Summary of the invention
The purpose of this utility model provides a kind of follow-on water defrosting and the cold heat transfer technology scheme of evaporation, to solve the problem that prior art exists.The technical scheme that the utility model adopted is: the cold and defrosting water heat-exchanger rig of a kind of modified evaporation, comprise the water filter that connects by pipeline, water solenoid valve, air-cooler, Water Check Valve, the defrosting water tank, evaporation cold water storage cistern and defrosting water pump, the import of defrosting water pump is connected with the defrosting water tank, the defrosting exit of pump is connected with the Water Check Valve import, the Water Check Valve outlet connects the water filter inlet by the water supply standpipe, the water filter outlet connects the water solenoid valve inlet, the water solenoid valve outlet connects the air-cooler water inlet, the air-cooler discharge outlet connects drainpipe, drainpipe connects the defrosting water tank, it is characterized in that described modified evaporates cold and defrosting water heat-exchanger rig also comprises the heat exchange water pump, heat exchanger and tapping pipe, described heat exchanger is arranged in the evaporation cold water storage cistern, the import of described heat exchange water pump is connected with pipeline with the defrosting water tank, the outlet of the heat exchange water pump heat exchanger import interior with being arranged on the evaporation cold water storage cistern is connected with pipeline, heat exchanger exit is connected with pipeline with the defrosting water tank, and described tapping pipe is connected between the water supply standpipe and defrosting water tank that is connected with the defrosting exit of pump.
Cold and the defrosting water heat-exchanger rig of a kind of modified evaporation described in the utility model is characterized in that described defrosting water tank and evaporation cold water storage cistern branch are arranged.
Cold and the defrosting water heat-exchanger rig of a kind of modified evaporation described in the utility model is characterized in that described water filter is a Y type water filter.
Cold and the defrosting water heat-exchanger rig of a kind of modified evaporation described in the utility model is characterized in that described heat exchanger is a pipe heat exchanger.
Core of the present utility model is: the evaporation cold water storage cistern is constant, and the defrosting water tank is chosen by the defrosting water yield, increases a low discharge and satisfy the heat exchange water pump of lift and evaporating in the cold water storage cistern heat exchanger to be set and to carry out heat exchange between defrosting water tank and evaporation cold water storage cistern.
With prior art be to the beneficial effect that relatively the utlity model has:
The utility model can make the coolant-temperature gage in the defrosting water tank control effectively in the reasonable scope, guarantees the defrosting effect, does not produce water smoke when making defrosting in the freezer, protection storehouse body structure; The defrosting water tank is not owing to need consider to evaporate cold water internal circulating load, and water tank capacity can reduce greatly, thereby reduces investment; Evaporating the cold water pump that carries does not need to remove, only need between water tank and water tank, to add a little heat exchange water pump, heat exchange water pump and evaporation water supply pump all power sums also are significantly smaller than the pump power that evaporation cold water storage cistern and defrosting water tank share a water tank, can reach is 1/5th of evaporation cold water storage cistern and the defrosting water tank pump power that share a water tank, thereby reduces operating cost; Guarantee the water quality of defrosting water, this heat-exchange system defrosting water does not directly contact with evaporation cold water, can not produce the situation of pollution defrosting water such as the impurity that evaporates in the cold water, microorganism; Evaporate cold the use and carry water tank and water circulating pump, its unlatching is only controlled by refrigeration system; Because of being provided with tapping pipe, make water in the defrosting water supply standpipe into defrosting water tank that can directly reflux, water not in the water supply standpipe, the pipe vibration that does not exist pipeline to freeze and cause because of water hammer.
