Preferred oblique flow refraction separator of described vapor-liquid separation and oblique fire cyclone separator constitute.
Preferred variable speed electric motors, particularly control device of the pneumatic system of described eddy flow and oblique fire eddy flow variable air rate blower fan constitute.
Described condensate water piece-rate system can be made of drip tray, condensate water control device and solution control valve.
In the preferred version, also be provided with the anti-defrosting system of the negative temperature that prevents the heat exchanger frosting of low temperature broadband.The anti-defrosting system of described negative temperature can be made of solution pool, spray pump control device and spray thrower, and spray thrower is positioned at heat exchanger top, low temperature broadband, the vapor-liquid separation top, and solution pool should place safeguards frame underneath.
The present invention is the frostless low level heat source absorber in a high efficiency broadband, both can absorb airborne low level heat source heat under low temperature environment, can provide the evaporation low-temperature receiver that is higher than 2 times of cooling towers in summer again; Or/and the source pump combination can be refrigeration machine or/and heat pump provides renewable cold (heat) energy, realize high efficiency cooling and heating with refrigeration unit, winter, heating temperature can reach 30 ℃ under auxiliary thermal source conditions such as no boiler.
Runnability of the present invention is stable, and is reliable, non-corrosiveness, energy-conservation environmentally safe.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to accompanying drawing, present embodiment comprises safeguards framework 1, safeguards that framework 1 comprises tower body framework 1-1, and tower body framework 1-1 top is provided with chimney fan 1-2, and sidewall is provided with maintenance panel 1-3, maintenance panel 1-3 is provided with air intake grid 1-4; Be provided with the pneumatic system 2 of eddy flow that constitutes by variable speed electric motors, particularly control device 2-1, oblique fire eddy flow blower fan 2-2 among the chimney fan 1-2; Safeguard to be provided with the low temperature broadband heat exchanger 3 that is made of broadband fin 3-1, heat exchanger tube 3-2 in the framework 1, low temperature broadband heat exchanger 3 is provided with inlet 3-3 and liquid outlet 3-4; Heat exchanger 3 tops, low temperature broadband are provided with the vapor-liquid separation 4 that is made of oblique flow refraction separator 4-1 and oblique fire cyclone separator 4-2; Heat exchanger 3 belows, low temperature broadband are provided with the condensate water piece-rate system 5 that is made of drip tray 5-1, condensate water control device 5-2 and solution control valve 5-3; Also be provided with the anti-defrosting system 6 of the negative temperature that is made of solution pool 6-1, spray pump control device 6-2, spray thrower 6-3, spray thrower 6-3 is positioned at heat exchanger 3 tops, low temperature broadband, vapor-liquid separation 4 belows, and solution pool 6-1 is positioned at and safeguards framework 1 below.
Operation principle:
Cryogenic air in the pneumatic system of eddy flow 2 bumpy weathers, make Cryogenic air safeguard framework 1 bottom from the thermal source tower, by air intake grid 1-4, enter low temperature broadband heat exchanger 3, the broadband fin 3-1 of low temperature broadband heat exchanger 3 passes to heat exchanger tube 3-2 with sensible heat and latent heat, passes to the interior circulation solution of pipe by the tube wall of heat exchanger tube 3-2 again, as source heat pump heat, discharge the sensible heat between formation broadband fin 3-1 heat-transfer area and the surrounding air and the exchange of latent heat then via vapor-liquid separation 4.
From the low temperature circulation solution that is lower than environment temperature 6-8 ℃, enter low temperature broadband heat exchanger 3, obtain to be lower than environment temperature 2-3 ℃ solution, discharge the thermal source of low potential temperature sensible heat source as the low heat heat pump.
When ambient air temperature was higher than 1.0 ℃, relative air humidity was bigger, " latent heat " content height, the low temperature broadband heat exchanger 3 airborne large quantity of moisture that when carrying out heat exchange, condensed, and condensate water piece-rate system 5 can be discharged the moisture that condenses automatically.
When ambient air temperature is lower than 1.0 ℃, relative air humidity is less, meet cold for preventing humid air, heat exchanger 3 frostings of low temperature broadband, the anti-defrosting system 6 of negative temperature is according to design temperature control requirement, and automatic spray environmental protection anti-freezing solution reduces low temperature broadband heat exchanger 3 surperficial freezing points, anti-freezing solution after the dilution treats after the low thermoperiod that spray concentrates or adopt reverse osmosis concentrated compression apparatus to concentrate certainly.
