Adopt the utility model discloses the water in water collector and the drain pipe can be effectually got rid of, effectually frost -proof purpose is played.
Description
Technical field
The utility model relates to a kind of antifreeze evaporation cooling type cold water unit, belongs to mechanical field.
Background technology
Existing evaporation cooling type cold water unit; what anti-frost protection adopted is manual ball valve; when ambient temperature is lower, unit is shut down for a long time, needs moisturizing ball valve to turn off, manually drainage ball valve is opened; water inside water collector is drained only; Deng water drain clean after again drainage ball valve is shut, in order to avoid before start next time when moisturizing water miss from discharge outlet, need before waiting start again first moisturizing ball valve to be opened; carry out moisturizing, mend and start shooting again to suitable water level.But this kind of method has the following disadvantages: first, water inside the just water collector that drainage ball valve is discharged, water inside water collector to pump tube is due to lower than drainage ball valve, so cannot discharge, the water staying the inside can freeze, damage water lines, can water pump be damaged when again opening, well can not play the effect of anti-frost protection; Secondly, what existing anti-frost protection adopted is ball valve, adopts manual operation, carries out if misoperation there will be moisturizing draining simultaneously, waste resource.
Utility model content
Utility model object: the purpose of this utility model is to solve above the deficiencies in the prior art, provides a kind of automation antifreeze evaporation cooling type cold water unit.
Technical scheme: the antifreeze evaporation cooling type cold water unit of one described in the utility model, comprise heat exchange coil, packing layer, water collector, water pump, PLC mainboard, normal-closed electromagnetic valve and normal-open electromagnetic valve, described packing layer is arranged on below heat exchange coil, described water collector is arranged on below packing layer, described normal-open electromagnetic valve is arranged on the minimum point of water collector discharge outlet, described normal-closed electromagnetic valve is arranged on water supplement port, coordinate with the moisturizing ball valve in water collector, described normal-open electromagnetic valve is connected PLC mainboard with normal-closed electromagnetic valve, described water pump connects the discharge outlet by drainpipe water collector, cooling water in water collector is extracted out.
After adopting this device, due to draining employing is normal-open electromagnetic valve, is arranged on the minimum point of water system, when ensureing draining, the water inside water collector and waterpipe is all drained only; Secondly what moisturizing adopted is normal-closed electromagnetic valve, is arranged on water supplement port side, with floating ball valve of rehydration with the use of.When unit is energized, normal-open electromagnetic valve is just closed, and normal-closed electromagnetic valve is opened, and ball-cock assembly can't detect water level, now starts moisturizing, and water level adds to correct position.
In order to solve the problem further, also comprise temp probe and electric heater, described temp probe is arranged on discharge outlet place, the other end connection PLC mainboard of water collector, and described electric heater is arranged in water collector, the other end connects PLC mainboard.
Whether PLC mainboard is too low by the water temperature in temp probe detected set hydrophone, and time too low, electrical heating is started working, and when water temperature rises to rational position, unit is opened.When unit shuts down power-off for a long time, normal-closed electromagnetic valve is opened, and normal-open electromagnetic valve closes, and unit drains water inside water collector and water lines automatically only.When the unit short time shuts down, whether PLC mainboard is too low by the water temperature in temp probe detected set hydrophone, time too low; electric heater is started working; ensure water temperature in the reasonable scope, in order to avoid freeze in water tank or water pipe when unit starts again, play the effect of anti-frost protection.
Beneficial effect: antifreeze evaporation cooling type cold water unit described in the utility model, structure is simple, and can reach the water emptied completely in unit, reach antifreeze object, the operating process of automation is accurate, laborsaving.
Accompanying drawing explanation
Fig. 1 is the first detailed description of the invention structural representation of the present utility model.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
See Fig. 1, the antifreeze evaporation cooling type cold water unit of one described in the utility model, comprise heat exchange coil 11, packing layer 12, water collector 1, water pump 9, PLC mainboard 3, normal-closed electromagnetic valve 4 and normal-open electromagnetic valve 2, described packing layer 12 is arranged on below heat exchange coil 11, described water collector 1 is arranged on below packing layer 12, described normal-open electromagnetic valve 2 is arranged on the minimum point of the drainpipe 10 of water collector 1, described normal-closed electromagnetic valve 4 is arranged on water supplement port 7, coordinate with the moisturizing ball valve 8 in water collector 1, described normal-open electromagnetic valve 2 is connected PLC mainboard 3 with normal-closed electromagnetic valve 4, described water pump 9 connects the discharge outlet of water collector 1 by drainpipe 10, cooling water in water collector 1 is extracted out, temp probe 5 and electric heater 6, described temp probe 5 is arranged on the discharge outlet place of water collector 1, the other end connects PLC mainboard 3, described electric heater 6 is arranged in water collector 1, the other end connects PLC mainboard 3.
During use, after adopting this device, when unit is energized, normal-open electromagnetic valve 2 is just closed, and normal-closed electromagnetic valve 4 is opened, and moisturizing ball valve 8 can't detect water level, now starts moisturizing, and water level adds to correct position; Whether PLC mainboard 3 is too low by the water temperature in temp probe 5 detected set hydrophone 1, and time too low, electric heater 6 is started working, and when water temperature rises to rational position, unit is opened.When unit shuts down power-off for a long time, normal-closed electromagnetic valve 4 is opened, and normal-open electromagnetic valve 2 closes, and unit drains water inside header tank 1 and water lines automatically only.When the unit short time shuts down, whether PLC mainboard 3 is too low by the water temperature in temp probe 5 detected set water tank 1, time too low; electric heater 6 is started working; ensure water temperature in the reasonable scope, in order to avoid freeze in water collector 1 or water pipe when unit starts again, play the effect of anti-frost protection.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
