Steam or hot water type lithium bromide absorption cooling and warming water machine

Abstract

The invention relates to the air conditioning system which is the steam or the hot-water cold water machine of absorbing the lithium bromide. It includes the refrigerator of absorbing the lithium bromide, the flow pipe of the refrigerator which is connected with the return pipe and passes the evaporator; the weak solution pipe of the absorber connected with the generator. The steam pipe of the greenhouse cryogen and the concentrated solution pipe of the greenhouse are set between the evaporator or the absorber and the generator which are all installed with the cold-warm switch valve. The invention has improved the utilization ratio of the steam or the hot-water absorbing single cold unit and decreased the initial investment, the pollution to the environment.

Description

(1) Technical field: [0001] The invention relates to an air-conditioning cooling and heating system, in particular to a lithium bromide absorption refrigeration unit. (two) background technology: [0002] The steam or hot water type lithium bromide absorption refrigerator uses water as the refrigerant, lithium bromide solution as the absorbent, waste heat such as steam or hot water as the compensation heat source, and uses the refrigerant to evaporate in the evaporator to absorb the heat in the air-conditioning water. Lithium bromide The solution absorbs the refrigerant vapor, and transfers the heat in the water vapor to the cooling water, releasing it to the atmosphere. Then, the diluted solution is heated and concentrated in the generator with a compensating heat source, the separated refrigerant is evaporated again, and the concentrated solution is absorbed again, so that continuous circulation can realize continuous refrigeration. Lithium bromide absorption chillers are...

AI Technical Summary

Problems solved by technology

[0003] 1. The design of the air conditioning system is too complicated, and the overall cost has also risen sharply

If the area of ​​the machine room increases, the construction cost will increase; if the system piping increases, the design and construction costs will increase; if a separate heating unit is required, the initial investment cost of the equipment will increase

[0004] 2. The utilization rate of equipment is greatly reduced

If the depreciation rate of the single-cooling unit is calculated according to the life cycle of the bromine chiller, A% / 2 is used when it is running and idle, so the depreciation rate is doubled when the equipment is idle.

[0005] 3. The maintenance cost of the air conditioning system increases
