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 relates to relate to the large field of China's new energy source energy-saving technology, environmental protection and resource two.

New energy source energy-saving technology: by efficient for summer open type crossflow cooling tower and winter high-performance enclosed finned coil heat source tower unite two into one, retain respective performance advantage.Closed-type double action crank press function heat source tower utilizes solar energy to transform the psychrometric difference produced summer, and external water body liquid film evaporation cooler improves cryocooled efficiency; Utilizing winter finned coil built-in medium module group to absorb clammy haze air can as the thermal source of heat pump, economic environment-friend substitution fossil energy, contrasting conventional air source heat pump winter utilizes the clammy thermal source ability in air to improve more than 90%, summer system external water body liquid film evaporation cooler contrast hot blast cooling refrigeration energy-conservation more than 50%.This device was integrated with cold accumulation of heat defrosting system, Winter heat supply load system, cooling in summer load system are mutually related best of breed, realize the extensive use of large commercial air-conditioning system century-old single cooler upgrading heating pump, can all apply efficiently in air themperature less than-15 DEG C area and reduce by fossil energy for thermogenetic carbon emission, can apply efficiently in air themperature more than-15 DEG C area 30-50% and reduce fossil energy for thermogenetic carbon emission.

Environmental protection and resource: absorb the clammy thermal source of haze at the difunctional heat source tower of northern China haze weather application open and close type winter and originate as heat pump low level heat source, purify haze air while heat-obtaining.

Background technology

Along with the raising of people's living standard, the requirement of people to architectural environment is also more and more higher.Various refrigeration air-conditioner ventilates and heat supply process is promoted use day by day under construction, at current energy-saving low-carbon, reduce haze weather, under creating the large form of ecocity, green ecological district, green low-carbon building, the low-carbon environment-friendly energy-saving heating mode that heat source tower is originated as heat pump cold (heat) source, will play key player in the development of people's productive life.But in longtime running project investigation display:

Conventional open type heat source tower (similar open cooling tower structure), directly forms the high efficiency of liquid film evaporation cooling at filling surface in the tradition retained summer.But utilizing external circulation solution directly to absorb low level heat source at filling surface liquid film in the winter time, it is also more serious than Pollution of Boiler that matter melts process water capacity drift pollution corrosive environment metal.Utilize the clammy thermal source in frozen soln absorption air, solution is analysed wet dilution discharge and is caused certain water pollution, solution dilution causes solution concentration freezing point to rise simultaneously, and source pump frost heave damage phenomenon often occurs, and the loss of solution year accounts for more than 20% of Winter heat supply operating cost.

Novel closed type heat source tower complexes also Shortcomings, utilize broadband low crammed Ji temperature difference finned tube exterior heat device by the circulating heat transfer to the clammy air of haze in the winter time, obtain the thermal source economic environmental protection of low level heat source as heat pump atmospheric environment to catharsis, do not have external circulation solution to the pollution of environment, frosting probability utilizes the energy in air to have dropped more than 90% than the highly dense fin heat pump of traditional large temperature difference.But in cooling in summer cooling procedure, need the meticulous maintenance of water treatment spraying and sprinkling evaporation cooling water being carried out to strict scale inhibition algae removal, once operation maintenance management is out of control, form jelly in incrustation scale+algae+air to cover finned tube surface and have a strong impact on heat-transfer effect and reach about 20%, lower cryocooled performance.Adopt the frost prevention of outer spray Polymer Solution spray during air negative temperature, dilute solution reverse osmosis concentration adds the complexity of system.

Thus solve and improve heat source tower heat pump technology, become the key applying heat source tower heat pump technical substitution fossil energy.Technical requirement heat source tower should have the high efficiency of external filler spraying and sprinkling evaporation cooling summer, built-in circulation solution should be had winter circulated by the economic different transfer of heat in broadband and air, reduce the economy of acquisition to atmospheric environment catharsis while frosting probability is raised the efficiency again, the optimal relevance combination between equipment is directly connected to the economic security stability of heat source tower heat pump.
