Unit schematic diagram
Main feature
1. Green and environmentally friendly air-conditioning products.
Using water as the refrigerant and lithium bromide as the absorbent, it runs under vacuum, which is safe and harmless to the human body and the environment. The unit uses steam directly, uses less electrodes, and does not pollute the atmosphere. There are no large moving parts, no vibration in operation, and low noise.
2. Save operating costs.
The unit has super performance, high operating thermal efficiency, and obvious energy saving effect; the normal operating temperature of cooling water can be as low as 15℃, combined with the frequency conversion control of the solution pump, so that the load and the circulating flow of the unit are always balanced, and the partial load efficiency is higher.
3. The operation of the unit is safe and reliable.
The unique vacuum pump-free ejection and air extraction system ensures the vacuum performance and service life of the unit; the automatic monitoring and adjustment system of the solution concentration makes the anti-crystallization protection more effective and ensures the unit's trouble-free operation.
4. The structure of the unit is more compact.
The unit's small size and floor space are beneficial to reduce the initial investment cost of the machine room, the weight is correspondingly reduced, and the hoisting and transportation is more convenient.
5. The amount of solution flushing is small, and the unit starts fast.
The unit is ventilated for 3 minutes, and the cooling capacity can reach 40% of the normal load.
6. The unit structure is sturdy.
In order to adapt to the thermal expansion and contraction caused by the rapid temperature change, the 90-10 copper-nickel alloy U-tube structure is adopted in the high-pressure generator, which prolongs the service life of the heat transfer tube.
7. Some of the conforming characteristics are superior.
The automatic adjustment devices such as solution concentration and flow rate inside the unit always maintain the best working condition of the unit, and the partial load is specified as shown in the figure.

bara RED series direct combustion bromine chiller cycle volume adjustment method
Direct combustion bromine chiller cycle volume adjustment method
There is no circulation control valve on the Ebara Red series direct combustion units, and it is necessary to adjust the solution circulation through frequency correction of the frequency converter.
The solution pump and solution spray pump of this series of units are equipped with separate frequency converters, and both high and low generators are equipped with liquid level electrodes. In summary, when the high generator is in the low liquid level range, the automatic control of the unit will increase the frequency of the solution pump. When the high generator is in the high liquid level range, the frequency of the solution pump will automatically decrease - the frequency will increase or decrease linearly until the liquid level is at the appropriate position, and the solution pump will maintain the current frequency to deliver the solution to the generator, achieving a stable state.
The liquid level control of the low engine is also a similar logic, except that the frequency of the solution spray pump is changed. Another difference is that when the liquid level of the low engine is low, the frequency of the spray pump decreases, while when the liquid level of the low engine is high, the frequency of the spray pump increases.
The logic may seem simple to describe, but there are many parameters that need to be set on the unit panel.
Firstly, whether it is a solution pump or a spray pump, there is a basic frequency, and the reference data for this basic frequency is the difference between the high generator pressure and the outlet pressure of the absorber. There are a total of 7 pressure ranges, namely 0, 16kpa, 31kpa, 46kpa, 61kpa, 76kpa, 91kpa, and 106kpa. There is a default value within each pressure range, which is the initial frequency of the frequency converter under the current working condition - these values can be modified according to the needs of the engineer. Secondly, in addition to the basic frequency, there is an important parameter called the correction amount, which is the frequency of each increase or decrease of the shielded pump when the liquid level is high or low. Generally speaking, at a low liquid level, increase by 2 hz each time until the liquid level is suitable; At a high liquid level, decrease by 1.5 hz each time until the liquid level is suitable. And this' every time 'refers to the correction interval, which is how many seconds the liquid level signal is detected. Both the correction interval and correction amount can be changed. It is worth mentioning that the correction amount has a range limit, and if it exceeds the range, an alarm will be given to indicate that the generator liquid level is not adjusted.
There are many parameters that affect the adjustment of the circulation volume, that is, the frequency adjustment of the frequency converter. The liquid level and pressure difference have been mentioned earlier, and in other settings, we can also choose whether to adjust the frequency of the frequency converter based on the high dew point temperature.
Although it is an independent variable frequency pump and two shielded pumps, the variable frequency of both pumps must be considered when adjusting the circulation volume. Because the Ebara Red series units have a series parallel process, this means that the function of the solution spray pump is to simultaneously transport high and low generation solutions to the absorber. That is to say, assuming that the liquid level of the low generator is high, the spray pump will increase frequency, which will lead to an increase in the circulation volume of the high generator solution and a decrease in the liquid level. Therefore, it is likely that the solution pump will also increase frequency at the same time.
