Description

Central air conditioning water system
Technical field
The utility model is related to water-cooled central air-conditioning field, specifically a kind of central air conditioning water system.
Background technology
In central air conditioning water system, system will lead to exhaust when operating, and conventional method is, in water system peak, to install Automatic exhaust steam valve is vented, because system is sealing and circulating, and indoor wind disk and main frame connection water route is complicated, the high-speed motion in pipeline Aqueous vapor be difficult discharge, often make central air conditioner system heat exchange bad and produce high and low pressure failure, water pump is produced cavitation erosion existing As.
Utility model content
The purpose of this utility model is to provide a kind of central air conditioning water system, to improve existing closed central air-conditioning water system System exhausting problem, improves the flow of system water, improves the heat transfer effect of central air-conditioning, improves efficiency.
The technical solution of the utility model is as follows:
A kind of central air conditioning water system, includes the Central Air-condition Refrigerator group for circulating connection successively by pipeline, flow Switch, user load, filter, water pump, check valve, pressure gauge and thermometer, it is characterised in that:Described filter with it is described Transition water tank is connected with connecting line between water pump, the side of the transition water tank upper is provided with to be connected with the filter The water inlet connect, the opposite side of transitional water lower box part is provided with the top of the delivery port being connected with the water pump, transition water tank and set There is exhaust outlet.
Described central air conditioning water system, it is characterised in that:The inside of the transition water tank described entery and delivery port it Between be provided with dividing plate.
Described central air conditioning water system, it is characterised in that:The top of the transition water tank is provided with water supplement port and is connected with Filling pipe.
Described central air conditioning water system, it is characterised in that:The top of the transition water tank is provided with sewage draining exit and is connected with Blow-off pipe.
It is cold(Heat)Water is exported to flow switch by water chiller-heater unit, then to user load(Indoor heat transmission equipment)Changed Heat, the water after heat exchange is by filter to transition water tank, and the water with bubble discharges gas by transition water tank, and makes under the pressure of water Zero is reduced to, increases the flow of system water, is then return to water pump.
Transition water tank can be system exhaust, moisturizing, blowdown, with multi-functional.
The beneficial effects of the utility model:
The utility model is by increasing transition water tank, it is ensured that unit fixed on water pump suction bubble-free, rapidly can arrange system air Totally, and make system return pressure be zero, add the flow of system water, make system reliably working, improve heat exchange efficiency, side System water supplement, blowdown and cleaning.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of central air conditioning water system includes the Central Air-condition Refrigerator for circulating connection successively by pipeline Group 1, flow switch 3, user load 2, filter 4, water pump 5, check valve 6, pressure gauge 7 and thermometer 8, filter 4 and water pump 5 Between connecting line on be connected with transition water tank 9, the side on the top of transition water tank 9 is provided with the water inlet being connected with filter 4 Mouth 10, the opposite side of the bottom of transition water tank 9 is provided with the delivery port 11 being connected with water pump 5, and the top of transition water tank 9 is provided with exhaust Mouth 12.
In the utility model, the inside of transition water tank 9 is provided with dividing plate 13 between entery and delivery port 10,11.
The top of transition water tank 9 is provided with water supplement port and is connected with filling pipe 14.
The top of transition water tank 9 is provided with sewage draining exit and is connected with blow-off pipe 15.
When air-conditioning system is run first, the formation of water pump 5 is cavitated containing air in system, influence heat exchanger heat exchange makes Flow system flow protection act, makes evaporator supercooling icing, when water pump 5, which is powered, to be run, water is in system interior circulation, transition water tank 9 Delivery port 11 in its bottom, transition water tank 9 is in full water without gaseity, sends into water pump 5, after being pressurizeed by water pump 5, then passes through The feeding Central Air-condition Refrigerator of check valve 6 group 1 is freezed or heated, cold(Heat)Water is sent out by Central Air-condition Refrigerator group 1, through excessively stream Amount switch 3, is sent to the heat exchanger at the end of user load 2, for users to use.
If there is gas in system, flow switch 3 will be acted, and the evaporator of Central Air-condition Refrigerator group 1 will be subcooled Freeze, it is cold(Heat)Water is after the heat exchange of user load 2, and system water is gentle, by filter 4, into transition water tank 9, in transition The water inlet 10 of water tank 9 produces aqueous vapor separation, and gas is discharged by exhaust outlet 12, when system water shortage, by the moisturizing of filling pipe 14, When water has dirt or during purging system, system sewage can be released by blow-off pipe 15, when needing purging system, case can be opened Lid, to iterative cycles heated wash such as its interior input cleaning agents, is released finally by blow-off pipe 15.
Water can be discharged rapidly by transition water tank 9, at the same with full-closed system ratio, due to having transition water tank 9, system Become open, the inlet pressure of water pump 5 is zero, in the case where water pump 5 is constant, add the pressure difference of water pump 5, increase water Flow, improves the heat exchange of whole system.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New scope is defined, on the premise of the utility model design spirit is not departed from, and those of ordinary skill in the art are to this Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of the utility model claims determination In the range of.
