Description

Multi-functional central air-conditioning cooling recirculation system

Technical field: the utility model relates to a kind of device of central air-conditioning cooling water recirculation system, belongs to water-treatment technology field.

Background technology: at present, known central air-conditioning cooling recirculation system is to be linked in sequence with pvc pipe and to be formed by condenser, environmental protection cooling tower, coolant pump.When hot water that condenser is sent after the heat radiation of environmental protection cooling tower, be back to coolant pump, and constantly circulate by cooling water by coolant pump.Because the environmental protection cooling tower is forcibly in the process of atmosphere discharges heat, evaporate big water gaging, calcium ion concentration etc. is constantly increased, when calcium carbonate nucleus length is above to 10um, will crystallization separate out (looking into) from " chemical treatment of worn-out open circulation cooling water system "---Chemical Industry Press, simultaneously, airborne impurity also can constantly be mixed in the cooling water, along with cooling water constantly concentrates, very easily cause the long algae of condenser fouling and living bacterium, therefore its water treatment must drop into anticoagulant, corrosion inhibiter etc., its water quality is dirty and poisonous, and pH value is generally about 6.Existing cold water process does not filter out its impurity, makes the condenser fouling easily.

Summary of the invention:

The purpose of utility model: the purpose of this utility model provides a kind of central air-conditioning cooling water recirculation system device, the hot water that it not only can be sent condenser obtains cooling, and can change existing cold water process method, and reach and purify water, conserve water, electricity, utilize heat energy.

Technical scheme: the purpose of this utility model is achieved in that serial connection water processing establishment and swimming pool in existing central air-conditioning cooling water recirculation system device, promptly is formed by connecting with the pvc pipe and the gate valve of corresponding caliber in proper order by condenser, environmental protection cooling tower (being connected to bypass pipe), water processing establishment (comprise and mix coagulating basin, filtering ponds), swimming pool, coolant pump.When central air-conditioner host operates in higher load condition, the hot water that condenser is sent is delivered to the environmental protection cooling tower through pvc pipe, its water outlet is delivered to quartz sand filtration pond through mixing after coagulating basin is handled with the coagulant that is added, filtering layer filters out the impurity in the cooling water, filter back water is through the extremely big resistance water distribution system arm eyelet of filtering layer supporting layer, deliver to Rinsing Area by water distribution system clear water outlet pipe (band valve), deliver to the phytal zone water distribution tube seat of swimming pool again with pvc pipe, after the heat radiation of the swimming pool water surface, water after will being cooled by pvc pipe by swimming pool profundal zone delivery port causes coolant pump, and by coolant pump cooling water is constantly circulated.When central air-conditioner host operates in general load condition, stop the environmental protection cooling tower, the hot water that condenser is sent is delivered to the mixing coagulating basin through pvc pipe by environmental protection cooling tower bypass pipe, delivers to the quartz sand filtration pond with the coagulant that adds after mixing coagulation.In like manner, cooling water is after filtering delivered to the phytal zone water distribution tube seat of swimming pool, behind swimming pool water surface cooling heat dissipation, by pvc pipe swimming pool water is caused coolant pump by the phytal zone delivery port, and by coolant pump cooling water is constantly circulated.So both can make hot water obtain cooling, but economical environment-protective cooling tower power consumption and water loss again.When change between swimming pool delivery port and the water inlet apart from the time, just can reduce water surface area of dissipation, improve the cycle-index of unit interval interior phytal zone water, reach the raising water temperature, the purpose of favourable wintertime swimming.Annotate: southern annual three, four, five and nine, ten, the heated pool best results created of November; The cool cycles water temperature is brought up to 30 ℃ from 25 ℃, and central air conditioner main machine needs the electric energy (looking into from " handpiece Water Chilling Units "---Science Press) of many consumptions 3% approximately.In the technical program, though swimming pool and cooling tower impurity and the transpiring moisture in use can entrained air, but added coagulant (as aluminum sulfate or alum) at the mixing coagulating basin, generate the calcium sulfate precipitation thing as calcium ion meeting and aluminum sulfate chemically reactive, therefore cooling circulating water is when the quartz sand filtration link of process the technical program, its impurity can (lower limit is removed in the filter tank can reach 1-5um in filtering layer by amputation, look into from " water hygiene and treatment technology "---Chemical Industry Press), delivery turbidity can reach about 1NTU (when temperature is higher, swimming pool is enabled its sand cylinder filtration system simultaneously, water quality can be better), and water treatment such as other daily disinfection of swimming pool, its water quality is very good, does not therefore need to add anticoagulant and corrosion inhibiter in cooling water, has promptly changed existing cold water process method.

Beneficial effect: at half fever and chills weather, utilize heat energy, improve water temperature, favourable swimming; The circulating filtration link of the technical program can replace the circulated filter system of swimming pool special configuration or alleviate its circulating filtration load, reaches the purpose of using electricity wisely; Can save electricity consumption of former environmental protection cooling tower electric machine and water loss; Because water quality is good, can make the air-conditioner host condenser less scaling, guarantees its heat exchanger effectiveness; Can prolong the service life of machinery equipment; And environmental protection etc.
