Description
Technical field
The utility model relates to a kind of closed type heat source tower water receiving and divides the water liquid collecting circulatory system, can receive the various liquid that fallen by heat source tower top simultaneously, comprise the anti-icing fluid spraying under shower water when the rainwater, the summer that fall into tower body by heat source tower air outlet while raining are carried out spraying cooling, the condensed water that fallen by heat exchanger surface under wet cooling condition ruuning situation winter, frost prevention in winter operating mode, and by rainwater with condensed water automatic-discharging, automatic the circulation fluid such as shower water and anti-icing fluid collection is recycled.
Background technology
At present, closed type heat source tower heat pump type air conditioning system is widely used as a kind of novel air-conditioning system, it utilizes closed type heat source tower to carry out in summer that vaporation-type coolingly provides heat pump low-temperature receiver, carry out heat convection winter provides source heat pump heat, thereby is conducive to save the area, saves initial cost, reduces energy consumption, reduces environmental pollution.Because closed type heat source tower must operate in natural environment, be subject to the impact of outside climatic environment larger.Simultaneously closed type heat source tower will be born heat radiation in summer, two kinds of different functions of heat-obtaining in winter, there will be in the course of the work the multi-state working condition such as spray operating mode, the dry cooling condition in winter, wet cooling condition, frost prevention operating mode, frozen condition, defrosting operating condition in summer.
Closed type heat source tower in summer work, the cooling water that flows in heat exchanger coils, blower fan sucks extraneous air from air guide hole, carry out heat exchange by heat exchanger; Shower water is sprayed at heat exchanger coils and fin surface by spray system, carries out enhanced heat exchange, and shower water falls into heat source tower bottom drip tray and again sends into spray system by feeding spraying pump and carry out circulated sprinkling after heat exchanger.Cooling water in heat exchanger coils transfers heat to air and shower water, and temperature reduces, thereby offers heat pump main frame as low-temperature receiver.
In working in the winter time, the lower circulation solution of freezing point that flows in heat exchanger coils, blower fan sucks extraneous air with heat exchanger and carries out heat exchange from air guide hole, and circulation solution absorbs the heat of extraneous air, and temperature raises, thereby provides thermal source for heat pump main frame.If circulation solution temperature is higher now, heat exchanger coils and fin surface temperature are lower than environment dry-bulb temperature higher than environment wet-bulb temperature, and heat exchanger surface can dewfall, and heat source tower moves under dry cooling condition; If circulation solution temperature is lower now, heat exchanger surface temperature is lower than dew-point temperature higher than 0 ℃, and now heat exchanger surface there will be dewfall phenomenon, and this kind of operating condition is called wet cooling condition, under wet cooling condition, heat exchanger surface condensed water can drop down onto in water accumulating disc along fin, needs continuous blow-down.If low, the heat exchanger surface temperature of circulation solution temperature is lower than 0 ℃ now, heat exchanger surface there will be frost, for preventing its frosting, need to from spray system, spray spray solution that freezing point is lower at heat exchanger surface to reduce heat exchanger surface freezing point, spray solution falls into drip tray and again sends into spray system by feeding spraying pump and carry out circulated sprinkling after heat exchanger, and this is frost prevention operating mode.If do not spray frost prevention, but operation continuously in frosting situation, frost layer generates gradually, thickeies, and this is frozen condition.Because the thermal resistance of frost layer is larger, heat source tower service behaviour reduces gradually, need the processing (can be undertaken by modes such as heating heat exchanger surfaces) that defrosts of heat exchanger surface, heat exchanger surface frost layer becomes solidifying water and drops in drip tray after melting, and this is defrosting operating condition.
Can find out from above situation, current heat source tower is during summer and winter operation, and due to the function difference that heat source tower provides, heat source tower need to be changed under different operating modes.Especially in the winter time,, when heat source tower moves under different operating modes, heat source tower replaces by having spray liquid, condensed water the phenomenon producing mutually.In the time that heat source tower transfers wet cooling condition to from dry cooling condition, there is condensed water to produce and need to be discharged into external environment condition, in the time transferring frost prevention operating mode to by wet cooling condition, anti-icing fluid need to be added in heat source tower and carry out circulated sprinkling, can not be discharged in environment and go.In the time that frozen condition finishes to defrost, the condensed water melting under defrosting operating condition also needs to be discharged in environment.So, in closed type heat source tower drip tray, there will be sometimes condensed water, be sometimes spray anti-icing fluid, be the situation of condensed water after frost melts sometimes.Condensed water needs discharge, and anti-icing fluid need to reclaim and circulate, and recycling of the generation of condensed water and discharge and anti-icing fluid is to be all subject to weather condition impact, neither one concrete with reference to saying, thereby brought certain influence for the operation of heat source tower.
In the closed type heat source tower using at present, employing be all same drip tray, bottom connects a storage tank.In summer condition, shower water is contained in storage tank, and the water that Sprayer Circulation pump directly extracts in storage tank sprays.Because drip tray communicates with atmosphere, thereby rainwater directly falls into drip tray by fan outlet and enters storage tank when rainy, causes the pollution to storage tank water quality and then accelerates the fouling and corrosion of heat exchanger surface.In the winter time, sleet can enter into too drip tray and cause same impact.In the winter time in service, often adopts the mode of " primary emission, once fill, discharge again, again fill " to coagulate the discharge of water and the use of anti-icing fluid at present.Be that ambient temperature is when not too low, unified disposable discharge condensed water, in the time that needs carry out frost prevention processing, storage tank is full of to anti-icing fluid, water circulating pump is opened and is carried out frost prevention processing, and in the time not needing frost prevention to process, the discharge of carrying out condensed water after anti-icing fluid is taken out is not (if anti-icing fluid takes out, condensed water can enter into anti-icing fluid cause anti-icing fluid freezing point raise), next time need again anti-icing fluid circulation time again carry out anti-icing fluid fill.Meanwhile, while being stored in storage tank due to anti-icing fluid, owing to communicating with atmosphere, there will be the phenomenon of moisture evaporation, cause viscosity excessive, cause water pump operation unstable.
As can be seen from the above,, in the use of closed type heat source tower, owing to there are rainwater, condensed water, these several fluids of different nature of spray liquid in tower, need selective discharge and collect circulation.And the at present discharge of rainwater is not all carried out but directly blending is in storage tank, the solidifying discharge of water is all to carry out according to workman's experience with the filling of anti-icing fluid, does not even discharge coagulating water in some cases.Caused thus the heat exchanger structure of heat source tower serious, heat exchange efficiency is low, anti-icing fluid freezing point the rises more serious consequence such as rapid, further affected the operating efficiency of heat source tower heat pump main frame.
