Description
Technical field
The utility model relates to energy-conservation and technical field of energy utilization, and particularly a kind of open type heat source tower anti-icing fluid being applied to air conditioning and heating industry concentrates temperature elevation system.
Background technology
Heat source tower heat pump system uses due to its summer in winter two Ji Jieke, the features such as operating cost is cheap, takes up room little, and operational effect is good, air conditioner refrigerating and central heating industry growing.In the winter time, need in the recirculated water between heat source tower and heat pump, to add antifreezing agent in heat source tower heat pump system and form anti-icing fluid, (lower than 5 DEG C) heat pump inner icing freezing heat exchanger during to prevent ambient temperature lower.In open type heat source tower; anti-icing fluid directly contacts with the air of low temperature and high relative humidity; in running; anti-icing fluid can entrained by air swiftly flowing in heat source tower, elegant go out heat source tower; low temperature (-4 to-15 DEG C) anti-icing fluid concentration can reduce gradually along with the passing of running time simultaneously; in addition shut down and run duration rainfall snowfall in have sleet to fall into open type heat source tower, anti-icing fluid concentration will reduce further.If do not processed anti-icing fluid concentration, then there will be the phenomenon that anti-icing fluid freezing point rises, heat pump efficiency reduces, severe patient is by freezing heat pump heat exchanger.
At present in order to keep the concentration of anti-icing fluid; engineering adopts usually and directly adds antifreezing agent to the method in anti-icing fluid; in the process of adding antifreezing agent, need system-down to run; artificial or mechanical method is adopted to be added into by antifreezing agent in open type heat source tower; process tedious, formality are numerous and diverse, need to monitor anti-icing fluid concentration at any time in case its excessive concentration or too low.Required antifreezing agent and labour cost is higher, the interpolation time long, add frequency high, system cloud gray model is had an impact, its operability and economy are not high.
For avoiding the problems referred to above, application number is have employed distillation still, preheater, condenser and water tank in the utility model patent " a kind of refrigerating and heating energy-saving system with heat source tower " of 2010202822668, need in actual use to add in a set of heat pump heating system and absorb heat thus carry out high temperature distillation to anti-icing fluid, thickening efficiency is lower.Add initial cost on the one hand, add operating cost on the other hand.Anti-icing fluid simultaneously after distillation needs discharge system, inevitably with antifreezing agent in exudate, thus causes economic loss and environmental pollution.
The mode proposing to utilize superheated refrigerant cool in the application number utility model patent that is 2013103224279 " realizes the heat source tower heat pump device of reactivation heat efficiency utilization " based on air carries out concentrating of antifreezing agent, this kind of mode controls complexity, required system unit is too much, in long-play, the heat of superheated refrigerant is consumed in a large number, the obtainable heat of system reduces, reduce heating efficiency, cause system heat supply not enough.
Application number be 2013103595546 utility model patent " based on vacuum boiling realize regeneration of waste liquor and heat recycling heat source tower heat pump " in propose utilize vacuum boiling realize solution concentrate, the heat that this system utilizes is still from superheated refrigerant, and heating efficiency reduces.Need in concentration process to use vavuum pump to carry out extracting vacuum, need to build air circulation loop etc. in addition.Within the system, system occupy that space is large, Dynamic System and safeguard comparatively difficulty.
How high efficiency, contamination-freely heat source tower heat pump anti-icing fluid is concentrated, ensure that heat source tower heat pump system can normal safe runs, entire system performance keeps stable, design a kind of new and effective, that operating cost is low anti-icing fluid enrichment facility imperative.
In heat source tower group, be connected with balance pipe between each heat source tower collecting-tank to ensure that each heat source tower water yield is average and ensure that each heat source tower there will not be spilling water phenomenon, play the effect holding anti-icing fluid when system-down does not run simultaneously.Owing to having the temperature difference (anti-icing fluid temperature is lower than environment temperature 6 to 8 DEG C) with external environment after shutdown runs, the anti-icing fluid temperature in collecting-tank can slowly rise, but the rate of climb is slower; Also houses anti-icing fluid in pipeline between whole heat source tower group and heat source tower heat pump, after system-down runs, outside managing, carried out Insulation, anti-icing fluid temperature can remain unchanged.When system is started shooting again, whole anti-icing fluid temperature is still lower, causes system boot inefficiency, heating system needs the long period just can reach predetermined temperature, therefore needs whole system to start shooting in advance preheating building, causes unnecessary operating cost thus.
