Abstract
A central air conditioner set with open-loop water circulation features that cold water is filled into water tank of fan coiled pipe by water pump of main unit through water inlet pipe, the flow of cold water flowing through coiled pipe type heat exchanger is ensured by the water pump of fan coiled pipe, which also makes the cold water flow back to water tank through return pipeline. When flow of cold water filled into fan coiled pipe's water tank is excess its inlet is blocked by float ball valve, and when flow of cold water in return pipeline is too less, the pressure control by-pass is opened to make part of cold water directly return to refrigerator of main unit. Multiple fan coiled pipes can be connected to water inlet and return pipelines.
Description
The present invention relates to a kind of open type water circulation central air-conditioning unit.Particularly be applicable to the open type water circulation central air-conditioning unit that residential building or other adopt small size zone degree warm in nature to regulate.
Existing water circulation central air-conditioning unit because chilled water circulates, for the equilibrium of the discharge that guarantees each section of pipeline, need carry out accurate reducing design to pipeline in the guard system of a sealing.The installation more complicated of this kind equipment also need dispose a drip pipe road simultaneously.
It is simple to the purpose of this invention is to provide a kind of mounting means, does not need to be provided with condensate line, is applicable to the open type water circulation central air-conditioning unit that residential building or other adopt small size zone degree warm in nature to regulate.
The present invention is achieved in that the main frame water pump is injected chilled water the water tank of fan coil by inlet pipeline.The water pump of the fan coil flow of chilled water of coil exchanger that can guarantee to flow through, and make chilled water get back to water tank by water return pipeline.When injecting the blower fan buret chilled-water flow of case be excessive forever.Water tank level raises, and its water inlet pipe mouth is blocked by ball-cock assembly.When the water return pipeline chilled-water flow was too small, inlet pipeline pressure increased, and the pressure control bypass between inlet pipeline and water return pipeline is opened, and makes the part chilled water directly get back to the main frame water tank.The condensed water of fan coil enters the chilled water circulation line by a check valve.Main frame advances on the water return pipeline can connect many typhoons coiler.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing.
With reference to accompanying drawing.In an embodiment, main frame (23) has a water storage box (5), and during water storage box (5) chilled water quantity not sufficient, ball-cock assembly (6) is opened, by filling pipe (1) amount of makeup water.Chilled water enters inlet pipeline (12) after heat exchanger (9) and refrigeration machine (22) carry out heat exchange under water pump (8) effect.Can many typhoons coiler in parallel (21) on inlet pipeline (12) and the water return pipeline (11).Chilled water is got back to water storage box (5) by water return pipeline (11) by the water storage box (14) of inlet pipeline (12) injection fan coil (21) after coil exchanger (17) and room air carry out heat exchange under water pump (13) effect.Blower fan (16) provides the air quantity through tube coil type heat exchanger (17).
When the chilled-water flow that injects water storage box (14) was big than the carrying capacity of water pump (13), the liquid level of water storage box (14) raise, and ball-cock assembly (15) blocking-up chilled water is entered the mouth of pipe of water storage box (14) by inlet pipeline (12).The condensed water on condense water disk (18) tray pipe heat exchanger (14) surface.Condense water disk (18) has a bypass of being with check valve (20) with the input of water pump (13).When the liquid level of condense water disk (18) is higher, to close by the shutoff valve (19) of the level control of condense water disk (18), check valve (20) water side negative pressure increases, and condensed water enters the chilled water circulation by check valve (20).Water pump (13) is when quitting work, and check valve (24) stops chilled water to be back in the water storage box (14), and check valve (20) stops chilled water to be back in the condense water disk (18).
When the chilled-water flow that enters water return pipeline (11) from fan coil (21) hour, the pressure of inlet pipeline (12) increases, the part chilled water is controlled bypass (10) by pressure and is got back to water storage box (5).
When more condensed water enters the chilled water circulation time, the liquid level of water storage box (5) raises, and unnecessary chilled water is discharged by overflow pipe (2).
Water pump (8) is when quitting work, and check valve (7) stops chilled water to be back in the water storage box (5).Use magnetic valve (3) blocking-up overflow pipe (2) simultaneously, make water storage box (5) liquid level rise to ball-cock assembly (4) and close, to keep the freezing water yield in the water return pipeline (11).
