Dongguan closed-type cooling tower lowest price

Closed cooling tower, or closed-type cooling tower, also known as closed cooling tower, referred to as closed tower.
The closed cooling tower originates from an evaporative cooler, which is actually a heat exchanger that combines the performance of a water-cooled cooler with a conventional cooling tower, and is a heat exchanger that is bounded between the water cooler and the air cooler, so there are also manufacturers who call it "evaporative air coolers". Now this type of cooling equipment, the common feature is the wall heat exchanger outside spray water and forced ventilation, heat from the wall heat exchanger in the cooling fluid through the wall to the wall of the spray water, and then through the spray water and air forced to circulate to the air, and spray water to the air heat transfer, It is mainly composed of the latent heat of evaporation of spraying water and the hot exchange of the air with the spray water. As a result of the cooling fluid in the inter-wall heat exchanger and the outside process equipment closed circulation flow, for the difference between the cooling fluid directly with the air contact with the general cooling tower, so there is a "closed tower" of the said, and the relative to the general cooling tower is called "Open Tower."
closed Cooling tower (also known as Evaporative air cooler or closed cooling tower) is a tubular heat exchanger placed in the tower, through the flow of air, spray water and circulating water heat exchange to ensure cooling effect. Because it is closed cycle, it can guarantee the water quality is not polluted, very good protection of the main equipment efficient operation, improve the service life. When the outside temperature is low, the sprinkler system can be stopped and water saving effect is achieved. Pushing the implementation of national energy conservation and emission reduction policies and the increasing scarcity of water resources, closed-type cooling towers have been widely used in iron and steel metallurgy, power electronics, machining, air-conditioning systems and other industries in recent years.
two?
1. The cooling principle of the open-type ling Electric Cooling tower is that by spraying the circulating water into the filler of the glass fiber, through the contact between water and air, to reach the heat exchange, and then the fan to drive the air circulation in the tower, the hot gas flow after heat exchange with the water will be brought out to achieve the cooling.
This kind of cooling method, the initial investment compared less, but the operating cost is high (water consumption, electricity consumption).
2. The cooling principle of the closed cooling tower is, in simple terms, two loops: an inner loop, an outer loop. There is no filler, the main core part of the Copper pipe table cooler.
Inner Circulation: Docking with the object device, forming a closed circulatory system (the circulating medium is soft water). Cooling the object device and bringing the heat from the object device to the cooling unit.
outer circulation: In the cooling tower, the cooling tower itself is cooled. Not in contact with the internal circulating water, but only through the cooling tower of the copper tube table cooler for heat transfer heat dissipation.
in this kind of cooling mode, through automatic control, according to the water temperature set motor operation.
two cycles, in the spring and summer two seasons of high ambient temperature, two cycles are required to run simultaneously. In autumn and winter, the ambient temperature is not high, and in most cases only one inner loop is needed.
three
The main difference is whether the water to be cooled is in direct contact with the atmosphere.
Four
the closed cooling tower comes with a sink, and the open cooling tower has no sink and opens the pool at the bottom of the tower.
the closed cooling tower uses a much smaller pump head, head (about) = inlet and outlet water level difference + resistance loss.
open-type cooling tower pump head (approx.) = liquid level of the pool and inlet level + resistance loss.
Open closed Type in many cases can be used at the same time, which can be. Relative, open water quality is better, the area is much larger (pool) investment is bigger (water pump and electricity); closed investment small, occupy less land, water quality easily become bad. are often used in civilian residential central air conditioning, cold storage and industrial plant mining.
Five
Open closed Cooling tower is a cooling device that sprays circulating cooling water in which it is in direct contact with the air and emits heat to the atmosphere by evaporation and convection. The difference between open-type cooling towers and closed-type cooling towers is:?
1. The cooling principle of the open cooling tower: By spraying the circulating water to the glass fiber filler, through the contact between water and air, to achieve heat exchange, and then a fan to drive the tower inside the airflow cycle, will be with the water heat after the hot gas flow out, so as to achieve cooling. 2. The cooling principle of the closed cooling tower: In a nutshell, two loops: an inner loop, an outer loop. No filler, the main core part is the Copper pipe table cooler. Two cycles, in the case of high ambient temperature in spring and summer, two cycles are required to run simultaneously. The ambient temperature is not high in autumn and winter, in most cases only one inner cycle is needed.
① Inner Loop: Cools the object device and takes the heat out of the object device to the cooling unit. It is docking with the object equipment, forming a closed circulatory system (the circulating medium is soft water).
② Outer circulation: under this kind of cooling mode, the motor operation is set according to the water temperature by automatic control. It is in the cooling tower, cooling the tower itself. Not in contact with the inner circulating water, but only through the cooling tower of the copper tube table cooler for heat transfer.
before winter comes, closed cooling towers are likely to experience temperatures below 0 ℃ or 0 ℃, when effective antifreeze measures must be considered, which is a simple and effective means of equipment protection.
Cooling tower Winter Frost prevention problems to do the following measures:

1. Drain the water inside the cooling tower
in general, the cooling tower has the lowest point of discharge, that is, in the winter without use of the case of the water off the tower, in order to prevent the winter outside temperature is too low, causing the coil tube freeze bad.

2. Installation Skills
In order to prevent water in the coil pipe is not clean, residual water in the case of extreme weather frozen, resulting in coil tube rupture, in the construction of the cooling tower installation level to do a slight adjustment, as far as possible to make the coil water point at the lowest points, to reduce the amount of residue.

3, heat tracing cable antifreeze
as the production process is likely to use the cooling tower in the winter, in the design of the cooling water pipe will be added to the Heat trace cable, automatically adjust the water pipe temperature, to prevent the coil tube freeze bad.
    
Air Conditioning cooling system anti-freezing electric tropics working principle is: electric heat tracing cable by conductive polymer composites (plastic) and two parallel metal conductors and insulation sheath of flat ribbon cable electric heat tracing to the fire pipe, water transport pipeline winter freeze-proof insulation to ensure the smooth flow of the pipeline, is an effective method, The use of self-limiting temperature electric tropics. The advantage is: temperature-controlled electricity with tropical cable corresponding to the heating system with automatic adjustment of output power, so it will not be burned due to their own heat, but due to the actual need for heat compensation, so for the next generation of energy-saving thermostat
closed-type cooling tower, evaporative condenser, air cooler, quick-freezing equipment, cooling devices and other equipment to our life has brought greater convenience, but we should also pay attention to the use of cleaning work in order to make the closed cooling tower, evaporative condenser, freezer and other refrigeration equipment better work.
The following is a brief introduction of the closed-type cooling tower maintenance work.
1, cleaning and check the closed cooling tower sprinkler system is blocked, if there is impurities need to rule out clogging phenomenon.
2, should pay attention to clean remove the closed cooling tower filter the existence of dirt.
3. Cleaning
