Description
Technical field
The utility model relates to a kind of central air conditioning water system, particularly about a kind of central air conditioning water system that automatically can carry out scrubbing to filter.
Background technology
In recent years, economical develops the large area construction having driven the heavy constructions such as hotel, hotel, market, office building rapidly, and central air conditioner system is able to general promoting the use of.Central air conditioner system crosses by air channel the mode that wind or hot water pipe connect multiple end by a main frame to control different rooms to reach the object regulating room air, adopt central air conditioner system effectively can improve the quality of room air, the generation of prevention air conditioner disease.Central air conditioner system is effective owing to having, and it is convenient to control, the advantage that range of application is large and firmly get people's favor.
Central air conditioner system can be divided three classes: central air conditioning water system, central air-conditioning fluorine system and central air-conditioning wind system.Wherein, central air conditioning water system take water as medium, more comfortable than traditional fluorine system, is generally used for heavy construction or big-room and luxury housing project house and villa, based on high-end house.Central air conditioning water system is a half small-sized centralized fan coil system, and each room fan coil is connected with water chiller-heater unit by pipeline, and the hot and cold water relying on water chiller-heater unit to provide is to supply cold-peace heat supply, and indoor load is all born by water chiller-heater unit.Central air conditioning water system flexible arrangement, independent modulability is good, and comfort level is very high, can meet the needs of complicated house type dispersion use, each room independent operating.In addition, central air conditioning water system novel at present is also one of best solution of floor heating system application, by the effective combination with floor heating, the mode of low water temperature large area low-temp radiation heating in employing, more more comfortable than traditional fan-coil heating system energy-conservation.The quality that central air conditioning water system runs is directly connected to the result of use of tail end of central air conditioner user, therefore, ensures that the quality of central air conditioning water system running environment seems particularly important.
Filter for installation on central air conditioning water system pipeline is one of requisite vitals on central air conditioning water system pipeline; it plays vital effect to the protection of end-equipment and pipeline; but; after filter for installation uses for a long time; because impurity, dirt etc. constantly gather, need regularly to carry out clearing up or changing.Cleaning abatement processes mode at present for the filter for installation on central air conditioning water system pipeline has two kinds: one is in non-air-conditioning season, the i.e. inoperative period of central air conditioning water system, detachable maintaining is carried out to each pipeline of central air conditioning water system, in the process, filter for installation on central water-system pipeline by air is dismantled, to carry out cleaning or changing; Another kind is in air-conditioning season; when filter for installation gathering more impurity dirt; when having had influence on the normal operation of central air conditioning water system; cleaning or the replacing of filter for installation must be carried out; now system-down Maintenance and Repair will be carried out; to clean filter for installation or to change, to maintain the follow-up normal operation of central air conditioning water system.But; no matter adopt which kind of mode above-mentioned, when cleaning filter for installation or changing, central air conditioning water system all needs to carry out shutdown work; and very large inconvenience is there is in cleaning or Renewal process, the normal use of central air conditioning water system must be had influence on.
In addition, Chinese patent notification number is the utility model patent " automatic sewage discharging device for filter of central air conditioning water system " of CN201540059U, disclose a kind of device filter of central air conditioning water system being carried out to automatic pollution discharge, its high-velocity flow utilizing pressure inlet to produce, filter for installation is washed away, thus realizes the cleaning to filter for installation.But, this patent utilizes the current speedup in central air conditioning water system pipeline to reach scrubbing object, but the increase of water velocity, can cause the stability that central air conditioning water system runs, and therefore also must affect the result of use of user, in addition, in depolluting processes, because water velocity is difficult to control, wayward to the degree of scrubbing, easily damage is caused to filter, adverse effect is brought to the normal use of central air conditioning water system.
