Description

Commercial style open and close type heat source tower heat pump complexes

Technical field

The commercial style open and close type heat source tower heat pump complexes that type of the present invention is related to be related to China's new energy source energy-saving technology, Environmental protection and the big field of resource two.

New energy source energy-saving technology:By summer efficient open type crossflow cooling tower and winter high-performance enclosed finned coil heat source tower It is combined into one, retains respective performance advantage.The psychrometric difference that enclosed difunctional heat source tower summer is generated using solar energy conversion, External water body liquid film evaporation cooler improves cryocooled efficiency;It is wet that winter utilizes medium module group built in finned coil to absorb Harl haze air can be as the heat source of heat pump, and economic and environment-friendly substitution fossil energy, winter comparison conventional air source heat pump utilizes empty Clammy heat source ability in gas improves 90% or more, the external cooling refrigeration of water body liquid film evaporation cooler comparison hot wind of summer system 50% or more energy conservation.The present apparatus is integrated with supercooling accumulation of heat defrosting system, Winter heat supply load system, cooling in summer load system phase The optimal combination of mutual correlation realizes the extensive use of large commercial air-conditioning system a century single cooler upgrading heating pump, can be in air - 15 DEG C of temperature or less areas are all efficiently applied and are reduced by fossil energy for thermogenetic carbon emission, can be in air themperature- It efficiently applies and reduces fossil energy for thermogenetic carbon emission in 15 DEG C or more areas 30-50%.

Environmental protection and resource:Winter is wet in the difunctional heat source tower absorption haze of northern China haze weather application open and close type Cooling and Heat Source purifies haze air as heat pump low level heat source source while taking heat.

Background technique

As the improvement of people's living standards, requirement of the people to architectural environment is also higher and higher.Various refrigeration air-conditioners are logical Wind and heat supply process are increasingly promoted the use of under construction, in current energy-saving low-carbon, are reduced haze weather, are created ecological city Under the big form that city, green ecological district, green low-carbon are built, low-carbon environment-friendly section of the heat source tower as cold (heat) the source source of heat pump Energy heat-supplying mode, will play key player in the development of people's production and living.However it is aobvious in the investigation of longtime running project Show:

Conventional open type heat source tower(Similar open cooling tower constructs), directly formed in filler surface in the tradition that summer retains The cooling high efficiency of liquid film evaporation.However low temperature position heat directly is absorbed in filler surface liquid film using external circulation solution in winter Source, it is also more serious than Pollution of Boiler that matter melts process water capacity drift pollution corrosive environment metal.It is absorbed in air using frozen soln Clammy heat source, solution analyses wet dilution discharge and causes certain water pollution, while solution dilution causes in solution concentration freezing point It rises, heat pump unit frost heave damages phenomenon frequent occurrence, and the loss of solution year accounts for 20% or more of Winter heat supply operating cost.

There is also deficiencies for novel closed type heat source tower complexes, utilize the low close economic temperature difference finned tube exterior heat in broadband in winter For device by the circulating heat transfer to the clammy air of haze, obtaining has the low level heat source of catharsis as heat atmospheric environment The heat source of pump is economic and environment-friendly, the pollution without external circulation solution to environment, the highly dense fin heat of the frosting probability temperature difference bigger than tradition Pump has dropped 90% or more using the energy in air.However in cooling in summer cooling procedure, need to spraying and sprinkling evaporation cooling water The meticulous maintenance of the water process of stringent scale inhibition algae removal is carried out, once operation maintenance management is out of control, is formed in scale+algae+air Jelly covering fin pipe surface seriously affects heat-transfer effect and reaches 20% or so, lowers cryocooled performance.Air negative temperature Period sprays frost prevention using outer spray Polymer Solution, and dilute solution reverse osmosis concentration increases the complexity of system.

It thus solves to improve heat source tower heat pump technology, becomes the pass for promoting and applying heat source tower heat pump technical substitution fossil energy Key.The high efficiency that technical requirements heat source tower summer should have external filler spraying and sprinkling evaporation cooling, winter should have built-in circulation molten Liquid by the economic different transfer of heat in broadband and air circulation, then reduce obtained while frosting probability improves efficiency it is net to atmospheric environment The economy of change effect, the optimal relevance combination between equipment are directly related to the economic security stability of heat source tower heat pump.

Inventing type content

Type commercial style open and close type heat source tower heat pump complexes purpose of the present invention.Summer is directly circulating water body to be utilized to exist Filler surface forms liquid film evaporation, improves circulating water body cooling high efficiency and resistant to pollution feature;Winter is to utilize broadband Economic temperature difference finned tube exterior heat device obtains the low level heat source for having catharsis to atmospheric environment by the circulating heat transfer of air Heat source as heat pump.The present apparatus is integrated with supercooling accumulation of heat defrosting system, Winter heat supply load system, cooling in summer load system Be mutually related optimal combination, realizes the extensive use of large commercial air-conditioning system a century single cooler upgrading heating pump, can be in sky All efficiently substitution fossil energy supplies thermogenetic carbon emission in temperature degree -15 or less area, can be in air themperature -15 with Shangdi Area 30-50% efficiently substitutes fossil energy for thermogenetic carbon emission.

It is compared with conventional open type heat source tower, winter absorption low level heat source, external circulation solution liquid-can be efficiently solved The gas exchange matter process of melting causes solution water capacity to be drifted about, and pollutes environmental corrosion metal serious problems, and solution also than Pollution of Boiler Year loss accounts for 20% or more of Winter heat supply operating cost and drops below 2%, reaches built-in circulation solution and is not taken heat setting to bear water Dilution, solution concentration stablize the safety for having ensured heat pump unit.

It is compared with novel closed type heat source tower, recirculated cooling water of the summer without water process can be efficiently solved in finned tube table Face spraying and sprinkling evaporation is cooling, and jelly covering fin pipe surface seriously affects heat-transfer effect and reaches in formation scale+algae+air 20% or so, cryocooled performance issue is reduced, the simple interests supercooling accumulation of heat defrosting system of accessory device system does not have external molten Liquid participates in system operation.

It is of the invention economical, reasonably run, can thoroughly solve that current China's heat source tower pump open cooling tower is fatal to be lacked Performance issue caused by point and closed type heat source tower finned coil vulnerable to pollution influence.Commercial style open and close type heat source tower heat pump is at suit Innovative technology is set, mating safe and reliable economy can be provided for the association of heat source tower heat pump technology maturation affiliated facility and protects Barrier.
