Flow chart of absorption chiller

Sanyo G-type steam lithium bromide absorption chiller is composed of evaporator, absorber, condenser, low temperature regenerator, high temperature regenerator and heat exchanger, heat recovery device, solution pump, refrigerant pump, etc.

How it works

The cold water in the evaporator is cooled by the low-temperature refrigerant water after the decompression and throttling from the condenser. The refrigerant water itself absorbs the heat of the cold water and evaporates to become refrigerant vapor. It enters the absorber and is absorbed by the solution. The concentrated solution becomes Dilute solution.

The dilute solution in the absorber is pumped to the heat exchanger and heat recovery device, and then the temperature rises, and finally enters the regenerator, where the dilute solution is heated and concentrated into a concentrated solution. The concentrated solution passes through the heat exchanger, the temperature drops, enters the absorber, drips on the cooling water pipe, absorbs the refrigerant vapor from the evaporator, and becomes a dilute solution. On the other hand, in the regenerator, the water vapor generated after the lithium bromide solution is heated by external steam enters the condenser to be cooled, and after decompression and throttling, it becomes low-temperature refrigerant water, which enters the evaporator, and drops on the cold water pipe. , To cool the cold water entering the evaporator.

The above cycle is repeated so as to finally achieve the purpose of preparing low-temperature cold water.

Crew Management Instructions

During operation

1. Although there is an automatic control device, it still needs daily inspection and regular maintenance.

2. Regularly check the PH value of lithium bromide solution and the content of corrosion inhibitor.

3. If the water quality cannot meet the requirements, corresponding measures should be taken.

Long-term downtime

1. If negative pressure protection is used in the machine, check and record the pressure in the gas cylinder displayed on the touch screen on time. If leakage occurs, deal with it in time.

2. For positive pressure inspection, nitrogen must be used.

3. Clean and dry the inside of the copper pipe of the water system in time to protect it.

Make sure to prevent steam from entering the unit.
