Degree is in a certain range.
Currently, high voltage direct current converter valve Room air-conditioning system is mainly made of 3 parts: Screw chiller, water circulation system are (main
Be made of circulating pump), air-treatment unit, schematic diagram such as Fig. 1.
Screw chiller, effect reduce the water temperature in water circulation system；The effect of water circulation system is by lower temperature
Water be sent into air-treatment unit, absorb air in heat, then by hot water send back to Screw chiller evaporator cooling；Air-treatment
The effect of unit is to recycle valve hall air constantly, hot-air temperature by heat transfer water supply system when air-treatment unit
It reduces, the air that temperature reduces is again introduced into valve hall.Screw chiller control system is controlled by detection evaporator inflow temperature
Unit Commitment, when unit is for when freezing, unit starting when inflow temperature is higher than certain value, unit to stop when temperature is lower than certain value
Machine.In general, the water capacity of water circulation system is less than normal, entire water system heating and temperature-fall period can be made to be quickly completed, to lead
Screw chiller stop frequency is caused to increase.Electric current when unit starting is 2-2.3 times of rated current, and heating power is to operate normally
When 4-5 times.Therefore unit frequent starting is to accelerate the insulation ag(e)ing of Screw chiller motor so as to shorten unit durability.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, and it is empty to provide a kind of high voltage direct current converter valve Room
Adjusting system, to extend the service life of Screw chiller.
To achieve the above object, the technical solution of the utility model is:
A kind of high voltage direct current converter valve Room air-conditioning system, including Screw chiller, circulating pump, air-treatment unit；The sky
Gas disposal unit is for recycling valve hall air constantly, and heat transfer is to air processing machine when hot-air passes through air-treatment unit
Group cooling line and temperature reduce, temperature reduce air be again introduced into valve hall；The outlet of air-treatment unit cooling line
It is connected with the water inlet of circulating pump, the water outlet of circulating pump is connected with Screw chiller, comes when detecting that circulating pump transmits
Inflow temperature be higher than setting temperature value when, Screw chiller then starts, and air-treatment unit cooling line is sent out
The hot water come cools down, so that hot water becomes cold water, and cold water is sent to entering for air-treatment unit cooling line
Mouthful, it further include bearing water tank, the water inlet of the bearing water tank is connected with the entrance of air-treatment unit cooling line,
The water outlet of bearing water tank is connected with the water inlet of circulating pump.
The water outlet of the bearing water tank is higher than water inlet.
The water inlet of the bearing water tank is provided with the bottom end of bearing water tank, and the water outlet of bearing water tank is provided with
The top of bearing water tank.
The pressure-bearing pressure of the bearing water tank is not less than 0.6MPa.
The utility model compared with prior art, the beneficial effect is that:
The utility model can increase water in the case where space occupied very little by adding a bearing water tank more
So as to extend heat exchanging process the initiation culture of Screw chiller is effectively reduced, and then can subtract in the water capacity of the circulatory system
Slow screw machine motor insulation ag(e)ing rate, extends screw machine service life.
Detailed description of the invention
Fig. 1 is the composition schematic diagram of the high voltage direct current converter valve Room air-conditioning system of the prior art；
Fig. 2 is the composition schematic diagram of the high voltage direct current converter valve Room provided by the embodiment of the utility model air-conditioning system；
In figure: 1, Screw chiller；2, circulating pump；3, air-treatment unit；4, bearing water tank；100, valve hall.
Specific embodiment
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment:
As shown in fig.2, the high voltage direct current converter valve Room provided in this embodiment air-conditioning system includes Screw chiller 1, circulation
Pump 2, air-treatment unit 3.
Wherein, for the air-treatment unit 3 for recycling 100 air of valve hall constantly, hot-air passes through air-treatment unit 3
When heat transfer to air-treatment unit cooling line and temperature reduce, temperature reduce air be again introduced into valve hall 100；It is empty
The outlet of 3 cooling line of gas disposal unit is connected with the water inlet of circulating pump 2,1 phase of water outlet and Screw chiller of circulating pump 2
Connection, when detecting that circulating pump 2 transmits the inflow temperature come higher than the temperature value set, Screw chiller 1 then starts, will
The hot water that 1 cooling line of air-treatment unit is sent out cools down, so that hot water becomes cold water, and cold water is passed
It send to the entrance of 3 cooling line of air-treatment unit.That is, high voltage direct current converter valve Room air-conditioning provided by the present embodiment
System is basic identical with existing high voltage direct current converter valve Room air-conditioning system, the difference is that, height provided by the present embodiment
