Description

Spraying system of container type indirect evaporation cooling air conditioning unit

Technical Field

The invention relates to heat exchange equipment of a data center, in particular to a spraying system of a container type indirect evaporation cooling air conditioning unit.

Background

In recent years, along with the development of data centers, the demand on machine room air conditioners is more and more, large refrigerating capacity and large air volume are required, the demand on the machine room air conditioners is high, the heat exchange efficiency is high, the traditional machine room air conditioners cannot meet the demand, and indirect evaporation cooling air conditioning units are produced under the background.

The indirect evaporation cooling air conditioning unit comprises an air-air heat exchanger, an air cooling mechanical auxiliary refrigerating system, an air cooling condenser system and a spraying system. Wherein spray system can carry out rapid cooling to the air in the atmosphere, if spray system can't work set up the damage, so indirect evaporation cold air conditioning unit also can't effectual cooling to data center's indoor air, the indoor temperature that appears data center easily rises fast, takes place dangerous situation easily.

Disclosure of Invention

The purpose of the invention is as follows: the invention aims to provide a spraying system of a container type indirect evaporation cooling air conditioning unit, which is used for solving the problem that the indirect evaporation cooling air conditioning unit cannot be effectively cooled because the spraying system cannot work.

The technical scheme is as follows: the invention relates to a spraying system of a container type indirect evaporative cooling air conditioning unit, which comprises a water tank, wherein the water tank is connected with a water inlet pipe; the water outlet pipe is connected with a spray component, the spray component comprises a circulating water pump and a spray header which are connected in sequence, the circulating water pump is used in pairs, and the circulating water pump and another circulating water pump are connected between the spray header and the water outlet pipe in parallel.

Furthermore, a pressure sensor is arranged in the pipeline of the spray header and feeds back the water pressure in the pipeline of the spray header so as to monitor the working condition of the spray system.

Furthermore, a one-way valve is correspondingly arranged on the pipeline of each circulating water pump, and the one-way valve avoids reverse backflow impact of the system on the pump.

Furthermore, an electronic flow valve is arranged on a pipeline of the spray header and used for monitoring and accurately controlling the flow of the whole spray system.

Furthermore, a water drainage pipe is connected to the water tank and provided with a manual stop valve.

Furthermore, a ball float valve and a manual stop valve are arranged on the water inlet pipe of the water tank and used for water supplement in the water tank.

Furthermore, the spray header is a copper spray header with a atomization effect.

Has the advantages that: compared with the prior art, the invention has the advantages that: two groups of water pumps are selected as one spare, when one group is damaged, the other group continues to work, and the container type indirect evaporation cold air conditioning unit is kept to work continuously; simultaneously automatically supplying water to maintain the water level in the water tank; the flow of the whole spraying system is monitored and accurately controlled by designing the electronic flow valve.

fig. 2 is a structural view of a spray system of a container type indirect evaporative cooling air conditioning unit.

Detailed Description

As shown in fig. 1 and 2, a spraying system of a container type indirect evaporative cooling air conditioning unit comprises a water tank 1, wherein the water tank 1 is connected with a water inlet pipe 2; the outlet pipe connection has spray assembly 3, spray assembly 3 is including the circulating water pump 31, the shower head 32 that connect gradually, and wherein circulating water pump 31 all uses in pairs, and circulating water pump 31 connects in parallel between shower head 32 and outlet pipe with another circulating water pump 31, and wherein shower head 32 is the copper shower head 32 that has the atomizing effect, and whole spray system's pipeline uses PPR pipe and PPR coupling hot melt to constitute, and basin 1 is stainless steel.

In order to observe whether the spraying system works normally, a pressure sensor 4 is arranged in the pipeline of the spraying head 32, and the pressure sensor 4 feeds back the water pressure in the pipeline of the spraying head 32 so as to monitor the working condition of the spraying system.

In order to avoid that water sent by the circulating water pump 31 reversely flows into another circulating water pump 31 to cause reverse backflow impact on the pump when the spraying system works, the pipeline of each circulating water pump 31 is correspondingly provided with a one-way valve 5, and the one-way valve 5 avoids the reverse backflow impact of the system on the pump.

To keep the amount of water sprayed out by the showerhead 32 to a minimum, the air temperature can be lowered to a predetermined temperature; an electronic flow valve 6 is arranged on a pipeline of the spray header 32, and the electronic flow valve 6 monitors and accurately controls the flow of the whole spray system.

When the spraying system is used for trimming, water in the water tank 1 needs to be drained, a water drainage pipe 7 is arranged on the water tank 1, the water drainage pipe 7 is connected to the water tank 1, and a manual stop valve 8 is arranged on the water drainage pipe 7.

In order to be able to realize that the water level of the water tank 1 is kept stable, the water tank 1 is timely replenished with water, a ball float valve 9 and a manual stop valve 8 are installed on the water inlet pipe 2 of the water tank 1 for replenishing water in the water tank 1, and when the water tank 1 is cleaned, the manual stop valve 8 is operated to stop supplying water in the water tank 1.

In actual work, two groups of water pumps 31 are selected to be used as a spare water pump, when one group is damaged, the other group continues to work, and the container type indirect evaporation cooling air conditioning unit is kept to work continuously.
