LG Hot Water Absorption Chiller

Main feature

1. LG patented technology microcomputer fully automatic control, powerful remote monitoring software.

2. Monitor the solution concentration and automatically adjust the operating state parameters of the unit to cooperate with the automatic crystal melting device to prevent crystallization.

3. The self-purifying solution refrigerant dripping device does not consume electricity or block, and prevent the attenuation of cooling capacity.

4. The cooling capacity can be steplessly adjusted within the range of 10%-100%.

5. With imported key components, the unit can operate stably for up to 20 years.

6. Compact and optimized structure design, smaller volume and lighter weight.

7. Low installation requirements, indoor, outdoor, roof, basement can be used.

8. Stable operation, low noise, low vibration, even without anchor bolts.

9. The solution pump is fully automatic frequency conversion adjustment, which is more power-saving for some loads.

10. Auto-ejection type upper and lower cylinder double air extraction system, easy and complete air extraction.

How Refrigeration Works

The main body is composed of a generator, a lower cylinder composed of absorption, a condenser, and an upper cylinder of the generator set; solution heat exchanger, solution pump, refrigerant pump, air extraction system, etc. The main body is in a vacuum state when the refrigerator is working. In the evaporator, the low-temperature refrigerant water absorbs the heat of the cold coal water from the user, so that the temperature of the cold coal water is reduced: at the same time, the refrigerant water evaporates into refrigerant vapor. In the absorber, the lithium bromide solution absorbs the cold steam in the evaporator to dilute the solution. The dilute solution is heated by the solution heat exchanger under the action of the solution pump, and finally sent to the high pressure generator for heating.

In the high-pressure generator, the dilute solution is heated by high-temperature hot water to become a high-temperature intermediate solution; at the same time, a large amount of high-temperature refrigerant vapor is generated. The concentrated solution enters the absorber after heat exchange with the low-temperature dilute solution in the absorber through the solution heat exchanger. At the same time, the generated refrigerant vapor enters the condenser to be cooled and becomes low-temperature refrigerant water. The refrigerant water enters the evaporator after being throttled by the pressure drop, thus completing a cycle.
