that water carries out heat exchange on high-temperature domestic wastewater and the city, utilize high-temperature domestic wastewater heat energy, the preheating domestic water.
The present invention is with the brand-new air processing system of direct vaporation-type in high-temperature domestic wastewater as cold cold (heat) source, comprise the brand-new wind air-treatment of direct vaporation-type unit outdoor heat exchanger, also comprise insulation header tank, filter, heat exchanger, heat preservation storage water tank and one-level water pump, secondary water pump; The suction hose of described one-level water pump is established described filter, and the water sucking mouth of one-level water pump places the bottom of insulation header tank; The one-level pump drain pipe inserts heat preservation storage water tank behind heat exchanger; The suction hose mouth of pipe of secondary water pump places the heat preservation storage water tank bottom, and the drainpipe of secondary water pump is with the brand-new wind air-treatment of the heat exchange mode direct vaporation-type of process unit outdoor heat exchanger; Another road pipeline of heat exchanger is delivered a child and is applied flexibly water lines.
The brand-new wind air-treatment of the direct vaporation-type of the present invention unit adopts water-cooled, with high-temperature domestic wastewater as its cold (heat) source, for summer fresh air refrigerating handle and winter new wind heat processing; Finish the heat exchange of high-temperature domestic wastewater and domestic water in the heat exchanger.Native system is simple and practical, has obvious energy-saving effect, can be widely used in large-scale dwelling house and living area.The present invention directly as cold (heat) source of brand-new blower fan group, replaces air source in the past with high-temperature domestic wastewater, can improve the unit operating mode greatly, improves efficiency.Utilize the heat energy preheating living water of high-temperature domestic wastewater, can reduce the heating energy consumption of water supply.
Description of drawings:
Fig. 1 is the direct vaporation-type brand-new air processing system principle schematic of the present invention with high-temperature domestic wastewater as cold cold (heat) source.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiment:
As shown in Figure 1, the brand-new air processing system of direct vaporation-type with high-temperature domestic wastewater as cold cold (heat) source, comprise the brand-new wind air-treatment of direct vaporation-type unit outdoor heat exchanger 12, also comprise insulation header tank 1, filter 2, plate type heat exchanger 5, heat preservation storage water tank 7 and one-level water pump 3, secondary water pump 14; The suction hose of one-level water pump is established described filter, and the water sucking mouth of one-level water pump places the bottom of insulation header tank; The one-level pump drain pipe inserts heat preservation storage water tank behind plate type heat exchanger; The suction hose mouth of pipe of secondary water pump places the heat preservation storage water tank bottom, and the drainpipe of secondary water pump is with the brand-new wind air-treatment of the heat exchange mode direct vaporation-type of process unit outdoor heat exchanger; Another road pipeline of plate type heat exchanger is delivered a child and is applied flexibly water lines.
Be example here, suppose that sewage temperature is 45 ~ 50 ℃ with life shower waste water.The waste water of partly taking a shower flows into the mouth of pipe that catchments that is positioned at the ground leak when taking a shower, flow in the small-sized insulation header tank 1 through collector pipe, stores therein and is incubated.When needs during for the living water preheating, by the lifting of one-level water pump 3, high-temperature domestic wastewater enters plate type heat exchanger 5 after filtering through filter 2, in plate type heat exchanger with the city of running water system on water 6 carry out heat exchange, with its preheating.The running water of preheating (running water in the water pipe 4) is warmed up to about 27 ℃ by 17 ℃, can directly use.High-temperature domestic wastewater itself is reduced to about 30 ℃, and the two leaves the outlet temperature of heat exchanger high-temperature domestic wastewater and running water, can suitably adjust by adjusting the two water supply ratio.Enter heat preservation storage water tank 7 after the high-temperature domestic wastewater heat exchange, insulation therein stores.
When new blower fan group is opened, to open secondary water pump 14 and make high-temperature domestic wastewater flow into the outdoor heat exchanger 12 of new blower fan group, energy exchange high-temperature domestic wastewater later is through pipeline 13 emission treatment.In summer, outdoor heat exchanger is the condenser of brand-new blower fan group, and sewage is as its low-temperature receiver, because the high-temperature domestic wastewater temperature is about 30 ℃, about 37 ℃ condensation temperature can be provided, and relatively condensation temperature can improve refrigeration efficiency than (EER) greatly 45 ~ 50 ℃ air-cooled new blower fan group.This moment, the course of work of brand-new blower fan group refrigeration system was, the refrigerant gas of low-temp low-pressure is collapsed into the refrigerant gas of HTHP through compressor 10; Through four-way change-over valve 11, inlet chamber external heat exchanger 12 carries out the high temperature condensation; The refrigerant liquid that comes out from outdoor heat exchanger 12 passes through expansion valve 8 throttlings; Enter indoor heat exchanger 9 then and finish evaporation; Refrigerant gas from indoor heat exchanger 9 comes out through four-way change-over valve 11, enters the air entry of compressor 10, finishes whole kind of refrigeration cycle.
In winter, by the adjusting of four-way change-over valve 6, off-premises station transfers the evaporimeter of unit to, and high-temperature domestic wastewater can provide about 23 ℃ evaporating temperature as thermal source, can improve unit heating performance coefficient (COP) greatly equally.This moment, completely newly the course of work of the heating of blower fan group was, the refrigerant gas of low-temp low-pressure is collapsed into the refrigerant gas of HTHP through compressor 10; Through four-way change-over valve 11, enter indoor heat exchanger 9 and carry out the high temperature condensation; The refrigerant liquid that comes out from indoor heat exchanger 9 passes through expansion valve 8 throttlings; Inlet chamber external heat exchanger 12 is finished evaporation then; Refrigerant gas from outdoor heat exchanger 12 comes out through four-way change-over valve 11, enters the air entry of compressor 10, finishes the whole circulation that heats.
